Aimophila Aestivalis
Bachman's sparrow (''Peucaea aestivalis''), also known as the pinewoods sparrow or oakwoods sparrow, is a small American sparrow that is endemic to the southeastern United States. This species was named in honor of Reverend John Bachman. Adults have rufous brown upperparts and crown with gray and black streaking on the nape, back and primaries. The face is gray with a rufous brown eyestripe. It has a buff colored breast and whitish belly. These are mid-sized New World sparrows, measuring and weighing . Their breeding habitat is open pine forests. The domed nest is usually built on the ground near a clump of grass or a bush. Females lay three to five eggs. Bachman's sparrow is primarily a non-migratory resident, but it may retreat from some of the most northerly territories. The species is mainly a granivore, but it will also take some insects. This bird is considered near threatened by the IUCN, with habitat loss one of the major factors often cited in its decline. Habitat deg ...

Hinrich Lichtenstein
Martin Hinrich Carl Lichtenstein (10 January 1780 – 2 September 1857) was a German physician, explorer, botanist and zoologist. Biography Born in Hamburg, Lichtenstein was the son of Anton August Heinrich Lichtenstein. He studied medicine at Jena and Helmstedt. Between 1802 and 1806 he travelled in southern Africa, becoming the personal physician of the Governor of the Cape of Good Hope. In 1811 he published ''Reisen im südlichen Afrika : in den Jahren 1803, 1804, 1805, und 1806''; as a result, he was appointed professor of zoology at the University of Berlin in 1811, and appointed director of the Berlin Zoological Museum in 1813. In 1829, he was elected a foreign member of the Royal Swedish Academy of Sciences. He died after he had a stroke at sea travelling aboard a steamer from Korsør to Kiel. Legacy Lichtenstein was responsible for the creation of Berlin's Zoological Gardens in 1841, when he persuaded King Frederick William IV of Prussia to donate the grounds of ...

Longleaf Pine
The longleaf pine (''Pinus palustris'') is a pine species native to the Southeastern United States, found along the coastal plain from East Texas to southern Virginia, extending into northern and central Florida. In this area it is also known as "yellow pine" or "long leaf yellow pine", although it is properly just one out of a number of species termed yellow pine. It reaches a height of and a diameter of . In the past, before extensive logging, they reportedly grew to with a diameter of . The tree is a cultural symbol of the Southern United States, being the official state tree of Alabama. Contrary to popular belief, this particular species of pine is not officially the state tree of North Carolina. Description The bark is thick, reddish-brown, and scaly. The leaves are dark green and needle-like, and occur in bundles of mainly three, sometimes two or four, especially in seedlings. They often are twisted and in length.

Peucaea
''Peucaea'' is a genus of American sparrows. The species in this genus used to be included in the genus '' Aimophila''. Taxonomy and species A molecular phylogenetic study published in 2009 found that the genus '' Aimophila'' was polyphyletic. In the resulting reorganization to create monophyletic genera, eight species were moved from '' Aimophila'' to the resurrected genus ''Peucaea''. ''Peucaea'' had been introduced by the Franco-American ornithologist John James Audubon in 1839. The genus name is from the Ancient Greek ''peukē'' meaning "pine-tree". The type species was designated by English zoologist George Robert Gray in 1841 as ''Fringilla bachmani'', a taxon now considered to be a subspecies of Bachman's sparrow with the trinomial name ''Peucaea aestivalis bachmani''. ''Peucaea'' is the sister genus to ''Ammodramus'' within the family Passerellidae. The genus contains the following 8 species: * Rufous-winged sparrow, ''Peucaea carpalis'' * Cinnamon-tailed sparrow, ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coarse Woody Debris
Coarse woody debris (CWD) or coarse woody habitat (CWH) refers to fallen dead trees and the remains of large branches on the ground in forests and in rivers or wetlands.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservation (2nd edition). Cambridge University Press, Cambridge, UK. 497 p, p. 225-227. A dead standing tree – known as a snag – provides many of the same functions as coarse woody debris. The minimum size required for woody debris to be defined as "coarse" varies by author, ranging from in diameter. Since the 1970s, forest managers worldwide have been encouraged to allow dead trees and woody debris to remain in woodlands, recycling nutrients trapped in the wood and providing food and habitat for a wide range of organisms, thereby improving biodiversity. The amount of coarse woody debris is considered an important criterion for the evaluation and restoration of temperate deciduous forest. Coarse woody debris is also important in wetlands, particularly in riv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herbaceous Layer
Stratification in the field of ecology refers to the vertical layering of a habitat; the arrangement of vegetation in layers. It classifies the layers (sing. ''stratum'', pl. ''strata'') of vegetation largely according to the different heights to which their plants grow. The individual layers are inhabited by different animal and plant communities (stratozones). Vertical structure in terrestrial plant habitats The following layers are generally distinguished: forest floor (root and moss layers), herb, shrub, understory and canopy layers. These vegetation layers are primarily determined by the height of their individual plants, the different elements may however have a range of heights. The actual layer is characterised by the height range in which the vast majority of photosynthetic organs (predominantly leaves) are found. Taller species will have part of their shoot system in the underlying layers. In addition to the above-ground stratification there is also a “root layer”. ...

Goose Bumps
Goose bumps, goosebumps or goose-pimples are the bumps on a person's skin at the base of body hairs which may involuntarily develop when a person is tickled, cold or experiencing strong emotions such as fear, euphoria or sexual arousal. The formation of goose bumps in humans under stress is considered to be a vestigial reflex. Its function in other apes is to raise the body's hair, and would have made human ancestors appear larger to scare off predators or to increase the amount of air trapped in the fur to make it more insulating. The reflex of producing goose bumps is known as piloerection or the pilomotor reflex, or, more traditionally, horripilation. It occurs in many mammals; a prominent example is porcupines, which raise their quills when threatened, or sea otters when they encounter sharks or other predators. Anatomy and biology Goose bumps are created when tiny muscles at the base of each hair, known as ''arrector pili muscles'', contract and pull the hair straight u ...

Agkistrodon Piscivorus
''Agkistrodon piscivorus'' is a species of pit viper in the subfamily Crotalinae of the family Viperidae. It is one of the world's few semiaquatic vipers (along with the Florida cottonmouth), and is native to the southeastern United States. As an adult, it is large and capable of delivering a painful and potentially fatal bite. When threatened, it may respond by coiling its body and displaying its fangs. Individuals may bite when feeling threatened or being handled in any way. It tends to be found in or near water, particularly in slow-moving and shallow lakes, streams, and marshes. It is a capable swimmer and, like several species of snakes, is known to occasionally enter bays and estuaries and swim between barrier islands and the mainland. Gloyd HK, Conant R (1990). ''Snakes of the ''Agkistrodon'' Complex: A Monographic Review''. Society for the Study of Amphibians and Reptiles. 614 pp. 52 plates. LCCN 89-50342. .

Distraction Display
Distraction displays, also known as diversionary displays, or paratrepsis are anti-predator behaviors used to attract the attention of an enemy away from something, typically the nest or young, that is being protected by a parent. Distraction displays are sometimes classified more generically under "nest protection behaviors" along with aggressive displays such as mobbing. These displays have been studied most extensively in bird species, but also have been documented in populations of stickleback fishRuxton, Graeme D; Thomas N. Sherratt; Michael Patrick Speed. (2004) Avoiding attack: the evolutionary ecology of crypsis, warning signals and mimicry. Oxford University Press. . p. 198 and in some mammal species. Distraction displays frequently take the form of injury-feigning. However, animals may also imitate the behavior of a small rodent or alternative prey item for the predator; imitate young or nesting behaviors such as brooding (to cause confusion as to the true location of th ...

Avian Clutch Size
Clutch size refers to the number of eggs laid in a single brood by a nesting pair of birds. The numbers laid by a particular species in a given location are usually well defined by evolutionary trade-offs with many factors involved, including resource availability and energetic constraints. Several patterns of variation have been noted and the relationship between latitude and clutch size has been a topic of interest in avian reproduction and evolution. David Lack and R.E. Moreau were among the first to investigate the effect of latitude on the number of eggs per nest. Since Lack's first paper in the mid-1940s there has been extensive research on the pattern of increasing clutch size with increasing latitude. The proximate and ultimate causes for this pattern have been a subject of intense debate involving the development of ideas on group, individual, and gene-centric views of selection. Food limitation and nest predation hypotheses David Lack observed a direct relationship ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
