Long-term studies quantify the prey requirements of pinnipeds, and help predict the effects of nutritional stress
Two new studies by Dr. David Rosen answer the question: “How much fish does a seal need?”
Food for seals and other Arctic predators is shrinking — literally
Unchecked climate change may leave some Arctic predators, such as seals and whales, surviving off of marine “junk food”.
PROFILE: Using mathematical ingenuity to solve ecological puzzles
“Ecology has a lot of difficult data to handle, and a big part of my research is developing new statistical methods to tackle these problems,” says Dr. Marie Auger-Méthé.
Guadalupe fur seals continue to recover as new colony discovered
New colony of Guadalupe fur seals discovered on El Farallón de San Ignacio Island, Gulf of California
Harbour seals respond differently to pulses of out-migrating coho and Chinook salmon smolts
UBC researchers set out to determine who was eating juvenile salmon, and when and where it was occurring by capturing and tracking harbour seals that carried cell-phone-like devices that recorded everything and everywhere the seals went.
SPOTLIGHT: Marine Mammal Energetics and Nutrition Lab carries on with research despite COVID-19 setbacks
“It just means we have to be creative to keep research going,” said David Rosen, assistant professor and principal investigator
It’s a drag wearing a tag
What impacts do tracking tags have on the behavior and swimming costs of marine mammals?
Open Water Research Station contributes a decade of discoveries
This year marks the ten-year anniversary of the MMRU Open Water Research Station, a floating laboratory at the centre of a ground-breaking scientific collaboration that has significantly advanced understanding of how nutritionally stressed Steller sea lions forage in the wild.
Harbor seal dietary insights gained through new DNA technique
A promising new technique called DNA metabarcoding, can be used to identify specific marker genes in seal droppings.
