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

Predictive Models for Postfire Debris Flow Initiation in the Southwest USA
Abstract Postfire debris flows pose a threat to life and infrastructure and significantly contribute to sediment supply in upland channels, thereby impacting water quality, stream habitats, and landscape evolution. Models designed to assess postfire debris‐flow likelihood at the watershed scale in response to design or forecast rainstorms are ...

ABSTRACT Alien plant species are widely utilised for ornament, agro‐forestry, or even for restoration and are more likely to be introduced multiple times and disseminated widely across a landscape. Here we report on the native and alien species used for hedging purposes in rural and peri‐urban eastern Africa and undertake a preliminary assessment to ...

Abstract Windthrow is a significant disturbance in many forests globally during which strong winds damage trees or other large flora, yet its role in arid ecosystems remains largely understudied. The saguaro cactus (Carnegiea gigantea), a keystone species of the Sonoran Desert, is a long‐lived, massive succulent whose demography is primarily thought to
