Spatial interaction between seabirds and prey: review and synthesis
The Ideal Free Distribution theory predicts a close spatial match between predators and prey. Studies have shown that seabird and prey distribution seldom conforms with this prediction. In this study, I review recent theoretical advances in spatial predator–prey interactions and relate these with studies of seabirds and pelagic schooling fish and crustaceans. Studies on seabirds and prey have g...
متن کاملon the relationship between linguistic, visual-spatial, interpersonal intelligences and technical translation quality
abstract this study tried to investigate whether there was any significant relationship between technical translation quality of the senior english translation students and their levels of verbal-linguistic, visual-spatial and interpersonal intelligences. in order to investigate the research questions, the researcher selected a hundred senior english translation students from three universitie...
Spatial aggregations of seabirds and their prey on the continental shelf off SW Vancouver Island
We investigated the spatial scales at which seabirds aggregate and associate with prey over the continental shelf off southwest Vancouver Island, British Columbia. Bird densities and hydroacoustic measures of prey abundance were recorded in all seasons from 1993 to 1995 from a vessel moving along fixed strip transects (mean distance 93 km; minimum spatial units 250 m). We used the neighbour K a...
متن کاملThe interaction between predation and competition: a review and synthesis
Jonathan M. Chase*, Peter A. Abrams, James P. Grover, Sebastian Diehl, Peter Chesson, Robert D. Holt, Shane A. Richards, Roger M. Nisbet and Ted J. Case *Correspondence: E-mail: [email protected] Abstract This review discusses the interface between two of the most important types of interactions between species, interspecific competition and predation. Predation has been claimed to increase, decr...
