Qing Cao: Coexistence between Przewalski’s horse and Asiatic wild ass in the desert

Shortlisted for the 2025 Southwood Prize About the research Overview Our paper explores how two closely related wild equids—Przewalski’s horses and Asiatic wild asses—coexist in the extremely water-limited deserts of the Dzungarian Gobi. Classical niche theory would predict competitive exclusion under such scarcity, especially since horses are more water-dependent. By combining controlled water-use experiments with long-term camera trap data, we asked: what defines their fundamental water … Continue reading Qing Cao: Coexistence between Przewalski’s horse and Asiatic wild ass in the desert

Wide-scale rangeland condition monitoring: Measurement of increased vegetation cover following stock removal and conservation management

Angus Retallack explains how, using remote sensing data over a 22-year observation period, vegetation recovery after the removal of livestock and the introduction of conservation-focused management can be assessed. Arid and semi-arid rangelands cover close to 50% of the Earth’s land surface and are relied upon by a diverse range of stakeholders including Indigenous people, pastoralists and environmental conservationists. Sustainable use and conservation of these … Continue reading Wide-scale rangeland condition monitoring: Measurement of increased vegetation cover following stock removal and conservation management
