2. Composition and seasonal variation of brachyura and anomura (Crustacea, Decapoda) associated with brown mussel farms at Praia da Cocanha, Brazil
The composition and seasonal variation of brachyuran and anomuran species associated with mussel farms were evaluated at Praia da Cocanha, São Paulo between May 2007 and February 2008. Nine mussel ropes were sampled at random in each quarter, and 1,208 organisms were identified, comprising five families and 28 species. The most numerous species was the porc

3. As comunidades macrobentÃnicas na avaliaÃÃo da qualidade ambiental de Ãreas estuarinas de Pernambuco
Estuarine environments are known by its importance in terms of complexity and biodiversity; however, anthropogenic activities continue to have a detrimental effect on its biodiversity levels on a worldwidescale. Several studies have emphasized the role of benthic macroinvertebrates as indicators of environmental quality status in these ecosystems, which have

4. Qualidade da água e distribuição espacial de foraminíferos bentônicos em estuários das Baías Norte e Sul da Ilha de Santa Catarina (Brasil)
Watersheds with different characteristics lead to different rates of biogeochemical elements that contribute in estuarine systems. Thus, this study investigated the contribution of drainage on the nutrients as well as the responses of benthic foraminifera, with focus on estuarine region of six major systems that discharge in the North and South bays of Santa

5. Caracterização física, estrutural e da diversidade floristica de fragmentos florestais na alta bacia do Rio Araguaia
The upper Araguaia river basin region has been transformed by rapid and intensive human occupation processes that began in the 1970s, and now the landscape is highly fragmented. Remnant forests are surrounded by cotton and soybean plantations and pasture. They continue to be subjected to degradation and little is known about their ecological integrity. The o

10. Estimativa de variabilidade genética em acessos crioulos e cultivares comerciais de tomates (Lycopersicon esculentum Mill.) do sul do Brasil e avaliação da presença do Gene Mi.
Cultivated tomato (Lycopersicon esculentum Mill.) is one of the most important horticultural crops. Although original from the Andes region, this crop was officially introduced in Brazil by the European immigrants during the last half of the XIX century. Today, old varieties and new improved cultivars are planted in the different Brazilian regions. In the la

11. Evolutionary emergence of size-structured food webs
Explaining the structure of terrestrial and aquatic food webs remains one of the most important challenges of ecological theory. Most existing models use emergent properties of food webs, such as diversity and connectance as parameters, to determine other food-web descriptors. Lower-level processes, in particular adaptation (whether by behavioral, developmen
