A proposed homology between the reptilian dorsomedial thalamic nucleus and the mammalian paraventricular thalamic nucleus.

We have compared the reptilian dorsomedial thalamic nucleus with the mammalian paraventricular thalamic nucleus from a topographic, chemoarchitectonic, and hodological point of view. Both nuclei are localized to a similar position in the dorsalmost aspect of the dorsal thalamus (midline nuclei). They also are uniformly calretinin-immunoreactive, both their cells and neuropil are strongly immuno...

Localization of Monoamine Oxidase in Mammalian and Reptilian Heart.

Numerous studies have been reported concerning the role of monoamine oxidase (MAO) in the metabolism of biogenic amines, especially in the central nervous system and in the heart. A large number of compounds that inhibit MAO have been described, and some of these have been used therapeutically. For this reason we considered that differences in concentration and localization of the enzyme might ...

Competition for the invitro binding of radioiodinated human follicle-stimulation hormone in reptilian avian, and mammalian gonads by nonmammalian gonadotropins.

Radioiodinated human FSH (‘?-hFSH) was used to study the specificity of the gonadotropin binding sites of various reptilian, avian, and mammalian gonadal tissues by examining competitive interactions with several nonmammalian gonadotropins. All preparations of nonmammalian gonadotropins showed some activity in these radioligand assays, but wide variations in activities were evident depending on...

Niche overlap and diffuse competition.

Current theory predicts a distinct upper limit on the permissible degree of niche overlap; moreover, theory suggests that maximal tolerable overlap should be relatively insensitive to environmental variability. Data presented here demonstrate that, within the lizard subset of natural desert communities, niche overlap decreases both with increasing environmental variability and with increasing n...

ELISE . Mammalian Nest Predators Respond to Greenway

NOVOTNY, KRISTEN ELISE. Mammalian Nest Predators Respond to Greenway Width, Habitat Structure, and Landscape Context. (Under the direction of George R. Hess.) Birds of conservation concern breed in suburban greenways, yet abundant populations of mammals that depredate bird nests may compromise nest success. We evaluated how three factors influenced total mammalian nest predator abundance and in...
