Lipid corrections in carbon and nitrogen stable isotope analyses: comparison of chemical extraction and modelling methods
John M. Logan,Timothy D. Jardine,Timothy J. Miller,Stuart E. Bunn,Richard A. Cunjak,Molly Lutcavage +5 more
TL;DR: This work compared chemical extraction and mathematical correction methods for freshwater and marine fishes and aquatic invertebrates to better understand impacts of correction approaches on carbon (delta(13)C) and nitrogen (d delta(15)N) stable isotope data.
Journal ArticleDOI
Winter habitat of selected stream fishes and potential impacts from land-use activity
TL;DR: The habitat characteristics and the behaviour of selected stream fishes during winter in temperate-boreal ecosystems are reviewed and maintenance of habitat complexity, at least at the scale of stream sub-basin, is recommended to ensure the diversity of winter habitats for fish communities.
Journal ArticleDOI
Winter Habitat Utilization by Stream Resident Brook Trout (Salvelinus fontinalis) and Brown Trout (Salmo trutta)
Richard A. Cunjak,Geoffrey Power +1 more
TL;DR: Habitat utilization by brook trout and brown trout is described from three winters of underwater observations in a southern Ontario river; older trout (>age 1) generally occupied positions in deeper and faster water than age 0+ trout.
Journal ArticleDOI
Spatial niche variability for young Atlantic salmon (Salmo salar) and brown trout (S. trutta) in heterogeneous streams
TL;DR: Stream habitat selection studies are reviewed and results to variable and interacting abiotic and biotic factors are related, showing flexibility with respect to preferred water velocity, depending on fish size, intra- and interspecific competition, and predation risk.
Journal ArticleDOI
Atlantic salmon (Salmo salar) in winter: "the season of parr discontent"?
TL;DR: This paper synthesizes recent advances in the biological and hydrologic/ geomorphic disciplines, with specific reference to Atlantic salmon overwintering in the freshwater portions of those running waters subject to freezing water temperatures, to explain interannual variability in juvenile abundance.
