Efeitos de peixes zooplanctívoros e onívoros sobre a resposta de comunidades planctônicas à fertilização por nutrientes
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em EcologiaBioecologia Aquática, 2009-05-29)
The food chain theory predict that presence of omnivory prevent the trophic cascade and could be a strong stabilizing factor over resource and consumer community dynamics, and that the nutrient enrichment destabilize ...
Temporal variability of the macroinvertebrate community associated with Eichhornia azurea (Swarts) Kunth (Pontederiaceae) in a lake marginal to a tropical river
(2018-01-01)
Aquatic macroinvertebrates have a close relationship with associated floating macrophytes, especially with the roots. The plant root mass is an environment favorable to the development of the macroinvertebrate fauna, ...
Temporal asynchrony in fine-root biomass may contribute to shrub and grass coexistence in mixed patches
(Wiley, 2014-01-15)
We described seasonal changes in fine-root biomass of a grass and a shrub dominant species in a plant community characteristic of the arid Patagonian Monte and then we inferred to want extent the observed differences could ...
Temporal variability of chlorophyll-a in the São Vicente estuary
(Universidade de São Paulo, Instituto Oceanográfico, 2012)
Estuaries are extremely dynamic environments that are vulnerable to anthropogenic alterations. Thus, monitoring phytoplankton abundances and composition is an essential tool for the prediction of eutrophication and its ...

Larvacean (Chordata, Tunicata) abundance and inferred secondary production off southeastern Brazil
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2011)
We studied the temporal and vertical variability in larvacean abundance and secondary production on a fixed station off southeast Brazil, from January 2007 to December 2008. Larvacean biomass was derived from length weight ...
