We investigated survival, home-range size, and habitat selection of female Bachman's Sparrows during the breeding season at Fort Bragg Military Installation, NC. We attached radio-transmitters to female sparrows between April and June in 2014–2016 and recorded locations of females every 2–4 days. We estimated seasonal survival and home-range size and, in 2016, we modeled habitat selection of female sparrows within their home range. Estimated breeding-season (90 days) survival (0.941) was greater than a published estimate from South Carolina (0.794), and home-range size (1.48 ha, SE = 0.16) was similar to a published estimate for females and multiple published estimates for male sparrows (min–max = 1–5 ha). Females selected habitat patches with greater woody vegetation and intermediate grass densities than at random locations, suggesting that woody vegetation provides escape and nesting cover for female sparrows. Survival, home-range size, and habitat selection of female Bachman's Sparrows did not differ substantially from males in other studies. Therefore, management focused on male sparrows may concurrently conserve habitat requirements for females.}, number={1}, journal={SOUTHEASTERN NATURALIST}, publisher={BioOne}, author={Choi, Daniel Y. and Fish, Alexander C. and Moorman, Christopher E. and DePerno, Christopher S. and Schillaci, Jessica M.}, year={2021}, month={Mar}, pages={105–116} } @article{vayer_larson_peterson_lee_von furstenberg_choi_stevenson_ahlers_anhalt‐depies_bethke_et al._2021, title={Diverse University Students Across the United States Reveal Promising Pathways to Hunter Recruitment and Retention}, volume={85}, ISSN={0022-541X 1937-2817}, url={http://dx.doi.org/10.1002/jwmg.22055}, DOI={10.1002/jwmg.22055}, abstractNote={Declining participation in hunting, especially among young adult hunters, affects the ability of state and federal agencies to achieve goals for wildlife management and decreases revenue for conservation. For wildlife agencies hoping to engage diverse audiences in hunter recruitment, retention, and reactivation (R3) efforts, university settings provide unique advantages: they contain millions of young adults who are developmentally primed to explore new activities, and they cultivate a social atmosphere where new identities can flourish. From 2018 to 2020, we surveyed 17,203 undergraduate students at public universities across 22 states in the United States to explore R3 potential on college campuses and assess key demographic, social, and cognitive correlates of past and intended future hunting behavior. After weighting to account for demographic differences between our sample and the larger student population, 29% of students across all states had hunted in the past. Students with previous hunting experience were likely to be white, male, from rural areas or hunting families, and pursuing degrees related to natural resources. When we grouped students into 1 of 4 categories with respect to hunting (i.e., non-hunters [50%], potential hunters [22%], active hunters [26%], and lapsed hunters [3%]), comparisons revealed differences based on demographic attributes, beliefs, attitudes, and behaviors. Compared to active hunters, potential hunters were more likely to be females or racial and ethnic minorities, and less likely to experience social support for hunting. Potential hunters valued game meat and altruistic reasons for hunting, but they faced unique constraints due to lack of hunting knowledge and skills. Findings provide insights for marketing and programming designed to achieve R3 objectives with a focus on university students. © 2021 The Wildlife Society.}, number={5}, journal={The Journal of Wildlife Management}, publisher={Wiley}, author={Vayer, Victoria R. and Larson, Lincoln R. and Peterson, M.

Gastrointestinal tracts were examined from 464 green turtles that stranded in Texas between 1987 and 2019, and 226 turtles ingested plastic (48.7%). This number doubled from 32.5% in 1987-1999 to 65.5% in 2019, but mass of ingested items was lowest in 2019. No turtles showed evidence of death directly related to plastic ingestion. Compared to other regions, plastic ingestion was low. Small turtles (<25 cm straight carapace length) ingested plastic more frequently and in greater amounts than larger turtles. Small turtles also ingested more hard plastic while larger turtles ingested more sheet-like and thread-like plastics, which may correspond to size-based habitat shifts. This is among the largest marine turtle ingestion studies to date and demonstrates an increasing prevalence of plastic ingestion.}, journal={MARINE POLLUTION BULLETIN}, author={Choi, Daniel Y. and Gredzens, Christian and Shaver, Donna J.}, year={2021}, month={Dec} } @article{larson_peterson_furstenberg_vayer_lee_choi_stevenson_ahlers_anhalt-depies_bethke_et al._2021, title={The future of wildlife conservation funding: What options do US college students support?}, volume={3}, url={https://doi.org/10.1111/csp2.505}, DOI={10.1111/csp2.505}, abstractNote={Insufficient funding is a major impediment to conservation efforts around the world. In the United States, a decline in hunting participation threatens sustainability of the “user-pay, public benefit” model that has supported wildlife conservation for nearly 100 years, forcing wildlife management agencies to contemplate alternative funding strategies. We investigated support for potential funding options among diverse college students, a rapidly expanding and politically active voting bloc with a potentially powerful influence on the future of conservation. From 2018 to 2020, we surveyed 17,203 undergraduate students at public universities across 22 states. Students preferred innovative approaches to conservation funding, with 72% supporting funding derived from industry sources (e.g., natural resource extraction companies), 63% supporting state sources (e.g., general sales tax), and 43% supporting conventional user-based sources such as license fees and excise taxes associated with outdoor recreation activities (e.g., hunting).

Researchers and managers have made major efforts to chronicle bird and bat mortality associated with wind facilities, but few studies have examined the patterns and underlying mechanisms of spatial patterns of fatalities at wind facilities. Understanding the horizontal fall distance between a carcass and the nearest turbine pole is important in designing effective search protocols and estimating total mortality. We explored patterns in taxonomic composition and fall distance of bird and bat carcasses at wind facilities in the Northeastern United States using publicly available data and data submitted to the US Fish and Wildlife Service under scientific collecting and special purpose utility permits for collection and study of migratory birds. Forty-four wind facilities reported 2,039 bird fatalities spanning 128 species and 22 facilities reported 418 bat fatalities spanning five species. Relative to long-distance migratory birds, short-distance migrants were found farther from turbines. Body mass of birds and bats positively influenced fall distance. Turbine size positively influenced fall distance of birds and bats when analyzed collectively and of birds when analyzed separately from bats. This suggests that as turbines increase in size, a greater search radius will be necessary to detect carcasses. Bird and bat fall distance distributions were notably multimodal, but only birds exhibited a high peak near turbine bases, a novel finding we attribute to collisions with turbine poles in addition to blades. This phenomenon varied across bird species, with potential implications for the accuracy of mortality estimates. Although pole collisions for birds is intuitive, this phenomenon has not been formally recognized. This finding may warrant an updated view of turbines as a collision threat to birds because they are a tall structure, and not strictly as a function of their motion.}, number={8}, journal={PLOS ONE}, publisher={Public Library of Science (PLoS)}, author={Choi, Daniel Y. and Wittig, Thomas W. and Kluever, Bryan M.}, editor={Magar, VanesaEditor}, year={2020}, month={Aug} }
