Identifying vulnerable species and understanding any behavioral predictors of mortality helps us understand vulnerability to traffic and can inform management strategies. If anurans use roads to facilitate movement, thermoregulate, or feed, then standard mitigation methods may not be effective. We investigated a 9-species anuran community in tropical Australia with respect to behavioral responses on roads including proportion of time spent on roads, distances and direction moved along roads, and whether feeding was occurring on roads. We also noted if focal individuals were killed during observations, with the aim of assessing any link between mortality and on-road behavior or anuran size. We found no differences among species regarding behavior on roads, no evidence to suggest they use the road as a movement corridor, and no difference in road mortality among species. Our results indicate this anuran community is equally vulnerable to mortality via road traffic, indicating that actions to reduce mortality such as underpasses, signage, and speed restrictions in hotspots will benefit the entire community and thus have high cost-effectiveness.</p>","PeriodicalId":17504,"journal":{"name":"Journal of Wildlife Management","volume":"90 5","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/jwmg.70218","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148238125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Female wild turkey survival may vary spatially and temporally, for example, in relation to land cover and the individual's behavior state, so investigation of the factors that affect female survival is critical to direct long-term management. We radio-tracked 370 female turkeys from 2020 to 2022 to determine spatial and temporal factors that influenced survival across study areas in each of the 3 major ecoregions in North Carolina, USA. We constructed a Bayesian hierarchical model, parameterized using covariates likely to influence survival—year, age class, mean daily distance traveled, land cover type and edge density in the individual's home range, and ecoregion (Coastal Plain, Piedmont, or Mountain)—for 4 behavior states (non-breeding, pre-nesting, incubation, and brood rearing). We recorded 59 (48% of monitored individuals) mortalities in the Mountain ecoregion, 64 (56%) mortalities in the Piedmont ecoregion, and 41 (31%) mortalities in the Coastal Plain ecoregion. Female survival in the pre-nesting and non-breeding states increased with greater average daily distance traveled. No land cover covariate influenced survival estimates within any behavior state. Overall, daily survival rates were lowest for the incubation state (0.993 [SD = 0.003]) and highest during the pre-nesting and brood-rearing states (0.999 [SD = 0.002] and 0.999 [SD = 0.001], respectively). Because mortality risk was greatest during the incubation state, managers may indirectly increase female survival by increasing the amount of nesting cover on the landscape.</p>","PeriodicalId":17504,"journal":{"name":"Journal of Wildlife Management","volume":"90 5","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/jwmg.70213","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148238134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Carcass detection probabilities, however, are often low and data sparse, leading to large uncertainties in fatality estimates. Precision can be improved by pooling information across multiple sites and years. Using post-construction monitoring data from 20 wind farms in Iowa, USA, we evaluated complete pooling (CP), no pooling (NP), and partial pooling (PP) approaches for estimating searcher efficiency, carcass persistence probability, and the fatality estimates obtained by integrating these detection-probability components. For searcher efficiency and persistence probability, PP produced estimates that balanced the extremes of CP and NP, yielding narrower credible intervals than NP, especially at data-limited sites, while preserving meaningful site-level differences. Fatality estimates for 3 bat species, differing in carcass abundance, were generally similar in the PP and NP models, but both were often different from CP. Partial pooling showed gains in precision, especially for abundant species and years with less monitoring effort. A simulation study of scenarios with different amounts of heterogeneity among sites showed that PP provided more accurate predictions than CP and NP in intermediate and high heterogeneity settings. Our findings highlight the value of PP as a flexible strategy for improving detection probability estimation under ecological uncertainty and support its broader application in wildlife impact assessment.</p>","PeriodicalId":17504,"journal":{"name":"Journal of Wildlife Management","volume":"90 5","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/jwmg.70206","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148238157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We used long-term global positioning system (GPS) collar data from 22 adult female plains bison (<i>Bison bison bison</i>) in a fenced enclosure in Grasslands National Park, Canada, to test for density-dependent habitat selection across biologically relevant seasons at 2 spatial scales. The study leveraged a unique opportunity created by a period of natural population growth followed by biennial population reductions to explore how bison adjust habitat use under varying density conditions. Resource selection functions and latent selection difference models showed that bison selected high normalized difference vegetation index (NDVI) areas and avoided roads at low density. As density increased, selection patterns generalized or reversed, especially during the calving and post-calving seasons when nutritional demands were greatest. Bison consistently avoided roads, suggesting they perceive human activity as a form of risk. However, this avoidance declined during the rut, likely because of changes in herd composition and behavioral priorities. Seasonal variation in the strength and direction of selection highlights the complexity of density-dependent space use. Our results emphasize that ignoring density in spatial models may lead to biased management decisions. Understanding how space use shifts with population density is especially important for fully fenced populations that cannot disperse naturally and where intraspecific competition is likely to be exacerbated. In such systems, incorporating density-dependent behavior into species or habitat monitoring is essential for anticipating ecological outcomes and guiding long-term management.</p>","PeriodicalId":17504,"journal":{"name":"Journal of Wildlife Management","volume":"90 5","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/jwmg.70215","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148237573","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although previous work has evaluated the effects of various treatments on forage availability, no study has quantified existing forage availability across a wide geographic area or compared the contribution of all available vegetation types to nutrient availability and quality for deer on a property. We sampled selected white-tailed deer (<i>Odocoileus virginianus</i>) forages on 43 properties managed for deer across 25 states in the eastern United States to evaluate the limitations of biomass and nutritional carrying capacity using 14% crude protein and 0.3% phosphorus constraints across all major vegetation types on each property. We also calculated a relative forage contribution (RFC) value for each vegetation type to determine which contributed more to the total property-level nutrient availability relative to their coverage. Forage availability was limited on most properties. Row crops, food plots, and early successional vegetation provided the greatest forage availability, whereas closed-canopy hardwood forest and pasture/hay provided the least. Early successional vegetation, food plot, and open-canopy hardwood provided the greatest RFC and closed-canopy hardwood forest provided the least. Closed-canopy forest averaged 62.4% coverage, and open-canopy forest and early successional vegetation averaged only 25.2% and 17% coverage, respectively, across all properties where they were present. Extensive coverage of closed-canopy forest with limited forage availability was the primary limitation for deer nutrients on most sites. However, forage estimates in open vegetation types were lower than those reported in the literature, indicating relatively poor management of these vegetation types on most properties. Scenarios where forage production in those vegetation types was increased to correspond with values in the literature led to large increases in property-wide nutrient availability. Even on properties where deer management is a primary objective, our results indicate that most provide relatively poor nutrient availability compared to what is possible with more intensive management. Managers interested in increasing deer forage availability and resulting deer body condition and morphometrics should evaluate available nutrients in the major vegetation types on their property and not only consider more intensive management but also implement management at a greater scale by converting more forest into open woodland and early successional vegetation. Our results can be used by biologists and managers to better understand the potential to influence nutrient availability through more intensive and widespread management.</p>","PeriodicalId":17504,"journal":{"name":"Journal of Wildlife Management","volume":"90 5","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148237813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
