The immunobiology of the Asian clam, Corbicula fluminea /
(1984)
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 ...
Erythrocytic phosphates in amphibians.
(1981)
Enzymatic, colorimetric and/or ion-exchange chromatographic analyses of amphibian erythrocytic organic phosphates (EOPs) were performed to: (1) explore interspecific diversity, (2) determine the intraspecific effects of ...
Critical thermal maxima and thermal tolerance in small mammals.
(1981)
The CTM was then used to compare the thermal tolerances of five species of small mammals (laboratory mice, Mus musculus; white-footed mice, Peromyscus leucopus; gerbils, Meriones unguiculatus; laboratory rats, Rattus ...
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 ...
Karyotypic, morphologic, and genic differentiation of hybridizing ground squirrels (Spermophilus mexicanus and Spermophilus tridecemlineatus).
(1982)
Levels of fluctuating asymmetry were measured to try to assess the fitness of the hybrids relative to the parentals. Hybrid asymmetry was greater than that of S. mexicanus but tended to be less than the levels of asymmetry ...
Genotype x environment interactions in Drosophila melanogaster /
(1983)
Chapter II. Conditional Polygenic Effects in the Sternopleural Bristle System of Drosophila Melanogaster. II. Polygene Mapping. The intrachromosomal architecture of third chromosomes isolated from lines of Drosophila ...
A morphological study of larval forms of North American species of Stenelmis (Coleoptera : Elmidae)
(1980)
Fourteen species of Stenelmis from North America were studied: S. beameri, S. bicarinata, S. crenata, S. exigua, S. gammoni, S. grossa, S. mera, S. parva, S. sandersoni, S. sexlineata, S. vittipennis, and three undescribed ...
Plumage coloration and dominance behavior in three species of sparrows of the genus Zonotrichia.
(1983)
I investigated the general hypothesis that plumage variability in winter flocking birds acts as a status signal using three species: Harris' sparrow (Zonotrichia querula), white-crowned sparrow (Z. leucophrys) and ...
