Geographer presents new risk model that offers a more nuanced view of complex crises
Stages of the multiple stressor framework. Credit: One Earth (2024). DOI: 10.1016/j.oneear.2024.09.006 We live in a time of multiple crises: climate disasters, pandemics, species extinctions, and violent conflicts. Researchers and policymakers around the world are searching for ways to appropriately respond to this multi-headed monster. Easier said than done. “Systemic risks are increasingly concentrated in the Anthropocene, the era of…

Octopuses cooperate with fish to hunt, but the way they share decisions is surprisingly complex
Credit: Pixabay/CC0 Public Domain A new study published in Nature Ecology & Evolution sheds light on what happens when octopuses and fish hunt together. As it turns out, this cross-species relationship is more complicated than anyone expected. Animals of the same species often cooperate and work together to achieve some goal. However, cooperation between individuals of different species is relatively…
