    Michael J. Chamberlain; Bradley S. Cohen; Nicholas W. Bakner; Bret A. Collier

    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

    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 1.881) Pub Date : 2020-05-30
    Paul F. Jones; Andrew F. Jakes; Daniel R. Eacker; Mark Hebblewhite

    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

    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

    Wildlife professionals are tasked with sustainably managing habitats and wildlife for the benefit of a variety of stakeholders, and hunters are an important user group. But the number of hunters in North America has continued to decline, and as a result, new wildlife professionals entering the field are less likely to be hunters than their predecessors. We find this trend concerning because future

  • Avian Predation on Steelhead is Consistent with Compensatory Mortality
    J. Wildl. Manage. (IF 1.881) Pub Date : 2020-05-15
    Steven L. Haeseker; Gabriel Scheer; Jerry McCann

    Numerous factors such as predation, disease, injury, and environmental conditions (e.g., river flows, hydropower operations) can influence survival rates of fish. Although mortality due to predation is commonly assumed to be additive and result in a directly proportional reduction on survival rates, compensatory processes may work to counteract or negate the effects of predation mortality on survival

  • Writing an Effective Title
    J. Wildl. Manage. (IF 1.881) Pub Date : 2020-05-13
    Paul R. Krausman; Allison S. Cox

    Every aspect of scientific writing has been examined, but the title is the least studied component of manuscripts (Goodman et al. 2001, Soler 2007) even though some describe the title as the most important element (Garg 2017). When scientists are scanning literature to decide what to read, the title is often the only thing they look at (Stapleton et al. 1995). Useful guidelines for titles are often

    Understanding how species respond to environmental conditions can assist with conservation strategies and harvest management, especially in arctic and boreal regions that are experiencing rapid climate change. Although climatic influences on species distributions have been studied, broad‐scale effects of climate on survival are less well known. We examined the interactive effects of meteorological

  • The Necessity of Manuscript Rejection
    J. Wildl. Manage. (IF 1.881) Pub Date : 2020-04-20
    Paul R. Krausman

    Every year, I am asked why manuscripts are rejected from the Journal of Wildlife Management (JWM ), often by wildlife students and early career professionals. And, whenever I see the statistics on rejection rates for JWM (>50%), my first reaction is to cringe. Rejecting more than half of the submitted manuscripts seems draconian; but then again, rejection rates for most major journals are high. And

  • Disturbance Caused by Aerial Waterfowl Surveys During the Nonbreeding Season

    Andrew D. Gilbert; Christopher N. Jacques; Joseph D. Lancaster; Aaron P. Yetter; Heath M. Hagy

    Aerial surveys flown at low altitudes allow detection, identification, and enumeration of waterfowl and other waterbirds, but few studies have assessed disturbance to these guilds during the nonbreeding period. Excessive disturbance can potentially increase energy expenditure and exposure to hunting mortality contrary to objectives of many waterfowl sanctuaries where surveys are conducted. We used

  • Land Cover Switching in Autumn by Female Mallards in Ohio
    J. Wildl. Manage. (IF 1.881) Pub Date : 2020-04-14
    Brendan T. Shirkey; Matthew D. Palumbo; John W. Simpson

    Autumn waterfowl habitat management often focuses on providing high energy food resources to attract and concentrate waterfowl for harvest. Similarly, many waterfowl conservation plans assume food resources are the primary, controllable limiting factor influencing waterfowl distribution during migration; however, hunting‐related disturbance also influences waterfowl distribution in autumn. We investigated

    An estimate or index of target species density is important in determining oral rabies vaccination (ORV) bait densities to control and eliminate specific rabies variants. From 1997–2011, we indexed raccoon (Procyon lotor ) densities 253 times based on cumulative captures on 163 sites from Maine to Alabama, USA, near ORV zones created to prevent raccoon rabies from spreading to new areas. We conducted

    Daniel P. Thompson; John A. Crouse; Thomas J. McDonough; Perry S. Barboza; Scott Jaques

    Management and research of moose (Alces alces) in Alaska, USA, often require chemical immobilization; however, moose may be prone to capture‐induced hyperthermia while immobilized. We chemically immobilized moose with carfentanil citrate and xylazine hydrochloride to measure rump fat depth, collect blood and fecal samples, and to deploy modified vaginal implant transmitters and global positioning system

  • Investigating Support for Management of the Pet Trade Invasion Risk
    J. Wildl. Manage. (IF 1.881) Pub Date : 2020-04-09
    Diane J. Episcopio‐Sturgeon; Elizabeth F. Pienaar

    The non‐native pet trade contributes directly to species invasions, thereby threatening wildlife. Biological invasions influence environmental change, resulting in species extinctions and biodiversity loss. To mitigate the pet trade invasion risk, interventions are required to prevent trade in non‐native animals with high invasion potential, impulse or ill‐informed purchases of non‐native pets by individuals

  • Black Bear Movement and Food Conditioning in an Exurban Landscape
    J. Wildl. Manage. (IF 1.881) Pub Date : 2020-04-09
    Jessica L. Braunstein; Joseph D. Clark; Ryan H. Williamson; William H. Stiver

    Conflicts between humans and wildlife have become increasingly important challenges for resource managers along the urban‐wildland interface. Food conditioning (i.e., reliance by an animal on anthropogenic foods) of American black bears (Ursus americanus) is related to conflict behavior (i.e., being bold or aggressive toward humans, consuming human food or garbage, causing property damage) and often

  • Population and Harvest Dynamics of Midcontinent Sandhill Cranes
    J. Wildl. Manage. (IF 1.881) Pub Date : 2020-03-31
    Aaron T. Pearse; Glen A. Sargeant; Gary L. Krapu; David A. Brandt

    Sandhill cranes (Antigone canadensis ) inhabiting the midcontinent of North America have been hunted since the 1960s under management goals of maintaining abundance, retaining geographic distribution, and maximizing sustainable harvest. Some biologists have raised concerns regarding harvest sustainability because sandhill cranes have lower reproductive rates than other game birds. We summarized demographic

    Mark P. Herzog; Joshua T. Ackerman; C. Alex Hartman; Sarah H. Peterson

    Radio‐telemetry is a commonly used scientific technique that allows researchers to collect detailed movement, habitat use, and survival data of animals; however, evidence indicates that using telemetry can affect behavior and survival. Using multiple breeding colonies and years, we investigated the effects of attached radio‐transmitters on growth and survival of Forster's tern (Sterna forsteri ) chicks

  • Dogs Detect Larger Wind Energy Effects on Bats and Birds
    J. Wildl. Manage. (IF 1.881) Pub Date : 2020-03-26
    K. Shawn Smallwood; Douglas A. Bell; Skye Standish

    As wind turbine‐caused mortality of birds and bats increases with increasing wind energy capacity, accurate fatality estimates are needed to assess effects, identify collision factors, and formulate mitigation. Finding a larger proportion of collision victims reduces the magnitude of adjustment for the proportion not found, thus reducing opportunities for bias. We tested detection dogs in trials of

  • Synergistic Population Density and Environmental Effects on Deer Body Condition
    J. Wildl. Manage. (IF 1.881) Pub Date : 2020-03-25
    Pascale Ayotte; Mael Le Corre; Steeve D. Côté

    The ability to predict energy and protein allocation to different body condition parameters according to environmental constraints is a key component in understanding the processes underlying population dynamics. We investigated the influence of a proxy of population density and environmental factors on individual body condition parameters of female white‐tailed deer (Odocoileus virginianus ) based

    Scientific progress depends upon the accumulation of empirical knowledge via reproducible methodology. Although reproducibility is a main tenet of the scientific method, recent studies have highlighted widespread failures in adherence to this ideal. The goal of this study was to gauge the level of computational reproducibility, or the ability to obtain the same results using the same data and analytic

  • Overabundance of Black‐Tailed Deer in Urbanized Coastal California
    J. Wildl. Manage. (IF 1.881) Pub Date : 2020-03-16
    Brett J. Furnas; Russ H. Landers; Rhonda G. Paiste; Benjamin N. Sacks

    Abundance of mule deer (Odocoileus hemionus ) in western North America is often considered lower than desirable for hunting. Some coastal populations of Columbian black‐tailed deer (O. h. columbianus ) in California, USA, near urban development, however, are perceived as a nuisance and may be overabundant. To determine the density of a potential nuisance population in Marin County, California, we used

    In the western United States, wolverines (Gulo gulo ) typically occupy high‐elevation habitats. Because wolverine populations occur in vast, remote areas across multiple states, biologists have an imperfect understanding of this species' current distribution and population status. The historical extirpation of the wolverine, a subsequent period of recovery, and the lack of a coordinated monitoring

  • Midyear Status of The Journal of Wildlife Management, 2020

    Fine‐scale movement data has transformed our knowledge of ungulate migration ecology and now provides accurate, spatially explicit maps of migratory routes that can inform planning and management at local, state, and federal levels. Among the most challenging land use planning issues has been developing energy resources on public lands that overlap with important ungulate habitat, including the migratory

  • Effects of Wind Turbine Curtailment on Bird and Bat Fatalities
    J. Wildl. Manage. (IF 1.881) Pub Date : 2020-02-27
    K. Shawn Smallwood; Douglas A. Bell

    Bird and bat fatalities increase with wind energy expansion and the only effective fatality‐reduction measure has been operational curtailment, which has been documented for bats but not for birds. We performed opportune before‐after, control‐impact (BACI) experiments of curtailment effects on bird and bat fatalities and nocturnal passage rates during fall migration at 2 wind projects, where 1 continued

  • Multi‐Scale Assessment of Male Northern Yellow Bat Roost Selection

    Size‐selective harvesting of wild ungulates can trigger a range of ecological and evolutionary consequences. It remains unclear how environmental conditions, including changes in habitat, climate, and local weather conditions, dilute or strengthen the effects of trophy hunting. We analyzed horn length measurements of 2,815 male ibex (Capra pyrenaica) that were harvested from 1995 to 2017 in Els Ports

    Supplementary feeding is often used as a conservation tool to reverse the decline of food‐limited populations. The arctic fox (Vulpes lagopus) is one of the most endangered mammals in Norway and has been the target of several conservation initiatives for almost 3 decades, including supplementary feeding. To measure and improve the efficiency of supplementary feeding as a conservation action, we used

    As the interest for nature‐based tourism activities increases, it is important to provide evidence‐based guidelines for wildlife‐human interactions to minimize the disturbance caused to wildlife. In Fennoscandia, the endangered arctic fox (Vulpes lagopus) is subject to increasing tourism interest and some regions recommend a minimum approach distance of 300 m, but the guidelines have not been scientifically

    Resident populations of Canada geese (Branta canadensis) are of particular management interest throughout the eastern United States given increased human‐wildlife conflicts due to regional increases in the Atlantic Flyway Resident Population. Within Virginia, USA, growth rates of resident goose populations have been reduced through extended harvest seasons and increased bag limits. Our objective was

  • Similar Bird Communities Across Grazing Systems in the Nebraska Sandhills

    Much of the remaining native rangeland in the Great Plains in the United States is privately owned and managed for beef production, and this single priority for land use may be contributing to declining avian biodiversity through a loss of structural heterogeneity. One proposed solution is to use multiple grazing systems across ranches, under the assumption that this approach will increase heterogeneity

  • Indirect effects of red imported fire ants on Attwater's prairie-chicken brood survival.

    The invasive red imported fire ant (Solenopsis invicta) has negatively affected a host of taxonomic groups throughout its acquired North American range. Many studies have hypothesized indirect trophic impacts, but few documented those impacts. We evaluated invertebrate abundance as a factor limiting juvenile survival of the endangered Attwater's prairie-chicken (Tympanuchus cupido attwateri), and whether

  • Elk Resource Selection and Implications for Anthrax Management in Montana.

    Anthrax, caused by the spore-forming bacterium Bacillus anthracis, is a zoonotic disease that affects humans and animals throughout the world. In North America, anthrax outbreaks occur in livestock and wildlife species. Vaccine administration in wildlife is untenable; the most effective form of management is surveillance and decontamination of carcasses. Successful management is critical because untreated

  • Applying a random encounter model to estimate lion density from camera traps in Serengeti National Park, Tanzania.

    The random encounter model (REM) is a novel method for estimating animal density from camera trap data without the need for individual recognition. It has never been used to estimate the density of large carnivore species, despite these being the focus of most camera trap studies worldwide. In this context, we applied the REM to estimate the density of female lions (Panthera leo) from camera traps

  • Insufficient Sampling to Identify Species Affected by Turbine Collisions.

    We compared the number of avian species detected and the sampling effort during fatality monitoring at 50 North American wind facilities. Facilities with short intervals between sampling events and high effort detected more species, but many facilities appeared undersampled. Species accumulation curves for 2 wind facilities studied for more than 1 year had yet to reach an asymptote. The monitoring

  • Den Entry Behavior in Scandinavian Brown Bears: Implications for Preventing Human Injuries.

    Encounters between Scandinavian brown bears (Ursus arctos) and humans that result in human injuries and fatalities typically coincide with den entry in October and November, and commonly occur near a den. Our aim was to determine when bears arrive at their dens, identify potential predictors of this event, document behavior and activity associated with this period, and attempt to explain the increased

  • Barred owls and landscape attributes influence territory occupancy of northern spotted owls.

    We used multi-season occupancy analyses to model 2 fates of northern spotted owl territories in relation to habitat amount, habitat fragmentation, and the presence of barred owls in Washington State, USA, 1989-2005. Local colonization is the probability a territory unoccupied by a spotted owl in year i would be occupied in year i + 1, and local extinction is the probability a territory that was occupied

  • Does despotic behavior or food search explain the occurrence of problem brown bears in Europe?

    Bears foraging near human developments are often presumed to be responding to food shortage, but this explanation ignores social factors, in particular despotism in bears. We analyzed the age distribution and body condition index (BCI) of shot brown bears in relation to densities of bears and people, and whether the shot bears were killed by managers (i.e., problem bears; n = 149), in self-defense
