The Basicranial Anatomy Of The Nimravidae (Mammalia: Carnivora): Character Analyses And Phylogenetic Inferences, Nancy Ann Neff

Dissertations, Theses, and Capstone Projects

The phylogenetic relationships of the Nimravidae (Oligocene through latest Miocene catlike carnivorans) are controversial: they have been placed either within the family Felidae, or as sister group to the Felidae, to the modern aeluroid Carnivora, or to the Caniformia. Adoption of cladistic analysis is not sufficient to resolve this controversy: all of the last three hypotheses of relationship have resulted from cladistic analyses.

Competing hypotheses of phylogenetic relationship are here demonstrated to be primarily the result of disagreement about the identification and distribution of characters. Such disagreements reflect the need for a rigorous method of character analysis to enable explicit …

The Effects Of Forebrain Ablations On Some Behaviors In Xenopus Laevis, Lawrence Paul Kunstadt

Dissertations, Theses, and Capstone Projects

In order to further elucidate the hypothesis that the telencephalon of ectothermic vertebrates functions primarily as a non-specific arousal mechanism, facilitating lower brain areas, (the Arousal Hypothesis) the South African clawed frog, Xenoous laevis, was studied in four behavioral situations before and after telencephalon ablation, olfactory bulb ablation or sham surgery. Particular attention was paid to measurements of the temporal aspects of the behaviors studied.

The behaviors studied were:

1. Habituation to an acoustic-vibratory stimulus

2. The optomotor response

3. Escape from shallow water

4. Feeding behavior

In the habituation experiment no changes were found in the number of …
