Summary: Predators can limit available habitat for prey. Habitat management to encourage spatial segregation of predators and prey can increase prey species abundance. The study found that bobwhite nests were more likely to be depredated in areas of high selection by coyotes and striped skunks.

Summary: Disruption of historic fire regimes has led to the expansion of hardwoods into pine savanna ecosystems in the southeastern United States. Management strategies that reduce mature mesophytic oaks in pine savanna may help restore understory vegetation and positively affect understory birds, but the impact on bobwhite survival and productivity remains inconclusive following hardwood reduction.

Summary: This study aimed to understand how raptors affect the survival of bobwhites, finding that raptors influence bobwhites in every biological season, especially in the breeding season and late winter. Even in areas with abundant habitat, predators exert top-down influences on vital rates.

Summary: This study investigates the impact of management strategies and land cover on the population dynamics of northern bobwhites. The findings suggest that environmental factors such as land cover composition, woody cover, and management actions influence the breeding season survival of both adult and nest bobwhites.

Summary: Despite the decline in Northern bobwhite populations across the United States, supplemental feeding remains a popular management method. However, the effectiveness of supplemental feeding practices is challenged by limited knowledge of the nutritional requirements of wild bobwhites.

Summary: Density dependence, immigration, and emigration have significant impacts on wildlife population demographics. A population simulation model can help predict the effects of management actions on population abundance, cumulative harvest, and extirpation risk. Incorporating these factors into models improves understanding of population dynamics and management effectiveness.

Summary: Understanding the effects of landscape management on northern bobwhite population growth requires comprehensive analysis of demographic parameters throughout the annual cycle. In this study, we evaluated the seasonal dynamics and population growth of bobwhites in Missouri and compared the differences between extensively and intensively managed sites. The results showed that extensively managed sites had higher nesting success and adult survival during the breeding season compared to intensively managed sites. However, both populations experienced decline from 2016 to 2019, indicating the need for further improvements in juvenile breeding season and non-breeding season survival.

Summary: Imprecise or biased density estimates can lead to inadequate conservation action or overexploitation of game species. Using correction factors for density calculations may reduce bias, but at the cost of lower precision compared to fully specified models.

Summary: The popularity of translocation as a conservation tool has increased due to the decline in the population of northern bobwhite. However, population sources are limited to a few areas in the United States. Understanding the demographic parameters of translocated individuals will help increase the effectiveness of translocation as a recovery tool.

Summary: Increased interannual weather variation due to climate change can have a significant impact on population dynamics of species, necessitating a comprehensive modeling framework to forecast future population dynamics incorporating weather scenarios and vital rate variation. Coupling an integrated population model with a population viability analysis can provide insights into population responses to weather, management, and changes in vital rates, serving as a tool for climate-informed management decisions.

Summary: The northern bobwhite is an ecologically and economically valuable species in the United States, with researchers using spatial capture-recapture methods to estimate population size and study spatial density variation. The study found that landscape structure significantly influenced density variations in bobwhite populations.

Summary: The study evaluated the thermal tolerance of northern bobwhite in southern Texas, USA, and identified the vegetation characteristics that create cooler microclimates for them. Results suggest that dense canopies, overlapping woody vegetation, and cooler temperatures have a significant influence on microsite selection by the birds.

Summary: The study found that northern bobwhites prefer nest sites with more woody understory and wiregrass cover, and closer distance to the nearest road. While prescribed burns are beneficial for conserving bobwhite habitat, burning during the nesting season may destroy nests and reduce nesting cover.

Summary: Grizzly bear sightings in northern Manitoba, Canada have increased over the past four decades, likely due to dispersal from established populations in Nunavut and the Northwest Territories. These sightings are concentrated in the Southern Arctic, Hudson Plains, and Taiga Shield ecozones within Manitoba. While grizzly bears were historically present in the area, their numbers were very low before 1980, and the frequency of observations has significantly increased since then. The data may have spatial and temporal biases, and the present population is likely maintained by dispersal from the north. Understanding grizzly bear ecology, distribution, and demographics in this region is crucial for accurately assessing their status and conservation needs in Manitoba.

Summary: Drone use in protected areas in North America has been increasing, but little is known about its potential impacts on terrestrial megafauna. This study evaluated the behavioral responses of feral horses and bison to drone flights at Theodore Roosevelt National Park in the United States. The results showed that both species displayed behavioral responses to the presence of the fixed-wing drone, but did not exhibit escape behaviors. The study also found that drone flights at 120 meters altitude did not elicit escape responses, indicating a low level of disturbance.

Summary: This study compared the behavioral responses of blue-winged teal and northern shovelers during UAV flights. The results showed that both species increased their time engaged in vigilance and left the wetland more frequently during flights. Blue-winged teal became less active, while northern shovelers became more active during this period. The launch distance was found to be the most important predictor of duck behavior.
