Male‐Biased Adult Mortality in the Great Bustard Is Consistent With High Reproductive Costs and Aggravated by Anthropogenic Impact

Ecology and Evolution, Volume 16, Issue 1, January 2026.
Annual survival of great bustards (Otis tarda) was lower in males than in females, with minimum values just after the mating and incubation period, respectively, a pattern that is consistent with the reproductive cost hypothesis. Survival was lower in Madrid, a highly anthropized region (males: 0.874, females: 0.931), than in Villafáfila, where good ...

Natural variation of response to glyphosate in Sinapis alba (Brassicaceae): Physiological effects, shikimate accumulation and genetic mechanisms

Weed Research, Volume 65, Issue 5, September/October 2025.
Abstract Glyphosate is the most widely used herbicide worldwide, and glyphosate‐resistant weeds have increased globally. Resistance mechanisms, including target‐site resistance (TSR) and non‐target‐site resistance (NTSR), are well documented, but their extent and importance are poorly understood among biotypes. This study examines the natural variation

Effectiveness of protected areas in the Caucasus Mountains in preventing rangeland degradation

Conservation Biology, Volume 39, Issue 3, June 2025.
Abstract As land use intensifies globally, it increasingly exerts pressure on protected areas. Despite open, nonforested landscapes comprising up to 40% of protected areas globally, assessments have predominately focused on forests, overlooking the major pressures on rangelands from livestock overgrazing and land conversion.
