Ecological insights from bacterial networks
… gene transfer (HGT) and differences in the geography, ecology and phylogenetic history of each pair of genomes. Of these influences, ecological overlap is the most important force shaping recent gene exchange. In the second chapter, I use CRISPR arrays as a record of recent infections to …

What’s in a Tooth? Signals of Ecogeography and Phylogeny in the Dentition of Macaques (Cercopithecidae: Macaca)
… Macaca). To this end, the relationship between geography, ecology, phylogeny, and phenotypic variation among macaques was investigated. Constraints to phenotypic variation – and thus evolution – were also analysed in the form of observed amounts of phenotypic variation and patterns of phenotypic …

Holocene floodplain vegetation dynamics and sea-level change in the lower Aire valley, Yorkshire
Perimarine river valleys are a rich resource for studying palaeoecological change which may provide information concerning catchment and sea-level change. This thesis reconstructs the environmental history of the lower Aire valley during the Holocene, and investigates the factors influencing …

An assessment of the relationships between the surface soil properties and components of slope and vegetation in the Upper Wadi Bishah Basin, Saudi Arabia
This study, the first of its kind undertaken in Saudi Arabia, investigates and evaluates the condition of soil and vegetation and the relationship between them, as well as their relationship with slope components in the Upper Wadi Bishah basin, south-west Saudi Arabia. It is based mainly on …
