Specific niche characteristics facilitate the invasion of an alien fish invader in boreal streams [PDF]

open access: yes, 2012
We studied the ecological niche relations of native stream fish and an alien invader, brook trout (Salvelinus fontinalis), to examine if brook trout had located an underused environmental niche in our boreal study system. In both study years (1994 versus

A Conceptual Framework and Methods for Studying the Connectivity of Fishes

open access: yesFish and Fisheries, EarlyView.
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 ...
