In recent years, Steller sea lions have been known to enter the Columbia River estuary and feed on white sturgeon, several salmon species and rainbow trout, some of which are also listed under the U. S. Endangered Species Act.

As a consequence, in 1997 the western stock of Steller sea lions was listed as endangered and the eastern stock was listed as threatened under the Endangered Species Act.

In contemporary literature, the Steller's sea cow appears in a book of poetry, Species Evanescens, by Russian poet Andrei Bronnikov.

The Convention on Migratory Species works for the conservation of loggerhead sea turtles on the Atlantic coast of Africa, as well as in the Indian Ocean and southeast Asia.

Species can be recognized by their rosettes of more or less folded leaves with persistent bases and quite prominent nonglandular hairs.

Although it has previously been assigned to its own genus Alopex, genetic evidence places it in Vulpes ( Mammal Species of the World ) with the majority of the other foxes.

Charles Darwin proposed the theory of universal common descent through an evolutionary process in On the Origin of Species, twice stating the hypothesis that there was only one progenitor for all life forms and ending with " There is a grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one ".

Darwin did not use the term in Origin of Species until its sixth edition in 1872, ( though earlier editions did use the word " evolved ") by which time Herbert Spencer had given it scientific currency with a broad definition of progression in complexity in 1862.

The National Environmental Policy Act ( 1969 ), the Clean Air Act ( 1970 ), the Clean Water Act ( 1972 ), and the Endangered Species Act ( 1973 ) all were enacted with broad bipartisan support, and ultimately signed into law by Republican President Richard Nixon.

The possibility of linking humans with earlier apes by descent only became clear after 1859 with the publication of Charles Darwin's On the Origin of Species.

Species of identical particles include elementary particles such as electrons, and, with some clauses, composite particles such as atoms and molecules.

Studies of Charles Darwin's notebooks have shown that Darwin arrived separately at the idea of natural selection which he set out in his 1859 book On the Origin of Species, but it has been speculated that he may have had some half-forgotten memory from his time as a student in Edinburgh of ideas of selection in nature as set out by Hutton, and by William Charles Wells and Patrick Matthew who had both been associated with the city before publishing their ideas on the topic early in the 19th century.

Along with dwelling in a sukkah, the principal ritual unique to this holiday is use of the Four Species ( lulav ( palm ), hadass ( myrtle ), aravah ( willow ) and etrog ( citron ).

Species can be placed in a ranked hierarchy, starting with either domains or kingdoms.

The term was introduced by Darwin in his groundbreaking 1859 book On the Origin of Species, in which natural selection was described by analogy to artificial selection, a process by which animals and plants with traits considered desirable by human breeders are systematically favored for reproduction.

In the fourth edition ( 1866 ) of On the Origin of Species Darwin wrote that " the periods during which species have undergone modification, though long as measured in years, have probably been short in comparison with the periods during which they retain the same form.

In cooperation with the International Red Panda Management Group, they coordinate the Species Survival Plan in North America, the European Endangered Species Programme in Europe and other captive-breeding programs in Australia, India, Japan and China.

Species which have adapted to these different conditions are described as specialized to successfully exploit narrow vertical zones on the rocky shore.

The ship on which Charles Darwin made the voyage which provided much of the inspiration for On the Origin of Species was named HMS Beagle after the breed, and, in turn, lent its name to the ill-fated British Martian lander Beagle 2.

Species are proposed for inclusion in or deletion from the Appendices at meetings of the Conference of the Parties ( CoP ), which are held approximately once every three years, the most recent of which ( CoP 15 ) was held in Qatar in March 2010.

Species in the Appendices may be proposed for addition, change of Appendix, or de-listing ( i. e., deletion ) by any Party, whether or not it is a range State and changes may be made despite objections by range States if there is sufficient ( 2 / 3 majority ) support for the listing.

While Charles Darwin is mainly noted for his treatise on evolution, he was one of the founders of soil ecology, and he made note of the first ecological experiment in The Origin of Species.

When Darwin wrote On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life, the oldest animal fossils were those from the Cambrian Period, now known to be about 540 million years old.

The list follows McKenna and Bell's Classification of Mammals for prehistoric genera ( 1997 ) and Wozencraft ( 2005 ) in Wilson and Reeder's Mammal Species of the World for extant genera.

Gray whales are protected under Canada's Species at Risk Act which obligates Canadian governments to prepare management plans for the whales and consider the interests of the whales when permitting development.

In an often misquoted passage from On the Origin of Species, Charles Darwin appears to acknowledge the eye's development as a difficulty for his theory.

Two of his works, the first edition of the Species Plantarum ( 1753 ) for plants and the tenth edition of the Systema Naturae ( 1758 ), are accepted as among the starting points of nomenclature ; his binomials ( names for species ) and his generic names take priority over those of others.

Species for which the reserve is important include Pale-bellied Brent Goose, Wigeon, Teal, Pintail, Merlin, Dunlin, Bar-tailed Godwit and many others.
