    local tiger salamander population (Ambystoma tigrinum), and a dramatic loss to its population abundance and distribution (McMenamin et al. ). This environmental stress is manifest in changes in life history traits such as body size, developmental timing, and feeding habits, all of. The long-toed salamander (Ambystoma macrodactylum) is a mole salamander in the family Ambystomatidae. This species, typically – cm (– in) long when mature, is characterized by its mottled black, brown, and yellow pigmentation, and its long outer fourth toe on the hind limbs.

Ullman.   Expressed sequence tag (EST) markers were developed for Ambystoma tigrinum tigrinum (Eastern tiger salamander) and for A. mexicanum (Mexican axolotl) to generate the first comprehensive linkage map for these model amphibians. We identified 14 large linkage groups (– cM) that presumably correspond to the 14 haploid chromosomes in the Ambystoma .

THE tiger salamander (Ambystoma tigrinum) species complex consists of several closely related and phenotypically diverse taxa that range from central Mexico to southern Canada (S haffer and M c K night ).The complex as a whole is an important, naturalistic model system because taxa are characterized by extensive interspecific and intraspecific variation for a number of ecologically Cited by:   Ambystoma tigrinum exhibits phenotypic plasticity with metamorph and paedomorph adults.

McCarthy, Dorothy Wallace, Howard H. Whiteman, Evan T. Rheingold, Ann M. Dunham, Olivia Pro. We examined diet-dependent plasticity in head shape in larvae of the eastern long-toed salamander, Ambystoma macrodactylum columbianum.

Larvae in some populations of this species exhibit trophic polymorphism, with some individuals possessing exaggerated trophic features characteristic of a cannibalistic morphology in larval Ambystoma; e.g.

a disproportionately broad head and. Abstract. The tiger salamander, Ambystoma tigrinum, is a geographically widespread, morphologically variable, polytipic is among the most variable species of salamanders in morphology and life history with two larval morphs (typical and cannibal) and three adult morphs (metamorphosed, typical branchiate, cannibal branchiate) that vary in frequency between subspecies and between.

In playas of the Southern Great Plains, larval barred tiger salamanders (Ambystoma tigrinum mavortium Baird, ) (= Ambystoma mavortium mavortium) are present as polymorphic l and cannibal morphs have been previously investigated but intermediate forms have received little attention and their role in playa food web structure is unknown.

The Ambystoma tigrinum Virus (ATV), isolated from populations of the Sonoran Tiger Salamander (A. mavortium stebbinsi) in Arizona, periodically causes mass mortality in populations of this subspecies (Jancovich et al. ) and has been implicated in several die-offs of Western Tiger Salamanders in Saskatchewan and Manitoba, as well as several.

The iridovirus Ambystoma tigrinum Virus (ATV) has been isolated from populations of the Sonoran Tiger Salamander (A. stebbinsi) in Arizona, and periodically causes mass mortality in populations of this subspecies (Jancovich et al. Allometric morphological variation across species and populations is known to functionally affect escape behavior and locomotion in other study systems (Vanhooydonck et al.

Using the landscape variation of a glacial valley in the Greater Yellowstone Ecosystem as the context for a natural experiment, we examined variation in growth pattern and life history of the salamander Ambystoma tigrinum melanostictum and determined how these developmental characteristics varied with hydroperiod over several summers.
