Are We Capturing Faunal Intactness A Comparison of Intact Forest Landscapes and the Last of the Wild in Each Ecoregion

By examining overlap between areas that are least impacted by human disturbance, and species abundance the authors show that 54.7% of the terrestrial realm (excluding Antarctica) has at least one species recorded as extinct and that two thirds of intact areas overlap with areas where species have gone extinct in the past 500 years. Even within the most remote areas, serious faunal loss has taken place.

Underwater noise in the Arctic - A state of knowledge report

A review of the current state of knowledge as a baseline for our understanding of underwater noise in the Arctic Ocean,including ambient sound levels, underwater noise created by anthropogenic activities, and impacts of underwater noise on marine life, including marine mammals, fish, and invertebrates.

Bat activity and richness in beetle-killed forests in southern British Columbia

Large ares of forest in western North America are characterized by dead trees caused by outbreaks of bark beetles in the past decades. Uncertain of how patches of dead trees may effect bat populations, the researchers conducted surveys of bat species richness in forests with low and high levels of tree deaths. They detected 6 species of bats, including little brown bats that are listed as endangered by the federal government. They determined that beetle-killed forest do not effect bat presence nor activity and also do not provide increased habitat use for bats.

A boreal songbird's 20,000 km migration across North America and the Atlantic Ocean

Geolocation technology allowed researchers to track Blackpoll Warblers as they undertook their annual migration cycle. These 12 gram birds double their body weight before undertaking an astonishing journey, migrating over 3,000 km over the Atlantic Ocean to overwinter in South America before returning to breed. Blackpoll Warblers populations are declining and identifying key overwintering and breeding sites may be key to their survival. As a high-quality breeding site, the protection of Canada's boreal forest is critical to saving this amazing songbird

Mercury bioaccumulation in relation to changing physicochemical and ecological factors across a large and undisturbed boreal watershed

WCS researchers studied the cycling of mercury, a toxic metal in an undisturbed boreal watershed to better understand how future development may influence its behaviour. They determined that the concentration of mercury is influenced by physical and chemical attributes of water systems, including nitrogen and oxygen concentrations.

Food web rewiring in a changing world

As climate change creates climatic heterogeneity across landscapes, the authors hypothesize that generalist consumers will respond by adapting their behaviour to the environment and alter food webs in predictable ways. Using existing data from diverse ecosystems, the researchers show that this behavioural modification by generalist consumers alter food web dynamics in two ways: 1) They feed in new areas where they previously didn't, or on new prey, and alter food web connections; and 2) they alter food web interaction strengths by changing their relative use of differentially altered habitats, causing changes in energy and carbon flows. By finding shared, altered behaviour in species that share traits, the authors argue that we can better understand shifting food web dynamics, and use this tool to better predict the impacts of climate change.

Life at the top. Lake ecotype influences the foraging pattern, metabolic costs and life history of an apex fish predator

Using acoustic telemetry data and acceleration sensors, the authors compared the metabolic costs of lake trout between four populations in lakes with varying types of prey. They determined that lake trout feeding behaviour was characterized by clearly delineated periods of active hunting and rest. Populations with prey that were smaller or more difficult to catch had fewer resting periods and expended more energy during active periods.

Population genetics reveal Myotis keenii (Keen's myotis) and Myotis evotis (long-eared myotis) to be a single species

Assessing vessel slowdown as an option for reducing acoustic masking for Arctic cod in the western Canadian Arctic

Underwater sound generated from vessel traffic can negatively effect wildlife by making it difficult for them to hear biologically-important sounds. Where it isn't possible to reroute traffic, slowing down vessel travel speed may mitigate the impacts of sound. The researchers investigated how a speed reduction from 25 to 15 knots effecting the listening ability of fish. They determined that the most important factors when mitigating sound pollution was the type of vessel, and distance of the vessel from the animals, rather than speed.

Seasonal patterns in marine mammal vocalizations in the western Canadian Arctic

WCS researchers and colleagues used acoustic monitoring to monitor marine mammal populations at two sites in the Arctic: Sachs Harbour and Ulukhaktok, Northwest Territories, Canada. Their research revealed the presence of beluga and bowhead whales during the ice-free season, bearded seals through the ice-covered and mating seasons, and ringed seals year round. The presence of these species, and differences in the timing of species presence between the two sites, serve as baseline data for future monitoring in the region.
