As top predators, leopard seals play a disproportionately large role in ecosystem functioning and act as sentinel species that can track habitat changes. How leopard seals respond to a warming environment depends on their adaptive capacity, that is a 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. Investigating the adaptability of Antarctic biota in a changing system aligns with NSF\u2019s Strategic Vision for Investments in Antarctic and Southern Ocean Research. This research, which is tightly integrated with educational and outreach activities, will increase diversity in STEM and Antarctic science by recruiting students from historically underrepresented groups in STEM and providing training, mentoring, and educational opportunities at an emerging Hispanic Serving Institution and a Historically Black Colleges and Universities campus. This project will improve STEM education and science literacy via museum collaborations, creation of informational videos and original artwork depicting the research. The proposal supports data and sample reuse in polar research and long-term reuse of scientific data, thereby maximizing NSF\u2019s investment in previous field research and reducing operational costs. The researchers will investigate leopard seals adaptive capacity to the warming Southern Ocean by quantifying their ability to move (dispersal ability), adapt (genetic diversity), and change (plasticity). Aim 1 of the research will determine leopard seals\u2019 dispersal ability by assessing their distribution and movement patterns. Aim 2 will quantify genetic diversity by analyzing genetic variability and population structure and Aim 3 will examine phenotypic plasticity by evaluating changes in their ecological niche and physiological responses. The international, multidisciplinary team will analyze existing data (e.g., photographs, census data, life history data, tissue samples, body morphometrics) collected from leopard seals across the Southern Ocean over the last decade. Additionally, land- and ship-based field efforts will generate comparable data from unsampled regions in the Southern Ocean. The research project will analyze these historical and contemporary datasets to evaluate the adaptive capacity of leopard seals against the rapidly warming Southern Ocean. This research is significant because changes in the distribution, genetic diversity, and ecophysiology of leopard seals can dramatically restructure polar and subpolar communities. Further, the research will expand understanding of leopard seals\u2019 ecological role, likely characterizing the species as flexible polar and subpolar predators throughout the Southern Hemisphere. The findings of this research will be relevant for use in ecosystem-based management decisions\u2014including the design of Marine Protected Areas\u2014 across three continents. This study will highlight intrinsic traits that determine species\u2019 adaptive capacity, as well as showcase the dynamic links between polar and subpolar ecosystems.

In a study of Adelie penguins that spans 13 breeding seasons, results indicate that only 20% of individuals within a colony successfully raise offspring, and that they do so because of their exemplary foraging proficiency. Moreover, foraging appears to require more effort at the largest colony, where intraspecific competition is higher than at small colonies, and also requires more proficiency during periods of environmental stress. When conditions are particularly daunting, emigration dramatically increases, countering the long-standing assumption that Ad\u00e9lie penguins are highly philopatric.

Understanding their physiological ecology is essential to the assessment of their adaptability to the threats of climate change, pollution, and overfishing. The proposed research has multipronged objectives. Prior results suggest that Emperor penguins have flexible (vs. static) aerobic dive limits (ADL) that vary with the type of dive, and that the role of heart rate in utilization of oxygen stores also varies with dive type. A series of physiological measurements are proposed with backpack electrocardiogram recorders, that will allow further delineation of patterns and interrelationships among heart rate, dive behavior, and oxygen stores. Importantly, the research will be done on free diving emperors, and not individuals confined to a dive hole, thereby providing a more genuine measure of diving physiology and behavior. A separate objective is to examine foraging behavior of leopard seals, using a backpack digital camera and time depth recorder. Leopard seal behavior and prey intake is poorly quantified, but known to be significant. Accordingly the research is somewhat exploratory but will provide important baseline data. Finally, the P.I. proposes to continue long term overflight censuses of Emperor penguin colonies in the Ross Sea. Broader impacts include collaboration with National Geographic television, graduate student training, and development of sedation techniques for leopard seals.", "east": 150.0, "geometry": "POINT(-25 -73)", "instruments": null, "is_usap_dc": true, "keywords": "Not provided", "locations": null, "north": -68.0, "nsf_funding_programs": "Antarctic Organisms and Ecosystems", "paleo_time": null, "persons": "Ponganis, Paul", "platforms": "Not provided", "repo": "USAP-DC", "repositories": "USAP-DC", "science_programs": null, "south": -78.0, "title": "The Physiological Ecology of Two Antarctic Icons: Emperor Penguins and Leopard Seals", "uid": "p0000349", "west": 160.0}]
