The west coast of the Antarctic Peninsula is an ideal environment to examine ecosystem change. Over the past 50 years this region has been one of the most rapidly warming parts of the planet. However, the effect that this warming has, and will continue to have, on the Antarctic ecosystem is only now coming to light.
This project aims to identify if there have been changes in the dietary behaviour of populations of the top predator guild (the Weddell, crabeater, southern elephant and Ieopard seals) in the Western Antarctic system. We will first identify if there are regional differences in dietary behaviour between contemporary populations, and then examine behaviour back through time (prior to recent warming). We will use isotopic signatures of seal tissues to reconstruct dietary histories. Our sampling protocol uses seal tissues from historic and contemporary collections across a 140 year timeline. Populations have been sampled from four disparate regions: (1) the WAP area, experiencing environmental change, compared with regions experiencing less change: (2) the Weddell Sea, (3) the Davis Sea and (4) Commonwealth Bay.

You can combine search terms with and, or and/or not, e.g. Philo not logy.
You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).
Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.
You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).
If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
