Showing 17 Information results for Ambystoma mexicanum

Ambystoma mexicanum is historically found in Lakes Chalco and Xochimilco of the Valley of Mexico near Mexico City, Mexico. The native habitats of A. mexicanum are large, relatively permanent (until recently), high-altitude lakes located near Mexico City. Of the two lakes - Chalco and Xochimilco - where these animals are historically native, only Xochimilco (elevation: ~ 2,274 m) remains. Axolotls are almost extinct in their native habitat, largely due to the introduction of predatory fishes and habitat loss

Ambystoma

eat insects and other small invertebrates (Wilbur, 1972). Ambystoma do not directly impact the economy. They are, however, ecologically important as an indicator of environmental health and a contributor to pest control (Davic & Welsh, 2004). They are also becoming more popular as pets, specifically the Mexican axolotl (Ambystoma mexicanum) (Voss et al., 2015). There are no known adverse effects of Ambystoma on humans. Due to habitat disturbance, many Ambystoma species are becoming increasingly threatened

Ambystoma californiense California Tiger Salamander

invaded pools constructed for cattle. There is no current information on the reproductive behavior of Ambystoma californiense. However, it’s sister species, Ambystoma triginum reproductive behavior is highly characterized. Ambystoma triginum males have a preference for females who are larger because they often produce larger clutches. Female sexual selection are currently under investigation. Initiating copulation is an aggressive process in Ambystoma tigrinum, which is initiated with the male shoving the

Ambystoma mavortium Barred Tiger Salamander; Western Tiger Salamander

salamanders. Their other basic appearances do not change. Nothing is published on the reproductive mating systems of this species. However, as a former subspecies of tiger salamanders (Ambystoma tingrinum), it is likely that Ambystoma mavoritum has similar reproductive behaviors.Males move to a pond after hibernation to prepare for the emergence of females. Breeding occurs in ponds at night. Nocturnal mating limits exposure to their natural predators. A male will nudge multiple females until one gives him

Ambystoma cingulatum Flatwoods Salamander; Frosted Flatwoods Salamander

Flatwoods salamanders, Ambystoma cingulatum, inhabit the southern Atlantic coast of the United States ranging from the middle of South Carolina to the panhandle of Florida. They span as far west as the Apalachicola-Flint Rivers in northern Florida, but not crossing the Appalachians in South Carolina or Georgia. Flatwoods salamander individuals may travel up to 1700 meters within their geographic range to breed in the winter, but otherwise will never stray more than a couple meters from their underground

Ambystoma opacum Marbled Salamander

Ambystoma opacum, the marbled salamander is found throughout most of the eastern United States, from Massachusetts west to central Illinois, southeastern Missouri and Oklahoma and eastern Texas, south to the Gulf of Mexico and the Carolina coast. It is absent from peninsular Florida. Disjunct populations are found in eastern Missouri, central Illinois, in northwest Ohio/northeast Indiana, and along the southern edges of Lake Michigan and Lake Erie. Adult marbled salamanders live in damp woodlands, often

Ambystoma tigrinum Eastern Tiger Salamander; Tiger Salamander

tiger salamanders remain in the aquatic larval form for their entire lives. Ambystoma tigrinum migrates to the breeding ponds in late winter or early spring, usually after a warm rain that thaws out the ground's surface. Males tend to arrive earlier than the females, probably due to the fact that they live closer to the ponds during the winter months. Courtship happens during the night where the males nudge and bump other salamanders. Upon coming across a female, the male will nudge her with his snout to

Ambystoma macrodactylum croceum Santa Cruz Long-toed Salamander

terrestrial adults, the salamanders live in isolated populations in upland and mixed forests and estivate in aquatic habitats. They favor living conditions that allow their skin to stay moist and cool, and residing under forest litter does just this.(Larson 1997) Ambystoma macrodactylum croceum is a small salamander, reaching a full-grown adult length of approximately 127 mm, (5 inches). The body of an adult is a glossy black-charcoal color, with brilliant yellow and orange spots covering its back

Ambystoma talpoideum Mole Salamander

insects, tadpoles, earthworms, athropods, and an assortment of other invertebrates. Mole salamanders are subject to predation from other salamanders as well as other aquatic predators. Larval salamander communities are highly structured by predation. Mole salamanders tend to breed later than other species of Ambystoma and are subject to more competition and predation as a result. Marbled salamanders (Ambystoma opacuum) breed earlier and their larvae feed on mole salamander eggs and larvae. Bluegill sunfish

Ambystoma annulatum Ringed Salamander

Ambystoma annulatum has been mostly found in the vicinity of Hot Springs Arkansas and throughout most of the forested Ozark Plateau in Missouri (Bishop 1962, Johnson 1977). Small populations of ringed salamanders have been found in south western Illinois and eastern Oklahoma as well (Petranka 1998). Ambystoma annulatum prefers damp hardwood forests that are near shallow ponds (Bishop 1962). These salamanders are usually found hidden under rocks and logs, in piles of dead leaves, or burrowing in the soil

Ambystoma gracile Northwestern Salamander

severely weaken the salamander population in the surrounding area. Limb regeneration is a phenomenon that occurs in this species. Tissue in the remnants of the limb regenerate nerve fibers, and the new limb bud slowly emerges and forms.Ambystoma gracile is commonly referred to as the northwestern salamander, or is divided into two subspecies, the brown salamander, Ambystoma gracile gracile (found in the southern portion of the range), and the British Columbia salamander, Ambystoma gracile decorticatum

Ambystoma maculatum Spotted Salamander

diversity of other species in the pools, especially other amphibians. Gray treefrogs (Hyla chrysoscelis and Hyla versicolor) avoid breeding in ponds with spotted salamanders in them, and depending on the timing and size of the other species present, spotted salamanders may reduce the population of other Ambystoma species in their pools. Spotted salamanders may help control insect pest species, including mosquitoes that breed in their ponds. There are no known adverse effects of Ambystoma maculatum on humans

Ambystoma laterale Blue-spotted Salamander

Ambystomatidae Mole Salamanders

Ambystoma barbouri Streamside Salamander

Ambystoma barbouri (streamside salamanders) are native throughout central Kentucky, with their range extending up into some parts of southwestern Ohio and sparingly in southeastern Indiana (Kraus and Petranka, 1989). A small population was recorded in the northwestern corner of West Virginia (Green, 1955). Most recently, populations were discovered in the Central Basin of middle Tennessee (Scott et al. 1997). Streamside salamanders occupy upland deciduous forest in areas of varying latitude (Kraus and

Ambystoma jeffersonianum Jefferson Salamander

females. These females are thought to reproduce gynogenetically, they use sperm from a sympatric, diploid male to initiate the development of the eggs without incorporating the male genome. Some females, however, do reproduce through hybridogenesis, where the maturing egg eliminates an entire genome. The embryonic mortality rates of salamanders in hybrid complexes is much higher than that of diploid salamander species. Studies have found that temperature is of great importance in the hybrid Ambystoma. At

Ambystoma texanum Small-mouthed Salamander

there are breeding ponds free of fish. Small-mouthed salamanders are more versatile in their breeding requirements than other Ambystoma. They can breed in woodland vernal ponds, runoff ponds, flooded areas, river backwaters, and roadside ditches. Ambystoma texanum does not travel far from breeding ponds, so good habitat near the pond is important. As its name suggests this species has a relatively small head with a blunt, short snout. The head tends to appear swollen behind the eyes and the lower jaw barely
