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

Valorization of Mexican prickly pear cladodes (Opuntia spp) as a source of antifungal compounds against phytopathogenic strains

CyTA - Journal of Food
Prickly pear cactus (Opuntia spp.) has been widely consumed in Mexico as an important source of nutrients in the diet. Older, larger, and fibrous cladodes lose commercial interest for human consumption, resulting in a by-product rich in different ...

Predictive Models for Postfire Debris Flow Initiation in the Southwest USA

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
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 ...

A Preliminary Assessment of Hedge Plant Species and Their Distribution in Rural Eastern Africa and Their Potential Role in Driving Invasions

African Journal of Ecology, Volume 64, Issue 4, June 2026.
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 ...

Potential of the Predatory Mites Gamasellodes lavafesii (Mesostigmata: Ascidae) and Cosmolaelaps mediocuspis (Mesostigmata: Laelapidae) on Different Soil Pests/Parasites and Alternative Prey for Large‐Scale Rearing

Journal of Applied Entomology, Volume 150, Issue 5, Page 562-572, June 2026.
ABSTRACT Many species of Mesostigmata soil mites have potential as biological control agents of pests/parasites. This study evaluated the predation potential of two of these species, Gamasellodes lavafesii (Ascidae) and Cosmolaelaps mediocuspis (Laelapidae).

Mass mortality of saguaros (Carnegiea gigantea) from windthrow: A rare, demographic disturbance in a desert ecosystem

Ecosphere, Volume 17, Issue 5, May 2026.
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

Biological and environmental drivers of early life fawn survival in a declining pronghorn population

Wildlife Biology, Volume 2026, Issue 3, May 2026.
Pronghorn Antilocapra americana occupy only a portion of their historical range and in Oklahoma occur at the eastern edge of the species' contemporary distribution. Monitoring has suggested pronghorn populations in Oklahoma have declined in recent years.
