A long-standing question in evolutionary biology is whether adaptation will typically proceed through a few mutations with large selective effects or many mutations with small effects. Many studies have implicated few loci of major effect, but it has been predicted that small-effect mutations should exist and contribute to adaptation. However, such mutations have not been found in many studies, either because they do not exist or because the experimental design limited their detection. To determine the effects and types of mutations contributing to adaptation, I studied laboratory and wild po

The aim of this doctoral research is to understand domain evolution processes in ferroelectrics using piezoresponse force microscopy (PFM) and Monte Carlo simulation. The results provide improved knowledge of domain evolution processes, and systematic experimental methods for research on domain evolution. There has been extensive previous research on domain evolution in ferroelectrics, but the research was mainly constrained to simple domain patterns. However, ferroelectric domains tend to form complex patterns that generate low-energy domain configurations. In this research, several methods s

Mud volcano systems erupt sediment and fluid onto the Earth’s surface producing edifices up to 25 km3 in volume however, little is known about how such volumes are transported through the Earth’s crust. This thesis investigates whether transport is through mud-dyke-sill complexes, or is diapiric. Structural field mapping of exhumed mud volcano intrusive domains onshore in Azerbaijan, shows that feeder complexes are 200-800 m wide and roughly circular. These complexes consist of various fracture networks and a megabreccia of country rock blocks tens-of-metres-across that have rotated up to 90°

This thesis concerns evolution and how it is explained. The ambition here is to identify clearly the many aspects of evolution, and to evaluate past and present explanations of evolution for their coherence and validity. Historically natural selection has been taken to be the central and main explanans, with other explanations playing lesser roles. Here it will be argued that the sheer complexity and diversity within nature cannot be accounted for by any single explanatory mechanism and that a plurality of explanatory mechanisms is required.

We investigate the effects of colour evolution in QCD scattering processes and how these can be implemented in both analytical and numerical approaches. We split this in to four parts where each part is given in one chapter. In the first chapter we give a brief summary of the important aspects of QCD which are needed as a basis for the rest of the investigation. In addition to this, we describe different sets of formalisms for handling colour within interactions. We then give a brief review of the components of a Monte-Carlo event generator.

A fractal stochastic point process (FSPP) is used to model molecular evolution in agreement with the relationship between the variance and mean numbers of synonymous and nonsynonymous substitutions in mammals. Like other episodic models such as the doubly stochastic Poisson process, this model accounts for the large variances observed in amino acid substitution rates, but unlike other models, it also accounts for the results of Ohta's (1995) analysis of synonymous and nonsynonymous substitutions in mammalian genes.

There is a growing appreciation for the insight mathematical models can yield on biological systems.

Within genes, mutations that do not change proteins are usually considered 'silent' because it is assumed that they have no affect on an organism's phenotype. Evolution at silent sites is expected to be selectively neutral, so that the probability that a new mutation will become fixed in a population is dictated by chance. This is especially important in mammals, where small effective population sizes should reduce the ability of natural selection to influence the fate of mutations with presumed negligible impacts on fitness, such as silent nucleotide substitutions.

The evolution of mountain landscapes is controlled by complex interactions between large-scale tectonic, surficial and climate conditions. Dominant processes are attributed to creating characteristic features of the landscape, but topographic features are the cumulative result of coupled surficial processes, each locally effective in a different climate or elevation regime. The focus of erosion by glacial, fluvial, or mass wasting processes is highly sensitive to small changes in boundary conditions, therefore spatial and temporal variability can be high when observed over short time scales.

The Great Karoo spans the north-central part of South Africa at a major climatic boundary. The characteristics, spatial patterns and drivers of river channel response to Late Quaternary climate changes in the Sneeuberg, South Africa remain unclear due to the discontinuous alluvial stratigraphic record and the lack of dated palaeoclimatic archives. Dendritic channel networks in the upper Sundays River are deeply incised exposing terrace fills of varying thickness (2-6 m), extent (1 - > 10km) and pedogenic overprinting. Channels exhibit 'stepped' long profiles where resistant rock strata (doleri

The Mawddach Estuary and Barmouth Bay now occupy what was a deeply incised glaciated valley at the last ice maximum. This valley is now filled by a complex suite of sediments, up to 75m thick at the present estuary mouth, which record increasing marine influence. A regressive coastline is also present today. In the Bay, Welsh glacial drifts were eroded to form deep depressions, infilled by complex cross- stratified Late- or Postglacial sediments, overlain by a parallel-stratified sequence, perhaps formed behind a coast-parallel morainal barrier. Net sediment transport of the fine sand in the B
