Plastids typically reside in plant or algal cells-with one notable exception. There is one group of multicellular animals, sea slugs in the order Sacoglossa, members of which feed on siphonaceous algae. The slugs sequester the ingested plastids in the cytosol of cells in their digestive gland, giving the animals the color of leaves. In a few species of slugs, including members of the genus Elys...

STOCK DEFINITION AND GEOGRAPHIC RANGE Steller sea lions range along the North Pacific Rim from northern Japan to California (Loughlin et al. 1984), with centers of abundance and distribution in the Gulf of Alaska and Aleutian Islands, respectively. The species is not known to migrate, but individuals disperse widely outside of the breeding season (late May-early July), thus potentially intermix...

Individual chlorinated biphenyls (CBs) and chlorinated pesticides (p,p'-DDT and metabolites, HCHs and HCB) were determined in blubber samples of 40 harbour porpoises (Phocoena phocoena) of different age and sex from the North Sea, the Baltic Sea and Greenland coastal waters. Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) were analysed in a selected group of ...

The AVMA appreciates the opportunity to provide comments on the amendments proposed during the October 2006 meeting of the Terrestrial Animal Health Standards Commission (TAHSC) to the General Definitions, Guidelines for the Transport of Animals by Sea, and Guidelines for the Transport of Animals by Land of the OIE Terrestrial Animal Health Code. As requested, our responses are formulated for e...

The recent analysis of a novel class of rare genomic changes, RGC_CAMs (after conserved amino acids-multiple substitutions), supported the Coelomata clade of animals as opposed to the Ecdysozoa clade (Rogozin et al. 2007). A subsequent reanalysis, with the sequences from the sea anemone Nematostella vectensis included in the set of outgroup species, suggested that this result was an artifact ca...

European eels (Anguilla anguilla) undertake a approximately 5000-kilometer (km) spawning migration from Europe to the Sargasso Sea. The larvae are transported back to European waters by the Gulf Stream and North Atlantic Drift. However, details of the spawning migration remain unknown because tracking eels in the Atlantic Ocean has, so far, eluded study. Recent advances in satellite tracking en...

The tunicates, sessile marine animals of the subphylum Urochorda (l), are unique in the animal kingdom in that they synthesize cellulose (2). An investigation of the pattern of carbohydrate metabolism in these animals has been undertaken as a first step in the direction of studying the biosynthesis of cellulose. The present paper deals with some of the properties of phosphoglucomutase and phosp...
