Predator size - prey size relationships of marine fish predators: interspecific variation and effects of ontogeny and body size on trophic-niche breadth
Examination of predator size - prey size relationships for 18 species of marine fish predators from continental shelf waters off the northeast US coast demonstrated that the range of prey sizes eaten expanded with increasing predator body size for each of the marine predators examined, leading to asymmetric predator size- prey size distribu- tions.

The ecological consequences of limb damage and loss in decapod crustaceans: A review and prospectus
An overview of the incidence of limb damage and loss in decapod crustaceans; review the literature on the ecological consequences of such injury; and suggest areas for future research are suggested. Expand
Scatter diagrams have historically proved useful in the study of associative relationships in ecology. Several important ecological questions involve correlations be- tween variables resulting inExpand
Comparing Early Life History Strategies of Pomatomus saltatrix: a Global Approach
This paper summarizes available life history information from the different regions where P. saltatrix occurs, with a focus on the early life history, to identify areas where more research is needed to assess the degree to which populations of a global species are adapted to their local environment.

The importance of statistical power analysis: an example from Animal Behaviour
Statistical significance and biological significance are not the same thing. For example, given a large enough sample size, any statistical hypothesis test is likely to be statistically significant,Expand
Infectious disease, shifting climates, and opportunistic predators: cumulative factors potentially impacting wild salmon declines
An overview of the evolutionary and ecological impacts of infectious diseases in wild salmon is provided and ways in which modern technologies can elucidate the microparasites of greatest potential import are suggested. Expand
Predation by juvenile piscivorous bluefish (Pomatomus saltatrix): the influence of prey to predator size ratio and prey type on predator capture success and prey profitability
Capture success, handling time, prey vulnerability, and prey profitability were examined as a function of prey length/predator length ratio for age-0 juvenile bluefish feeding on juvenile striped bass and Atlantic silverside. Expand
Nocturnal activity of juvenile Atlantic salmon (Salmo salar) in late summer: evidence of diel activity partitioning
Nocturnal activity in late summer may enable salmon to maintain population densities when space and suitable feeding areas may be limited and should be considered in studies of habitat use, competition, time budgets, and associated bioenergetic processes. Expand
Feeding ecology and niche segregation in oceanic top predators off eastern Australia
Differences in prey type and size, feeding times and depths were noted across the range of species examined to the extent that predators with overlapping prey fed at different times of the diel period or at different depths. Expand
Why do decapod crustaceans prefer small-sized molluscan prey?
If predation costs are assumed to be non-renewable, then the probability of exhausting them can be included as an additional parameter in the classical diet breadth model and the importance of predation cost selection can be extended to other predators that use mechanical means to attack their prey.
