Impact of predation by Cape fur seals Arctocephalus pusillus on Cape gannets Morus capensis at Malgas Island, Western Cape, South Africa
(Morus capensis) fledglings around Malgas Island in the 2000/01 breeding season, 11 000 in 2003/04 and 10 ... 000 in 2005/06. This amounted to about 29%, 83% and 57% of the overall production of fledglings at the ... island in these breeding seasons, respectively. Preliminary modelling suggests this predation is not ... sustainable. There was a 25% reduction in the size of the colony, the second largest of only six extant Cape ...

Predicting distribution and relative abundance of mid-trophic level organisms using oceanographic parameters and acoustic backscatter
Abstract: Data on the distribution and abundance of mid-trophic level organisms (MTLOs) in the ... pelagic open-ocean ecosystem are normally sparse or absent. Consequently, ecosystem models are limited in ... proxy for MTLO abundance in the epi- and mesopelagic zones. Boosted regression trees and generalised ... additive mixed models were used to develop simple predictive models for backscatter in the epi- and ...
