Do beluga whales truly migrate? Testing a key trait of the classical migration syndrome

Autor: Luke Storrie, Lisa L. Loseto, Emma L. Sutherland, Shannon A. MacPhee, Greg O’Corry-Crowe, Nigel E. Hussey

Publikováno v: Movement Ecology, Vol 11, Iss 1, Pp 1-13 (2023)

Abstract Background Migration enables organisms to access resources in separate regions that have predictable but asynchronous spatiotemporal variability in habitat quality. The classical migration syndrome is defined by key traits including directio

A meta-collection of nitrogen stable isotope data measured in Arctic marine organisms from the Canadian Beaufort Sea, 1983–2013

Autor: Ashley Ehrman, Carie Hoover, Carolina Giraldo, Shannon A. MacPhee, Jasmine Brewster, Christine Michel, James D. Reist, Michael Power, Heidi Swanson, Andrea Niemi, Wojciech Walkusz, Lisa Loseto

Publikováno v: BMC Research Notes, Vol 14, Iss 1, Pp 1-3 (2021)

Abstract Objectives Existing information on Arctic marine food web structure is fragmented. Integrating data across research programs is an important strategy for building a baseline understanding of food web structure and function in many Arctic reg

The summer soundscape of a shallow-water estuary used by beluga whales in the western Canadian Arctic

Autor: William D. Halliday, Kevin Scharffenberg, Dustin Whalen, Shannon A. MacPhee, Lisa L. Loseto, Stephen J. Insley

Publikováno v: Arctic Science, Vol 6, Iss 4, Pp 361-383 (2020)

The soundscape is an important habitat component for marine animals. In the Arctic, marine conditions are changing rapidly due to sea ice loss and increased anthropogenic activities such as shipping, which will influence the soundscape. Here, we asse

Oceanographic, ecological, and socio-economic impacts of an unusual summer storm in the Mackenzie Estuary

Autor: Kevin C. Scharffenberg, Dustin Whalen, Shannon A. MacPhee, Marianne Marcoux, John Iacozza, Gail Davoren, Lisa L. Loseto

Publikováno v: Arctic Science, Vol 6, Iss 2, Pp 62-76 (2020)

With increased warming and open water due to climate change, the frequency and intensity of storm surges is expected to increase. Although studies have shown that strong storms can negatively impact Arctic ecosystems, the impact of storms on Arctic m

Year-Round Dive Characteristics of Male Beluga Whales From the Eastern Beaufort Sea Population Indicate Seasonal Shifts in Foraging Strategies

Autor: Luke Storrie, Nigel E. Hussey, Shannon A. MacPhee, Greg O’Corry-Crowe, John Iacozza, David G. Barber, Alex Nunes, Lisa L. Loseto

Publikováno v: Frontiers in Marine Science, Vol 8 (2022)

Dive behavior represents multiple ecological functions for marine mammals, but our understanding of dive characteristics is typically limited by the resolution or longevity of tagging studies. Knowledge on the time-depth structures of dives can provi

Diet and feeding observations from an unusual beluga harvest in 2014 near Ulukhaktok, Northwest Territories, Canada

Autor: Lisa L. Loseto, Jasmine D. Brewster, Sonja K. Ostertag, Kathleen Snow, Shannon A. MacPhee, Darcy G. McNicholl, Emily S. Choy, Carolina Giraldo, Claire A. Hornby

Publikováno v: Arctic Science, Vol 4, Iss 3, Pp 421-431 (2018)

The Eastern Beaufort Sea (EBS) beluga (Delphinapterus leucas) population are an important traditional food for the Inuit of the Inuvialuit Settlement Region, Northwest Territories (NT) Canada. In 2014, over 30 beluga whales were harvested at Ulukhakt

Upriver sightings of beluga whales (Delphinapterus leucas) follow storm surges and high water in the Mackenzie Delta, Northwest Territories, Canada

Autor: Lisa L. Loseto, Kevin Scharffenberg, Shannon A. MacPhee

Publikováno v: Arctic Science. 7:679-689

Each summer, Eastern Beaufort Sea beluga whales (Delphinapterus leucas (Pallas, 1776)) form a large congregation in the Tarium Niryutait Marine Protected Area (TNMPA) in the Mackenzie River estuary, a behaviour thought to be linked to warm, freshwate

The Canadian Beaufort Shelf trophic structure: evaluating an ecosystem modelling approach by comparison with observed stable isotopic structure

Autor: Heidi K. Swanson, Michael Power, Karyn D. Suchy, Jasmine D. Brewster, J. D. Reist, Ashley D. Ehrman, Carolina Giraldo, Carie Hoover, Lisa L. Loseto, Shannon A. MacPhee

Publikováno v: Arctic Science (2368-7460) (Canadian Science Publishing), 2022-03, Vol. 8, N. 1, P. 292-312

Climate-driven impacts on marine trophic pathways worldwide are compounded by sea-ice loss at northern latitudes. For the Arctic, current information describing food-web linkages is fragmented, and there is a need for tools that can describe overarch
