Abstract:

The study of phylogeny, i.e. the evolutionary history of species, is a central problem in biology and a key for understanding characteristics of contemporary species. Many problems in this area can be formulated as combinatorial optimisation problems which makes it particularly interesting for computer scientists. The reconstruction of the phylogeny of species can be based on various kinds of data, e.g. morphological properties or characteristics of the genetic information of the species. Maximum parsimony is a popular and widely used method for phylogenetic reconstruction aiming for an explan

Abstract:

Geometric morphometrics, the science about the study of shape, has developed much in the last twenty years. In this thesis I first study the reliability of the phylogenies built using geometric morphometrics. The effect of different evolutionary models, branch-length combinations, dimensionality and degrees of integration is explored using computer simulations. Unfortunately in the most common situations (presence of stabilizing selection, short distance between internal nodes and presence of integration) the reliability of the phylogenies is very low. Different empirical studies are analysed

<p>This thesis focuses on phylogenetic and taxonomic studies of Catenulida (Platyhelminthes). Catenulida is a group of microscopic free-living worms mainly found in freshwater habitats. The Swedish catenulid fauna was previously virtually unknown.

Based on two molecular markers, 18S rDNA and 28S rDNA, the phylogenetic position of Catenulida has now been well established as the siste

Abstract:

Though molecular phylogenetics has been very successful in reconstructing the evolutionary history of species, some phylogenies, particularly those involving ancient events, have proven difficult to resolve. One approach to improving the resolution of deep phylogenies is to increase the amount of data by including multiple genes assembled from public sequence databases. Using modern phylogenetic methods and abundant computing power, the vast amount of sequence data available in public databases can be brought to bear on difficult phylogenetic problems.

Abstract:

Echinoderms are a highly diverse phylum of marine invertebrates with a good fossil record that extends back 550 million years. The work presented here is a contribution towards documenting their long history both in terms of phylogenetic branching pattern and evolutionary biology. Taxonomy is the primary means by which evolutionary processes can be studied because it is through taxonomy that species are recognised and their relationships to one another established. Taxonomy at various levels thus forms a major part of the thesis. Species are documented and described both for specific time inte

Abstract:

The Pterosauria is an enigmatic group of volant reptiles from the Mesozoic. Despite demonstrating conspicuous apomorphic conditions, including an enlarged humeral deltopectoral crest, elongate wing spar comprising the fourth manual digit, and unique skull bone configurations, their cladogenesis is uncertain. While the ingroup monophyly of Pterosauria is clear, their interrelationships are contentious. The earliest studies of pterosaur phylogeny were concerned with phenotypic groups. The earliest cladistic analyses of pterosaurs in the late 20th Century were simple and were superseded by more c

Phylogenetically the closest species were the great tit (Parus major) and the blue tit (P. caeruleus). Subgenus Poecile was divided into two clades, one consisting of the Siberian tit (P. cinctus), the Carolina chickadee (P. carolinensis) and the Black-capped chickadee (P. atricapillus) and the other consisting of the marsh

Abstract:

Thought of as "ancient" fishes, 25 broadly recognized extant sturgeon species are classified in four genera (Acipenser, Huso, Pseudoscaphirhynchus, and Scaphirhynchus). Molecular and morphological analyses have led to broad but conflicting changes to sturgeon phylogeny. For example, the position of Scaphirhynchus among other sturgeons had been contentious, and various sets of sturgeon species have been proposed to make up the subfamily Husinae. Here, a molecular phylogeny of sturgeons, based on the full mitogenome, is presented. In this phylogeny, Scaphirhynchus is recovered with strong supp
