文摘
- •
Migratory tracks and diving behavior of 18 adult female olive ridley turtles during migration from French Guiana.
- •
Quantification of the relationships between foraging behavior and (a) oceanographic features, (b) micronekton biomass.
- •
Remote sensing data showed a productive area influenced by the Amazon River plume and characterized by anticyclonic eddies.
- •
Horizontal foraging strategies were related to high micronekton biomass and low current velocities.
- •
Vertical foraging strategies were linked to the thermocline depth.
