Seals have a superpower: they are the only mammals with amphibious hearing! They hear well both in-air and underwater. My collagues and I have a new study in Proceedings B on the origins and evolution of amphibious hearing in pinnipeds 🦭🔊🧪 doi.org/10.1098/rspb...

Join Mia Wege and me to study niche partitioning among three Antarctic mesopredators! Fully-funded PhD opportunity at U Canterbury, please email michelle.larue@canterbury.ac.nz if you're interested! Applications will be reviewed until filled.
Fluffy Weddell seal pup looks straight into the cameraWe are seeking a motivated PhD student to investigate how multiple mesopredators share space and resources in the Southern Ross Sea. The project will address questions about niche partitioning (both spatial and temporal) and foraging ecology in the Southern Ocean using three years of animal tracking data deployed on penguins (n = 60) and seals (n = 30). Specifically, we wish to uncover aspects of three-dimensional space use in Adélie penguins, emperor penguins, and Weddell seals at Cape Crozier, in the southern Ross Sea. There exists one of the largest colonies of Adélie penguins, a small colony of emperor penguins, and a small group of Weddell seals. We ask: How are these animals using the same space at the same time? How can that part of the ocean support hundreds of thousands of central-place foragers in a relatively small foraging halo, during the short summer window of time? Answers to these questions will provide fine-scale insights as part of the larger project which seeks to understand the metacommunity structure of marine mesopredators in the Southern Ocean and will inform conservation in the Ross Sea Marine Protected Area (one of the largest in the world). With the first 10-year evaluation of the MPA coming up, this project will have immediate real-world impact.
We cannot guarantee Antarctic field work as part of the PhD project.
Funding: Rutherford Discovery Fellowship ($27,000 NZD/year for three years + fees), plus potential school-supported (School of Earth and Environment) conference travel opportunities.
Requirements: Bachelor’s and Master’s degree in Ecology, Marine Biology, Geography, Zoology or Statistics required; good communication skills (written and verbal), with previous publication experience a bonus; strong work ethic, strong initiative, and team attitude; previous experience handling biologging data (in any system), large datasets, and data wrangling a plus.
