Occupation Scholar
Nationality American

Joseph John Campbell (March 26, 1904October 30, 1987) was an American mythology professor, writer, and lecturer best known for his work in the fields of comparative mythology and comparative religion. His work is vast and covers many aspects of the human experience, and his philosophy is often identified with the phrase he coined: "Follow Your Bliss".

Childhood and education

Joseph Campbell was born and raised in White Plains, New York in an upper middle class Roman Catholic family. As a child, Campbell became fascinated with Native American culture after his father took him to see the American Museum of Natural History in New York where he saw on display featured collections of Native American artifacts. He soon became versed in numerous aspects of Native American society, primarily in Native American mythology. This led to Campbell's lifelong passion for myth and to his study of and mapping of the cohesive threads in mythology that appeared to exist among even disparate human cultures. He graduated from the Canterbury School (Connecticut) in 1921. While at Dartmouth College he studied biology and mathematics, but decided that he preferred the humanities. He transferred to Columbia University where he received his B.A. in English literature in 1925 and M.A. in Medieval literature in 1927. Campbell was also an accomplished athlete, receiving awards in track and field events.

Europe

In 1927, Campbell received a fellowship provided by Columbia to study in Europe. Campbell studied Old French and Sanskrit at the University of Paris in France and the University of Munich in Germany. He quickly learned to read and speak both French and German, mastering them after only a few months of rigorous study. He remained fluent in both languages for the remainder of his life.

He was highly influenced while in Europe by the period of the Lost Generation, a time of enormous intellectual and artistic innovation. Campbell commented on this influence, particularly that of James Joyce, in The Hero's Journey: Joseph Campbell on His Life and Work (1990, first edition:28):

CAMPBELL: And then the fact that James Joyce grabbed me. You know that wonderful living in a realm of significant fantasy, which is Irish, is there in the Arthurian romances; it's in Joyce; and it's in my life.
COUSINEAU: Did you find that you identified with Stephen Daedalus...in Joyce's A Portrait of the Artist as a Young Man?
CAMPBELL: His problem was my problem, exactly...Joyce helped release me into an understanding of the universal sense of these symbols...Joyce disengaged himself and left the labyrinth, you might say, of Irish politics and the church to go to London, where he became one of the very important members of this marvelous movement that Paris represented in the period when I was there, in the '20s.

It was in this climate that Campbell was also introduced to the work of Thomas Mann, who was to prove equally influential upon his life and ideas. Also while in Europe, Campbell was introduced to modern art, becoming particularly enthusiastic about the work of Paul Klee and Pablo Picasso. A new world of exciting ideas opened up to Campbell while studying in Europe. Here he also discovered the works and writings of Sigmund Freud and Carl Jung. It was also during this time, as well, that he met and became friends with the young Jiddu Krishnamurti, a friendship which began his lifelong interest in Hindu philosophy and mythology. In addition, after the death of Indologist Heinrich Zimmer, Campbell was given the task to edit and posthumously publish Zimmer's papers.

Return to the United States and the Great Depression

On his return from Europe in 1929, Campbell announced to his faculty at Columbia that his time in Europe had broadened his interests and that he wanted to study Sanskrit and Modern art in addition to Medieval literature. When his advisors did not support this, Campbell decided not to go forward with his plans to earn a doctorate and never returned to a conventional graduate program (The Hero's Journey: Joseph Campbell on His Life and Work, 1990, first edition: 54).

A few weeks later, the Great Depression began. Campbell would spend the next five years (1929-1934) trying to figure out what to do with his life (Larsen and Larsen, 2002:160) and he engaged in a period of intensive and rigorous independent study. Campbell discussed this period in The Hero's Journey: Joseph Campbell on His Life and Work (1990, first edition:52-3). Campbell states that he "would divide the day into four four-hour periods, of which I would be reading in three of the four hour periods, and free one of them...I would get nine hours of sheer reading done a day. And this went on for five years straight."

He also traveled to California for a year (1931-32), continuing his independent studies and becoming close friends with the budding writer John Steinbeck and his wife Carol (Larsen and Larsen, 2002, chapters 8 and 9). Campbell also maintained his independent reading while teaching for a year in 1933 at the Canterbury School during which time he also attempted to publish works of fiction (Larsen and Larsen, 2002:214).

Campbell's independent studies led to his greater exploration of the ideas of the Swiss psychiatrist Carl Jung, a contemporary and estranged colleague of Sigmund Freud. Campbell edited the first Eranos conference papers and helped to found Princeton University Press' Bollingen Press. Another dissident member of Freud's circle to influence Campbell was Wilhelm Stekel (1868 - 1939). Stekel pioneered the application of Freud's conceptions of dreams, fantasies of the human mind, and the unconscious to such fields as anthropology and literature.

Sarah Lawrence College

In 1934, Campbell was offered a position as professor at Sarah Lawrence College (through the efforts of his former Columbia advisor W.W. Laurence). Campbell married one of his former students, dancer and dance instructor Jean Erdman, in 1938. He retired from Sarah Lawrence College in 1972, after having taught there for 38 years.

Death

Joseph Campbell died at the age of 83 on October 30, 1987, at his home in Honolulu, Hawaii, from complications due to esophageal cancer shortly after completing filming of The Power of Myth with Bill Moyers.

Select works

James Joyce and early works

As noted above, James Joyce was an important influence on Campbell. Campbell's first important book (with Henry Morton Robinson), A Skeleton Key to Finnegans Wake (1944), is a critical analysis of Joyce's final text Finnegans Wake. In addition, Campbell's seminal work, The Hero with a Thousand Faces, discusses what Campbell termed the monomyth -- the cycle of the journey of the hero, an idea which he directly attributes to Joyce's Finnegans Wake.

The Masks of God

His massive four-volume work The Masks of God covers mythology from around the world, from ancient to modern. Where The Hero with a Thousand Faces focused on the commonality of mythology (the “elementary ideas”), the Masks of God books focus upon historical and cultural variations the monomyth takes on (the “folk ideas”). In other words, where The Hero with a Thousand Faces draws perhaps more from psychology, the Masks of God books draw more from anthropology and history. The four volumes of Masks of God are as follows: Primitive Mythology, Oriental Mythology, Occidental Mythology, and Creative Mythology.

The Historical Atlas of World Mythology

At the time of his death, Campbell was in the midst of working upon a large-format, lavishly illustrated series entitled The Historical Atlas of World Mythology. This series was to build on Campbell’s idea, first presented in The Hero with a Thousand Faces, that myth evolves over time through four stages:

The Way of the Animal Powers -- the myths of Paleolithic hunter-gatherers which focus on shamanism and animal totems.

The Way of the Seeded Earth -- the myths of Neolithic, agrarian cultures which focus upon a mother goddess and associated fertility rites.

The Way of the Celestial Lights -- the myths of Bronze Age city-states with pantheons of gods up ruling from the heavens, led by a masculine god-king.

The Way of Man -- religion and philosophy as it developed after the Axial Age (c. 6th century BC), in which the mythic imagery of previous eras was made consciously metaphorical, reinterpreted as referring to psycho-spiritual, not literal-historical, matters. This transition is evidenced in the East by Buddhism, Vedanta, and philosophical Taoism; and in the West by the Mystery Cults, Platonism and Gnosticism.

Only the first two volumes were completed at the time of Campbell's death. Both are now out-of-print.

The Power of Myth

Campbell's widest popular recognition followed his collaboration with Bill Moyers on the PBS series The Power of Myth, which was first broadcast in 1988, the year following Campbell's death. The series exposed his ideas concerning mythological, religious, and psychological archetypes to a wide audience, and captured the imagination of millions of viewers. It remains a staple of PBS television membership drives to this day. A companion book, The Power of Myth, containing expanded transcripts of their conversations, was released shortly after the original broadcast, and became a best seller.

Thou Art That: Transforming Religious Metaphor

A recent compilation of many of his ideas is titled Thou Art That: Transforming Religious Metaphor. In it Campbell writes:"...Mythology is often thought of as other people's religions, and religion can be defined as mis-interpreted mythology." In other words, Campbell did not read religious symbols literally as historical facts, but instead he saw them as symbols or as metaphors for greater philosophical ideas.

Campbell had previously discussed this idea with Bill Moyers in The Power of Myth:

CAMPBELL: That would be a mistake in the reading of the symbol. That is reading the words in terms of prose instead of in terms of poetry, reading the metaphor in terms of the denotation instead of the connotation.
MOYERS: And poetry gets to the unseen reality.
CAMPBELL: That which is beyond even the concept of reality, that which transcends all thought. The myth puts you there all the time, gives you a line to connect with that mystery which you are (Campbell, 1988:57).

Campbell's original voice

Campbell relied often upon the writings of Carl Jung as an explanation of psychological phenomena, as experienced through archetypes. But Campbell did not necessarily agree with Jung upon every issue, and had very definite ideas of his own.

A fundamental belief of Campbell's was that all spirituality is a search for the same basic, unknown force from which everything came, within which everything currently exists, and into which everything will return. This elemental force is ultimately “unknowable” because it exists before words and knowledge. Although this basic driving force cannot be expressed in words, spiritual rituals and stories refer to the force through the use of "metaphors" - these metaphors being the various stories, deities, and objects of spirituality we see in the world. For example, the Genesis myth in the Bible ought not be taken as a literal description of actual events, but rather its poetic, metaphorical meaning should be examined for clues concerning the fundamental truths of the world and our existence.

Accordingly, Campbell believed the religions of the world to be the various, culturally influenced “masks” of the same fundamental, transcendent truths. All religions, including Christianity and Buddhism, can bring one to an elevated awareness above and beyond a dualistic conception of reality, or idea of “pairs of opposites,” such as being and non-being, or right and wrong. Indeed, he quotes in the preface of The Hero with a Thousand Faces: "Truth is one, the sages speak of it by many names." which is a translation of the Rig Vedic saying "Ekam Sat Vipra Bahuda Vadanthi."

Campbell was fascinated with what he viewed as basic, universal truths, expressed in different manifestations across different cultures. For example, in the preface of The Hero with a Thousand Faces, he indicated that a goal of his was to demonstrate similarities between Eastern and Western religions. In his four-volume series of books "The Masks of God", Campbell tried to summarize the main spiritual threads common throughout the world. Tied in with this, was his idea that many of the belief systems of the world which expressed these universal truths had a common geographic ancestry, starting off on the fertile grasslands of Europe in the Bronze Age and moving to the Levant and the "Fertile Crescent" of Mesopotamia and back to Europe (and the Far East), where it was mixed with the newly emerging Indo-European (Aryan) culture.

Heroes and the monomyth

The role of the hero figured largely in Campbell's comparative studies. In 1949 The Hero with a Thousand Faces introduced his idea of the monomyth (as stated above, a word borrowed from Joyce), which outlined some of the archetypal patterns Campbell recognized. Heroes were important to Campbell because, to him, they conveyed universal truths about one's personal self-discovery and self-transcendence, one's role in society, and the relationship between the two.

THE LAW OF ATTRACTION



The Law of Attraction is commonly associated with New Age and New Thought theories. It posits that one should never dwell on the negative, as the "metaphysical principle of life" is embodied in a "law of attraction" that states "you get what you think about; your thoughts determine your destiny." It is also said that emotions are the factor that increase or decrease the speed of attraction relative to how much you feel about the subject you are attempting to attract.



The phrase Law of Attraction, although used widely by esoteric writers, does not have a consensual definition. However, the general consensus among New Thought thinkers is that the Law of Attraction takes the principal "Like Attracts Like" and applies it to conscious desire. That is, a person's thoughts (conscious and unconscious), emotions, and beliefs cause a change in the physical world that attracts positive or negative experiences that correspond to the aforementioned thoughts, with or without the person taking action to attain such experiences. This process has been described as "harmonious vibrations of the law of attraction", or "you get what you think about; your thoughts determine your experience".

The phrase is closely associated with New Thought beliefs and practices, from which its most common definition arises, but it also has a long standing (and more complex development) in other esoteric fields such as Hermeticism and Theosophy. Recently, the New Thought version was popularized by the 2006 film The Secret.

The more materialistic interpretations of The Law of Attraction have been criticized. The scientific community cites the misuse of the scientific term law and the lack of any scientific evidence for the claims made by advocates for the Law of Attraction, and by some proponents within the New Thought Movement and spirituality in general.

Many people who accept the Law of Attraction as a guide for right living do so on the basis of their faith in the Universe and The Universe's 'Laws'; thus, to them, the nature of the 'Law' is not one to be settled scientifically, and the word 'Law' carries the same belief-based weight as non-scientific 'Laws' from other religions, such as the 'Law of Karma' and the Ten Commandments. This is especially true among those who are adherents of various New Thought. One common way that New Thought adherents utilize the Law of Attraction is through the practice of positive affirmations.

Some proponents of a more modern version of the Law of Attraction claim that it has roots in Quantum Physics. According to them, thoughts have an energy that attracts like energy. In order to control this energy, proponents state that people must practice four things:

  • Know what one desires and ask the universe for it. (The "universe" is mentioned broadly, stating that it can be anything the individual envisions it to be, from God to an unknown source of energy.)
  • Focus one's thought upon the thing desired with great feeling such as enthusiasm or gratitude.
  • Feel and behave as if the object of one's desire is already acquired.
  • Be open to receiving it.

THE FLOWER OF LIFE


the flower of life Cargado originalmente por hinton.jennie

There are many symbols found within the Flower of Life's design, each believed to possess significant meaning.

The Flower of Life has represented important meaning to many people throughout history. It can be found in the temples, art, and manuscripts of cultures from all over the world. The following are some of the locations in which the FOL symbol has been sighted.

Egypt - The Temple of Osiris in Abydos and at Mount Sinai.
Hungary - Magyarország - Carphatians.
Israel - Masada
China - The Forbidden City and various temples.
Japan - Various temples.
India - The Harimandir Sahib (Golden Temple), Hampi, and the temples at Ajanta.
Turkey - Various old Roman sites.
Spain
Austria
Italy - Italian art from the 13th century (Wolfram 2002, p. 43).
North Africa - Morocco
Middle East - Lebanon and various Islamic mosques.
North America - Mexico

Components of the Flower of Life have been a part of the work of Alchemists. Metatron's Cube is a symbol derived from the Flower of Life which was used as a containment circle or creation circle.

Seed of Life


The "Seed of Life" is formed from seven circles being placed with sixfold symmetry, forming a pattern of circles and lenses, which acts as a basic component of the Flower of Life's design.

According to some[who?], the Seed of Life is a symbol of depicting the seven days of creation in which God created life; Genesis 2:2-3, Exodus 23:12, 31:16-17, Isaiah 56:6-8. The first day is believed to be the creation of the Vesica Piscis, then the creation of the Tripod of Life on the second day, followed by one sphere added for each subsequent day until all seven spheres construct the Seed of Life on the sixth day of Creation. The seventh day is the day of rest, known as the "Sabbath" or "Shabbat."

In the 13th century, a Cabalist group from France succeeded, through geometric interpretation, in dividing the entire Hebrew alphabet into an order using the Seed of Life. The resulting alphabet was remarkably similar to that of the Religious sage Rashi who wrote his commentaries on the Old Testament at that time in France.

Vesica piscis

The Vesica Piscis is formed from two intersecting circles of the same diameter, where the center of each circle is on the circumference of the opposite circle. Its design is one of the simplest forms of sacred geometry. It has been depicted around the world at sacred sites, most notably at the Chalice Well in Glastonbury, England, and has been the subject of mystical speculation at several periods of history. One of the earliest known occurrences of the Vesica Piscis, and perhaps first, was among the Pythagoreans, who considered it a holy figure.

According to some religious beliefs[who?], the Vesica Piscis represents the second stage in the creation of the Seed of Life, in that it was constructed by "the Creator" (or "God") through the creation of a second Spherical Octahedron joined with the first. It is said that the Creator's consciousness began inside the first sphere and journeyed outside the surface of that sphere to create the second. Purportedly in reference to this, the Old Testament refers to "the spirit of the Creator floating upon the face of the waters."

Continuing with these beliefs[who?], God is said to have created light through the creation of the second sphere (or Vesica Piscis). "Let there be light" is a relevant excerpt from the Old Testament. The pattern of the Vesica Piscis is said to be a geometric formula which represents the electromagnetic spectrum of light. For further information on how this can be done, see Drunvalo Melchizedek's book, The Ancient Secret of The Flower of Life.

The Vesica Piscis has been called a symbol of the fusion of opposites and a passageway through the world’s apparent polarities. It has also been noted as the geometry for the human eye. It is also known to be the basis for the Ichthys fish, which is a Christian symbol representing "The Son," Jesus Christ.

Tree of Life

The symbol of the Tree of Life may be derived from the Flower of Life. The Tree of Life is a mystical concept, a metaphor for common descent, and a motif in various world theologies and philosophies. This mystical concept has historically been adopted by some Christians, Jews, Hermeticists, and pagans. Along with the Seed of Life it is believed to be part of the geometry that parallels the cycle of the fruit tree. This relationship is implied when these two forms are superimposed upon each other.

The Tree of Life is most widely recognized as a mystical concept within the Kabbalah, which is used to understand the nature of God and the manner in which He created the world ex nihilo (out of nothing). The Kabbalists developed this concept into a full model of reality, using the tree to depict a "map" of creation. The tree of life has been called the "cosmology" of the Kabbalah.

Some believe the Tree of Life of Kabbalah corresponds to the Tree of Life mentioned in Genesis 2:9.

PANTHEISM

Pantheism (Greek: πάν ( 'pan' ) = all and θεός ( 'theos' ) = God) literally means "God is All" and "All is God". It is the view that everything is of an all-encompassing immanent abstract God; or that the universe, or nature, and God are equivalent. More detailed definitions tend to emphasize the idea that natural law, existence, and the universe (the sum total of all that is, was, and shall be) is represented or personified in the theological principle of an abstract 'god'.

History

The term "pantheist"—of which the word "pantheism" is a variation—was purportedly first used by Irish writer John Toland in his 1705 work, Socinianism Truly Stated, by a pantheist. However, the concept has been discussed as far back as the time of the philosophers of Ancient Greece, by Thales, Parmenides and Heraclitus. The Jewish backgrounds for pantheism may reach as far back as the Torah itself in its account of creation in Genesis and its earlier prophetic material in which clearly "acts of nature" [such as floods, storms, volcanoes, etc.] are all identified as "God's hand" through personification idioms, thus explaining the open references to the concept in both New Testament and Kabbalistic literature.

In 1785 a major controversy began between Friedrich Jacobi and Moses Mendelssohn, which eventually involved many important people of the time. Jacobi claimed that Lessing's pantheism was materialistic in that it thought of all Nature and God as one extended substance. For Jacobi, this was the result of the Enlightenment's devotion to reason and it would lead to atheism. Mendelssohn disagreed by asserting that pantheism was the same as theism.

LIGHT GEOMETRY: TESSERACT

In geometry, the tesseract, also called an 8-cell or regular octachoron, is the four-dimensional analog of the cube, which is in turn the three dimensional analog of the square. The tesseract is to the cube as the cube is to the square; or, more formally, the tesseract can be described as a regular convex 4-polytope whose boundary consists of eight cubical cells.

A generalization of the cube to dimensions greater than three is called a “hypercube”, “n-cube” or “measure polytope”. The tesseract is the four-dimensional hypercube or 4-cube.

According to the Oxford English Dictionary, the word tesseract was coined and first used in 1888 by Charles Howard Hinton in his book A New Era of Thought, from the Greekτέσσερεις ακτίνες” (“four rays”), referring to the four lines from each vertex to other vertices. Some people have called the same figure a “tetracube”, and also simply a "hypercube" (although a hypercube can be of any dimension).


Rotating shadow of a tesseract rotating on a single axis
Rotating shadow of a tesseract rotating on a single axis

Geometry

The tesseract can be constructed in a number of different ways. As a regular polytope constructed by three cubes folded together around every edge, it has Schläfli symbol {4,3,3}. Constructed as a 4D hyperprism made of two parallel cubes, it can be named as a composite Schläfli symbol {4,3}x{ }. As a duoprism, a Cartesian product of two squares, it can be named by a composite Schläfli symbol {4}x{4}.

Since each vertex of a tesseract is adjacent to four edges, the vertex figure of the tesseract is a regular tetrahedron. The dual polytope of the tesseract is called the hexadecachoron, or 16-cell, with Schläfli symbol {3,3,4}.

The standard tesseract in Euclidean 4-space is given as the convex hull of the points (±1, ±1, ±1, ±1). That is, it consists of the points:

\{(x_1,x_2,x_3,x_4) \in \mathbb R^4 \,:\, -1 \leq x_i \leq 1 \}.

A tesseract is bounded by eight hyperplanes (xi = ±1). Each pair of non-parallel hyperplanes intersects to form 24 square faces in a tesseract. Three cubes and three squares intersect at each edge. There are four cubes, six squares, and four edges meeting at every vertex. All in all, it consists of 8 cubes, 24 squares, 32 edges, and 16 vertices.

Projections to 2 dimensions

The construction of a hypercube can be imagined the following way:

  • 1-dimensional: Two points A and B can be connected to a line, giving a new line AB.
  • 2-dimensional: Two parallel lines AB and CD can be connected to become a square, with the corners marked as ABCD.
  • 3-dimensional: Two parallel squares ABCD and EFGH can be connected to become a cube, with the corners marked as ABCDEFGH.
  • 4-dimensional: Two parallel cubes ABCDEFGH and IJKLMNOP can be connected to become a hypercube, with the corners marked as ABCDEFGHIJKLMNOP.

This structure is not easily imagined but it is possible to project tesseracts into three- or two-dimensional spaces. Furthermore, projections on the 2D-plane become more instructive by rearranging the positions of the projected vertices. In this fashion, one can obtain pictures that no longer reflect the spatial relationships within the tesseract, but which illustrate the connection structure of the vertices, such as in the following examples:

A tesseract is in principle obtained by combining two cubes. The scheme is similar to the construction of a cube from two squares: juxtapose two copies of the lower dimensional cube and connect the corresponding vertices. Each edge of a tesseract is of the same length. A multitude of cubes that are nicely interconnected. The vertices of the tesseract with respect to the distance along the edges, with respect to the bottom point. This view is of interest when using tesseracts as the basis for a network topology to link multiple processors in parallel computing: the distance between two nodes is at most 4 and there are many different paths to allow weight balancing.

Tesseracts are also bipartite graphs, just as a path, square, cube and tree are.

CLIFFORD STOLL: 18 MINUTES WITH AN AGILE MIND

http://www.ted.com Clifford Stoll could talk about the atmosphere of Jupiter. Or hunting KGB hackers. Or Klein bottles, computers in classrooms, the future. But he's not going to. Which is fine, because it would be criminal to confine a man with interests as multifarious as Stoll's to give a talk on any one topic. Instead, he simply captivates his audience with a wildly energetic sprinkling of anecdotes, observations, asides -- and even a science experiment. After all, by his own definition, he's a scientist: "Once I do something, I want to do something else."

GEORGE E O SEGREDO DO UNIVERSO

from website for George's Secret Key to the Universe!

George's Secret Key to the Universe is an adventure story where all the adventures are based on real science. It is a journey across space to learn more about the Universe in which we live and a journey through physics - the laws that govern the Universe - to understand more about it. But it's also the story of a lonely boy and how his life changes when he meets his new next-door neighbours, Annie and Eric. Annie is mad about the ballet and Eric, her father, is a scientist. Eric works with a computer called Cosmos who is so powerful and so clever he can draw you a doorway, through which you can walk (if you're wearing a space suit that is! It's very cold in space, around -270 C) to any point in the known Universe.

Now, my computer and yours may not be as powerful as Cosmos, but we've still got some wonderful and exciting pictures to show you on our website. You too can see some of the amazing sights in outer space that George discovers. Like George, you can go on a journey to places that no other human being has been before.

Writing this book with my dad, Stephen Hawking was a lot of fun for both of us. So I hope you enjoy George's Secret Key to the Universe and I hope you want to come back to hear more about George's adventures next year, when he takes off once more, destination unknown . . .

Best of luck with your cosmic voyages and remember, Space Rocks!

DRYMARIA JENNIFERAE



Abstract. Drymaria jenniferae is proposed as a new species. It appears to be related to the group "'Arenarioides" by the nature of the indumentum and the 2-8 lobed petals, but differs by its petals with four equal lobes, with the trunk (blade-like portion below lobes and above the basal claw) of each petal widened at the base. The species is notable for the absence of stipules, the cateniform trichomes, and the tuberculate seeds. A description, an illustration, and a key are provided. Key Words: Caryophyllaceae, Drymaria, Mexico.


Municipio de Viesca Coahuila, México

According to the most recent revision (Duke, 1961), the genus Drymaria Willd. ex Schult. (Caryophyllaceae) comprises 48 species mainly in subtropical areas of the Western Hemisphere; one species (Drymaria cordata Willd. ex Schult.) is widespread and occurs in Asia, Africa, Oceania, and Madagascar. The work of Duke (1961) includes a supra-specific classification in 17 series that were not validity published (Hartman, 2005) because they lacked Latin diagnoses and type citations. Since the revision of Duke, Turner (1995) described two new species from northeastern Mexico. Preliminary reports suggest there are 17 species and several infra-specific taxa in the Chihuahuan Desert (Hartman, in prep.). We here describe a new species of Drymaria from the southwestern Chihuahuan Desert Region.

Drymaria jenniferae Villarreal & A. E. Estrada, sp. nov. Type: Mexico. Coahuila: Mun. Viesca, E of Cinco de Mayo, 1600 m, 30 Sep 2006 (ft, ft), G. S. Hinton et al. 28498 (holotype: MEXU; isotypes: ANSM, ENCB, NY, TEX). (Fig. 1)

Drymariae axillari Brandegee similis sed differt petalis breviunguiculatis, doubus in 4 lobos equales bifurcatis, trunco (pars laminaris petalina sub lobis supraque unguem) ad basim leviter, stipulis carentibus, et seminibus lacrifonnibus tuberculatis.

Perennial herbs, the taproot woody, slender; stems originating from the root crown spreading or ascending, 4-8 cm long, branched, glaucous, indumentum hirsutulous, the trichomes septate, uniseriate, cateniform, often glandular. Leaves opposite; petioles 1- 3 mm long, glaucous, with same indumentum as the stems; blades elliptic to ovate, 4-10 x 3-6 mm, slightly succulent, the bases cuneate, decurrent to the petiole, the apices acute; stipules absent. Flowers solitary in distal branch axils; pedicels 3-6 mm long; sepals oblong to broadly elliptic, 4-5x1.8-2.2 mm, lobes, the lobes themselves divided into two cucullate, hirsutulous, the margins scarious, linear nearly equal lobes (each petal thus the apices obtuse; petals ca. 4 mm long, 4-lobed), the trunks (blade-like portion below white, divided half their length into two lobes and above claws) entire, slightly wider at the base, subhastate, the basal claw very short; staminodia absent; stamens 5, 2-3 mm long, the anthers ca. 1 mm long; ovaries ellipsoid, 1.0-1.5 mm long, glabrous, styles trifid, ca. 1 mm long. Capsules ellipsoid, 4— 6 mm long. Seeds 0.8 mm long, lacrimiform, glabrous, black, minutely roughened.

Distribution and ecology.—The species is known only from the type locality in southwestern Coahuila, growing in scattered sparse colonies on gypseous hillsides with only a few plants. The area was visited in 2007, but fertile material was unavailable due to drought. Other species in the area include Thymophylla setifolia Lag., Agave lechuguilla Torr., Fouquieria splendens Engelm., Euphorbia antisyphilitica Zucc, Anulocaulis erioselenus (A. Gray) Standi., Cyphomeris crassifolia (Standi.) Standi., Notholaena greggii (Kuhn) Maxon., Acacia crassifolia A. Gray, Tiquilia greggii (Torr. & A. Gray) A. Richardson, Tiquilia gossypina (Woot. & Standi.) A. Richardson, and Bursera schlechtendalii Engl.

Phenology.—Flowering August to October; fruiting in September and October, probably appearing after the rainy season.

Etymology.—The epithet honors Jennifer Hinton, great-granddaugther of George B. Hinton and a promising plant collector in the Hinton family, a family that has made tremendous contributions to the knowledge of the flora of Mexico (Hinton & Rzedowski, 1972).

The genus Drymaria was last revised by Duke (1961), but needs careful study by modern methods to evaluate Duke's informal classification (Hartman, 2005). Drymaria jenniferae does not fit comfortably within any of the infra-generic groups proposed by Duke (1961). It may be related to the complex of species that form the group "Arenarioides" (Duke, 1961), sharing with it the indumentum of glandular trichomes and petals with 2—8 lobes, each with a well-developed trunk, but it differs by the absence of stipules, the laterally denticulate petal trunks, and the granular or smooth seeds. It is morphologically close to Drymaria axillaris Brandegee but differs in having petals with four lobes and in the shape and surface of its seeds. It might also be compared with D. barkleyi Duke & Steyerm., because both taxa have petals with a wide trunk (slightly wider at the base and subhastate in D. jenniferae), a short claw, and lacrimiform, tuberculate seeds. The species in the group "Arenarioides" have deltoid stipules, while the new species seemingly lacks stipules. Drymaria arenarioides and D. axillaris have short glandular trichomes 0.25-0.4 mm long, with 1 or 2 septa, while D. jenniferae has trichomes 0.5-1.0 mm long, with 3—5 septa.

The four species can be separated by the following key:

1. Plants glabrous; petals 2 (or-3)-lobate, the trunks one-third as long as the lobes; inflorescences cymes D. barkleyi
1. Plants pubescent, the trichomes sometimes stipitate glandular; petals 2-4 -lobate, the
trunks as long as the lobes; inflorescences racemes or flowers axillary.
2. Leaves linear to oblong; inflorescences racemes D. arenarioides
2. Leaves ovate; flowers axillary.
3. Stipules present; petals 2-lobeted, the trunk bases not wider than apices; seeds
reticulate D. axillaris
3. Stipules absent; petals 4-lobated, the trunk bases wider than the apices, subhastate; seeds tuberculate D. jenniferae

THE FACE OF A WHITE TIGER


The face of a White Tiger, originalmente cargada por karin widemann.

White Tiger (Panthera tigris) is a tiger with a genetic condition that nearly eliminates pigment in the normally orange fur although they still have dark stripes. This occurs when a tiger inherits two copies of the recessive gene for the paler coloration: pink nose, grey-mottled skin, ice-blue eyes, and white to cream-coloured fur with black, grey, or chocolate-coloured stripes. (Another genetic condition also makes the stripes of the tiger very pale; white tigers of this type are called snow-white.)

White tigers do not constitute a separate subspecies of their own and can breed with orange ones, although all of the resulting offspring will be heterozygous for the recessive white gene, and their fur will be orange. The only exception would be if the orange parent was itself already a heterozygous tiger, which would give each cub a 50% chance of being either double-recessive white or heterozygous orange.

Compared to orange tigers without the white gene, white tigers tend to be larger both at birth and at full adult size. This may have given them an advantage in the wild despite their unusual coloration. Heterozygous orange tigers also tend to be larger than other orange tigers. Kailash Sankhala, the director of the New Delhi Zoo in the 1960s, suggested that "one of the functions of the white gene may have been to keep a size gene in the population, in case it's ever needed."

Dark-striped white individuals are well-documented in the Bengal Tiger subspecies (Panthera tigris tigris or P. t. bengalensis), may also have occurred in captive Siberian Tigers (Panthera tigris altaica), and may have been reported historically in several other subspecies. White pelage is most closely associated with the Bengal, or Indian subspecies. Currently, several hundred white tigers are in captivity worldwide with about 100 of them in India, and their numbers are on the increase. The modern population includes both pure Bengals and hybrid Bengal–Siberians, but it is unclear whether the recessive gene for white came only from Bengals, or from any of the Siberian ancestors as well.

The unusual coloration of white tigers has made them popular in zoos and entertainment that showcases exotic animals. The magicians Siegfried & Roy are famous for having bred and trained white tigers for their performances, referring to them as "royal white tigers" perhaps from the white tiger's association with the Maharaja of Rewa.

It is a myth that white tigers did not thrive in the wild, where small groups had bred white for generations. India once planned to reintroduce them to the wild. A.A. Dunbar Brander wrote in "Wild Animals In Central India" (1923): "White tigers occasionally occur. There is a regular breed of these animals in the neighborhood of Amarkantak at the junction of the Rewa state and the Mandla and Bilaspur districts. When I was last in Mandla in 1919, a white tigress and two three parts grown white cubs existed. In 1915 a male was trapped by the Rewa state and kept in confinement. An excellent description of this animal by Mr. Scott of the Indian police, has been published in Vol. XXVII, No. 47, of the Bombay Natural History Society's journal."

However, most white tigers are now bred in captivity, often by inbreeding parents and cubs to ensure the presence of the recessive gene. Such inbreeding often also leads to birth defects.

An additional genetic condition can remove most of the striping of a white tiger, making the animal almost pure white. One such specimen was exhibited at Exeter Change in England in 1820 and described by Georges Cuvier as "A white variety of Tiger is sometimes seen, with the stripes very opaque, and not to be observed except in certain angles of light.". Naturalist Richard Lydekker said that, "a white tiger, in which the fur was of a creamy tint, with the usual stripes faintly visible in certain parts, was exhibited at the old menagerie at Exeter Change about the year 1820." Hamilton Smith said, "A wholly white tiger, with the stripe-pattern visible only under reflected light, like the pattern of a white tabby cat, was exhibited in the Exeter Change Menagerie in 1820.", and John George Wood stated that, "a creamy white, with the ordinary tigerine stripes so faintly marked that they were only visible in certain lights." Edwin Henry Landseer also drew this tigress in 1824.

The modern strain of snow white tigers came from repeated brother–sister matings of Bhim and Sumita at Cincinnati zoo. The gene involved possibly came from the Siberian tiger, via their part-Siberian ancestor Tony. Continued inbreeding appears to have caused a recessive gene for stripelessness to show up. About one fourth of Bhim and Sumita's offspring were stripeless. Their striped white offspring, which have been sold to zoos around the world, may also carry the stripeless gene.

Because Tony is present in many white tiger pedigrees, the gene may also be present in other captive white tigers. As a result, stripeless whites have occurred in zoos as far afield as the Czech Republic, Spain and Mexico. Stage magicians Siegfried & Roy were the first to attempt to breed selectively for stripelessness; they own snow white Bengal tigers taken from Cincinnati Zoo (Tsumura, Mantra, Mirage and Akbar-Kabul) and Guadalajara, Mexico (Vishnu and Jahan), and a stripeless Siberian tiger called Apollo.

In 2004, a blue-eyed, stripeless white tiger was born at a wildlife refuge in Alicante, Spain. Its parents are normal orange Bengals. The cub was named Artico ("Arctic"). Stripeless white tigers were thought to be sterile until Siegfried & Roy's stripeless white tigress Sitarra, a daughter of Bhim and Sumita, gave birth. Another variation which came out of the white strains are unusually light orange tigers called golden tabby tigers. These may be orange tigers which carry the stripeless white gene as a recessive. Some white tigers in India have been very dark nearly reverting to the orange colour.

WHALE SHARK


Whale Shark, originalmente cargada por karin widemann.

The whale shark, Rhincodon typus, is a slow filter feeding shark that is the largest living fish species. This distinctively-marked shark is the only member of its genus Rhincodon and its family, Rhincodontidae (called Rhinodontes before 1984), which is grouped into the subclass Elasmobranchii in the class Chondrichthyes. The shark is found in tropical and warm oceans and lives in the open sea. The species is believed to have originated about 60 million years ago.

The whale shark inhabits the world's tropical and warm-temperate oceans. While thought to be primarily pelagic, seasonal feeding aggregations of the sharks occur at several coastal sites such as Ningaloo Reef in Western Australia; Útila in Honduras; Donsol and Batangas in the Philippines; off Isla Mujeres and Isla Holbox in Yucatan Mexico; and the Tanzanian islands of Pemba and Zanzibar. Though it is often seen offshore, it has also been found closer to shore, entering lagoons or coral atolls, and near the mouths of estuaries and rivers. Its range is restricted to about ±30 ° latitude. It is found to a depth of 700 metres (2,300 ft). The whale shark is solitary and rarely seen in groups unless feeding at locations with an abundance of food. Males range over longer distances than females (which appear to favor specific locations).
