Associations between aquatic habitat variables and pyrgulopsis trivialis presence/absence

Abstract

We evaluated associations between physicochemical aquatic habitat variables and presence/absence of Pyrgulopsis trivialis, a hydrobiid snail, in selected springs at Three Forks springs and Boneyard Bog springs in the White Mountains of eastcentral Arizona. Three Forks springs were characterized by more cobble/boulder and gravel/pebble substrates, higher water temperature, lower conductivity, higher pH, and deeper water than Boneyard Bog springs, which were characterized by more silt/sand substrates and watercress. The presence of P. trivialis was associated with gravel/pebble substrates, shallower water, higher conductivity, higher pH, and presence of Physa gyrina. © 2008, Copyright Taylor & Francis Group, LLC.
