Prey Exchange Rates and the Impact of Predators on Prey Populations in Streams
We present four lines of evidence that the magnitude of prey exchange (=immigration/emigration) among substrate patches has an overwhelming influence on the perceived effects of predators on prey populations. (1) An extensive ...
Tidal and turbidity effects on the shallow-water fish assemblage of Kuwait Bay
Effects of location, diel period, tidal condition and water clarity on the size and distribution of the shallow water fish assemblage of the non-estuarine Kuwait Bay, were investigated using a beach seine and a small ...

Effect of Boundary Layers on Cutaneous Gas Exchange
Boundary layers may offer significant resistance to cutaneous oxygen uptake by amphibians in water. This hypothesis was tested by measuring resistance to oxygen uptake as a function of water velocity in bullfrogs submerged ...
Community Dynamics on a Subtidal Cobble Bed Following Mass Mortalities of Sea Urchins
The macrobenthic community of a shallow subtidal cobble bed at Eagle Head on the Atlantic coast of Nova Scotia [Canada] was monitored from ca 4 mo before to 41 mo after mass mortalities of sea urchins Strongylocentrotus ...
