Human predators outpace other agents of trait change in the wild
It is shown that average phenotypic changes in 40 human-harvested systems are much more rapid than changes reported in studies examining not only natural but also other human-driven perturbations in the wild, outpacing them by >300% and 50%, respectively.
Quantifying Inter- and Intra-Population Niche Variability Using Hierarchical Bayesian Stable Isotope Mixing Models
A hierarchical stable isotope mixing model is described that can simultaneously estimate both the prey composition of a consumer diet and the diet variability among individuals and across levels of population organization and shows support for extensive intra-population niche variability among Individuals, social groups, and geographically isolated subpopulations.
The unique ecology of human predators
It is suggested that humans function as an unsustainable “super predator,” which—unless additionally constrained by managers—will continue to alter ecological and evolutionary processes globally.
Landscape heterogeneity and marine subsidy generate extensive intrapopulation niche diversity in a large terrestrial vertebrate.
The results suggest that spatial heterogeneity and allochthonous subsidy--both widespread but commonly subject to contemporary anthropogenic change--might provide novel opportunities for examination and conservation of ecological variation within populations.
Toward increased engagement between academic and indigenous community partners in ecological research
Ecological research, especially work related to conservation and resource management, increasingly involves social dimensions. Concurrently, social systems, composed of human communities that have
The genetic legacy of extirpation and re-colonization in Vancouver Island wolves
Genetic data show that Vancouver Island wolves are distinct from dogs and thus should be recognized as a population of wild wolves, and suggest that the introgression took place due to the Allee effect, specifically a lack of mates when population size was low.
Wildlife conservation and animal welfare: two sides of the same coin?
Human activities deprive wild animals of their life requisites by destroying or impoverishing their surroundings, causing suffering of individuals. Yet, the notion that animal welfare applies to
Ecological factors drive differentiation in wolves from British Columbia
It is proposed that dispersing grey wolves select habitats similar to the one in which they were reared, and that this differentiation is maintained largely through behavioural mechanisms, suggesting that ecological factors are driving wolf differentiation in British Columbia.
Using Bayesian stable isotope mixing models to estimate wolf diet in a multi-prey ecosystem†
The results support suggestions of other researchers that species-specific fractionation values should be used whenever possible, and that SIA may sometimes only provide indices of use for general groups of prey (e.g., large ungulates).
Seasonal and biogeographical patterns of gastrointestinal parasites in large carnivores: wolves in a coastal archipelago
The first report of gastrointestinal parasites in gray wolves from the central and north coasts of British Columbia, Canada is provided, providing a unique, extensive and solid baseline for monitoring parasite community structure in relation to environmental change.
