Density‐dependent effects on salmonid populations: A review

GD Grossman, TN Simon - Ecology of Freshwater Fish, 2020 - Wiley Online Library
We reviewed 199 published data sets (21 species) to assess the relative frequency of
various density‐dependent processes in salmonids. We examined studies for the presence …

Brook trout use of thermal refugia and foraging habitat influenced by brown trout

NP Hitt, EL Snook, DL Massie - Canadian Journal of Fisheries …, 2017 - cdnsciencepub.com
The distribution of native brook trout (Salvelinus fontinalis) in eastern North America is often
limited by temperature and introduced brown trout (Salmo trutta), the relative importance of …

Seasonal temperature and precipitation regulate brook trout young‐of‐the‐year abundance and population dynamics

Y Kanno, KC Pregler, NP Hitt, BH Letcher… - Freshwater …, 2016 - Wiley Online Library
Abundance of the young‐of‐the‐year (YOY) fish can vary greatly among years and it may be
driven by several key biological processes (ie adult spawning, egg survival and fry survival) …

The density dilemma: limitations on juvenile production in threatened salmon populations

AW Walters, T Copeland… - Ecology of Freshwater …, 2013 - Wiley Online Library
Density‐dependent processes have repeatedly been shown to have a central role in
salmonid population dynamics, but are often assumed to be negligible for populations at low …

Recovery of native brook trout populations following the eradication of nonnative rainbow trout in southern Appalachian Mountains streams

Y Kanno, MA Kulp, SE Moore - North American Journal of Fisheries …, 2016 - Taylor & Francis
Abstract Nonnative Rainbow Trout Oncorhynchus mykiss have displaced native Brook Trout
Salvelinus fontinalis in many southern Appalachian Mountains streams. We monitored the …

Density-dependent regulation of brook trout population dynamics along a core-periphery distribution gradient in a central Appalachian watershed

BM Huntsman, JT Petty - PLoS One, 2014 - journals.plos.org
Spatial population models predict strong density-dependence and relatively stable
population dynamics near the core of a species' distribution with increasing variance and …

The temperature–productivity squeeze: constraints on brook trout growth along an Appalachian river continuum

JT Petty, D Thorne, BM Huntsman, PM Mazik - Hydrobiologia, 2014 - Springer
We tested the hypothesis that brook trout growth rates are controlled by a complex
interaction of food availability, water temperature, and competitor density. We quantified trout …

Population variation in density‐dependent growth, mortality and their trade‐off in a stream fish

JM Matte, DJ Fraser, JWA Grant - Journal of Animal Ecology, 2020 - Wiley Online Library
Important variation in the shape and strength of density‐dependent growth and mortality is
observed across animal populations. Understanding this population variation is critical for …

Population regulation of brook trout (Salvelinus fontinalis) in Hunt Creek, Michigan: a 50‐year study

GD Grossman, A Nuhfer, T Zorn, G Sundin… - Freshwater …, 2012 - Wiley Online Library
Fisheries models generally are based on the concept that strong density dependence exists
in fish populations. Nonetheless, there are few examples of long‐term density dependence …

Dynamics and regulation of the southern brook trout (Salvelinusfontinalis) population in an Appalachian stream

GD Grossman, RE Ratajczak, CM Wagner… - Freshwater …, 2010 - Wiley Online Library
We used information theoretic statistics [Akaike's Information Criterion (AIC)] and regression
analysis in a multiple hypothesis testing approach to assess the processes capable of …
