Only a few tolerance and toxicity studies have been conducted
on T. mariae, including responses to changes in temperature,
dissolved oxygen, copper, glyphosate and benzocaine. In Florida,
preferred temperatures of introduced brood-stock were
assessed after acclimation to various temperatures (Siemien and
Stauffer 1989). After an acclimation temperature of 158C, the
preferred temperature was 25.28C, and after acclimation at 208C
the preferred temperature was 31.38C. The preferred temperature
after acclimation at 25–358C was 33.08C. In Roger Springs,
Nevada, the species is established at temperatures of 28–298C
