Long‐term surveillance reveals hybridization by nuclear reassortment and intercontinental spread as major evolutionary drivers in wheat yellow rust

New Phytologist, Volume 251, Issue 4, Page 2091-2106, August 2026.
Documented incursions of Puccinia striiformis 2009–2023 based on sequential resampling of MLGs/pathogen races on different continents. Summary Evolutionary forces affecting crop pathogens, including hybridization and long‐distance dispersal (LDD), may have strong implications for food security and sustainable plant disease control at global scales ...

Contrasting Refugial Dynamics in Central Apennine Sky‐Islands: A Comparative Phylogeography of Two Endemic Beetles

Journal of Biogeography, Volume 53, Issue 6, June 2026.
ABSTRACT Aim Quaternary climatic oscillations have profoundly shaped the genetic structure and geographic distributions of alpine biotas. Understanding how cold‐adapted taxa responded to past climatic shifts is essential for unravelling the processes shaping mountain biodiversity, yet cold‐adapted taxa may have followed divergent refugial histories. We

The pollination ecology and mouthpart morphology of a pollen‐feeding fly Incurviseta cf. maculifrons (Diptera: Lauxaniidae) in the Australian Alpine

Physiological Entomology, Volume 51, Issue 2, Page 214-225, June 2026.
The Lauxaniid fly Incurviseta cf. maculifrons (Malloch, 1925) is a locally abundant but poorly understood flower visitor in the Australian Alpine. We describe the flower visitation, pollen transport, pollen diet and mouthpart morphology of I. cf. maculifrons using field observations, pollen analyses and scanning electron microscopy. I. cf.

Pollinator conservation paradox: Exotic wildflowers provision native pollinators under anthropogenic changes

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Invasive wildflowers pose a conservation paradox: While they often reduce the diversity and abundance of native wildflowers, they can provide resources for native pollinators, including imperiled species. Previous work has framed wildflower invasions as outcomes of global change, but less is known about how interacting anthropogenic drivers ...

Alternative Approaches and Plant‐Based Remedies for Livestock Health Management Among the Batswana of Southern Africa: A Review

Chemistry &Biodiversity, Volume 23, Issue 4, April 2026.
ABSTRACT Due to limited access to, and the high cost of conventional veterinary services, Batswana communities often rely on ethnoveterinary practices for livestock health management. This review provides an in‐depth analysis on the ethnoveterinary uses, biological properties and safety assessment of plants utilised in livestock husbandry. A systematic
