The Ontogenetic Effects On The Shell Strength Of Turtles, Dakota Wayne Speck
The Ontogenetic Effects On The Shell Strength Of Turtles, Dakota Wayne Speck
Undergraduate Honors Thesis Collection
The shell of a turtle acts as its first line of defense by resisting the compressive forces applied by a potential predator. Changes in shell size and shape that are associated with ontogenesis and sexual dimorphism have been shown to greatly impact the strength a turtle's shell in a variety of species. Here I have tested the effects of ontogenetic changes on the shell strength of Graptemys geographica. The results suggest that the morphological changes that occur during ontogenesis work to increase the overall strength of the shell. The data did not show any obvious morphological or mechanical differences between …

Various Gaits Of African Elephant Calves, Elizabeth Anne Jennings
Undergraduate Honors Thesis Collection
It is commonly believed that elephants exhibit only one gait, a lateral sequence walk. However, recently there have been several interesting studies on the footfall patterns of adult African elephants (Loxodonta africana). Scientists have recognized that elephants actually exhibit two patterns of locomotion: a lateral sequence walk and an amble. The amble is a slight modification of the lateral sequence gait. The present study extends this work by examining the relationship between gait and speed in African elephant calves at the Indianapolis Zoo. I collected frame-by-frame observational video data from a newborn calf born at the Indianapolis Zoo across a …
