As top predators, leopard seals play a disproportionately large role in ecosystem functioning; they also act as sentinel species that can track abiotic and biotic habitat changes. How leopard seals respond to a warming environment depends on their adaptive capacity\u2014a species\u2019 ability to cope with environmental change. However, leopard seals are one of the least studied apex predators on earth, hindering our ability to predict how the species is responding to polar environmental changes. Therefore, our objective is to determine leopard seals\u2019 adaptive capacity by quantifying their ability to move (dispersal ability), adapt (genetic diversity), and change (plasticity). In Aim 1, we will determine leopard seals\u2019 dispersal ability by assessing their distribution and movement patterns. In Aim 2, we will quantify genetic diversity by analyzing genetic variability and population structure. In Aim 3, we will examine plasticity by evaluating changes in their ecological niche and physiological responses. We have assembled an international, multidisciplinary Antarctic-experienced team to analyze existing data (e.g., photographs, census data, life history data, tissue samples, body morphometrics) collected from leopard seals across the Southern Ocean (e.g., South Shetland Islands, east and west Antarctica) over the last decade. Land- and cruise ship-based field efforts will generate comparable data from unsampled regions (e.g., Antarctic Peninsula, Chile, New Zealand,). By analyzing these historical and contemporary datasets, we will evaluate the adaptive capacity of leopard seals against the rapidly warming Southern Ocean.

While this is true of all marine mammals, variation in the physical and biological environmental is particularly profound in the Southern Ocean. A basic understanding of the foraging behavior and habitat utilization of pelagic predators requires knowledge of this spatial and temporal variation, coupled with information of how they respond to these changes. Current understanding of these associations is primarily limited to population level studies where animal abundance has been correlated with oceanography. Although these studies are informative, they cannot provide insights into the strategies employed by individual animals nor can they provide insights into the spatial or temporal course of these interactions. \u003cbr/\u003e\u003cbr/\u003eRecent technological advances in instrumentation make it possible to extend an understanding beyond the simple linkage of prey and predator distributions with environmental features. The key to understanding the processes that lead to high predator abundance is the identification of the specific foraging behaviors associated with different features of the water column. This study will accomplish these objectives by combining accurate positional data, measures of diving and foraging behavior, animal-derived water-column temperature and salinity data, and available oceanographic data. This project will examine the foraging behavior and habitat utilization of two species of contrasting foraging ecology, the southern elephant seal, Mirounga leonina, and the crabeater seal, Lobodon carcinophagus in the Western Antarctic Peninsula, a region of strong environmental gradients. Although these two species are phylogenetically related, they utilize substantially different but adjacent habitat types. Southern elephant seals are predominantly pelagic, moving throughout the southern ocean, venturing occasionally into the seasonal pack ice whereas crabeater seals range throughout the seasonal pack ice, venturing occasionally into open water. The relationship of specific foraging behaviors and animal movement patterns to oceanographic and bathymetric features develop and test models of the importance of these features in defining habitat use will be determined along with a comparison of how individuals of each species respond to annual variability in the marine environment. The physical oceanography of the Southern Ocean is inherently complex as are the biological processes that are intrinsically linked to oceanographic processes. Significant resources are currently being directed toward developing mathematical models of physical oceanographic processes with the goals of better understanding the role that the Southern Ocean plays in global climate processes, predicting the responses of ocean and global scale processes to climate change, and understanding the linkages between physical and biological oceanographic processes. These efforts have been limited by the scarcity of oceanographic data in the region, especially at high latitudes in the winter months. This study will provide new and significant oceanographic data on temperature and salinity profiles in to further the understanding of the dynamics of the upper water column of west Antarctic Peninsula continental shelf waters.
