Ecological context and the evolution of mating biases in a freshwater amphipod species complex.
(2007)
Mating traits are among the most extravagant traits found in nature. As with any trait, understanding the diversification of mating traits requires information on both direct and indirect selection acting on the traits and ...
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 ...
Physical characterization of the ecdysteroid and retinoid X receptor (UpEcR and UpRXR) in the fiddler crab Uca pugilator.
(2003)
Ecdysteroid hormones regulate growth, metamorphic differentiation, vitellogenesis, and oogenesis in insects. In crustaceans, molt, limb regeneration, and reproduction are closely related to ecdysteroid titers. In the fiddler ...
Privation and uncertainty in the small nursery of Peruvian laughing frogs: Larval ecology shapes the parental mating system.
(2002)
To determine how ecological factors of both offspring and adults can influence the adult mating system, I studied the parental care and mating behavior of the laughing frog, Osteocephalus planiceps. This species uses 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 ...
Sexual selection in a livebearing fish with a coercive mating system (western mosquitofish, Gambusia affinis).
(2006)
The livebearing fishes of the genus Gambusia are quickly becoming a model system to test alternative mechanisms of sexual selection in the form of coercive mating. I investigated effects of male and female body size, and ...
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 ...
Ontogeny of fear: Influence of corticosterone.
(2005)
A strong attachment to the caregiver is critical for survival in altricial species, including humans. While some behavioral aspects of attachment have been characterized, its neurobiology has only recently received attention. ...
Environmental constraints regulating the distribution and abundance of small mammals.
(1999)
I computed 15 landscape variables at four different scales (40 variables total). Cluster analysis of these weighted data produced three multispecies clusters based on associations of species distributions and abundances ...
