MiCO: Migratory Connectivity in the Ocean

What is migratory connectivity and why is it important?

Migratory species depend on critical habitats throughout their seasonal movements, including breeding and foraging sites as well as the pathways between them. Loggerhead sea turtles, for example, can be found nesting on a beach in Japan, but forage along the Pacific coast of Mexico.

These migratory movements, as well as those of a variety of other sea turtles, marine mammals, seabirds and fish, geographically link locations and stressors in distant ecosystems. Understanding this migratory connectivity is a critical part of recognizing population trends and designing stronger conservation and management measures.
