Introduction
I'm a Marine Ornithologist at Marine Scotland Science, working as part of the MarPAMM project. I completed my PhD at the Centre for Ecology & Hydrology Edinburgh and the University of Liverpool in 2019, using long-term data on European shags breeding on the Isle of May, Scotland. I have previously worked in Ecological Consultancy, Environemntal Education and as a Volunteer Coordinator.

Long-term changes in climate are affecting the abundance, distribution and phenology of species across all trophic levels. Short-term climate variability is also having a profound impact on species and trophic interactions. Crucially, species will experience long- and short-term variation simultaneously, and both are predicted to change, yet studie...
Populations of marine top predators are exhibiting pronounced demographic changes due to alterations in prey availability and quality. Changes in diet composition is a key potential mechanism whereby alterations in prey availability can afect predator demography. Studies of long-term trends in diet have focused on the breeding season. However, long...
The earth's climate is changing rapidly, with pronounced impacts observed in all well studied ecosystems throughout the globe. Climate-mediated impacts are particularly marked and rapid within marine ecosystems. At the apex of such systems, marine top predators, such as seabirds, are vulnerable to direct and indirect climate-mediated effects, which...
Offshore renewable developments (ORDs) may negatively affect seabirds, in particular due to collisions with turbine blades, displacement to less favourable habitats and barrier effects to movement. Many so-called 'sub-lethal effects', whereby individuals birds are not killed instantaneously by an interaction with the wind farm, but behaviour is aff...
As temperatures rise, timing of reproduction is changing at different rates across trophic levels, potentially resulting in asynchrony between consumers and their resources. The match–mismatch hypothesis (MMH) suggests that trophic asynchrony will have negative impacts on average productivity of consumers. It is also thought to lead to selection on...
The article Pronounced long-term trends in year-round diet composition of the European shag Phalacrocorax aristotelis, written by Richard J. Howells, Sarah J. Burthe, Jonathan A. Green, Michael P. Harris, Mark A. Newell, Adam Butler, Sarah Wanless and Francis Daunt, was originally published electronically on the publisher’s internet portal (current...
