Vertical patterns of ichthyoplankton at the interface between a temperate estua...
Primo, Ana Lígia; Azeiteiro, Ulisses M.; Marques, Sónia C.; Ré, Pedro; Pardal, M. A.Vertical distribution and migration pattern of ichthyoplankton assemblage in the Mondego estuary were investigated in relation to diel and tidal cycle. Summer and winter communities were sampled, at surface and bottom, over a diel cycle during spring and neap tides at a fixed station at the mouth of the estuary. Summer presented higher larvae density mainly of Pomatoschistus spp., Gobius niger and Parablennius ...
Impact of climate variability on ichthyoplankton communities: An example of a s...
Primo, Ana Lígia; Azeiteiro, Ulisses Miranda; Marques, Sónia Cotrim; Pardal, Miguel ÂngeloRecent variations in the precipitation regime across southern Europe have led to changes in river fluxes and salinity gradients affecting biological communities in most rivers and estuaries. A sampling programme was developed in the Mondego estuary, Portugal, from January 2003 to December 2008 at five distinct sampling stations to evaluate spatial, seasonal and inter-annual distributions of fish larvae. Gobiida...
Comunidades de blogs e espaços conversacionais
Alex Primo; Ana SmaniottoA discussão sobre comunidades virtuais aparece logo nos primeiros artigos sobre a comunicação mediada por computador. Por outro lado, o estudo sobre conversação e relações comunitárias passa apenas recentemente a atrair maior atenção das pesquisas sobre blogs, embora poucos ainda sejam os trabalhos empíricos sobre a matéria....

Predicting zooplankton response to environmental changes in a temperate estuari...
Marques, Sónia; Azeiteiro, Ulisses; Leandro, Sérgio; Queiroga, Henrique; Primo, Ana; Martinho, Filipe; Viegas, Ivan; Pardal, MiguelAbstract A novel strategy that allows to predict the responses of zooplanktonic species to environmental conditions in an estuarine temperate ecosystem (Mondego estuary) is presented. It uses 12 indicator species from the zooplanktonic Mondego database (102 species) that are common members of the different habitats, characterized by their specific hydrological conditions. Indicator-species analysis (ISA) was u...
