Environmental DNA, Volume 7, Issue 6, November–December 2025.In this study, we provide the first comparison of airborne eDNA with observer‐based surveys and passive acoustic monitoring, alongside camera traps, to monitor birds and mammals in a Dutch agroforestry system. Airborne eDNA showed the highest potential species diversity, detected many unique species–including invasive mammals–and complemented ...

The Journal of Wildlife Management, Volume 89, Issue 8, November 2025.We incorporated landscape suitability into a trumpeter swan range expansion model. We estimated a 4.4% (95% CI: 2.0–6.9%) annual range expansion rate from 2023 to 2033, with expansion occurring in the Prairie Pothole Region of the Dakotas and the Boreal Shield and James Bay Lowlands of Canada. Abstract The Interior Population of trumpeter swans (Cygnus

Solar Radiation Affects Bird Distributions but Not Elevational Shifts in European Mountains
Global Ecology and Biogeography, Volume 34, Issue 11, November 2025.ABSTRACT Aim Climate change is driving species towards higher elevations. While local shifts in elevation are well documented, patterns across entire mountain regions are less understood. On a local scale, abiotic factors, such as topography and solar radiation relating to microclimate, affect species distributions and can thus influence the rate of ...

Quantification of avian hazards to military aircraft and implications for wildlife management. [PDF]
PLoS ONE, 2018 Collisions between birds and military aircraft are common and can have catastrophic effects. Knowledge of relative wildlife hazards to aircraft (the likelihood of aircraft damage when a species is struck) is needed before estimating wildlife strike risk (

On the Japan-taken Branta canadensis
Japanese Journal of Ornithology, 1952 I reported a specimen of Branta taken in Japan preserved in the British Museum of Natural History, London and identified it with some doubt to be Branta minima (cf. Tori, no. 26, pp. 2-3, 1928). Recently Mr. Robert A. Coombes of Tring Museum kindly examined this skin (Brit. Mus. Reg. 1894. 8. 12. 24) on my behalf and informed that it belongs to B.

Evidence of territoriality and species interactions from spatial point-pattern analyses of subarctic-nesting geese. [PDF]
PLoS ONE, 2013 Quantifying spatial patterns of bird nests and nest fate provides insights into processes influencing a species' distribution. At Cape Churchill, Manitoba, Canada, recent declines in breeding Eastern Prairie Population Canada geese (Branta canadensis ...
