1. Reguladores da dinâmica das comunidades planctônicas e íctica em ecossistemas límnicos subtropicais
As comunidades mudam no tempo e espaço em função de pressões decorrentes da estrutura do habitat e disponibilidade de recursos. O entendimento das relações ecológicas e interações das comunidades são essenciais para o manejo com objetivo de melhorar a qualidade da água através de interferências na cadeia trófica aquática e na dinâmica do ecos

2. DinÃmica do microzooplÃncton no Canal de Santa Cruz, Pernambuco, Brasil
Studies were carried out to assess the transport dynamics and the microzooplanktonic community structure from the south and north inlets of Santa Cruz Channel (Itamaracà â PE) in relation to the adjacent shelf, considering tidal phases and depth. Plankton samples were taken with a pump at three stations along a transect across the inlets. At the central st

3. Contribution to limnological knowledge of brazilian semi-arid reservoir that supply Fortalezas metropolitan region: Pacajus and Gavião dams (Ceará, Brazil) / Contribuição ao conhecimento limnológico de reservatórios do semi-árido brasileiro que abastecem a região metropolitana de Fortaleza: Açudes Pacajus e Gavião (Ceará, Brasil)
The main aim of this research was to investigate the influence of climatic and hydrodynamicsalterations about physical stability, resources availability, zooplankton community structure and spatial heterogeneity standard of Pacajus and Gavião dams, collected at two-month period between Nov. 1988 and Dec. 1998. In the reservoirs, the sample stations were dis

4. VariaÃÃo espacial e temporal da comunidade microfitoplÃnctÃnica em ecossistemas costeiros localizados no litoral sul de Pernambuco, Nordeste do Brasil
The coastal marine environment shows a strong ocean- continent-atmosphere interaction and for that reason is considered extremely complex from the biological point of view due to the influence of many systems, so it can be characterized as one of the most fertile and dynamic of the hydrosphere. The estuarine complex (Ilhetas and Mamucaba rivers) and the Tama

5. Rapid contemporary evolution and clonal food web dynamics
Character evolution that affects ecological community interactions often occurs contemporaneously with temporal changes in population size, potentially altering the very nature of those dynamics. Such eco-evolutionary processes may be most readily explored in systems with short generations and simple genetics. Asexual and cyclically parthenogenetic organisms

6. Virioplankton: Viruses in Aquatic Ecosystems†
The discovery that viruses may be the most abundant organisms in natural waters, surpassing the number of bacteria by an order of magnitude, has inspired a resurgence of interest in viruses in the aquatic environment. Surprisingly little was known of the interaction of viruses and their hosts in nature. In the decade since the reports of extraordinarily larg

7. Molecular evidence links cryptic diversification in polar planktonic protists to Quaternary climate dynamics
It is unknown how pelagic marine protists undergo diversification and speciation. Superficially, the open ocean appears homogeneous, with few clear barriers to gene flow, allowing extensive, even global, dispersal. Yet, despite the apparent lack of opportunity for genetic isolation, diversity is prevalent within marine taxa. A lack of candidate isolating mec
