This challenge is amplified for lizards in Aotearoa New Zealand, where they receive meager funding for conservation management and monitoring. Regardless, long-term monitoring is required to inform population trends, the impact of threats, and the effect of any subsequent management. Lakes skinks (<i>Oligosoma</i> aff. <i>chloronoton</i> “West Otago”) are large ground-dwelling skinks currently classed as Threatened – Nationally Vulnerable in Aotearoa New Zealand, though little is known regarding this species' trajectory. We compiled 9 years (2017–2025) of monitoring data from a population of Lakes skinks. The first 8 years of monitoring failed to reveal a clear trend in abundance. To resolve this problem, in 2025 we doubled survey effort for the population, resulting in a more precise estimate of abundance that indicated that the population is small and may be declining. However, this methodology is not guaranteed to generate equally precise estimates in the future, particularly because we observed declining capture rates within annual effort. We suggest that survival rates generated using between-year mark-recapture (photo-ID) could provide an alternative framework by which to track the population and justify management. Producing highly precise estimates of population abundance is inherently difficult and may be impossible given current resource limitations for species that are not prioritized for active management. We suggest that there is not one ubiquitous solution to this problem and that constant assessment of whether a monitoring regime is fit for purpose is required so that effort is not wasted.</p>","PeriodicalId":17504,"journal":{"name":"Journal of Wildlife Management","volume":"90 3","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147563831","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}

Managing feral swine on private lands is increasingly necessary to reduce ecological and economic damage. Management is also becoming increasingly challenging with growing swine populations and the diversity of private ownership and management objectives. To improve feral swine management, we conducted a mail survey of landowners to better understand private landowners’ feral swine management decision-making in Arkansas, Louisiana, and East Texas, a region that contains over half of the feral swine population in the United States. We documented reported management actions and motivations, described perceived effectiveness of different management strategies, and examined various factors related to landowners’ decisions to manage swine. We used analysis of variance to test differences in swine management and control activities among the 3 states and binary logistic regression to identify factors associated with landowners’ swine management decisions. Shooting and trapping activities were conducted more often than other activities (e.g., fences, repellent usage). Regression results indicated that landowner decisions to manage feral swine were related to sociodemographic characteristics (age, education) and property size, familiarity with and beliefs about feral swine impacts, and perceptions of neighbors and community. These findings offer insights into feral swine management decision-making and can facilitate the development of incentives, education, and outreach programs that encourage landowners to manage feral swine in the West Gulf Region.</p>","PeriodicalId":17504,"journal":{"name":"Journal of Wildlife Management","volume":"90 3","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147570029","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}

Earlier tests detected no negative effects on dabbling duck physiology and behavior, but the potential deleterious effect on annual survival probability remained to be evaluated. We relied on multistate capture-mark-recapture models applied to 11,874 Eurasian teal (<i>Anas crecca</i>) banded in France from 2002 to 2021, of which 308 were recaptured alive at least once and 1,390 yielded dead band recoveries. Of the banded individuals, 6,770 teal (57.0%) were also marked with a plastic nasal saddle to evaluate the cost-benefit trade-off of the technique. Saddled teal had a lower annual survival probability (ranging from 0.30 ± 0.02 [SE] in hatch-year females to 0.45 ± 0.02 in after hatch-year males) than banded-only individuals (0.44 ± 0.03 to 0.53 ± 0.02). Incorporating live nasal saddle resighting information in life histories of the individuals did not improve precision of annual survival probability estimates. The mechanism behind such reduced annual survival remains unclear, and a potential greater influence of hunting on saddled birds cannot be excluded, either through greater exposure to hunting owing to birds’ behavior or through greater targeting by hunters. In any case, there were clear drawbacks to bird survival, with very limited benefits for the biologists, so this technique should be abandoned when the unique goal of fitting nasal saddles is to evaluate long-term demographic parameters in dabbling ducks. The method could remain valuable for other purposes such as shorter-term monitoring of brood-rearing females, evaluation of stopover duration, or some migration studies, but even then, results should be interpreted with caution and animal welfare issues should be considered.</p>","PeriodicalId":17504,"journal":{"name":"Journal of Wildlife Management","volume":"90 3","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147567664","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}

Sea duck hunters participating in federal harvest surveys represent a small proportion of the overall waterfowl hunting population, limiting the utility of harvest estimates for sea ducks. The long-tailed duck (<i>Clangula hyemalis</i>) is one such species. To partially address the paucity of long-tailed duck harvest survey information, we conducted in-person hunter surveys from 1 November through 4 December 2016 at a boat launch in Two Rivers, Wisconsin, USA (Lake Michigan), an important area for long-tailed duck harvest within the state. Hunters were present on 15 of 21 survey days, and we surveyed occupants of 62 individual hunting boats on 127 occasions. Long-tailed ducks were the most common (97%) of the 1,431 sea ducks reported harvested by hunters. Hunter harvest of long-tailed ducks averaged 3.8 (95% CI = 3.4, 4.1; range = 0–6) long-tailed ducks/hunter/day. We used count models to evaluate the effects of environmental variables on hunter participation and harvest of long-tailed ducks. Wave height was the most influential predictor variable for hunter participation; an information criterion-based best model (wave height + temperature) indicated that hunter participation decreased by 91.9% (95% CI = 79.3–97.1%) for each 1-m increase in wave height. Long-tailed duck harvest was positively associated with air temperature; the relationship indicated a 9.5% (95% CI = 6.2–12.9%) increase in long-tailed duck harvest with each degree increase in temperature. Our results contribute to the understanding of waterfowl hunter participation, hunter preferences, and harvest on Lake Michigan and can inform managers as they assess regulatory frameworks for sea duck hunting.</p>","PeriodicalId":17504,"journal":{"name":"Journal of Wildlife Management","volume":"90 3","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147569721","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}

Diving duck species use distinct habitats, exploit unique resources, and can collectively provide an integrated index of winter habitat quality. The San Francisco Bay (SFB) is the largest estuary on the west coast of North America, serving as critical wintering habitat for diving ducks in the Pacific Flyway. To evaluate the body condition of diving ducks after multiple decades of tidal habitat restoration in SFB, we compared structurally corrected measurements (annual and decadal) of total carcass lipid among canvasback (<i>Aythya valisineria</i>), greater scaup (<i>Aythya marila</i>), lesser scaup (<i>Aythya affinis</i>), and ruddy duck (<i>Oxyura jamaicensis</i>). We found greater and lesser scaup gained lipid reserves within the estuary prior to spring migration; however, canvasback and ruddy duck lipid levels declined throughout the winter and into the spring. Lipid loss over the wintering period could indicate a reduction in foraging resource availability, dietary shifts, or metabolic changes. These deficiencies could have negative cross-seasonal implications, as these species must accumulate resources outside of their wintering areas to fuel migration and reproduction. Lipid levels were elevated in lesser scaup collected in 2017-2019 compared to 1998-2000, while we found no decadal differences in lipid levels for canvasback or greater scaup.

Access to PAFS can drive population increases in certain species, producing cascading effects that may directly or indirectly affect others, including species already in decline or of conservation concern. We studied the effect of PAFS in a Protected Area in Costa Rica, Parque Nacional Marino Las Baulas (PNMB), which was established to protect sea turtles. We quantified urban growth since the Park was established, assessed the effects of PAFS in trash containers on the presence and activity of wildlife species, and evaluated the increase in sea turtle nest predation over time. Since the Park was established (1991), there has been a &gt; 10-fold increase in the number of buildings in the area, mainly within its buffer zone. We identified 8 native species extracting food from garbage containers at PNMB, with northern raccoons (<i>Procyon lotor</i>) comprising most detections (84%), and 4 other species that are potential predators of sea turtle eggs. The number of detections and access to garbage containers was influenced by location and type of container. Areas with more development had more wildlife detections around garbage containers. Additionally, the percentages of sea turtle clutches predated and clutches that were relocated to avoid predation increased since predation was first monitored in the 2011–2012 nesting season. We hypothesized that urban development promoted PAFS at PNMB, possibly increasing the number of raccoons, which in turn, increased predation of sea turtle nests.

Inter-annual population changes from roadside surveys have occasionally implied biologically implausible outcomes, hinting at survey bias and constrained utility of the index under certain environmental conditions. Research has shown correlations between environmental conditions and ring-necked pheasant detections but range-wide rigorous assessment of factors influencing detection probabilities has never been considered. We sought to evaluate environmental factors influencing detection probability of ring-necked pheasant broods across a large geographic scale, where August roadside surveys are an important monitoring tool. State wildlife resource agencies conducted 1,000 August roadside surveys on 174 unique route-by-year combinations in 11 states during 2019–2021. We used a single-species N-mixture model in a Bayesian framework to examine factors influencing detection probability of broods. Wind speed and cloud cover negatively influenced detection probability of pheasant broods. Dewpoint depression, a proxy for morning dew conditions where higher values indicate less dew, had a significant negative effect on detection probability for pheasant broods. Soil moisture had a positive effect on the detection probability of pheasant broods. Observed variation in conditions across routes, among the years in our study, and across the geographic scale covered could constrain direct comparisons of uncorrected counts. Survey methodology can be adjusted to target mornings with few clouds, low winds, and favorable dew conditions to increase detection probability and consistency among surveys. However, soil moisture may be difficult to methodologically control for over larger scales of space and time. Posterior estimates from our model may be used to gauge intra- and inter-seasonal variation in conditions for detecting pheasant broods, which could improve inference from long-term population monitoring, especially across large spatial and temporal scales.</p>","PeriodicalId":17504,"journal":{"name":"Journal of Wildlife Management","volume":"90 3","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://wildlife.onlinelibrary.wiley.com/doi/epdf/10.1002/jwmg.70180","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147566816","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}
