Manatees encounter navigational locks and water control structures along travel corridors, and fatal encounters can occur from crushing, impingement, or entrapment that subsequently result in drowning. Extensive mitigation efforts have been made to protect manatees. This study evaluates the effectiveness of manatee protection systems at navigational locks and water control structures using negative binomial regression models and Friedman's tests with pairwise comparisons from 1974–2020 mortality data. Mitigation effort was stratified into 4 groups ranging from no mitigation to fully mitigated. Regression models for 223 structure-related manatee deaths showed the expected number of annual mortalities was ≤0.26 for all mitigation groups at each structure type. Friedman's tests indicated a difference in mortalities among mitigation efforts for navigational locks (χ₂² = 10.75, <i>P</i> = 0.004) and water control structures (χ₂² = 16.63, <i>P</i> ≤ 0.001). Mortalities at fully mitigated water control structures were lower than at partially mitigated structures in pairwise testing for both analyses; navigational lock mitigation efforts only differed in Wilcoxon rank sums tests. Combined results show that when current manatee protection systems are functional and protocols are followed, mortality is reduced. While these systems are a conservation achievement, continued re-evaluation of mitigation efforts and investigation into new technologies are needed to ensure the continued reduction or elimination of structure-related manatee mortalities.</p>","PeriodicalId":17504,"journal":{"name":"Journal of Wildlife Management","volume":"89 4","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793282","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}

These regulations target the potential for increased animal-animal contact and environmental contamination with CWD prions. Prions, the causative agent of CWD, have been detected on feeder surfaces in CWD-positive, captive deer facilities but not among free-ranging populations, and information on the relative risk of transmission at anthropogenic and natural food sources is limited. In this study, we established and maintained 13 gravity feeders from September 2022 to March 2023 in a CWD zone in northern Mississippi, USA (apparent prevalence ~30%). We set up feeders up in 3 ways: no exclusion (deer feeders, <i>n</i> = 7), exclusion of deer using fencing with holes cut at the ground-level to permit smaller wildlife to enter (raccoon feeders, <i>n</i> = 3), and environmental control feeders, which were fully fenced and not filled with feed (control feeders, <i>n</i> = 3). We swabbed feeder spouts at setup and at 4 intervals approximately 6 weeks apart to test for prion contamination via real-time quaking-induced conversion (RT-QuIC). We detected prions 12 weeks after setup on all deer and raccoon feeders. We compared relative transmission risk using camera traps at these feeders, 6 agronomic plantings for wildlife forage (i.e., food plots), and 7 oak mast trees. Weekly visitation rate by white-tailed deer (<i>Odocoileus virginianus</i>; hereafter: deer) differed (<i>P</i> = 0.02) among deer feeders (median = 24.5 deer/week, range = 15.6–65.7), food plots (median = 12.7, range = 3.8–24.7), and mast trees (median = 2.0, range = 0.4–5.1).

However, variations in parasite surveillance methods and potential biases towards sampling specific host species for this generalist parasite can impede attempts to standardize observed disease patterns across vast regions and into the future. We collected and classified records of winter tick surveillance on ungulate hosts throughout North America to identify trends and biases in species, space, and time, with the aim of identifying gaps and suggesting improvements to existing practices. We conducted a literature review spanning a century of winter tick reports on free-roaming or wild ungulate hosts in North America, resulting in 125 relevant records. From this sample, we compiled information on host species and surveillance method details and categorized winter tick quantification techniques based on their perceived insight for analyses and interventions, assigned as an ecological information value (Eco-IV) ranging from 0 to 3. We examined variations in Eco-IV among free-roaming ungulates based on species, literature type, and data source. Among the 18 identified ungulate hosts, moose, white-tailed deer (<i>Odocoileus virginianus</i>), and elk (<i>Cervus canadensis</i>) were most frequently reported. We observed a higher Eco-IV for moose, indicating an abundance of species-specific information, and a lower Eco-IV (less information available) for methods focusing on white-tailed deer. Limited sample sizes prevented the identification of patterns of knowledge acquisition for elk. Eco-IVs in other ungulate species were consistently lower than moose, white-tailed deer, and elk, regardless of literature type or data source. Exotic and invasive species systematically lacked detailed methods (Eco-IV = 0). These findings highlight significant information gaps that impede the ability to compare winter tick infestation rates across studies, geographic regions, and host species, thus hindering coordinated management actions.

The objective of this study was to determine whether baiting, which is widely conducted in Canada and the United States as part of waterfowl management practices (e.g., duck banding), influences the occurrence of avian influenza virus (AIV) in wetlands. We used a quasi-experimental design, collecting superficial sediment samples (<i>n</i> = 336) and fecal samples (<i>n</i> = 242) from paired baited (treatment) and non-baited (control) sites at 2 wetlands in Saskatchewan, Canada, between August and September 2022. We visited sampling sites 3 times during the sampling period: prior to the commencement of baiting activities (<i>t0</i>), approximately 14 days after <i>t0</i> (<i>t1</i>), and 24 days after <i>t0</i> (<i>t2</i>). We screened samples for AIV using real-time reverse-transcriptase polymerase chain reaction (rRT-PCR) targeting the matrix gene and subjected the PCR-positive samples to next-generation sequencing. We used a mixed-effects logistic regression model to estimate the effect of baiting on the odds of AIV positivity in sediment samples, while controlling for clustering by wetland. At control sites, we did not detect evidence for a difference in the odds of AIV detection in sediment at <i>t1</i> or <i>t2</i> versus <i>t0</i>; however, at baited sites, the odds of AIV detection at <i>t1</i> were 5.43 (95% CI = 1.99, 14.79) times the odds at <i>t0</i> and at <i>t2</i> the odds of AIV detection were 8.73 (95% CI = 3.29, 23.18) times the odds at <i>t0</i>. We detected HPAIV clade 2.3.4.4b H5N1 in sediment at 1 treatment site following baiting. There was also a trend towards increased fecal AIV positivity and increased fecal and sediment AIV diversity in baited versus non-baited sites; however, there was insufficient power to determine if these findings were statistically significant. Overall, our results indicate that baiting is associated with localized increases in AIV environmental contamination, with baiting potentially creating concentrated areas of AIV accumulation. As such, wetland baiting activities may pose a risk to wildlife population health through the propagation of AIV in wetlands and the waterfowl using those environments and efforts to replace, refine, or reduce this activity may be warranted depending on local ecosystem contexts and cost-benefit analyses.</p>","PeriodicalId":17504,"journal":{"name":"Journal of Wildlife Management","volume":"89 3","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/jwmg.22720","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143594860","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}

Game species encounter dynamic risks during hunting season as ephemeral predators (i.e., hunters) alter the predation risk landscape daily and seasonally. Predators and prey often concentrate around food sources during hunting season, further complicating the balance of energy intake and risk minimization for prey species. For example, many wetland managers provide energy-rich food resources, such as unharvested grain, that attract waterfowl. Hunter access to these areas varies and alters the inherent risk that wintering waterfowl face to use these resources. We hypothesized use and subsequent depletion of unharvested flooded corn fields would be influenced by proximate anthropogenic disturbance and predation risk, shifting the bioenergetic landscape for waterfowl. We first sampled 145 unharvested flooded cornfields under different hunting access regimes to estimate corn biomass in October 2019 and 2020 in western Tennessee, USA. We then returned to 30 of those fields biweekly during fall-winter 2019–2021 to estimate depletion rates in 60 fields. We modeled depletion rate as a function of hunting risk and forage accessibility by including the variables of corn ear height above water surface, field size, field ownership type, and field distance from sanctuary in our statistical model. Biomass estimates derived from initial surveys indicated private fields that were hunted provided the greatest corn biomass (7,134 ± 448 kg/ha), followed by public fields that were hunted (5,272 ± 320 kg/ha) and finally sanctuaries closed to hunting (3,995 ± 371 kg/ha). Corn biomass was depleted 2–4 times faster on sanctuaries than on hunted fields during November and December but 2 times faster in hunted fields than in sanctuary fields in January. Depletion rates increased as surface water came closer to corn ears but were unaffected by field size or field distance from unhunted sanctuary. Sanctuary fields were devoid of corn by the end of January, whereas 55% of public and 50% of private hunted fields still had corn remaining on 15 March, by which time most ducks had likely initiated migration. Private lands sampled in 2020 contributed nearly 7 times more energy than assumed in the 2015 Lower Mississippi Alluvial Valley Joint Venture energetic allocation models. Despite being devoid of hunters at night, hunted lands are not perceived by foraging waterfowl to be nocturnally similar to sanctuary areas during hunting season. In turn, hunted fields were exploited by ducks later in the season when sanctuary resources were scarce, providing available biomass for migrating birds. It may be important for managers to retain water on hunted fields through early spring given the lack of energy-dense foraging resources available on sanctuary areas.

However, these contemporary forests have smaller patch sizes, putting humans in closer proximity to previously remote forested areas, and different species compositions and structure compared to historical forests. These conditions pose an increased risk of exposure to anthropogenic disturbances and contaminants for forest-dwelling wildlife. We evaluated the relationship between contemporary forest conditions and anticoagulant rodenticides (ARs) on recent population trends for fishers (<i>Pekania pennanti</i>). We acquired a snapshot of recent population trends for fishers across New York, Vermont, and New Hampshire, USA, using standardized catch-per-unit-effort (CPUE) data from the regulated fall harvest spanning 2016-2020, when harvest regulations remained consistent across the states. We used regression models to relate the probability of CPUE increase to measures of forest habitat (age, structure, productivity), length of winter snow cover, and human disturbance (land use patterns and AR detection). The top model indicated that the probability of CPUE increase declined 43% for every 10% increase in the percent of the population exposed to at least 1 AR and by 24% for every 1-day increase in the length of winter snow cover, while measures of forest conditions had no significant relationship. The relationship between AR detection and suppressed CPUE increase is compelling, as few mammalian studies effectively link the detection of AR residues in animal tissues to population-level performance in the wild. Nevertheless, longer time frames are required to fully understand population trends and their drivers across heterogeneous landscapes.

Understanding how pathogens spread through wildlife populations requires information about animal space use across the landscape. The abundance of bighorn sheep (<i>Ovis canadensis</i>) in western North America has declined in response to pathogens introduced concurrently with the expansion of domestic sheep. Wildlife and land management agencies use bighorn sheep seasonal home range models to assess and mitigate pathogen transmission risk among bighorn and domestic sheep populations. Current risk assessment tools assume that seasonal home ranges are annually consistent, but the extent to which deviations from this assumption could render erroneous predictions about pathogen introduction risk has not received extensive attention. To evaluate the influence of temporally variable environmental conditions on pathogen introduction risk, we used locations of desert bighorn sheep (<i>O. c. nelsoni</i>) gathered across 6 populations residing in the Mojave Desert, an environment characterized by high interannual variation in precipitation and forage production. Our objectives were to assess whether seasonal home range sizes varied consistently with temporally varying attributes of the environment and assess the influence of varying environmental attributes on pathogen introduction risk using our model results and the United States Forest Service's Risk of Contact (ROC) tool. Home range sizes varied by sex and season, with higher environmental moisture levels (Palmer drought severity index) associated with larger male home ranges in summer and fall-winter. Higher spatial variation in primary productivity was associated with smaller male home range sizes in summer but with larger male home range sizes in fall-winter. Female home ranges were also smaller when variation in primary productivity was high during spring but had no detectable relation with environmental moisture or spatial variation in productivity during the rest of the year. We combined these results with the ROC tool to simulate the influence of varying environmental attributes on pathogen introduction risk. Those simulations suggested that home range expansions associated with above-average environmental moisture only increased the contact risk between 2 adjacent populations by 0.02%. Consequently, risk forecasts in the Mojave Desert system might be relatively robust to temporally dynamic home range sizes, so long as the environmental attributes driving home range size do not deviate dramatically from historical levels. However, major departures from long-term trends in environmental variation could lead to more dramatic effects on home range size and subsequent risk and should be reassessed if environmental variation changes substantially in the future.</p>","PeriodicalId":17504,"journal":{"name":"Journal of Wildlife Management","volume":"89 3","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143595447","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}
