Numerical responses of martens to a food shortage in Northcentral Ontario
Numerical responses of martens (Martes americana) to a synchronous decline of most prey species were studied from 1980 to 1985. Main prey species included snowshoe hare (Lepus americanus), redExpand
Predator foraging success and habitat complexity: quantitative test of the threshold hypothesis
SummaryNumerous studies have demonstrated a negative relationship between increasing habitat complexity and predator foraging success. Results from many of these studies suggest a non-linearExpand

The role of learning in fish behaviour
SummaryThe behavioural patterns of fish are the result of innate (‘built-in’) patterns of maturation (developmental changes) and of learning processes (imprinting and trial-and-error learning).Expand
Comparative social recognition
Changes in the predator-avoidance behaviour of juvenile guppies (Poecilia reticulata) exposed to pentachlorophenol
The effects of pentachlorophenol on the predator-avoidance behaviour of the guppy (Poecilia reticulate) in response to largemouth bass (Micropterus salmoides) predation was investigated. There wereExpand
Size Ratios and Artifacts: Hutchinson's Rule Revisited
We show that size ratios within the range predicted by Hutchinson's rule invariably result, given only that animal sizes are distributed lognormally and that the variances of these distributions areExpand
