macrodactylum also inhabit some of these deeper MORA lakes (Larson and Hoffman 2002, 2004; Hoffman and others 2003), but this salamander species is predominately associated with shallower ponds (0.
The polytypic species revisited: genetic differentiation and molecular phylogenetics of the tiger salamander Ambystoma
tigrinum (Amphibia: caudata) complex.
It therefore appears that the specific sites where Mexican Ambystoma
deposit their eggs may be plastic or vary from species to species or even from population to population.
The absence of Ambystoma
dumerilli, Skiffia lermae and Allotoca dugesii in our collections and the few individuals captured of Allotoca diazi, Algansea lacustris and Allophoorus robustus may indicate ecosystem degradation via the loss of their reproductive habitat and alterations to their food resources.
Seining that day yielded 1 chorus frog (ISU 871) along with 12 Ambystoma
texanum, 5 A.
Organophosphorus pesticides effect on early stages of the axolotl Ambystoma
mexicanum (Amphibia: Caudata).
2007: Spot symmetry predicts body conditions in spotted salamanders, Ambystoma
2006b) revealed significant and delayed declines in Ambystoma
barbouri salamander populations at 4, 40, and 400 [micro]g/L atrazine, above and beyond the counteracting effects of density-mediated compensation.
Observations on the eggs of Ambystoma
maculatum with special reference to the green algae found within the egg envelopes.
Semlitsch and Wilbur (1988) report accelerated development in the salamander Ambystoma
talpoideum in response to an experimental drawdown of water level, which simulates pool drying; however, Wilbur (1987) found that such drawdowns in field conditions are associated with increased variance in temperature, which might also influence development rate.
Recent research (Irscbick and Shaffer 1997, Shaffer and McKnight 1996) has questioned the taxonomic status of Ambystoma
tigrinum, suggesting that the eastern tiger salamander is a distinct species separate from the other recognized forms.
There are two endemic vertebrate species inhabiting the lake: the atherinid fish Poblana alchichica alchichica de Buen 1945 (Alvarez 1950) and the ambystomid salamander Ambystoma
taylorii (Taylor 1943, Brandon et al.
