Seasonal variations and challenges in estimating populations and identifying species of Korean ungulates using drone‐derived thermal orthomosaic maps

Wildlife Biology, Volume 2026, Issue 5, September 2026.
Drones equipped with thermal infrared (TIR) cameras offer significant time and labor savings in estimating wild ungulate populations. However, accurately monitoring forest‐dwelling ungulates remains challenging due to their elusive behavior and complex habitat.

Estimating red deer Cervus elaphus population density using drones in a steep and rugged terrain

Wildlife Biology, Volume 2026, Issue 5, September 2026.
Precise and accurate information about population density, crucial for wildlife management, is difficult to obtain for elusive species living in dense forests or steep and inaccessible terrain. Using unmanned aerial vehicles (UAVs), we developed a method for obtaining absolute population estimates of ungulates living in steep, rugged, and partly ...

Experimental assessment of large mammal population estimates from airborne thermal videography

Wildlife Biology, Volume 2026, Issue 5, September 2026.
Wildlife resource management requires reliable, fast, and affordable methods of surveying wildlife populations to develop and adaptively adjust policies. Thermal video from drones can yield high rates of detection over large areas with relative speed and safety.

Exploring sources of uncertainty in the estimate of waterfowl harvest in the United Kingdom

Wildlife Biology, Volume 2026, Issue 5, September 2026.
There is an urgent need to gather data on harvest rates of waterbirds in Europe to assess the sustainability of hunting. Estimates of total waterbird harvest in the United Kingdom (UK) and the relative harvest of different huntable species come from two separate surveys, the Value of Shooting (PACEC 2014) and National Gamebag Census (NGC), and these ...

Availability bias and responsive movement during ground‐based wildlife surveys revealed by concurrent thermal drone surveys

Wildlife Biology, Volume 2026, Issue 5, September 2026.
Methods to estimate abundance from unmarked populations of animals are widely used because of their efficiency and presumed accuracy. These methods account for imperfect detection by comparing observed data against the assumed distribution of the entire population.

Thermal‐UAV assisted detection and relocation of roe deer fawns in managed grasslands

Wildlife Biology, Volume 2026, Issue 5, September 2026.
Advancements in modern fodder production have unintentionally increased wildlife mortality during grass mowing operations. Roe deer Capreolus capreolus fawns are particularly vulnerable because they remain motionless as a predator‐avoidance strategy. Unmanned aerial vehicles (UAVs) equipped with thermal sensors offer a promising method for detecting ...

Heathland pollinator communities are more strongly influenced by land management than by honeybee competition

Journal of Applied Ecology, Volume 63, Issue 9, September 2026.
Apiaries had modest impacts on heathland plant–pollinator communities, likely buffered by the abundance of Calluna vulgaris which provides 91% of landscape nectar during hive introductions. We recommend avoiding hive introductions outside of peak flowering periods and managing grazing in the spring to ensure nectar resources for emerging pollinators ...

First record of the forensically important genus Protopiophila Duda (Diptera: Piophilidae) from South Korea and an integrative framework for forensic identification

Journal of Forensic Sciences, Volume 71, Issue 5, Page 2405-2414, September 2026.
Abstract The family Piophilidae is of significant forensic importance due to its association with late‐stage decomposition; however, the Korean piophilid fauna remains poorly studied, lacking comprehensive morphological and molecular data. This study reports the first record of the genus Protopiophila Duda from South Korea.

Pollinator Associations of Rare and Endangered Epacris Species (Ericaceae) in Lutruwita/Tasmania: Implications for Conservation

Austral Ecology, Volume 51, Issue 9, September 2026.
ABSTRACT The breeding systems of Lutruwita/Tasmania's threatened Epacris taxa are poorly known. Our main objective was to determine the pollinators of several endemic species and explore for relationships between pollinators, floral morphology, flowering time and habitat. The Epacris have limited variation in floral traits and exhibit generalist floral

Water Beings and Capitalist Relations in India's Sundarbans Delta

American Anthropologist, Volume 128, Issue 3, Page 595-606, September 2026.
ABSTRACT This article explores entanglements between water cosmologies and capitalist transformation in the Sundarbans delta of West Bengal, India. It traces how “awakened” tidal creeks have been iteratively enclosed as private fisheries from the colonial period to the present, with particular focus on the expansion of commercial aquaculture over the ...
