Dr. Caroline Cappello
I graduated from Brandeis University with a bachelor’s degree in environmental studies and theater arts (though haven’t yet found a way to combine the two!). My focus on wildlife ecology and conservation as an undergraduate provided the opportunity to study large mammal ecology in Tanzania and Kenya. After graduating and before joining the Boersma Lab, I wandered the country as a seasonal field biologist, working with a variety of birds and mammals. Some highlights from those nomadic years include recording elk behavior in Oregon, mist-netting yellow-billed cuckoos in the Sonoran Desert, tracking American martens through snowy Wisconsin forests, and managing breeding piping plover and least tern populations along the coast of southern Maine.
I am interested in the ability of species to persist in a changing environment. Specifically, I am interested in the factors that drive the timing of key life events like reproduction and migration, the capacity of individuals to shift their phenology in response to environmental change, and the implications of phenological shifts for populations. In the Boersma lab, I consider this topic in two systems:
Phenological shifts in seabird reproduction – Punta Tombo, Argentina–
Breeding at Punta Tombo, the world’s once-largest Magellanic penguin colony, is later and less synchronous than in the early 1980s. By combining the Boersma Lab’s 35-year ecological dataset with remotely sensed oceanographic data, I am exploring the implications of these phenological shifts on reproductive success, chick growth, and recruitment.
Breeding biology and conservation of an endangered seabird – Galápagos Islands, Ecuador–
The Galápagos penguin is a rare seabird that, unlike many penguin species, does not nest colonially. Locating these birds and understanding their natural history and population dynamics is a challenge. Along with Dee Boersma and Godfrey Merlen, I aim to understand the drivers of reproduction (e.g. nest-site availability, oceanographic conditions) and survival for the Galápagos penguin and to provide information to Galápagos National Park that will aid them in the management of this small, endangered population.
