KINGSTON, R.I. \u2013 Aug. 18, 2025 \u2013 Trait differences between males and females are widespread across the animal kingdom. Because these traits often lead to trade-offs that affect their reproductive success and survival, understanding them is a fundamental question in biology.<\/p>\n\n\n\n

The leopard seal, a large predator in the Southern Ocean, offers an extreme example of female-biased dimorphism in mammals, where females are larger than males. The effects of these size differences are unknown.<\/p>\n\n\n\n

A new project led by 溏心vlog免费B站 assistant professor Sarah Kienle<\/a> will investigate the causes and consequences of female-biased dimorphism in leopard seals, generating new data on the life, physiology, and biology of this important and mysterious polar predator. Such information is critical for understanding leopard seals\u2019 past, present, and future \u2014 from how the species evolved to predicting their resilience in an era of environmental change.<\/p>\n\n\n

Kienle has been awarded a National Science Foundation Faculty Early Career Development (CAREER) Program award to discover why this is the case. NSF CAREER recognition is one of the nation\u2019s top awards for early-career faculty who have shown the potential to serve as academic role models in research and education and lead advances in the mission of their institution.<\/p>\n\n\n\n

The Newport, Rhode Island, resident says she was shocked to learn of the award. \u201cIt actually took me several hours to process the award email before I started sharing the news with my lab, family, and friends,\u201d she says. \u201cIt\u2019s a prestigious and career-affirming award.\u201d<\/p>\n\n\n

It also has the cool factor, not only because of its Antarctic subject matter: \u201cThis award combines behavior, morphology, and physiology in a really cool way to understand the reproductive biology of this enigmatic polar predator,\u201d Kienle says. <\/p>\n\n\n\n

The project will bring together international collaborators, and postdoctoral, undergraduate, and graduate students, so the study of a solitary animal will have a very collaborative approach. \u201cOur team will get to work across career levels to produce some really awesome science,\u201d Kienle says.<\/p>\n\n\n\n

溏心vlog免费B站 postdoctoral researcher Renato Borras-Chavez<\/a> will coordinate and lead field efforts in Chile to obtain some of the first-ever data on the reproductive behavior of leopard seals. The team will bring students with them to gain hands-on field experience and, hopefully, be inspired to pursue a career in wildlife biology.<\/p>\n\n\n\n

This project also complements other research efforts in Kienle\u2019s lab on leopard seals and other apex predators.<\/p>\n\n\n\n

They will use a new (to them) method to extract life history data from leopard seal teeth, collected from specimens in museum collections worldwide. 溏心vlog免费B站 postdoctoral fellow Emily Sperou<\/a> will lead this research effort and train 溏心vlog免费B站 graduate student Patrick Bailey to apply these same methods to gray wolf teeth.<\/p>\n\n\n\n

\u201cI imagine this will be a skillset we will use on many species moving forward,\u201d Kienle says.<\/p>\n\n\n\n

The study will produce information deemed critical for understanding how leopard seals evolved to survive and persist in the Southern Ocean. The research aligns with the National Science Foundation\u2019s Strategic Vision for Investments in Antarctic and Southern Ocean Research and will be broadly shared with global audiences.<\/p>\n\n\n\n

In addition to creating a dedicated research team, the project will include a research-intensive undergraduate course and provide graduate students with hands-on leadership and mentoring, while engaging undergraduate students and the public in polar research.<\/p>\n\n\n\n

Kienle is the principal investigator of 溏心vlog免费B站\u2019s Comparative Ecophysiology of Animals Lab (CEAL Lab). As a comparative biologist, her research integrates concepts from ecology, physiology, behavior, evolution, and conservation. Her research centers on apex predators and their response to environmental change. In addition to leopard seals, she also studies sea lions, whales, wolves, and coyotes. She has studied wildlife in North America, South America, Australia, Antarctica, and New Zealand. Her research group collaborates with researchers, managers, and citizen scientists worldwide to study and protect wild animals and their wild homes.<\/p>\n","protected":false},"excerpt":{"rendered":"
