Ecology and Evolution, Volume 16, Issue 2, February 2026.Our study investigates the environmental and astronomical drivers of olive ridley (Lepidochelys olivacea) hatching success at Batu Hiu Beach, Indonesia. We demonstrate that air temperature is the dominant predictor of hatching outcomes, while Earth–Moon distance exerts an additional, significant influence independent of humidity and tidal effects ...

Disentangling the potential of protected areas to promote sustainable development
Frontiers in Ecology and the Environment, Volume 24, Issue 1, February 2026.Protected areas (PAs) and other effective area‐based conservation measures (OECMs) are crucial to sustainable development, yet their contributions to environmental, social, and economic dimensions remain unclear. We investigated the role of PAs and OECMs in advancing the sustainable development agenda by summarizing 400 effect‐size values and measuring
