Micrurus Clarki
''Micrurus clarki'', also known commonly as Clark's coral snake, is a species of venomous snake in the family Elapidae. The species is native to Central America and northwestern South America. Etymology The specific name, ''clarki'', is in honor of Dr. Herbert Charles Clark (1877–1960), who was Director of Laboratories and Preventive Medicine for United Fruit Company, and then was Director of Gorgas Memorial Laboratory (1929–1954), in Panama.

Karl Patterson Schmidt
Karl Patterson Schmidt (June 19, 1890 – September 26, 1957) was an American herpetologist. Family Schmidt was the son of George W. Schmidt and Margaret Patterson Schmidt. George W. Schmidt was a German professor, who, at the time of Karl Schmidt's birth, was teaching in Lake Forest, Illinois. His family left the city in 1907 and settled in Wisconsin. They worked on a farm near Stanley, Wisconsin, where his mother and his younger brother died in a fire on August 7, 1935. The brother, Franklin J. W. Schmidt, had been prominent in the then-new field of wildlife management. Karl Schmidt married Margaret Wightman in 1919, and they had two sons, John and Robert. Education In 1913, Schmidt entered Cornell University to study biology and geology. In 1915, he discovered his preference for herpetology during a four-month training course at the Perdee Oil Company in Louisiana. In 1916, he received the degree of Bachelor of Arts and made his first geological expedition to Santo Do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Darién Gap
The Darién Gap (, , es, Tapón del Darién , ) is a geographic region between the North and South American continents within Central America, consisting of a large watershed, forest, and mountains in Panama's Darién Province and the northern portion of Colombia's Chocó Department. The "gap" in question is that of the Pan-American Highway, of which between Yaviza, Panama, and Turbo, Colombia, has not been built. Roadbuilding through this area is expensive and detrimental to the environment. Political consensus in favor of road construction collapsed after an initial attempt failed in the early 1970s, resuming in 1992 only to be halted by serious environmental concerns. As of 2022, there is no active plan to build the missing road. The geography of the Darién Gap on the Colombian side is dominated primarily by the river delta of the Atrato River, which creates a flat marshland at least wide. The Serranía del Baudó range extends along Colombia's Pacific coast and into P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reptiles Of Panama
Reptiles, as most commonly defined are the animals in the class Reptilia ( ), a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates (lizards and snakes) and rhynchocephalians (tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. The earliest known proto-reptiles originated around 31 ...

Snakes Of North America
Snakes are elongated, limbless, carnivorous reptiles of the suborder Serpentes . Like all other squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales. Many species of snakes have skulls with several more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads (cranial kinesis). To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most have only one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have evolved elongate bodies without limbs or with greatly reduced limbs about twenty-five times independently via convergent evolution, leading to many lineages of legless lizards. These resemble snakes, but several common groups of legless lizards have eyelids and external ears, which snakes lack, although this rule is not universal (see Amphisbaenia, Dibamida ...

Jay M
A jay is a member of a number of species of medium-sized, usually colorful and noisy, passerine birds in the Crow family, Corvidae. The evolutionary relationships between the jays and the magpies are rather complex. For example, the Eurasian magpie seems more closely related to the Eurasian jay than to the East Asian blue and green magpies, whereas the blue jay is not closely related to either. Systematics and species Jays are not a monophyletic group. Anatomical and molecular evidence indicates they can be divided into an American and an Old World lineage (the latter including the ground jays and the piapiac), while the grey jays of the genus ''Perisoreus'' form a group of their own.http://www.nrm.se/download/18.4e32c81078a8d9249800021299/Corvidae%5B1%5D.pdf PDF fulltext The black magpies, formerly believed to be related to jays, are classified as treepies.

Oviparity
Oviparous animals are animals that lay their eggs, with little or no other embryonic development within the mother. This is the reproductive method of most fish, amphibians, most reptiles, and all pterosaurs, dinosaurs (including birds), and monotremes. In traditional usage, most insects (one being ''Culex pipiens'', or the common house mosquito), molluscs, and arachnids are also described as oviparous. Modes of reproduction The traditional modes of reproduction include oviparity, taken to be the ancestral condition, traditionally where either unfertilised oocytes or fertilised eggs are spawned, and viviparity traditionally including any mechanism where young are born live, or where the development of the young is supported by either parent in or on any part of their body. However, the biologist Thierry Lodé recently divided the traditional category of oviparous reproduction into two modes that he named ovuliparity and (true) oviparity respectively. He distinguished the tw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fossorial
A fossorial () animal is one adapted to digging which lives primarily, but not solely, underground. Some examples are badgers, naked mole-rats, clams, meerkats, and mole salamanders, as well as many beetles, wasps, and bees. Prehistoric evidence The physical adaptation of fossoriality is widely accepted as being widespread among many prehistoric phyla and taxa, such as bacteria and early eukaryotes. Furthermore, fossoriality has evolved independently multiple times, even within a single family. Fossorial animals appeared simultaneously with the colonization of land by arthropods in the late Ordovician period (over 440 million years ago). Other notable early burrowers include ''Eocaecilia'' and possibly ''Dinilysia''. The oldest example of burrowing in synapsids, the lineage which includes modern mammals and their ancestors, is a cynodont, ''Thrinaxodon liorhinus'', found in the Karoo of South Africa, estimated to be 251 million years old. Evidence shows that this ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forest
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in th ...
