Salmonid Species Diversity Predicts Salmon Consumption By Terrestrial Wildlife, Christina N. Service, Andrew N. Bateman, Megan S. Adams, Kyle A. Artelle, Thomas E. Reimchen, Paul C. Paquet, Chris T. Darimont
Salmonid Species Diversity Predicts Salmon Consumption By Terrestrial Wildlife, Christina N. Service, Andrew N. Bateman, Megan S. Adams, Kyle A. Artelle, Thomas E. Reimchen, Paul C. Paquet, Chris T. Darimont

1. Resource waves—spatial variation in resource phenology that extends feeding opportunities for mobile consumers—can affect the behaviour and productivity of recipient populations. Interspecific diversity among Pacific salmon species (Oncorhynchus spp.) creates staggered spawning events across space and time, thereby prolonging availability to terrestrial wildlife.
2. We sought to understand how such variation might influence consumption by terrestrial predators compared with resource abundance and intra- and interspecific competition.
3. Using stable isotope analysis, we investigated how the proportion of salmon in the annual diet of male black bears (Ursus americanus; n = 405) varies with species diversity and density of spawning …
Publication Reform To Safeguard Wildlife From Researcher Harm, Kate A. Field, Paul C. Paquet, Kyle A. Artelle, Gilbert Proulx, Ryan K. Brook, Chris T. Darimont
Publication Reform To Safeguard Wildlife From Researcher Harm, Kate A. Field, Paul C. Paquet, Kyle A. Artelle, Gilbert Proulx, Ryan K. Brook, Chris T. Darimont
Chris Darimont, PhD
Despite abundant focus on responsible care of laboratory animals, we argue that inattention to the maltreatment of wildlife constitutes an ethical blind spot in contemporary animal research. We begin by reviewing significant shortcomings in legal and institutional oversight, arguing for the relatively rapid and transformational potential of editorial oversight at journals in preventing harm to vertebrates studied in the field and outside the direct supervision of institutions. Straightforward changes to animal care policies in journals, which our analysis of 206 journals suggests are either absent (34%), weak, incoherent, or neglected by researchers, could provide a practical, effective, and rapidly imposed …

British Columbia has the greatest biological diversity of any province or territory in Canada. Yet increasing numbers of species in British Columbia are threatened with extinction. The current patchwork of provincial laws and regulations has not effectively prevented species declines. Recently, the Provincial Government has committed to enacting an endangered species law. Drawing upon our scientific and legal expertise, we offer recommendations for key features of endangered species legislation that build upon strengths and avoid weaknesses observed elsewhere. We recommend striking an independent Oversight Committee to provide recommendations about listing species, organize Recovery Teams, and monitor the efficacy of actions …

Chris Darimont, PhD
Guided by deeply held cultural values, First Nations in Canada are rapidly regaining legal authority to manage natural resources. We present a research collaboration among academics, tribal government, provincial and federal government, resource managers, conservation practitioners, and community leaders supporting First Nation resource authority and stewardship. First, we present results from a molecular genetics study of grizzly bears inhabiting an important conservation area within the territory of the Heiltsuk First Nation in coastal British Columbia. Noninvasive hair sampling occurred between 2006 and 2009 in the Koeye watershed, a stronghold for grizzly bears, salmon, and Heiltsuk people. Molecular demographic analyses revealed …
Population Genetic Structure Of Gray Wolves (Canis Lupus) In A Marine Archipelago Suggests Island-Mainland Differentiation Consistent With Dietary Niche, Astrid V. Stronen, Erin L. Navid, Michael S. Quinn, Paul C. Paquet, Heather M. Bryan, Chris T. Darimont
Population Genetic Structure Of Gray Wolves (Canis Lupus) In A Marine Archipelago Suggests Island-Mainland Differentiation Consistent With Dietary Niche, Astrid V. Stronen, Erin L. Navid, Michael S. Quinn, Paul C. Paquet, Heather M. Bryan, Chris T. Darimont
Chris Darimont, PhD
Background: Emerging evidence suggests that ecological heterogeneity across space can influence the genetic structure of populations, including that of long-distance dispersers such as large carnivores. On the central coast of British Columbia, Canada, wolf (Canis lupus L., 1758) dietary niche and parasite prevalence data indicate strong ecological divergence between marine-oriented wolves inhabiting islands and individuals on the coastal mainland that interact primarily with terrestrial prey. Local holders of traditional ecological knowledge, who distinguish between mainland and island wolf forms, also informed our hypothesis that genetic differentiation might occur between wolves from these adjacent environments.
Results: We used microsatellite genetic markers …
Online Hunting Forums Identify Achievement As Prominent Among Multiple Satisfactions, Alena M. Ebeling-Schuld, Chris T. Darimont
Online Hunting Forums Identify Achievement As Prominent Among Multiple Satisfactions, Alena M. Ebeling-Schuld, Chris T. Darimont
Chris Darimont, PhD
Understanding hunter satisfactions can lead to improved wildlife management policy and practice. Whereas previous work has suggested that hunters often seek multiple satisfactions (achievement, affiliation, appreciation), little is known about how satisfactions might vary with target species. Additionally, past research has mostly gathered data using interviews and surveys, which might limit scope as well as introduce strategic bias for potentially provocative subjects such as hunting. To address these gaps, we analyzed data from online hunting forums, which provide an open-access source of peer-to-peer discussion that is geographically and taxonomically broad. We used directed qualitative content analysis to analyze hunting narratives …
What Enables Size-Selective Trophy Hunting Of Wildlife?, Chris T. Darimont, K. Rosie Child
What Enables Size-Selective Trophy Hunting Of Wildlife?, Chris T. Darimont, K. Rosie Child
Chris Darimont, PhD
Although rarely considered predators, wildlife hunters can function as important ecological and evolutionary agents. In part, their influence relates to targeting of large reproductive adults within prey populations. Despite known impacts of sizeselective harvests, however, we know little about what enables hunters to kill these older, rarer, and presumably more wary individuals. In other mammalian predators, predatory performance varies with knowledge and physical condition, which accumulates and declines, respectively, with age. Moreover, some species evolved camouflage as a physical trait to aid in predatory performance. In this work, we tested whether knowledge-based faculty (use of a hunting guide with accumulated …
Intrapopulation Diversity In Isotopic Niche Over Landscapes: Spatial Patterns Inform Conservation Of Bear–Salmon Systems, Megan S. Adams, Christina N. Service, Andrew Bateman, Mathieu Bourbonnais, Kyle A. Artelle, Trisalyn Nelson, Paul C. Paquet, Taal Levi, Chris T. Darimont

Chris Darimont, PhD
Intrapopulation variability in resource acquisition (i.e., niche variation) influences population dynamics, with important implications for conservation planning. Spatial analyses of niche variation within and among populations can provide relevant information about ecological associations and their subsequent management. We used stable isotope analysis and kernel-weighted regression to examine spatial patterns in a keystone consumer–resource interaction: salmon (Oncorhynchus spp.) consumption by grizzly and black bears (Ursus arctos horribilis, n = 886; and Ursus americanus, n = 557) from 1995 to 2014 in British Columbia (BC), Canada. In a region on the central coast of BC (22,000 km2 ), grizzly bears consumed …

Many species at risk in Canada and globally are at or approaching a crisis, especially where little or nothing consequential is being done to prevent extirpation. Such is the case of endangered boreal caribou (Rangifer tarandus caribou) in southern Alberta, Canada. Expedient but inadequate emergency ‘fixes’ have been experimentally implemented to arrest their decline and potential extirpation, but use of these measures raises important ethical problems. In their study of the effects of killing wolves (Canis lupus) on the Little Smoky woodland caribou population, Hervieux et al. (2014a) employed lethal methods that included shooting a firearm from a helicopter and …

Trophy hunting has occupied a prominent position in recent scholarly literature and popular media. In the scientific conservation literature, researchers are generally supportive of or sympathetic to its usage as a source of monetary support for conservation. Although authors at times acknowledge that trophy hunting faces strong opposition from many members of the public, often for unspecified reasons associated with ethics, neither the nature nor the implications of these ethical concerns have been substantively addressed. We identify the central act of wildlife “trophy” taking as a potential source of ethical discomfort and public opposition. We highlight that trophy hunting entails …

Why Men Trophy Hunt, Chris T. Darimont, Brian F. Codding, Kristen Hawkes
Chris Darimont, PhD
The killing of Cecil the lion (Panthera leo) ignited enduring and increasingly global discussion about trophy hunting. Yet, policy debate about its benefits and costs focuses only on the hunted species and biodiversity, not the unique behaviour of hunters. Some contemporary recreational hunters from the developed world behave curiously, commonly targeting ‘trophies’: individuals within populations with large body or ornament size, as well as rare and/or inedible species, like carnivores. Although contemporary hunters have been classified according to implied motivation (i.e. for meat, recreation, trophy or population control, as well the ‘multiple satisfactions’ they seek while hunting (affiliation, …
Mismeasured Mortality: Correcting Estimates Of Wolf Poaching In The United States, Adrian Treves, Kyle A. Artelle, Chris T. Darimont, David R. Parsons
Mismeasured Mortality: Correcting Estimates Of Wolf Poaching In The United States, Adrian Treves, Kyle A. Artelle, Chris T. Darimont, David R. Parsons
Chris Darimont, PhD
Measuring rates and causes of mortalities is important in animal ecology and management. Observing the fates of known individuals is a common method of estimating life history variables, including mortality patterns. It has long been assumed that data lost when known animals disappear were unbiased. We test and reject this assumption under conditions common to most, if not all, studies using marked animals. We illustrate the bias for 4 endangered wolf populations in the United States by reanalyzing data and assumptions about the known and unknown fates of marked wolves to calculate the degree to which risks of different causes …
Indigenous Knowledge And Science Unite To Reveal Spatial And Temporal Dimensions Of Distributional Shift In Wildlife Of Conservation Concern, Christina N. Service, Megan S. Adams, Kyle A. Artelle, Paul C. Paquet, Laura V. Grant, Chris T. Darimont
Indigenous Knowledge And Science Unite To Reveal Spatial And Temporal Dimensions Of Distributional Shift In Wildlife Of Conservation Concern, Christina N. Service, Megan S. Adams, Kyle A. Artelle, Paul C. Paquet, Laura V. Grant, Chris T. Darimont
Chris Darimont, PhD
Range shifts among wildlife can occur rapidly and impose cascading ecological, economic, and cultural consequences. However, occurrence data used to define distributional limits derived from scientific approaches are often outdated for wide ranging and elusive species, especially in remote environments. Accordingly, our aim was to amalgamate indigenous and western scientific evidence of grizzly bear (Ursus arctos horribilis) records and detail a potential range shift on the central coast of British Columbia, Canada. In addition, we test the hypothesis that data from each method yield similar results, as well as illustrate the complementary nature of this coupled approach. Combining information from …
Hunting As A Management Tool? Cougar-Human Conflict Is Positively Related To Trophy Hunting, Kristine J. Teichman, Bogdan Cristescu, Chris T. Darimont
Hunting As A Management Tool? Cougar-Human Conflict Is Positively Related To Trophy Hunting, Kristine J. Teichman, Bogdan Cristescu, Chris T. Darimont
Chris Darimont, PhD
Background: Overexploitation and persecution of large carnivores resulting from conflict with humans comprise major causes of declines worldwide. Although little is known about the interplay between these mortality types, hunting of predators remains a common management strategy aimed at reducing predator-human conflict. Emerging theory and data, however, caution that such policy can alter the age structure of populations, triggering increased conflict in which conflict-prone juveniles are involved.
Results: Using a 30-year dataset on human-caused cougar (Puma concolor) kills in British Columbia (BC), Canada, we examined relationships between hunter-caused and conflict-associated mortality. Individuals that were killed via conflict with humans were …

Ecology Of Conflict: Marine Food Supply Affects Human-Wildlife Interactions On Land, Kyle A. Artelle, Sean Anderson, John D. Reynolds, Andrew B. Cooper, Paul C. Paquet, Chris T. Darimont
Chris Darimont, PhD
Human-wildlife conflicts impose considerable costs to people and wildlife worldwide. Most research focuses on proximate causes, offering limited generalizable understanding of ultimate drivers. We tested three competing hypotheses (problem individuals, regional population saturation, limited food supply) that relate to underlying processes of human-grizzly bear (Ursus arctos horribilis) conflict, using data from British Columbia, Canada, between 1960–2014. We found most support for the limited food supply hypothesis: in bear populations that feed on spawning salmon (Oncorhynchus spp.), the annual number of bears/km2killed due to conflicts with humans increased by an average of 20% (6–32% [95% CI]) for each 50% …
