Testing Relationships between Energy and Vertebrate Abundance
Understanding what drives variation in the abundance of organisms is fundamental to evolutionary ecology and wildlife management. Yet despite its importance, there is still great uncertainty about the main factors influencing variation in vertebrate abundance across taxa. We believe valuable knowled...

Understanding what drives variation in the abundance of organisms is fundamental to evolutionary ecology and wildlife management.
