Abstract:

The evolutionary history of archosauromorphs is of particular interest because it includes the origins of two of the best-known and most distinctive extant tetrapod groups: crocodylians and birds. In this thesis, the anatomy, taxonomy and systematics of the Permo-Triassic non-archosaur archosauromorphs are revised. A revision of the Permo-Triassic archosauromorph record indicates that only four Permian species are known and there are three valid proterosuchid species immediately after the Permo-Triassic boundary in South Africa. Analyses of cranial ontogenetic variation in \(Proterosuchus\) \(

Abstract:

Recognizing the mechanisms of speciation and the limits of species is essential to understand the origin of biodiversity and how to conserve it. The general aims of my investigations during my doctoral studies were two-fold: to study evolutionary patterns and processes, and to provide specific and superspecific taxonomic classifications that try to reflect evolutionary history. I have focused my research on anurans in their biodiversity hotspot, the American Tropics. I have used morphological, behavioral (mating calls), and genetic (DNA sequences) characters to study species boundaries between

Abstract:

Fireflies are a cosmopolitan group of bioluminescent beetles classified in the family Lampyridae. The first catalogue of Lampyridae was published in 1907 and since that time, the classification and systematics of fireflies have been in flux. Several more recent catalogues and classification schemes have been published, but rarely have they taken phylogenetic history into account. Here I infer the first large scale anchored hybrid enrichment phylogeny for the fireflies and use this phylogeny as a backbone to inform classification. Several classification changes are made throughout the group wit

Abstract:

Heterostracans are extinct armoured jawless vertebrates and are hypothesized to be positioned as sister group to all other boney vertebrates - they are therefore fundamental to understanding early vertebrate evolution. Despite being taxonomically the largest clade of stem gnathostomes (jawed vertebrates), they lack the evolutionary framework required to further explore marcoevolutionary patterns and transitions. This thesis therefore aims to address one over arching theme: understanding the evolution and diversity of the Heterostraci and by extension, that of early vertebrates. This was first

This dissertation focuses on increasing the understanding of the evolution processes that have contributed to the diversification of freshwater crayfish. Chapter one estimates the divergence time of the three crayfish families and tests the hypothesis that diversification is tied to the break-up of Pangaea, Gondwanna, and Laurasia. I find that the families of crayfish diverged prior to or in association with the break-up of the three super continents.

Abstract:

Snapping shrimp in the family Alpheidae are remarkably abundant in coral reef ecosystems worldwide. The second most speciose genus, Synalpheus , includes species usually small and reclusive, and their general morphology is notably uniform, yet the number of species is staggeringly high, as is the intraspecific variability. These features have contributed to a poorly resolved taxonomic status, as evidenced both by recurring lumping and splitting of species and by lack of proper definition of several common species. I examined western Atlantic species of Synalpheus in the large and regionally do

Abstract:

Historical structuralism is presented as a research program in evolutionary biology. It uses patterns of common ancestry as initial hypotheses in explaining evolutionary history. Such patterns, represented by phylogenetic trees, or cladograms, are postulates of persistent ancestral traits. These traits are evidence of historical constraints on evolutionary change. Patterns and processes consistent with a cladogram are considered to be consistent with an initial hypothesis of historical constraint.

In Part I I discuss normativity in epistemology and meta-epistemology. I begin by drawing attention to the fact that there are very different ways of understanding which co

For direction one, I evaluate the relationships of 96% of pitvipers by combining independent sets of molecular and phenotypic data.

As a result, the activity of Hsp90 has the potential to influence physiology, which in turn may influence the ability to adapt to new environments.

Abstract:

Sequence-function relationship is a fundamental question for many branches of modern biomedical research. It connects the primary sequence of proteins to the function of proteins and fitness of organisms, holding answers for critical questions such as functional consequences of mutations identified in whole genome sequencing and adaptive potential of fast evolving pathogenic viruses and microbes. Many different approaches have been developed to delineate the genotype-phenotype map for different proteins, but are generally limited by their throughput or precision. To systematically quantify the

Abstract:

Gratiola (Plantaginaceae tribe Gratioleae) is a genus of ca. 33 wetland-adapted herbaceous species found mostly in temperate or tropical-montane regions of the Americas, Eurasia, and Australasia. The only worldwide taxonomic treatment of Gratiola was published more than 160 years ago and only a few representatives of the genus have been included in published molecular phylogenetic studies. The overall aim of this investigation was to provide a modern systematic study of Gratiola by determining the phylogenetic placement of Gratiola within the Gratioleae using chloroplast DNA sequence data (Cha

Abstract:

Climate change has been invoked to explain patterns of speciation, extinction and biogeographic change over time, however it can be a difficult hypothesis to test empirically. One area of particular interest is climate change in the African Neogene, linked with the origin of hominins. A perfect model clade to test these hypotheses is the papionin monkeys, a diverse group (both extinct and extant), represented by an excellent fossil record. I describe new fossil papionin specimens from Coopers Cave, South Africa, and redescribe and discuss some previously known fossil material. This rich da

Abstract:

The excellent penguin fossil record is temporally long, among the oldest of modern birds, and contains fossils on every Gondwanan continent except India. However, most of fifty-nine named taxa are isolated skeletal elements, many of which are noncomparable. Fossil diversity is highest in New Zealand, with additional Antarctic and Patagonian faunas and fewer remains from Australia and South Africa. Phylogenetic hypotheses place penguins within Aves and Neornithes, but further relationships remain contentious. Recent work clarified living species' phylogeny, but none examined all fossil taxa. I
