Effects of selective harvest on antler size of white‐tailed deer in Texas, USA

Wildlife Monographs, Volume 222, Issue 1, June 2026.
We conducted 20 years of experiments on the selective harvest of white‐tailed deer by antler size, judged inferior, in 2 areas of South Texas, USA. Selective harvest increased the phenotypic antler size of older males in one study area but not the other. There was little evidence of evolution resulting from selective harvesting. Abstract There has been

Spatially Downscaling of Future Food Demand for Policy Planning

World Food Policy, Volume 12, Issue 1, May 2026.
ABSTRACT Understanding the subnational dynamics of food demand, while accounting for the evolution of the agrifood system at the global level, remains a challenge for designing food policy to ensure food security. To link global agrifood systems with subnational food policy planning, we downscale per capita food demand for 62 food commodities at the ...

Acclimatisation duration, not just release type, drives post‐release settlement in a large‐scale carnivore reintroduction programme

Journal of Applied Ecology, Volume 63, Issue 5, May 2026.
Our study highlights that when acclimatisation periods are too short, the substantial economic and logistical investment in soft‐release protocols may fail to deliver the expected conservation gains. Therefore, defining evidence‐based acclimatisation periods that are long enough to promote settlement, yet compatible with logistical constraints, may ...
