The productivity and linkages in the food web of the southern region of the west Antarctic Peninsula continental shelf were investigated using a multi-trophic level mass balance model. Data collected during the Southern ...

In lake food webs, pelagic basal organisms such as bacteria and phytoplankton incorporate mercury (Hg2+) from the dissolved phase and pass the adsorbed and internalized Hg to higher trophic levels. This experimental inve...

In this paper we review several studies on V. germanica behavioral plasticity while relocating a food source in natural environments. This exotic social wasp, which has become established in many parts of the world, disp...

The incorporation and trophic transfer of total and methyl mercury (THg, MeHg) were examined in three size classes of plankton (10–53, 53–200, and >200 μm size range) and a small planktivorous fish, Galaxias maculat...

Drepanopus forcipatus and Calanus australis are key planktonic copepods on the southern Patagonian shelf. Their feeding and reproductive patterns and population status were investigated during late summer, when environme...

Bacillus cereus is an endospore-forming, Gram-positive bacterium able to cause food-borne diseases. Lactic acid bacteria are known for their ability to synthesize organic acids and bacteriocins, but the potential of thes...
