The freshwater bivalve, Corbicula fluminea, was selected for the study of the internal defense mechanisms of hemocoelic invertebrates. Corbicula hemocytes, the primary effector cells involved in defense reactions, consisted ...
Aerial versus aquatic gas exchange in salamanders in response to environmental hypercapnia /
(1984)
All animals, acclimated at 20(DEGREES)C and LD 12:12, were subjected to a 3 hr control period of normoxic normocapnia in both media. Necturus was then exposed to aquatic hypercapnia of P(, CO(, 2)) = 20-130 mm Hg, and the ...
Feeding ecology of juvenile turtles (Chrysemys) under experimental conditions /
(1984)
A foraging model that predicts the net energy intake for juvenile turtles feeding on a range of Callibaetis nymph sizes is also examined. Those nymph sizes that miximize the net energy intake in the model are considered ...
Ecology of Helicopsyche borealis (Hagen) (Trichoptera : helicopsychidae) :
(1984)
The life history and microdistribution of Helicopsyche borealis was compared for a 13-month period in two Oklahoma streams that have different thermal regimes. Densities of H. borealis were usually higher in the thermally ...
