The Evolutionary Ecology of Parasitic Strategies: Experimental Evolution with a Facultatively Ectoparasitic MiteDownload
Although parasitism is a ubiquitous lifestyle, little empirical evidence exists for how and why parasitism evolves from free-living lineages. Analysis of phylogenetic relationships among taxa that exhibit a range of lifestyles has aided in the development of a commonly proposed hypothesis for the...
A high-density SNP-based linkage map of the chicken genome reveals sequence features correlated with recombination rateDownload

Development, Anatomy, and Phylogenetic Relationships of Jawless Vertebrates and Tests of Hypotheses about Early Vertebrate EvolutionDownload
The origin and early evolution of vertebrates remain one of the central questions of comparative biology. This clade, which features a breathtaking diversity of complex forms, has generated profound, unresolved questions, including: How are major lineages of vertebrates related to one another?...
Ethical reasoning in normative and practical ethics is typically conducted by working back and forth between intuitions about both general moral principles (e.g., suffering is bad) and particular cases (e.g., that I must prevent a specific person from suffering). These two types of...
Leafrollers moths are one of the most ecologically and economically important groups of herbivorous insects. These Lepidoptera are an ideal model for exploring the drivers that modulate the processes of diversification over time. This thesis analyzes the evolution of Choristoneura Lederer, a well...
Gene expression and sensory structures in sponges: Explorations of sensory-neural origins in a non-bilaterian contextDownload
The nervous system is present in all but two animal phyla – one of them being Porifera, sponges. Sponges have no neurons and yet have organized behavior and finely tuned sensation. Furthermore, sponges have genes involved in the nervous system of other animals (informally called ‘neural’ genes)....
Three species of Cretaceous marine squamates are described or redescribed. The first, Pontosaurus ribaguster is described from a relatively complete specimen discovered on Hvar Island, Croatia. Preservation of identifiable nektonic teleosts within the gastric cavity (the first identifiable...
Respiration, Acid/Base, Ammonia and Ionoregulatory Strategies in the Pacific hagfish (Eptatretus stoutii)Download
Hagfish feed on putrefied carrion, which poses several environmental challenges to the scavenger including hypoxia (Low PO2), hypercapnia (high PCO2) and high environmental ammonia (HEA). To any other organism, these conditions would be physiologically challenging; however, hagfish seem to have...
The emission of propagating MHD waves from the boundaries of flow channels that are unstable to the Kelvin-Helmholtz Instability (KHI) in magnetized plasma is investigated. The KHI and MHD wave emission are found to be two competing processes. It is shown that the fastest growing modes of the KHI...
One of the features that distinguishes eukaryotes from prokaryotes is the membrane trafficking system. This system underpins much of the functionality of the eukaryotic cell, and is necessary for feeding, motility and communication. Analyses aimed at addressing the evolution of this system have...
