Research title: Pathology of Strandings Surveillance Data
The marine environment is rapidly changing, most notably following developments in renewable energy industry and perennial pressures from fisheries, which befall against a backdrop of climate change that is occurring at a rate faster than previously recorded. The need to assess, quantify, and mitigate specifically anthropogenic pressures and impacts on marine ecosystems is therefore ever more pressing.
Marine mammals are charismatic megafauna which are recognised as useful indicator species, representing general ecosystem and ocean health. Surveillance of marine mammal species at sea is however notoriously difficult, with even the most basic population metrics being largely hidden from direct observation. A number of the animals that die at sea end up stranding on the shore, making the coastline a very powerful vantage point from which to undertake surveillance.
While information acquired through strandings surveillance often can not be gathered by any other means, strandings data is generated through a complex function of biological, physical, and social processes which are all interlinked and introduce varying levels of bias. As a consequence, there is still a lot of uncertainty around the extent to which you can use information obtained through examinations of stranded individuals to make population level inferences, and how representative the strandings surveillance datasets are of at sea mortality. This hinders progress and makes that strandings datasets are currently underutilised in the context of evidence-based population management and the development of policy.
My research will focus on improving the statistical modelling techniques for strandings data to facilitate their use for population monitoring. I am hoping to develop a modelling framework that is able to better account for the biases associated with the strandings process, and reduce uncertainty in quantifying anthropogenic impacts on marine populations. Through this I hope that we can expand the use of strandings datasets for population ecology and conservation management – and guide future surveillance and management of marine ecosystems.
While this research will focus on marine strandings, my wider interest concerns the development of quantitative methods to maximise information from opportunistically collected datasets, to address questions in complex biological systems.
