Greetings MARMAM!

Join us on *15 April 2021 at 5 PM Pacific Time (1 AM UTC)* for the next SMM
Seminar Editor's Select Series: *What Does It Take To Power A Walrus?
Predicting the Effect of Climate Change on Food Requirements of an Iconic
Arctic Species*

*The SMM Seminar Editor's Select Series highlights the latest and most
exciting marine mammal science published in the Marine Mammal Science
Journal. This is your chance to engage with marine mammal scientists, learn
and ask questions from anywhere in the world. All are welcome.*

*About this talk:*
Climate change is rapidly altering the Arctic ecosystem, including dramatic
decreases in the extent of summer ice. Scientists are trying to predict the
effect of these environmental transformations on wildlife. This includes
the Walrus, an iconic, ice-dependent species that relies on stable ice
surfaces to rest and act as a base for foraging on nearby food beds.
Mathematical bioenergetic models are a typical tool that scientists use to
predict the food energy requirements of animals under different conditions,
and several such models have been constructed for walruses. However, these
models are only as accurate as the data that goes into them. This talk will
describe several studies that measured the costs of resting in water and
swimming in two juvenile walruses on loan to the Vancouver Aquarium. I will
describe what it was like to work with these boisterous, large animals on a
daily basis, the scientific challenges and opportunities they provided, and
what the resulting data tells scientists about the costs of global warming
on these animals.

*About the Presenter:*
Dr. David Rosen is Assistant Professor at the University of British
Columbia. His current research primarily investigates the bioenergetics
(energy requirements and expenditures) of marine mammals. Its focus is to
understand the root causes of population changes by investigating the
interactions between the physiology of individual animals and biotic and
abiotic environmental changes. The work directly contributes to the
conservation and management of marine resources, particularly those in
Arctic regions, where environmental change – including climate change and
fisheries impacts – is most evident.

*The event is f*ree to attend online on Zoom. Registration is required.
