Drivers and consequences of individual specialization in an Arctic marine top predator

inist — Sun, 16 Jul 2023 07:15:00 +0000

Principal Investigator: Gregory Thiemann Funding: NSERC Discovery Grant. Term: 2021-2026. The proposed research involves testing hypotheses around the environmental drivers and ecological consequences of individual specialization, using the polar bear (Ursus maritimus) as a model species and target for conservation. As a long-lived top predator in a dynamic habitat, polar bears demonstrate several characteristics that […]

Conserve and sustainably use the oceans, seas and marine resources for sustainable development. Oceans are essential to human life on Earth; they provide us with food and water, and regulate the planet’s weather. SDG 14 seeks to keep our oceans and coastlines healthy for all living beings who rely on them by reducing pollution and […]

Assessing the Holocene paleoenvironmental history of Lake Scugog

patilpos — Mon, 26 Sep 2022 18:41:00 +0000

by Randelle Adano Lake Scugog is a large, shallow reservoir in southern Ontario that has faced multiple stressors like climate change, eutrophication, and invasive species over the post-industrial period. The arrival of the first, early settlers in ~1700 has brought significant infrastructure development in the area, most notably the building of the Lindsay Dam in […]

Ontario's cormorant hunt and what it means for its future

patilpos — Mon, 06 Jun 2022 12:59:00 +0000

by Gail Fraser For the last 14 years, I’ve studied double-crested cormorants at Tommy Thompson Park on the east side of Toronto’s harbour. Every April, I put on my coveralls and venture forth to follow a sample of nests, recording when nesting began and whether birds were successful at raising young. My goal is to […]

Knowledge co-production to address human-polar bear conflict in Southern Hudson Bay and James Bay

paultran — Mon, 14 Mar 2022 20:08:00 +0000

Polar bears in Ontario are at the southern limit of their species’ range. As part of the Southern Hudson Bay subpopulation, these roughly 800 bears migrate onto land when the sea ice of Hudson Bay melts completely each summer. On shore, polar bears primarily fast and rely on stored fat for energy. With increasing global […]

Climate change and differing lake characteristic's impact on cyanobacteria bloom formation in oligotrophic systems

paultran — Fri, 21 Jan 2022 03:36:30 +0000

Cyanobacteria, commonly referred to as Blue-Green Algae, are a ubiquitous photosynthetic bacteria that under the right conditions – high light, warm temperatures, high nutrient concentrations, high thermal stability, low surficial sediment redox– cyanobacteria are able to rapidly proliferate, forming dense populations or blooms (often creating dense mats on the water surface). Freshwater blooms are detrimental […]

Polar bear diets reflect environmental changes

paultran — Tue, 02 Nov 2021 16:00:40 +0000

When people hear the words “global warming,” they often think of the polar ice caps melting, and the polar bears that suffer as a result. This raises questions about how rising temperatures and sea ice loss are affecting the diets of polar bears, and how this information can be used to help protect them. New research from […]
