Urban aquatic habitats and conservation of highly endangered species: the case of Ambystoma
mexicanum (Caudata, Ambystomatidae).
altamirani used sites with mud bottoms more than expected and sites with gravel and bedrock substrates less than expected (96 mud, 9 mud with gravel, 0 gravel, 0 bedrock, 9 sand) relative to the total number of sites with each bottom type (272 mud, 56 mud with gravel, 15 gravel, 57 bedrock, 45 sand; [[chi square].
There have also been declines of the Lago de Patzcuaro salamander Ambystoma
dumerilii; its fishery registered 6 ton in 1987, <3 ton in 1998 and < 0.
Of the three species of Ambystoma
taken at Dave's Pond, the small-mouthed salamander was by far the most numerous.

To determine if our estimate of measurement variation could be considered within the acceptable levels for research, we derived CV values for 38 populations of Ambystoma
tigrinum virus; Comm, commercial; Conc, concentration; FS, field survey; NA, not applicable (used when there were too few concentrations to evaluate nonmonotonicity); ND, not detected; PE, pulse experiment; SR, static renewal experiment.

The Spotted Salamander, Ambystoma
maculatum, is common throughout forests of eastern North America.
Some 17 species of tiger salamanders live in North America, and California's Ambystoma
californiense thrives in pools that dry out as summer progresses.
Pinder and Friet (1994), in particular, showed that oxygen production by the unicellular green alga Oophila ambystomatis has an enormous effect on oxygen profiles in egg masses of the spotted salamander Ambystoma
maculatum and is likely the sole source of oxygen for more central embryos late in development.
El lago es hogar de 2 especies endemicas: un tipo de charal conocido como Poblana alchichica alchichica y el ajolote Ambystoma
Abundant habitat exists on the site for pond breeding caudates of the genus Ambystoma
, which utilize ephemeral (and hence largely fish-free) bodies of water like those that exist in many of the flooded forest areas in KMWA.
The objective of this study was to characterize the biological actions of methoprene acid (MA), a metabolite of the insecticide methoprene, on a developing axolotl, Ambystoma
mexicanum, and to assess levels of developmental stability following treatment of embryos and hatchlings.
