Black-bellied Slender Salamander
The black-bellied slender salamander (''Batrachoseps nigriventris'') is a small species of salamander that is endemic to California. Distribution This salamander prefers California chaparral and woodlands habitats of Coast live oak - ''Quercus agrifolia'' and California sycamore - ''Platanus racemosa''. Description The black-bellied slender salamander is about 3.1 to 4.3 cm long. It has a worm-like body, a small head and small limbs, and a long cylindrical tail, often twice the length of its body. The black-bellied slender salamander can have a black, tan, reddish, brown or beige dorsum often with a contrasting broad mid-dorsal stripe of similar colors. It has a purplish or black venter with fine light speckling over the entire surface. This species will coil its body and tail when handled; it is fragile and easily injured. ''Batrachoseps nigriventis'' looks similar to the related species ''Batrachoseps pacificus The Channel Islands slender salamander (''Batrachose ...

Salamander
Salamanders are a group of amphibians typically characterized by their lizard-like appearance, with slender bodies, blunt snouts, short limbs projecting at right angles to the body, and the presence of a tail in both larvae and adults. All ten extant salamander families are grouped together under the order Urodela. Salamander diversity is highest in eastern North America, especially in the Appalachian Mountains; most species are found in the Holarctic realm, with some species present in the Neotropical realm. Salamanders rarely have more than four toes on their front legs and five on their rear legs, but some species have fewer digits and others lack hind limbs. Their permeable skin usually makes them reliant on habitats in or near water or other cool, damp places. Some salamander species are fully aquatic throughout their lives, some take to the water intermittently, and others are entirely terrestrial as adults. This group of amphibians is capable of regenerating lost lim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Habitat
In ecology, the term habitat summarises the array of resources, physical and 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 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 light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quercus Agrifolia
''Quercus agrifolia'', the California live oak, or coast live oak, is a highly variable, often evergreen oak tree, a type of live oak, native to the California Floristic Province. It may be shrubby, depending on age and growing location, but is generally a medium-sized tree. It grows west of the Sierra Nevada mountain range from Mendocino County, California, south to northern Baja California in Mexico. It is classified in the red oak section of oaks (''Quercus'' sect. ''Lobatae''). This species is commonly sympatric with canyon live oak (''Q. chrysolepis''), and the two may be hard to distinguish because their spinose leaves are superficially similar. Description Coast live oak typically has a much-branched trunk and reaches a mature height of . Some specimens may attain an age exceeding 1,000 years. Examples of this include the Grand Oak of Cherry Valley, California, the Encino Oak Tree, which died in the 1990s (part of the stump has been preserved) and the Pechanga Gre ...

Platanus Racemosa
''Platanus racemosa'' is a species of plane tree known by several common names, including California sycamore, western sycamore, California plane tree, and in North American Spanish aliso. ''Platanus racemosa'' is native to California and Baja California, where it grows in riparian areas, canyons, floodplains, at springs and seeps, and along streams and rivers in several types of habitats.Santa Monica Mountains National Recreation Area (N.R.A.), General Management Plan (GMP): Environmental Impact Statement. United States: n.p., 1982. It can be found as far north as Tehama and Humboldt counties. Description This large tree grows to in height with a trunk diameter of up to one meter (three feet). A specimen on the campus of Stanford University has a trunk girth (circumference) of . The trunk generally divides into two or more large trunks splitting into many branches. The bark is an attractive patchwork of white, tawny beige, pinkish gray, and pale brown, with older bark beco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

It has a black dorsum with white, coppery, and orange blotches, and an immaculate black venter. It may have red spots on tail. ''B. gabrieli'' is similar to the related species '' B. pacificus'' and '' B. nigriventis''.

Batrachoseps
''Batrachoseps'' is a genus of lungless salamanders (plethodontids) often called slender salamanders. They can be distinguished from other lungless salamanders by the four toes they have on each foot. Their genus name ''Batracho-seps'' means "frog-lizard", in reference to their projectile tongues. Diet and physiology The lungless salamanders, in addition to having no lungs, have long slender snake-shaped bodies with very small limbs that appear almost vestigial in several species. Their main diet consists of small insects, such as springtails, small bark beetles, crickets, young snails, mites, and spiders. Like all salamanders in this family, they have long frog-like projectile tongues which they use to grab their prey in a flash. Unlike all other amphibians (and birds, and lizards, and nearly all fish) mature red blood cells in species in the genus ''Batrachoseps'' have no nucleus, which is a trait that is only known to occur in mammals and certain species of antarctic fish. ...

Amphibians Of The United States
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic decline ...
