Pursuit plunging by northern gannets (Sula bassana) feeding on capelin (Mallotus villosus).
Northern gannets (Sula bassana) are considered to obtain prey usually by rapid, vertical, shallow plunge dives. In order to test this contention and investigate underwater foraging behaviour, we attached two types of data-logging systems to 11 parental northern gannets at Funk Island in the North-Wiest Atlantic. We documented, for the first time to the authors' knowledge, gannets performing lon...
متن کاملMARINE RESERVES FOR THE NORTHERN COD by
In the midst of several management failures, marine reserves are seen as a potential management tool to control overexploitation. In the literature, both modelling and empirical work have demonstrated that closing an area to fishing would lead to an increase in biomass and mean body size within the reserve. Benefits, in the form of increased catch, outside the reserves are sometimes shown using...

Signs of cod recovery
While gloom surrounds the prospects of many global fisheries, one species seems to have benefited from a range of, often controversial, conservation measures. North Sea cod, once on the brink of collapse as a result of decades of overfishing, looked set for the same fate as cod on the Grand Banks off northeast America, but new evidence suggests numbers are now recovering. In a rare positive con...
