Assessing sustainable lethal take for great blue heron in the northeastern United States
Wildlife Society Bulletin, Volume 50, Issue 1, March 2026.We used Prescribed Take Level (PTL) models to estimate sustainable take limits for great blue heron and aid depredation permitting decisions by the USFWS in the northeastern United States. The PTL models suggested that current lethal take levels are sustainable and that cumulative authorized regional take should not exceed 2,650 individuals per year ...

Species‐ and origin‐specific susceptibility to bird predation among juvenile salmonids
Ecosphere, 2023 Juvenile salmonids often experience high mortality rates during migration and bird predation is a common source of mortality. Research suggests that hatchery‐reared salmonids are more prone to predation than wild salmonids, and that Atlantic salmon ...

, 2021 The ecological communities we observe today are a product of the bidirectional interactions between ecological and evolutionary processes. Although the effects of ecological processes on population divergence and speciation have been studied extensively, far less is known about the effects of divergence and speciation on ecological dynamics.

A Conceptual Framework and Methods for Studying the Connectivity of Fishes
Fish 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 ...

Diets of shags Phalacrocorax aristotelis and cormorants P. carbo in Norway and possible implications for gadoid stock recruitment [PDF]
, 1990 The diets of shags and cormorants were studied in Norway through analyses of regurgitated pellets. Although this method has many limitations, indications were that both species rely heavily on small gadoids (Gadidae) and sand eels (Ammodytidae) for food ...

Ecology and Evolution, Volume 16, Issue 2, February 2026.This study evaluates fish potential production (FPP) and fish carrying capacity index (FCCI) in Qinghai Lake using satellite‐based primary production estimates. Results show increasing FPP trends and spatially heterogeneous FCCI, indicating potential for sustainable fisheries management and guiding restocking efforts in this high‐altitude lake ...
