This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Juvenile survival may be the most critical component of large herbivore population growth, but how neonate survival changes over time and space is not fully understood. Neonate survival rates are influenced by maternal care, site-specific differences, and are generally characterized by year-to-year variation. Sources of white-tailed deer (Odocoileus virginianus) fawn mortality across North America include predation, natural causes (excluding predation), and both direct and indirect human-caused mortality. The relative frequency of these causes indicates which sources most affect neonate survival and can be easily compared among studies. We used a meta-analysis approach to elucidate spatial patterns in fawn survival at a landscape-scale across North America. However, comparing survival rates across time is not possible when confounded by spatial variation. Therefore, we investigated how fawn survival varied across time by conducting a neonate survival study in central Pennsylvania to compare a current estimate of neonate survival to previous estimates for central Pennsylvania in 20002001. Furthermore, because pre-weaned neonates (

This book was released on 2016 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Survival of white-tailed deer (Odocoileus virginianus) fawns has declined in some areas of the southeastern U.S areas, and changing predator communities may complicate deer management scenarios. During 2013-15, I monitored survival of fawns and adult females on Tensas River National Wildlife Refuge (TRNWR), Louisiana. I determined cause-specific mortality and investigated variables influencing fawn survival. I used site-specific vital rates to model population trajectories and explored potential effects of changes in fawn and adult survival rates. Predation by black bear (Ursus americanus) was the greatest source of fawn mortality but appears to be partitioned with predation from other species. Fawn survival was positively correlated with birth mass and closer proximity to older reforestation sites but negatively correlated with proximity to young reforestation and cropland. Under current harvest guidelines and observed fawn survival rates, deer populations on TRNWR are sustainable, but reductions in female harvest could be considered if fawn survival decreases.

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Mule deer (Odocoileus hemionus) and white-tailed deer (O. virginianus) are common sympatric deer species in the Great Plains and western United States that have exhibited divergent population trends temporally and spatially. Mule deer populations are declining and contracting to the west while white-tailed deer populations are expanding. Species-specific differences in fawn recruitment is one proposed explanation for these observed trends, although the underlying causes remain unknown. To determine if landscape or other habitat changes are affecting the two deer species in different ways, we studied bed-site selection of mule deer and white-tailed deer fawns in western Kansas at microhabitat and landscape scales. We also assessed how fawn intrinsic factors, doe maternal condition, and bed-site habitat characteristics influenced survival of mule deer and white-tailed deer fawns. In February 2018 and 2019, we captured 120 adult does (60 mule deer, 60 white-tailed deer) using helicopter net-gun techniques and deployed 120 vaginal implant transmitters (VITs) synchronized with GPS collars deployed on does. Upon VIT expulsion, a birthing event notification was triggered, which narrowed search efforts for fawns. We captured and radio-collared 100 fawns (53 mule deer, 47 white-tailed deer) during 12 May- 23 June in 2018 and 2019. Fawns were visually located daily using ground-based radio-telemetry and we assessed bed-site selection, cause-specific mortality, and survival rates until fawns reached 10 weeks of age. Overall, fawn survival was low (0.32 ± 0.06) and did not differ between species (mule deer: 0.25 ± 0.08; white-tailed deer: 0.41 ± 0.08). Adult chest girth was positively associated with 70-day white-tailed deer fawn survival, longer fawn body length increased 7-day white-tailed deer fawn survival, and fawn sex best predicted 7-day mule deer fawn survival. Model uncertainty indicated fawn intrinsic factors and maternal conditions may be poor predictors of fawn survival. White-tailed deer survival was lower for fawns with more woodland in their home ranges and mule deer fawn survival exhibited a positive quadratic relationship with the amount of grassland within the home range. Mule deer fawn survival increased with the amount of edge and disaggregation within a home range, but landscape configuration did not explain survival of white-tailed deer fawns. We analyzed microhabitat characteristics at 2689 fawn bed-sites and 2689 paired random points. Bed-site selection differed by species; however, vegetative structure was the most influential microhabitat characteristic for both deer species. Mule deer fawns selected for 75% visual obstruction 8.4 dm tall, less grass cover, more succulent cover, and 56% shrub cover at bed-sites. White-tailed deer fawns selected for 25% visual obstruction 9.2 dm tall, 71% forest canopy cover, and less grass cover and bare-ground at bed-sites. The two species also showed differences in landscape selection. The odds of a white-tailed deer fawn bed-site increased 5.88 times in woodlands, whereas odds of a mule deer fawn bed-site increased 2.85 times in CRP. Our research suggests white-tailed deer fawns and mule deer fawns selected different characteristics for bed-sites at the microhabitat and landscape scale. Bed-site selection likely influences fawn survival, which could affect fawn recruitment. Managers should focus on maintaining heterogeneous landscapes composed mainly of native and Conservation Reserve Program grasslands with abundant cover to enhance mule deer fawn survival and bolster adult populations.

This book was released on 2018 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: I monitored cause-specific mortality and factors influencing mortality risk for white-tailed deer in the Upper Peninsula of Michigan, USA, during two high mortality risk periods: adult female deer during Feb–May, and fawns from birth to 6 months. I observed high rates of predation and starvation for adult female deer during Apr–May, suggesting that late winter represents a survival bottleneck due to nutritional declines. A strong negative relationship existed between snow free days during late winter and mortality risk. Predation was the dominant mortality source for fawns but predation risk decreased with larger birth mass. Black bears and coyotes accounted for most fawn kills at the population level, but wolves and bobcats had greatest per-individual fawn kill rates. My results suggest predation was the dominant mortality source for fawns and adult female deer, but multiple predator species were important and nutritional condition of deer influenced their vulnerability to predation.

This book was released on 2018 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chapter 1 of this dissertation examines survival of subadult male white-tailed deer (Odocoileus virginianus) in southern Delaware. Increasing male age structure in white-tailed deer populations has become an important objective for many state managers and private landowners seeking to improve hunter satisfaction while maintaining appropriate deer densities. Limiting mortality in the subadult age class is often the primary consideration, and regional differences in climate, habitat, regulations, and hunter behavior complicate understanding of how specific factors influence the risk of mortality. I used Cox proportional hazard modeling to examine the effects of mean distance to road, mean distance to habitat edge, dispersal behaviors, and landownership on the risk of mortality of a collared population of subadult males (n = 61) in Sussex County, Delaware, USA. Annual survival averaged 0.60 (95% confidence interval = 0.49 – 0.73), with hunter harvest accounting for 79% of all mortalities. The best approximating supported model for risk of mortality included covariates for landownership (public versus private; P
