Plethodon Richmondi
The ravine salamander (''Plethodon richmondi)'' is a species of salamander in the family Plethodontidae. The species is endemic to the United States, and it is threatened by habitat loss. Etymology The epithet, ''richmondi'', is in honor of its discoverer, Neil D. Richmond, who later succeeded M. Graham Netting as Curator of the Section of Amphibians and Reptiles at the Carnegie Museum of Natural History, Pittsburgh, Pennsylvania. Description An adult ravine salamander is 7.5–11.5 cm (3–4½ inches) in total length (including tail). It has short limbs and is somewhat worm-like in appearance and movement. Dorsally and laterally, it is dark brown or black, with silvery or brassy flecks. Ventrally, unlike other small plethodontids, it is dark brown or black. Geographic range The ravine salamander is found in eastern Kentucky, Ohio, southern West Virginia, western Virginia, and northwestern North Carolina, northeastern Tennessee.

Myron Budd Mittleman
Myron of Eleutherae (480–440 BC) (; , ''Myrōn'' ) was an Athenian sculpture, sculptor from the mid-5th century BC. Alongside three other Greek sculptors, Polykleitos Pheidias, and Praxiteles, Myron is considered as one of the most important sculptors of classical antiquity. He was born in Eleutherae on the borders of Boeotia and Attica, Greece, Attica. According to ''Natural History (Pliny), Natural History'', a Latin encyclopedia by Pliny the Elder (AD 23 – 79), a scholar in Ancient Rome, Ageladas of Argos was his teacher. None of his original sculptures are known to survive, but there are many later copies of his works, such as his ''Discobolus'', mostly Roman. Reputation Myron worked almost exclusively in bronze and his fame rested principally upon his representations of Sportsperson, athletes (including his iconic ''Diskobolos''), in which he made a revolution, according to commentators in Antiquity, by introducing greater boldness of pose and a more perfect rhythm, su ...

Least Concern
A least-concern species is a species that has been evaluated and categorized by the International Union for Conservation of Nature (IUCN) as not being a focus of wildlife conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the " Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15,636) in the IUCN database still use the code "LR/lc", which indicates they have not been re- ...

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partners ...

Aestivation
Aestivation ( (summer); also spelled estivation in American English) is a state of animal dormancy, similar to hibernation, although taking place in the summer rather than the winter. Aestivation is characterized by inactivity and a lowered metabolic rate, that is entered in response to high temperatures and arid conditions. It takes place during times of heat and dryness, which are often the summer months. Invertebrate and vertebrate animals are known to enter this state to avoid damage from high temperatures and the risk of desiccation. Both terrestrial and aquatic animals undergo aestivation. Fossil records suggest that aestivation may have evolved several hundred million years ago. Physiology Organisms that aestivate appear to be in a fairly "light" state of dormancy, as their physiological state can be rapidly reversed, and the organism can quickly return to a normal state. A study done on '' Otala lactea'', a snail native to parts of Europe and Northern Africa, shows t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hibernation
Hibernation is a state of minimal activity and metabolic reduction entered by some animal species. Hibernation is a seasonal heterothermy characterized by low body-temperature, slow breathing and heart-rate, and low metabolic rate. It is most commonly used to pass through winter months – called overwintering. Although traditionally reserved for "deep" hibernators such as rodents, the term has been redefined to include animals such as bears and is now applied based on active metabolic suppression rather than any absolute decline in body temperature. Many experts believe that the processes of daily torpor and hibernation form a continuum and use similar mechanisms. The equivalent during the summer months is aestivation. Hibernation functions to conserve energy when sufficient food is not available. To achieve this energy saving, an endothermic animal decreases its metabolic rate and thereby its body temperature. Hibernation may last days, weeks, or months—depending on t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roger Conant (herpetologist)
Roger Conant (May 6, 1909 – December 19, 2003) was an American herpetologist, author, educator and conservationist. He was Director Emeritus of the Philadelphia Zoo and adjunct professor at the University of New Mexico. He wrote one of the first comprehensive field guides for North American reptiles in 1958 entitled: ''A Field Guide to Reptiles and Amphibians of Eastern and Central North America'', in the Peterson Field Guide series. Biography Born in Mamaroneck, New York, Conant lost his father when he was young. When he was a teenager he took a job at a local zoo to help his mother make ends meet, which, along with participating in the Boy Scouts of America, began his lifelong passion for reptiles. He was the first Eagle Scout in Monmouth County Council, New Jersey in 1924. He moved to Toledo, Ohio in 1929 and worked as Curator of Reptiles, and later General Curator at the Toledo Zoo from 1929 to 1935. In 1935 he returned to Philadelphia and became the Curator of Reptiles at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forest
A forest is an ecosystem characterized by a dense ecological community, community of 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 (biology), 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 (FRA), Global Forest Resources Assessment 2020'' found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the largest Terrestrial ecosystem, terrestrial ecosystems of Earth by area, and are found around the globe. 45 percent of forest land is in the Tropical forest, trop ...

Habitat
In ecology, habitat refers to the array of resources, biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species' habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as Biophysical environment, environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and Luminous intensity, light intensity. Biotic index, Biotic factors include the availability of food and the presence or absence of Predation, predators. Every species has particular habitat requirements, habitat generalist species are able to thrive in a wide array of environmental conditions while habitat specialist species require a very limited set of factors to survive. The habitat of a species is not necessarily found in a ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
