Otters
Otters are carnivorous mammals in the Rank (zoology), subfamily Lutrinae. The 13 extant otter species are all semiaquatic, aquatic animal, aquatic, or Marine ecology, marine. Lutrinae is a branch of the Mustelidae Family (biology), family, which includes weasels, badgers, mink, and wolverines, among other animals. Otters' habitats include dens known as holts or couches, with their social structure described by terms such as dogs or boars for males, bitches or sows for females, and pups or cubs for offspring. Groups of otters can be referred to as a bevy, family, lodge, romp, or raft when in water, indicating their social and playful characteristics. Otters are known for their distinct feces, termed spraints, which can vary in smell from freshly mown hay to putrefied fish. Otters exhibit a varied life cycle with a gestation period of about 60–86 days, and offspring typically stay with their family for a year. They can live up to 16 years, with their diet mainly consisting of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Giant Otter
The giant otter or giant river otter (''Pteronura brasiliensis'') is a South American carnivorous mammal. It is the longest member of the weasel family, Mustelidae, a globally successful group of predators, reaching up to . Atypical of mustelids, the giant otter is a social species, with family groups typically supporting three to eight members. The groups are centered on a dominant breeding pair and are extremely cohesive and cooperative. Although generally peaceful, the species is territorial, and aggression has been observed between groups. The giant otter is diurnal, being active exclusively during daylight hours. It is the noisiest otter species, and distinct vocalizations have been documented that indicate alarm, aggression, and reassurance. The giant otter ranges across north-central South America; it lives mostly in and along the Amazon River and in the Pantanal. Its distribution has been greatly reduced and is now discontinuous. Decades of poaching for its velvety ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pliocene
The Pliocene ( ; also Pleiocene) is the epoch (geology), epoch in the geologic time scale that extends from 5.33 to 2.58See the 2014 version of the ICS geologic time scale million years ago (Ma). It is the second and most recent epoch of the Neogene Period in the Cenozoic, Cenozoic Era. The Pliocene follows the Miocene Epoch and is followed by the Pleistocene Epoch. Prior to the 2009 revision of the geologic time scale, which placed the four most recent major glaciations entirely within the Pleistocene, the Pliocene also included the Gelasian Stage, which lasted from 2.59 to 1.81 Ma, and is now included in the Pleistocene. As with other older geologic periods, the Stratum, geological strata that define the start and end are well-identified but the exact dates of the start a ...

Pleistocene
The Pleistocene ( ; referred to colloquially as the ''ice age, Ice Age'') is the geological epoch (geology), epoch that lasted from to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek () 'most' and (; Latinized as ) 'new'. The aridification and cooling trends of the preceding Neogene were continued in the Pleistocene. The climate was strongly variable depending on the glacial cycle, oscillating between cold Glacial period, glacial periods and warmer Interglacial, int ...

John Alroy
John Alroy is a paleobiologist born in New York in 1966 and now residing in Sydney, Australia. Area of expertise Alroy specializes in diversity curves, speciation, and extinction of North American fossil mammals and Phanerozoic marine invertebrates, connecting regional and local diversity, taxonomic composition, body mass distributions, ecomorphology, and phylogenetic patterns to intrinsic diversity dynamics, evolutionary trends, mass extinctions, and the effects of global climate change. In a 3 September 2010 online article by Hugh Collins, a contributor for AOL Online Science, Alroy was quoted in a newly released study paper from Sydney's Macquarie University that "It would be unwise to assume that any large number of species can be lost today without forever altering the basic biological character of Earth's oceans." Education He graduated from Hunter College High School in 1984. He then received his BA from Reed College, Department of Biology, in 1989. And then his PHD ...

History Prior to the arrival of the Spanish, what is now DeSoto County was within the territory of the Native American Calusa tribe. In 1513, Ponce De Leon sailed into present-day Charlotte Harbor near the mouth of the Peace River to put in for repairs and maintenance on his ships. While there the Spanish encountered Calusa and soon after an argument broke out and several died on both sides. Then the Spanish kidnapped several Calusa and departed Charlotte Harbor and sailed S.W. away from the west coast of Florida. This occurred within ...

Joseph Leidy
Joseph Mellick Leidy (September 9, 1823 – April 30, 1891) was an American paleontologist, parasitologist and anatomist. Leidy was professor of anatomy at the University of Pennsylvania, later becoming a professor of natural history at Swarthmore College and the director of scientific and educational programs at the Wagner Free Institute of Science. His book ''Extinct Fauna of Dakota and Nebraska'' (1869) contained many species not previously described and many previously unknown on the North American continent. At the time, scientific investigation was largely the province of wealthy amateurs. The Leidy Glacier in northwest Greenland was named by Robert Peary after him. Early life and family Joseph Leidy was born on September 9, 1823, to an established Philadelphia family of Pennsylvania Germans. His father, Philip, was a hatter; his mother, Catharine, died during childbirth when he was young. His father then married his wife's first cousin, Christiana Mellick. Leidy al ...
