Spatial familial networks to infer demographic structure of wild populations

recommendations! Published in 2021 at "Ecology and Evolution"

DOI: 10.1002/ece3.7345

Abstract: Abstract In social species, reproductive success and rates of dispersal vary among individuals resulting in spatially structured populations. Network analyses of familial relationships may provide insights on how these parameters influence population‐level demographic patterns. These… read more here.

DOI: 10.1002/ece3.8695

Abstract: Abstract Forest logging has contributed to the decline of several woodland caribou populations by causing the fragmentation of mature coniferous stands. Such habitat alterations could be worsened by spruce budworm (SBW) outbreaks. Using 6201 vegetation… read more here.

recommendations! Published in 2022 at "Ecology and Evolution"

DOI: 10.1002/ece3.8742

Abstract: Abstract Documenting trophic niche partitioning and resource use within a community is critical to evaluate underlying mechanisms of coexistence, competition, or predation. Detailed knowledge about foraging is essential as it may influence the vital rates,… read more here.

recommendations! Published in 2017 at "Ecosphere"

DOI: 10.1002/ecs2.1970

Abstract: Woodland caribou (Rangifer tarandus) are declining throughout much of their North American range. In Alberta, industrial development is the major driver for the disturbance to caribou habitat and ecosystem dynamics involving the invasion of other… read more here.

recommendations! Published in 2017 at "Journal of Wildlife Management"

DOI: 10.1002/jwmg.21209

Abstract: Understanding the limiting factors of a prey population is important before and during predator control programs, and optimal intensive management of an increasing prey population requires formal recognition of a sustainable population size. The migratory… read more here.

recommendations! Published in 2017 at "Journal of Wildlife Management"

DOI: 10.1002/jwmg.21288

Abstract: Disturbance by anthropogenic activities may cause chronic (long-term) stress in wildlife and contribute to population declines. Although declines of boreal woodland caribou (Rangifer tarandus caribou) across Canada have been attributed to anthropogenic disturbance, the physiological… read more here.

DOI: 10.1007/s10592-024-01612-y

Abstract: Better knowledge of genetic relationships between the Fortymile caribou herd and its neighbors is needed for conservation decision-making in Canada. Here, we contribute the first fine-scale analysis of genetic population structure in nine contiguous caribou… read more here.

DOI: 10.1007/s10980-024-01882-4

Abstract: Large-scale natural disturbances are crucial drivers of ecosystem function and composition for many forested ecosystems. In the last century, the prevalence of anthropogenic disturbances has increased across Canada’s boreal forest. Habitat disturbance from timber harvest… read more here.

recommendations! Published in 2018 at "Biological Conservation"

DOI: 10.1016/j.biocon.2018.09.015

Abstract: Abstract Management of wildlife often relies upon understanding mechanisms linking anthropogenic disturbance to population declines. The most-cited mechanism by which disturbance threatens boreal caribou (Rangifer tarandus caribou) is the exacerbation of apparent competition via increases… read more here.

DOI: 10.1016/j.jenvman.2018.03.039

Abstract: Tradeoffs between cost and recovery targets for boreal caribou herds, threatened species in Alberta, Canada, are examined using a dynamic cost minimization model. Unlike most approaches used for minimizing costs of achieving threatened species targets,… read more here.
