Hawker, James 1978 Journal Ambystoma collecting in Mexico, Hidalgo, and Michoacan 20-24 Dec meadow beside the highway. The Nopaltepec growing animals were taken in the small pool that was all that remained of the large pond of last summer. We next worked a locality suggested by Brad Shaffer NW of Toluca. We found small artificial muddy cattle ponds adjacent to a stream beside the highway and seined 14 larvae. The surrounding habitat is nearly deroid of trees, being mostly corn fields. The ponds would appear to be temporary; I can't imagine where the adults would take shelter. Yesterday we visited several permanent and temporary ponds ~ 12 mi. W of Morelia but found no Ambystoma, although all ponds had R. pipiens. The permanent ponds had small fish which might limit occupancy by Ambystoma. Today we drive from Morelia to Mexico City and leave tonight for the US.
