New research shows the influence of salmon abundance on the movement of bald eagles
The effect of salmon carcass availability on eagle distribution across multiple rivers was previously not well understood.
They’re everywhere: research finds polyester fibres throughout the Arctic Ocean
The presence of microplastics raises concerns that textiles, laundry and municipal wastewater may be an important source of these emerging pollutants.
Quantifying lost habitat for Pacific salmon in the Lower Fraser
Salmon have lost access to as much as 85 per cent of their historical floodplain habitat – the biologically rich wetlands next to a river or stream that typically harbour wildlife – due to dikes and similar infrastructure.
Research: Fisheries management of the Wuikinuxv bear-salmon-human system guided by n̓àn̓akila and data
Guided by the Wuikinuxv principle of n̓àn̓akila (to keep an eye on something or someone; a protector or guardian), a new study shows how fisheries managers can allocate salmon for wildlife, while balancing the needs of local communities.
Spatial alignment between grizzly bear genetic groups and Indigenous language families in coastal BC
In the landscape on the central coast of what is now known as British Columbia, genetic analyses have identified three distinct genetic groups of grizzly bears. The spatial areas of these groups align strikingly well with the geographies of three Indigenous language families (Tsimshian, Northern Wakashan, Salishan Nuxalk). The explanation the research partnership favours is…
Recommendations towards greater transparency in the science, science communication, and values-driven processes of natural resource management
A new paper, published by a team of researchers including Raincoast scientists, dives into the tangle of cognitive bias, institutional agendas, human interests, and pays special attention to the role of undisclosed value judgments.
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.
Research: The eroding social license to hunt carnivores
A new study suggests killing predators like wolves, grizzly bears, and cougars for trophy is a potential threat not only to these sensitive animals, but also to other hunters…
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
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
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
The scientists looked closely at the data provided in a previous study that examined how 18 caribou populations responded to different treatments including wolf culls, maternal penning, moose reduction, and combinations thereof, as well as controls. There were important errors in the statistical methods associated with that prior study…
