Finding rules that govern species distribution and coexistence is a fundamental aim of ecological research. The rapidly expanding and increasingly mobile human race is challenging our understanding of some these rules. Using long-term macroinvertebra

At the St Kilda archipelago, Outer Hebrides, declines have been recorded in the Leach's Storm-petrel breeding population, the largest in Britain and Ireland, and rapid increases in the population of Great Skuas. Leach's Storm-petrels have frequently

Individuals have limited time and energy and so they face a trade-off between the resources they allocate to parental, mating and self-maintenance activities and between care of current and future offspring. Within a biparental system, models predict

Organisms are constantly altering their phenotypes in response to changing environments. Many of these differences are known to be due to genetic changes. However, some of the differences between individuals will be due to phenotypic plasticity. Phen

Conservation of phenotypically variable taxa such as the European whitefish (Coregonus lavaretus) can be particularly challenging. In this thesis it is argued that the recent designation of seven native C. lavaretus populations as three endemic speci

The ability of animals to vary growth, development rate and behaviour in response to environmental conditions has been well documented, particularly during the larval phase in animals with complex life cycles. The evolution and maintenance of plastic
