New global area estimates for coral reefs from high-resolution mapping Open
Summary: Coral reefs underpin the environmental, social, and economic fabrics of much of the world's tropical coast. Yet, the fine-scale distribution and composition of coral reefs have never been reported consistently across the planet. H…

High resolution lidar data shed light on inter‐island translocation of endangered bird species in the Hawaiian Islands Open
Translocation, often a management solution reserved for at‐risk species, is a highly time‐sensitive intervention in the face of a rapidly changing climate. The definition of abiotic and biotic habitat requirements is essential to the selec…
