Plant-Pollinator Interactions in an Ecological and Evolutionary Context: The Promising Role of 3D-Printing Technology and Mathematical Modeling
This dissertation concerns itself with the role of flower shape in affecting the foraging performance of pollinating animals. The pollinator used in this study is a model organism representing crepuscular hawkmoths in research involving the study of flight neuromuscular physiology and plant-pollinator interactions, Manduca ...
Sex and Fear: Mathematical models of mate choice, parental care, and maladaptive anxiety
In many contexts, animals must infer salient information about another individual indirectly by observing some other characteristic of that individual. In Chapter 1 of this thesis, a model of costly signaling is developed to investigate how stochastic signal costs influence the overall cost of communication. Chapter 2 presents ...
Of E. coli and classrooms: stories of persistence
Plasmids exist in bacteria and are small, extrachromosomal pieces of DNA that often encode accessory genes such as antibiotic resistance genes. They are largely responsible for spreading antibiotic resistance genes through bacterial populations via their ability to conjugate into different bacterial hosts or species. In ...
Homodonty and Heterodonty - an iconoclastic view of teeth
Teeth are perhaps one of the most readily identifiable traits that categorize vertebrates. Indeed, much of what we know about human evolution is based on fossilized teeth. In a similar manner the teeth of other vertebrates can serve as an important clue in identifying the relationship between the morphology of the organism ...
