Biodiversity and ecosystems are foundational to the Sustainable Development Goals (SDGs). They are explicitly recognized in SDG 14 (Life Below Water) and SDG 15 (Life on Land), which aim to conserve and sustainably use aquatic and terrestrial ecosystems. Biodiversity and healthy ecosystems also support SDG 2 (Zero Hunger) by providing the variety of life that underpins agricultural productivity. They contribute to SDG 6 (Clean Water and Sanitation) by providing essential water filtration services, and to SDG 3 (Good Health and Well-being) by regulating disease and offering potential sources for medical discoveries. Moreover, these biological resources play a significant role in climate change mitigation and adaptation, linking to SDG 13 (Climate Action). Hence, the protection of biodiversity and ecosystems is essential to achieving multiple SDGs.
Facultative polyandry protects females from compromised male fertility caused by heatwave conditions
Animal Behaviour, Volume 178, August 2021
Why is polyandry such a common mating behaviour when it exposes females to a range of significant fitness costs? Here, we investigated whether polyandry protects females against reduced male fertility caused by thermal stress from heatwave conditions. Sperm production and function are vulnerable to heat, and heatwave conditions are forecast to increase as our climate warms, so we examined these effects on female reproduction and mating behaviour in the flour beetle, Tribolium castaneum, a promiscuous ectotherm model in which fertility is damaged by environmental warming.
