A Conceptual Framework and Methods for Studying the Connectivity of Fishes

open access: yesFish and Fisheries, Volume 27, Issue 2, Page 342-369, March 2026.
ABSTRACT Connectivity is a multifaceted concept that has important implications for the management and conservation of marine and freshwater fishes. We developed a conceptual framework that encompasses multiple, interrelated categories of connectedness, including landscape (e.g., structural, functional) connectivity and ecological (e.g., trophic ...
