Carnivore resource subsidies to support predator reintroductions and mitigate threats to reintroduced prey

The Journal of Wildlife Management, EarlyView.
Supplementary feeding of reintroduced carnivores is a tool that may increase translocation success and ease predation pressure on prey populations at critical times. In this study, we monitored the activity of native prey, and the activity and diet of a reintroduced predator, the western quoll (Dasyurus geoffroii), around carcass feeding stations in an

Mixed evidence for disturbance‐mediated apparent competition for declining caribou in western British Columbia, Canada

The Journal of Wildlife Management, EarlyView.
Investigating the decline of a caribou population in central British Columbia, we found that 1) recent wildfires were a stronger draw for primary ungulate prey than cutblocks, 2) most predators were associated with primary prey but had mixed responses to disturbance, and 3) caribou used cutblocks, potentially increasing their risk.

Mapping interactions between winter recreationists and an endangered ungulate

The Journal of Wildlife Management, EarlyView.
Southern mountain caribou are a federally designated species at risk, with declines occurring throughout their range. This species overlaps spatially and temporally in their late‐winter habitats with heli‐skiing, an activity that relies on helicopters to transport skiers to remote mountainous locales.

Heavy Metal Contamination in Arenillas Ecological Reserve Soils: Correlation and Conservation Impact

Land Degradation &Development, EarlyView.
ABSTRACT This study addresses the critical knowledge gap regarding heavy metal contamination in the soils of the Arenillas Ecological Reserve (AERv), located on the southwest coast of Ecuador. Despite being a fragile and highly biodiverse ecosystem, little is known about the magnitude, spatial distribution, and drivers of heavy metal contamination in ...

Algal food identity affects morphological anti‐predatory defense in Daphnia pulex

Limnology and Oceanography, EarlyView.
Abstract Microcrustaceans of the genus Daphnia have evolved various inducible anti‐predator defenses; however, it is largely underexplored how the bottom‐up factor food quality may affect the extent of these defenses. A well‐studied example of an inducible defense is the deployment of neckteeth in Daphnia pulex in response to infochemicals from ...

Plankton communities today and tomorrow—potential impacts of multiple global change drivers and marine heatwaves

Limnology and Oceanography, EarlyView.
Abstract In the context of global change, marine organisms are subjected not only to gradual changes in abiotic parameters, but also to an increasing number of extreme events, such as heatwaves. However, we still know little about the influence of heatwaves on the structure of marine communities, and experimental studies are needed to test the impact ...

Increasing acidification does not affect sexual reproduction of a solitary zooxanthellate coral transplanted at a carbon dioxide vent

Limnology and Oceanography, EarlyView.
Abstract The absorption of atmospheric carbon dioxide is causing significant changes to the carbonate chemistry of the ocean, in a phenomenon called ocean acidification. The latter makes it potentially more difficult for marine calcifiers like corals, to build their calcium carbonate structures, thus affecting their ability to survive and reproduce ...
