Heart rate (fH) and rate of oxygen uptake (VO2) were measured in six subadult California sea lions Zalophus californianus while they were at rest and while they were swimming for 15 min at controlled speeds of up to 1.4 m s-1 and pulling loads of up to 3 kg. There was a good linear relationship between fH and VO2 in all six sea lions. The slopes of the individual regression lines varied between...

Sulfated fucans from echinoderms (sea cucumber and sea urchin) have a linear backbone of 1-->3-linked alpha-L-fucopyranose with some sulfate substitution at the 2- and 4-positions. NMR spectroscopy indicates that both polysaccharides have a tetrasaccharide repeat unit in which the separate residues differ only in the extent and position of their sulfate substitution. The sea urchin fucan has th...

The influence of dietary protein source (fishmeal, soy-protein concentrate and soy-protein concentrate supplemented with methionine) on voluntary feed intake, daily feeding rhythm and nutritive utilisation of diet was studied in the gilthead sea bream (Sparus aurata) fed by hand or demand feeding. Fish weighing 21 g were maintained indoors under natural conditions of temperature and photoperiod...

A modularity approach is used to study disparity rates and evolvability of sea urchins belonging to the Atelostomata superorder. For this purpose, the pentameric sea urchin architecture is partitioned into modular spatial components and the interference between modules is quantified using areas and a measurement of the regularity of the spatial partitions. This information is used to account fo...

Late Pleistocene and Holocene sea-levels exhibit considerable temporal and spatial variation around the globe when compared with present-day sea-levels. This is the result of volumetric changes of the ocean produced by the melting of the Pleistocene ice sheets, the response of the crust to these redistributed surface loads, and to tectonic movements of the shore lines of other than glacio-hydro...

purpose the aim of this study was to investigat the offensive efficiency of the professional handball players forming the front and rear lines. methods our investigation was carried out on four matches (final, semi-finals and classifying match) at the 19th male handball world championship “tunisia 2005”. finalist teams were tunisia, france, croatia, and spain. matches were recorded using 5 digi...
