ABSTRACT
The Huachuca springsnail (Pyrgu/opsisthompsoni) is a species of concern
inhabiting springs of the HuachucaMountainsin southeasternArizona, USA. We
documented springsnail distribution and examined the major abiotic and biotic factors
influencing springsnail abundance at eight spring channels before and after the onset of
seasonal summer rains in 2003. Of the abiotic factors examined (total dissolved solids, pH,
distance trom spring source, spring channel, water temperature, and dissolved oxygen),
only spring channel and total dissolved solids were strongly associated with springsnail
abundance. However, correlation of total dissolved solids with pH, temperature, dissolved
O2, and distance downstream necessitated further exploration of these explanatory
