Field update: Argentina, December 2024 – January 2025

This field season is the first time we’ve been at Punta Tombo, Argentina persistently from October to March since before the pandemic! We’ve seen chicks hatch and watched them grow into chubby fledglings. Unfortunately many died in December with their bellies full; we suspect it was due to toxic algae, which could also be the cause of the 71 southern […]

Plasticity syndromes in wild vertebrates: Patterns and consequences of individual variation in plasticity across multiple behaviours

From abstract:“Using a 40-year dataset on free-ranging Magellanic penguins, we find evidence of both positively and negatively correlated behavioural plasticities. Plasticity did not strongly affect lifetime reproductive success, but its effect on interannual performance varied significantly by environmental context: plasticity reduced success in average oceanic conditions, increased success in anomalously productive conditions and, contrary to expectation, did not buffer against

Ship collision risk threatens whales across the world’s oceans

Excerpt from UW News: “Thousands of whales are injured or killed each year after being struck by ships, particularly the large container vessels that ferry 80% of the world’s traded goods across the oceans. Collisions are the leading cause of death worldwide for large whale species. Yet global data on ship strikes of whales are hard to come by —

Removing institutional barriers to long-term fieldwork is critical for advancing ecology

Abstract: Long-term fieldwork is essential for ecology and conservation, but is hindered by institutional barriers, such as the publish-or-perish culture of academia, and funding limitations. Here, we discuss these challenges and propose strategies to overcome them, such as broadening evaluation metrics and supporting inclusivity, to advance scientific insight and societal equity. Authors: Kasim Rafiq, Neil R. Jordan, Weldon McNutt, John

Maximizing biological insights from instruments attached to animals

From the highlights section: “Biologging sensors enable broad-scale, high-resolution measurements of the physiological, behavioral, demographic, social, and environmental interactions underpinning patterns in nature. We present a framework, case studies, and outstanding questions for integrating biologging data with theoretical concepts to facilitate process explanation and prediction.” Authors: Roxanne S. Beltran, A. Marm Kilpatrick, Simona Picardi, Briana Abrahms, Gabriel M. Barrile, William

Foot darkening with age in Spheniscus penguins: applications and functions

From the abstract: “We found that Spheniscus penguins have pale feet at hatching and the feet become darker with age throughout the lives of individuals. We showed that we can accurately predict the age structure of a colony of Magellanic penguins Spheniscus magellanicus, but not the ages of individual penguins, based on a sample of foot colors.” Authors: Ginger Rebstock,

Field Updates: Botswana, summer 2024

Written by Dr. Kasim Rafiq In June 2024, postdoctoral researcher Dr. Kasim Rafiq and PhD candidate Leigh West from Dr. Briana Abrahms‘ lab returned to Wild Dog Camp in the Okavango Delta and were joined by Briana’s new PhD student Marie-Pier Poulin. The team successfully deployed six new tracking collars on African wild dogs, including in two brand new packs,

Abrahms Lab grad student Leigh West publishes first article

Congratulations to Leigh West, Dr. Abrahms’s graduate student, who just recently published her first paper as lead author. Her research article, “Droughts reshape apex predator space use and intraguild overlap,” was published in the Journal of Animal Ecology on October 4th, and also serves as the second chapter of her dissertation. This is an exciting milestone for Leigh as she
