A quantitative assessment of fish passage efficiency
In an attempt to restore the connectivity of fragmented river habitats, a variety of passage facilities have been installed at river barriers. Despite the cost of building these structures, there hasExpand
Territory Size as a Predictor of the Upper Limit to Population Density of Juvenile Salmonids in Streams
We examined the old, but untested hypothesis that territory size limits the maximum population density of salmonids in streams. We used published data to derive an interspecific regression of terri...
Density-dependent growth of young-of-the-year Atlantic salmon Salmo salar in Catamaran Brook, New Brunswick
Summary 1 While density-dependent mortality and emigration have been widely reported in stream salmonid populations, density-dependent growth is less frequently detected. A recent studyExpand
Do in-stream restoration structures enhance salmonid abundance? A meta-analysis
Despite the widespread use of stream restoration structures to improve fish habitat, few quantitative studies have evaluated their effectiveness. This study uses a meta-analysis approach to test theExpand
The Influence of Operational Sex Ratio on the Intensity of Competition for Mates
The evolution and maintenance of secondary sexual characteristics and behavior are heavily influenced by the variance in mating success among individuals in a population. The operational sex ratioExpand
Threats to Endangered Species in Canada
ABSTRACT We quantified the threats facing 488 species in Canada, categorized by COSEWIC (Committee on the Status of Endangered Wildlife in Canada) as extinct, extirpated, endangered, threatened, orExpand
Operational sex ratio, mediated by synchrony of female arrival, alters the variance of male mating success in Japanese medaka
Abstract The hypotheses that variation in male mating success and use of aggression by competing males increase with decreasing synchrony of female arrival were experimentally tested. Groups of threeExpand
Patterns of density-dependent growth in juvenile stream-dwelling salmonids
Literature data for 19 populations from 16 different studies of six species of stream-dwelling salmonids were analysed to test the hypothesis that density-dependent growth is stronger at low ratherExpand
The effect of visual isolation on territory size and population density of juvenile rainbow trout (Oncorhynchus mykiss)
Visibility is thought to affect the territory size of visually oriented animals but there have been few experimental tests of the hypothesis. We re-examined the relationship between visibility andExpand
