Disturbance‐mediated changes to boreal mammal spatial networks in industrializing landscapes

Compound effects of anthropogenic disturbances on wildlife emerge through a complex network direct responses and species interactions. Land-use changes driven by energy forestry industries are known to disrupt predator-prey dynamics in boreal ecosystems, yet how these disturbance propagate across mammal communities remains uncertain. Using structural equation modeling, we tested disturbance-mediated pathways governing the spatial structure multipredator multiprey networks landscape-scale gradient within Canada's Athabasca oil sands region. Linear had pervasive effects, increasing site use for all focal species, except black bears threatened caribou, at least one landscape. Conversely, block (polygonal) were negative but less common. Indirect widespread mediated caribou avoidance wolves, tracking primary prey subordinate predators, intraguild dependencies among predators large prey. Context-dependent linear most common landscape with intermediate disturbance. Our research suggests that industrial directly affect suite mammals altering forage availability movement, leading indirect range interacting prey, including keystone snowshoe hare. The complexity network-level reinforces calls increased investment addressing habitat degradation as root cause declines broader ecosystem change.

Shifts in diel activity of Rocky Mountain mammal communities in response to anthropogenic disturbance and sympatric invasive white-tailed deer

Coexistence mechanisms such as temporal niche partitioning among sympatric wildlife species may be impacted by continued human disturbance and invasive species. White-tailed deer expansion in North America, a product of landscape climate change, alter other species' diel activity have implications for conservation native We asked: 1) To what degree does white-tailed overlap with ungulate (mule moose) landscapes high disturbance, versus low disturbance? 2) predator (wolves, grizzly bears, coyotes) Using detection data from infrared remote cameras, we compared high-disturbance (2019–2020) low-disturbance (2009–2010) the Canadian Rocky Mountains. used pattern analysis to quantify between mammal deer. found that contrary our hypotheses, maintained both landscapes. Predators did not match closely landscape. conjecture ungulates prioritizing periods optimal foraging or reducing predation risk rather than invasive-white-tailed Predator more sensitive anthropogenic adjust their Native ungulates' lack adaptation invasions is an important piece behavioural puzzle about how western Nearctic systems change human-mediated range shifts.

Indigenous-Led Conservation Reading List

Опубликована: Ноя. 1, 2021

This list compiles literature relevant to the bourgeoning Indigenous-led conservation movement, be that through Indigenous Protected and Conserved Areas (IPCAs, Canada), Community (ICCAs, global), or various other forms of governance co-governance mechanisms elevate rights, responsibilities, legal traditions. The introductory Colonial Conservation section is not exhaustive, but rather provides context for main import collection, which highlight possibilities, successes, challenges associated with decolonizing governance. global in scope has been shaped by Circle Experts’ (2018) report, We Rise Together, recommendations facilitating IPCAs Canada. majority pieces are peer-reviewed, however some print media also included.
