Simulated overfishing and natural eutrophication promote the relative success of a non-indigenous ascidian in coral reefs at the Pacific coast of Costa Rica
(2017)
Colonial ascidians of the genus Didemnum are common fouling organisms and are typically associated with degraded ecosystems
and anthropogenic structures installed in the sea. In this study, however, the non-indigenous ...

Evaluation of the aquatic macroinvertebrate community as a tool for monitoring a reservoir in the Pitangui river basin, Parana, Brazil
(FUNDACAO ZOOBOTANICA RIO GRANDE SUL, MUSEU CIENCIAS NATURAIS, 2011)
Evaluation of the aquatic macroinvertebrate community as a tool for monitoring a reservoir in the Pitangui river basin, Parana, Brazil. Benthic and nektonic macroinvertebrates play an important role in the structure and ...
Ciliates from eutrophized water in the northern Brazil and morphology of Cristigera hammeri Wilbert, 1986 (Ciliophora, Scuticociliatia)
(Elsevier Gmbh, 2014-02-04)
Ciliates occur in all major aquatic and soil environments worldwide and are important links in the microbial food webs, which,along with other free-living protists, are generally overlooked in biodiversity conservation ...
Águas acumuladas em açudes e barragens na região de Santa Maria e flutuações em seus atributos físico químicos
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Ciência do Solo, 2005-09-30)
The quality of superficial waters of reservoirs depends on the form of ground
use occupation on the catchments area. As the recharge is superficial emanation the
enrichment of the water with plants nutrients is consequence ...
Veligers of the invasive bivalve Limnoperna fortunei in the diet of indigenous fish larvae in a eutrophic subtropical reservoir
(Wiley Blackwell Publishing, Inc, 2017-11)
Larval fish development depends largely on their ability to capture and ingest food items, and on food availability. In this context, invasive species, eutrophication and river impoundments have complex impacts on fish ...
Avaliação da qualidade da água e influência do uso e ocupação do solo em microbacias do Lajeado Três Passos no noroeste do Rio Grande do Sul
(Universidade Federal de Santa MariaBrasilUFSMUFSM Frederico Westphalen, 2023-01-24)
The water quality of watercourses is impacted by anthropic activities, mainly due to the development of urban areas and agriculture. Thus, the present study aimed to evaluate the water quality and the influence of land use ...
