Ecological changes in the phenology and distribution of plants and animals mediated by changes in the environment are occurring across the globe and have been documented for a wide range of species. However, determining the specific mechanisms that affect the life-history parameters of organisms is typically difficult. Measuring population trends over time, and in relation to broad-scale environmental state, is one of the simplest ways of linking the effects of physical environmental variation to its direct effects on biological systems. This study is concerned with describing key life-history parameters and population demography of a wide-ranging and abundant pelagic seabird, the short-tailed shearwater (Puffinus tenuirostris). The population demography of this uppertrophic consumer is investigated directly within the context of its spatio-temporal use of the marine environment and its response to environmental variation. In this thesis I present data and analyses for: 1. Population trends of short-tailed ...
