    Conservation biologists need to effectively monitor species given resource limitations and the inherent challenges of assessing long‐term demographic processes. We assessed gopher tortoise (Gopherus polyphemus) abundance at a landscape scale and at the scale of 3 local populations within the Conecuh National Forest (CNF), Alabama, USA, between 1991 and 2017. We collected landscape‐level data from line

    Density dependence, immigration, and emigration can considerably influence wildlife population demographics. Population models used to evaluate common actions like predator management and harvest in the absence of these processes may lead to poor management decisions. We built a novel population simulation model for the northern bobwhite (Colinus virginianus; bobwhite) that included implicit spatial

    The primary data underlying worldwide conservation efforts come from observational field studies (Butchart et al. 2010, Geijzendorffer et al. 2016, Proença et al. 2017). Large‐scale networks for biodiversity monitoring, especially based on citizen science, have been important sources of standardized time‐series datasets that feed biodiversity indicators (Bunce et al. 2008, Proença et al. 2017, Guralnick

  • Ecological Discord and the Importance of Scale in Scientific Inquiry
    J. Wildl. Manage. (IF 2.215) Pub Date : 2020-08-15
    Fidel Hernández

    Scale is widely recognized today as an important concept in ecology because the scale of investigation determines the patterns and processes that can be observed. Ecological investigations can produce different outcomes depending on the scale at which observations are made, and ecological disagreements have occurred simply because investigators addressed the same question using different scales. Here

    Changing predator communities have been implicated in reduced survival of white‐tailed deer (Odocoileus virginianus) fawns. Few studies, however, have used field‐based age‐specific estimates for survival and fecundity to assess the relative importance of low fawn survival on population growth and harvest potential. We studied white‐tailed deer population dynamics on Tensas River National Wildlife Refuge

  • Variation in Survival and Harvest Rates in Florida Mottled Duck
    J. Wildl. Manage. (IF 2.215) Pub Date : 2020-09-04

    North American waterfowl harvest regulations are largely guided by the status of breeding populations. Nonetheless, understanding the demographics of wintering waterfowl populations can elucidate the effects of hunting pressure on population dynamics. The ring‐necked duck (Aythya collaris) breeds and winters in all North American administrative flyways and is one of the most abundant and most harvested

    J. Wildl. Manage. (IF 2.215) Pub Date : 2020-08-25
    Katie A. Harris; Joseph D. Clark; R. Dwayne Elmore; Craig A. Harper

    Eastern box turtles (Terrapene carolina carolina) are widely distributed throughout the eastern United States. Although once common throughout much of its distribution, the species has experienced declines in local populations. Understanding resource selection is important for the conservation of this species; however, few data exist on resource selection for eastern box turtles in the southeastern

  • Contrasting Effects of Climate Change on Alpine Chamois
    J. Wildl. Manage. (IF 2.215) Pub Date : 2020-10-19
    Roberta Chirichella; Philip A. Stephens; Tom H. E. Mason; Marco Apollonio

    Global climate change can affect animal ecology in numerous ways, but researchers usually emphasize undesirable consequences. Temperature increases, for instance, can induce direct physiological costs and indirect effects via mismatches in resource needs and availability. Species living in mountainous regions, however, could experience beneficial effects because winters might become less severe. We

  • Female Moose Prioritize Forage Over Mortality Risk in Harvested Landscapes
    J. Wildl. Manage. (IF 2.215) Pub Date : 2020-10-19
    Alexandra L. Francis; Chris Procter; Gerald Kuzyk; Jason T. Fisher

    Since 2010, several moose (Alces alces) populations have declined across North America. These declines are believed to be broadly related to climate and landscape change. At the western reaches of moose continental range, in the interior of British Columbia, Canada, wildlife managers have reported widespread declines of moose populations. Disturbances to forests from a mountain pine beetle (Dendroctonum

    J. Wildl. Manage. (IF 2.215) Pub Date : 2020-10-19
    Alberto L. Scorolli

    Feral invasive mammals challenge management strategies worldwide including the feral horse (Equus caballus) population in Tornquist Park, Argentina. In this study, I constructed population matrix models using demography data collected between 1995 and 2002. I validated the models with independent counts from 2008 to 2016. I individually identified feral horses and recorded them as I walked a fixed

    J. Wildl. Manage. (IF 2.215) Pub Date : 2020-10-01
    Tom S. Smith; James M. Wilder; Geoffrey York; Martyn E. Obbard; Blake W. Billings

    Several studies have documented the effectiveness of bear spray in protecting users from aggressive bears. Bear spray failures, however, have also been reported along with speculation regarding the influences of temperature, wind, repeated canister use, and canister age on spray efficacy. We designed lab and field experiments to document the influence that temperature, wind, repeated discharges from

    The influence of weather on wildlife populations has been documented for many species; however, much of the current literature has focused on the effects of weather within a season and consists of short‐term studies. The use of long‐term datasets that cover a variety of environmental conditions will be essential for assessing possible carry‐over effects of weather experienced in one season on behavior

  • Factors Influencing Survival Rates of Pronghorn Fawns in Idaho
    J. Wildl. Manage. (IF 2.215) Pub Date : 2020-09-17
    Brett R. Panting; Eric M. Gese; Mary M. Conner; Scott Bergen

    Pronghorn (Antilocapra americana) occur throughout western North America. In Idaho, USA, following intensive hunting to reduce crop depredations in the late 1980s, pronghorn populations have not rebounded to desired levels. Because neonatal survival in ungulates is one factor limiting population growth, we evaluated cause‐specific mortality and the influence of intrinsic and extrinsic factors on survival

  • Estimating Abundance of an Unmarked, Low‐Density Species using Cameras
    J. Wildl. Manage. (IF 2.215) Pub Date : 2020-09-03
    Kenneth E. Loonam; David E. Ausband; Paul M. Lukacs; Michael S. Mitchell; Hugh S. Robinson

    Estimating abundance of wildlife populations can be challenging and costly, especially for species that are difficult to detect and that live at low densities, such as cougars (Puma concolor). Remote, motion‐sensitive cameras are a relatively efficient monitoring tool, but most abundance estimation techniques using remote cameras rely on some or all of the population being uniquely identifiable. Recently

  • Important Considerations when Using Models
    J. Wildl. Manage. (IF 2.215) Pub Date : 2020-07-22
    Paul R. Krausman

    A Ph.D. student entered my office at the University of Arizona and asked me to review a habitat model for a desert ungulate that was part of their dissertation. I gladly did so, and when the student returned for my comments, I gave my opinion and asked how they thought the habitat characteristics afield aligned with those in the model. The study area was only a few hours southwest of the university

  • Seasonal Use of Latrines by Bobcats: Implications for Monitoring Programs

    For species at risk, it is important that demographic models be consistent with our most recent knowledge because alternate model versions can have differing predictions for wildlife and natural resource management. To establish and maintain this consistency, we can compare predicted model values to current or past observations and demographic knowledge. When novel predictor information becomes available

  • Comparing Survival and Movements of Non‐Urban and Urban Translocated Mule Deer
    J. Wildl. Manage. (IF 2.215) Pub Date : 2020-08-06
    Chloe A. Wright; Ian T. Adams; Patrick Stent; Adam T. Ford

    In many parts of North America, deer (Odocoileus spp.) have adapted to live in urban areas and are a source of negative human‐wildlife interactions. Management strategies such as culling, immunocontraceptives, sterilization, and translocation have been implemented to manage urban deer populations. In the East Kootenay region of southern British Columbia, urban mule deer (Odocoileus hemionus) populations

    Amanda R. Goldberg; Courtney J. Conway; Diane Evans Mack; Greg Burak

    Hibernation is a strategy many species employ to survive periods of thermal stress or resource shortage (e.g., harsh thermal conditions, food limitations) and habitat requirements of hibernating species may differ between summer (the active season) and winter (during hibernation). Accounting for seasonal differences in habitat affinities will help ensure that management actions are more beneficial

  • Interchange and Overlap Among Four Adjacent Arctic Caribou Herds

    Population manipulations such as translocation and head‐starting are increasingly used as recovery tools for chelonians. But evaluating success of individual projects can require decades of monitoring to detect population trends in these long‐lived species. Furthermore, there are often few benchmarks from stable, unmanipulated populations against which to compare demographic rates, particularly for

    Trapping data have a long and rich history of use in monitoring furbearer populations in North America but understanding the influences of variation in trapper harvest is important. Many factors besides abundance can cause variation in trapper harvest, including socioeconomics, weather, and motivation. The relationships between these extrinsic factors and trapper harvest may change temporally, which

    Information garnered from the capture and handling of free‐ranging animals helps advance understanding of wildlife ecology and can aid in decisions on wildlife management. Unfortunately, animals may experience increased levels of stress, injuries, and death resulting from captures (e.g., exertional myopathy, trauma). Partial sedation is a technique proposed to alleviate stress in animals during capture

  • Use of Upland and Riparian Areas by Wintering Bald Eagles and Implications for Wind Energy

    The pygmy rabbit (Brachylagus idahoensis) is endemic to the sagebrush steppe landscapes in the western United States. Pygmy rabbits have adapted to this region by depending on big sagebrush (Artemisia tridentata) as a source of nutrition and concealment from predators. Being a central place forager, and a dietary specialist makes pygmy rabbits an ideal subject to study foraging tradeoffs. Our objectives

    Livestock grazing is a predominant land use worldwide and can influence wildlife populations by altering grassland composition, structure, and productivity. Conceptually, rest‐rotation livestock grazing could increase pasture‐level heterogeneity that would allow wildlife to balance the need for resources with the risk of predation. Prairie‐grouse (Tympanuchus spp.) are recognized as important indicator

    Lead remnants from spent ammunition introduce health risks to humans and wildlife that consume game harvested with firearms. Most current research has focused on effects of high‐velocity rifle bullets, whereas low‐velocity lead ammunition has received little attention. We examined whether fragmentation characteristics differed between 3 common low‐velocity ammunition types when shot into the thoracic

  • Anthropogenic and Natural Disturbance Differentially Affect Sagebrush Bird Habitat Use

    North American sagebrush (Artemisia spp.)‐obligate birds are experiencing steep population declines due in part to increased disturbance, mainly human‐caused, across their range. At the eastern edge of the sagebrush steppe, this issue may potentially be exacerbated because of natural disturbance by black‐tailed prairie dogs (Cynomys ludovicianus). Our goal was to compare local and landscape models

  • Extensive Use of Intertidal Habitat by Shorebirds Outside Protected Nesting Areas

    Conservation of shorebirds throughout their breeding and migratory ranges has become a priority as shorebird populations decline globally. Along the North Atlantic Coast, management efforts have particularly focused on preserving nesting habitat for piping plovers (Charadrius melodus), which are protected under the Endangered Species Act. It is unclear whether these conservation measures suffice to

  • Using Biophysical Models to Improve Survey Efficiency for Cryptic Ectotherms

    Inefficiencies in monitoring programs waste resources. Ideally, we would predict when and where target species are most detectable and place our effort accordingly. Statistical models can generate predictor functions relating survey conditions to detectability but are phenomenological; they do not incorporate biological constraints and so using them to predict into unsampled time and space is risky

  • Behavior and Movement of Wild Turkey Broods
    J. Wildl. Manage. (IF 2.215) Pub Date : 2020-06-03

    Behavioral and movement ecology of broods are among the most poorly understood aspects of wild turkey (Meleagris gallopavo) reproductive ecology. Recent declines in wild turkey productivity throughout the southeastern United States necessitate comprehensive evaluations of brood ecology across multiple spatial scales. We captured and marked 408 female wild turkeys with global positioning system (GPS)‐transmitters

    Wilson, R. R., and G. M. Durner. 2020. Seismic survey design and effects on maternal polar bear dens. Journal of Wildlife Management 84:201–212. Since the publication of this manuscript, readers have noted 2 errors in our analysis. Here, we describe the errors and the changes to the supplemental code that will remedy them. The changes do not affect either the resulting expected number of maternal polar

  • Ranging Behavior of an Arboreal Marsupial in a Plantation Landscape

    Forests are becoming increasingly fragmented, primarily because of their conversion to production landscapes. Animals occupying modified landscapes may need to expand their ranges and move longer distances between remnant forest patches to find resources. The establishment of plantations in fragmented landscapes, however, may provide complementary habitat for wildlife and improve connectivity, reducing

  • Annual Pronghorn Survival of a Partially Migratory Population
    J. Wildl. Manage. (IF 2.215) Pub Date : 2020-05-30

    The importance of conserving migratory populations is recognized across a variety of ungulate taxa, yet the demographic benefits of migration remain uncertain for ungulate populations that exhibit partial migration. We hypothesized that migratory pronghorn (Antilocapra americana) would experience greater survival compared to residents by moving longer distances to avoid severe winter weather and access

  • Bighorn Sheep Genetic Structure in Wyoming Reflects Geography and Management

    Aligning wildlife management boundaries with accurate biological units promotes effective conservation and management practices that reflect ecological and evolutionary processes. Neutral genetic markers allow for quantitative delineation of population structure without a priori assumptions or biases. In the United States, bighorn sheep (Ovis canadensis) are a charismatic component of Wyoming's biodiversity

  • Assessing Population Viability of Black Bears using Spatial Capture‐Recapture Models

    The Central Georgia Bear Population (CGP) is the least abundant and most isolated of Georgia's 3 American black bear (Ursus americanus) populations. Beginning in 2011, changes to regulations governing harvest of the CGP resulted in an increase in female bear harvest, creating concern that future harvest could be an important influence on population viability. Hence, our objective was to assess viability

  • Precipitation and Reproduction are Negatively Associated with Female Turkey Survival

    Understanding how reproductive tradeoffs act in concert with abiotic elements to affect survival is important for effective management and conservation of wildlife populations, particularly for at‐risk or harvested species. Wild turkeys (Meleagris gallopavo) are a high‐interest species for consumptive and non‐consumptive uses, and female survival is a primary factor influencing turkey population dynamics
