Accuracy Assessment of Skeletochronology in the Arizona Tiger Salamander (Ambystoma tigrinum nebulosum)
(American Society of Ichthyologists and Herpetologists (ASIH), 2007-05-16)
Skeletochronology is the most commonly used tool for evaluating the age of amphibians and reptiles. However, the accuracy of skeletochronology is questionable because few studies have utilized individuals of known age to ...
Foraging tactics in alternative heterochronic salamander morphs: trophic quality of ponds matters more than water permanency.
1. In lentic freshwater habitats, the composition of animal assemblages shifts along a gradient from temporary to permanent basins. When habitats with different degrees of permanence are at the scale of the home range of ...
Foraging trade-offs along a predator-permanence gradient in subalpine wetlands
(Ecological Society of America, 1999-09)
We conducted a series of field and laboratory experiments to determine the direct and indirect effects of a top predator, the tiger salamander (Ambystoma tigrinum nebulosum), on larvae of two species of limnephilid caddisflies ...
Growth and foraging consequences of facultative paedomorphosis in the tiger salamander
(Chapman & Hall, 1996-07)
Facultative paedomorphosis in salamanders occurs when larvae respond to varying environmental conditions by either metamorphosing into terrestrial metamorphic adults or retaining their larval morphology to become sexually ...
Fluctuation in a Rocky Mountain population of salamanders: Anthropogenic acidification of natural variation?
(Society for the Study of Amphibians and Reptiles, 1992)
We monitored the demographics of the salamander Ambystoma tigrinum nebulosum as part of a community-wide study on the effects of acidification in sub-alpine (elevation 3600 m) ponds in central Colorado. A decline in A. ...
Differences in the Antipredator Behavior of Three Plethodontid Salamanders to Snake Attack
