Observed localities for three endangered, endemic Mexican ambystomatids (Ambystoma altamirani^A. leorae, and A? rivulare) from central Mexico

摘要

The populations of ambystomatid salamanders around Mexico City are subject to a variety of threats, and some populations may be in decline. Three Ambystoma species found around Mexico City and in central Mexico are A. altamirani, A. leorae, and A. rivulare, and these three species are subject to a variety of conservation threats. We compiled a database of localities for these ambystomatid salamanders. The compiled observations of these three species of endangered salamanders suggest several patterns: 1) most localities for all three species are in the Estado de Mexico, including several for A. altamirani within the borders of Mexico City; 2) there is little, if any, geographical overlap among these three species; 3) the relatively few documented sites for A. leorae and A. rivulare highlight their tenuous conservation status. Our hope is that this presentation of a map of documented locations of these three Mexican Ambystoma has created a starting point for future studies on these salamanders.
