organisms, (5) the role of feeding behaviour in food web dynamics and trophic controls, (6) the spatial dynamics of communities and links between different food webs, (7) the combined effects of body size and behaviour in determining dynamics of food webs, and (8) the extent to which the...
The food web incorporates the decomposers, which are essential in breaking down dead remains of living organisms into nutrients utilized by producers. Also, a food web is applied to examine how matter and energy flow within the trophic levels....
this study was to determine (i) the importance of riverine and marine organic matter for the Thukela Bank food web; and (ii) whether there are seasonal changes in the Thukela River stable isotope values, and, if so, whether these are reflected in the isotope values of demersal organisms....
“These calcifying organisms will struggle to build and maintain their shells as acidification proceeds,” saidNicole Lovenduski, of the University of Colorado at Boulder, one of the researchers. Inevitable result “In the future, a pocket of corrosive water will sit just below the surface, makin...
Foodweb: A succession of organisms in an ecosystem that is linked by predator–prey relationships, transferring mass and energy from one to another. Global fallout: Residual radiation hazard from the atmospheric nuclear explosions of the 1940s to 1960s, with slowly declining global presence in the...
Detection of plastic debris degrading into micro particles across all oceanic environments and inside of marine organisms is no longer surprising news. Microplastic contamination now appears as one of the world’s environmental main concerns. To determine the levels of microplastic pollution at sea, wat...
We show that decaying jellyfish blooms are associated with the enrichment in extracellular collagenolytic bacterial proteases, which could act as virulence factors in human and marine organisms’ disease, with possible implications for marine ecosystem services. Our study also provides novel insights ...
up the food web may further support previous results that higher trophic levels may be less sensitive to climatic stressors than lower trophic levels. There is a growing interest in how climate change impacts on marine organisms change along latitudinal gradients3,73. It is, for example, widely...
In these environments, small organisms can become concentrated, providing a rich supply of food for other animals. Marine biota Marine biota can be classified broadly into those organisms living in either the pelagic environment (plankton and nekton) or the benthic environment (benthos). Some ...
Copepods and krill are important components of most marine food webs. Planktonic (i.e., drifting) copepods, such as Calanus, and members of the order Euphausiacea (euphausiids), or krill, may be present in such great numbers that they discolour large areas of the open sea, thus indicating...
