A Comparison of von Bertalanffy and Polynomial Functions in Modelling Fish Growth Data
We compared the von Bertalanffy growth function (VBGF) and five polynomial functions (PF) in modelling fish growth for 16 populations comprising six species of freshwater fishes. Ranked results ofExpand

Acidification of the La Cloche Mountain Lakes, Ontario, and Resulting Fish Mortalities
The loss of populations of lake trout (Salvelinus namaycush), lake herring (Coregonus artedii), white suckers (Catostomus commersoni), and other fishes in Lumsden Lake was attributed to increasingExpand

Similarity Coefficients: Measures of Co-Occurrence and Association or Simply Measures of Occurrence?
Data on the presence or absence of 25 fish species in a survey of 52 lakes from the watersheds of the Black and Hollow rivers of south-central Ontario were analyzed with eight similarityExpand

Biogeographic Associations in Fish Assemblages: Local vs. Regional Processes
Six geographic regions along the Laurentian Great Lakes in Ontario, represented by 286 lakes, were examined to identify the existence of regional similarities of fish species composition and theirExpand

Fish and Benthic Invertebrates: Community Concordance and Community–Environment Relationships
Fish and benthic invertebrates from 40 lakes in south-central Ontario showed significantly concordant patterns based on community structure. Fish communities were associated significantly with lakeExpand

Qualitative and quantitative sampling of lake fish communities
We demonstrated that estimates of the relative abundance and patterns of covariation for fish species captured in baited minnow traps, plastic traps, fine- and coarse-mesh trap nets, and multimeshExpand

The relative importance of manganese and iron oxides and organic matter in the sorption of trace metals by surficial lake sediments
The sorption of trace metals (Zn, Ni, and Cu) by surficial sediments of four acid (pH < 5.6) and three circumneutral (pH 6.4–6.5) lakes were compared via distribution coefficients (KD). These wereExpand

Sublethal copper toxicity and food response in the freshwater crayfish Cambarus bartonii (Cambaridae, Decapoda, Crustacea).
Food response preceding and following exposure to Cu concentrations of 0.00, 0.02, and 0.2 mg/L was observed in male and female Cambarus bartonii from an uncontaminated, freshwater lake. The animalsExpand

Influence of Predatory Fish Density on Trapability of Crayfish in Ontario Lakes
In 19 central Ontario lakes the catches of crayfish in baited minnow traps usually were well predicted by numbers of crayfish counted in timed underwater searches. Exceptions were lakes withExpand
