Research: Dietary differences among individuals with different genes and coat colours gives insight into the maintenance of the Spirit bears among black bear populations

Research: Dietary differences among individuals with different genes and coat colours gives insight into the maintenance of the Spirit bears among black bear populations

The paper, “Intrapopulation foraging niche variation between phenotypes and genotypes of Spirit bear populations,” was published in the open-access journal Ecology and Evolution.

Chinook salmon exhibit long-term rearing and early marine growth in the Fraser River, B.C., a large urban estuary

Chinook salmon exhibit long-term rearing and early marine growth in the Fraser River, B.C., a large urban estuary

Using tiny salmon ear bones, or otoliths, Raincoast researchers and partners were able to demonstrate that Chinook salmon from Harrison River rely on the Fraser estuary for one to two months while they feed and grow. These findings underscore the critical nature of this habitat for the persistence and recovery of Chinook salmon…

Research: Conservation in heavily urbanized biodiverse regions requires urgent management action and attention to governance

Research: Conservation in heavily urbanized biodiverse regions requires urgent management action and attention to governance

A new open access research paper led by Dr. Tara Martin at the UBC Conservation Decisions Lab applied a novel conservation decision making tool called Priority Threat Management to identify the most cost-effective management strategies needed to address the threats facing 102 species at risk identified in the area…

Research: Compliance of small vessels to minimum distance regulations for humpback and killer whales in the Salish Sea

Research: Compliance of small vessels to minimum distance regulations for humpback and killer whales in the Salish Sea

The rise of vessel traffic, the growth of the whale watching industry, increased interactions between whales and small vessels, and the precarious existence of Southern Residents in particular, has given rise to some regulations from the federal government that attempt to mitigate the harm these interactions pose…

Research: Addressing poor statistical support for wolf control and maternal penning as conservation measures for endangered mountain caribou

Research: Addressing poor statistical support for wolf control and maternal penning as conservation measures for endangered mountain caribou

A new study shows that while addressing potential threats from wolves does not seem to be effective, an important new signal has emerged from the data: ecotype.

Study: Spatial patterns and rarity of the white‐phased ‘Spirit bear’ allele reveal gaps in habitat protection

Study: Spatial patterns and rarity of the white‐phased ‘Spirit bear’ allele reveal gaps in habitat protection

New research has identified that the small genetic change responsible for Spirit bears – a rare, white-coated form of black bears – is up to 50% rarer in the Great Bear Rainforest than previously estimated. The study also indicates that geographic hotspots, where the Spirit bear version of the gene was especially prominent lack adequate protection from resource extraction…

On the risk of pathogens carried by hypermobile human predators

On the risk of pathogens carried by hypermobile human predators

In a recent commentary published in Nature Human Behaviour, “Hypermobile human predators,” Raincoast scientists Chris Darimont and Heather Bryan raise questions regarding potential differences between human hunters and other predators with respect to the potential for disease transmission in prey populations and point out a need for further research…

Ecology and Evolution: Functional response of wolves to human development across boreal North America

Ecology and Evolution: Functional response of wolves to human development across boreal North America

Previous research on how wolves are affected by human development have been limited in scope and location and the results were mixed. Wolves adapted in a range of ways depending on contextual factors like road or cutblock density. Research undertaken by a team of conservation scientists, including Paul Paquet of Raincoast Conservation Foundation, endeavoured to…
