Abstract

RODRIGUEZ, SEBASTIAN R.. Transfer of food resources among different environments in the marine ecosystem. Rev. chil. hist. nat. [online]. 2000, vol.73, n.1, pp.199-207. ISSN 0716-078X.  http://dx.doi.org/10.4067/S0716-078X2000000100017.

For decades ecologists have focused their studies in interactions among elements of the same system, putting low emphasis in those that involve elements of border environments. Studies carried out in the last years have called the attention respect the frequent ocurrence of energy transfer (as nutrients or food) among ecological systems, environments and/or habitats, and the consequences of these energy contributions at population or community levels and at different spatial and temporal scales. In this review the ways of energy transfer more commonly observed in the marine ecosystem are described. The flow of trophic resources (i.e., drift algae and detritus) from subtidal kelps to intertidal environments in template systems, are emphasized

Keywords : flow of trophic resources; subtidal-intertidal interaction; drift kelp; detritus; template systems.
