Description
Fereshteh Khaleghdadi and colleagues studied in 2026 how climate shapes breeding timing in urial wild sheep across six protected areas in Iran. These mountain sheep breed in tight seasonal windows matched to forage growth. Weather records from the nearest stations supplied temperature, rain, snow, and humidity for each site. Statistical models weighed climate and geography against observed mating and lambing dates over the past decade.
Mating time shifted clearly with latitude, summer heat, and autumn rainfall in the models. Higher latitude and more autumn rain delayed mating, while warmer summers advanced it. Lambing time depended mostly on which study area the sheep lived in, rather than on single weather measures. Local site differences therefore dominate birth timing in this species, the authors conclude. They urge wildlife managers to build breeding-season shifts into climate adaptation plans for arid mountain habitats.
