Landscape distribution and habitat use of sika deer using indirect signs of deer activity: a simple tool for forest managers

open access: yesWildlife Biology, Volume 2026, Issue 5, September 2026.
The populations of many deer species across Europe are widely reported to be increasing, leading to potentially greater impacts on forest ecosystems. Our understanding of factors driving the regional distribution (e.g. 1 km2 resolution) of deer populations is, however, often limited by a lack of knowledge of where deer are within the landscape.

Ecology of declining populations of gray foxes (Urocyon cinereoargenteus) in Indiana, USA Ecología de las poblaciones en declive de zorros grises (Urocyon cinereoargenteus) en Indiana, EE.UU.

open access: yesWildlife Monographs, Volume 226, Issue 1, September 2026.
We estimated seasonal space use, cover selection, and resource selection; evaluated gene flow and potential genetic barriers; and assessed cause‐specific survival rates and reproduction of radiomarked gray foxes in Indiana, USA. Our results provide evidence that gray foxes in Indiana are an edge species with relatively large home ranges, relatively low
