Abstract
ABSTRACT Collections of vertebrates and macroinvertebrates over two years from 26 lentic temporary water bodies each surveyed 1–4 times, in Ulster and Dutchess counties in the Hudson Valley of New York, USA, resulted in identifications of 166 species. These included species resident in temporary waters that have life stages resistant to drying and freezing, species that reproduce in temporary waters that need to mature before drying occurs, predatory species that visit temporary waters, and highly aquatic species that move overland to temporary waters. Temporary waters sampled had a range of hydroperiods from a few weeks to almost a year. Of the macroinvertebrates we identified to species, 75 were each collected in a single pool-survey (n = 62 pool-surveys). Pools with greater volume, more vegetation cover, lower pH and turbidity, and more sodium yielded greater species richness of macroinvertebrates, and species richness of certain taxa (eg Mollusca) were correlated with additional elements. We briefly discuss several unusual animal occurrences.
