1. Shredders prefer soft and fungal-conditioned leaves, regardless of their initial chemical traits
RESUMO Nós investigamos em experimento de campo e de laboratório os efeitos das características foliares e condicionamento microbiano de duas espécies de árvores na abundância, biomassa e preferência alimentar de um fragmentador típico. No experimento de campo, comparamos a associação do Phylloicus (Calamoceratidae, Trichoptera) entre duas espécie

2. Effects of anthropogenic impacts on benthic macroinvertebrates assemblages in subtropical mountain streams
The nature of the riparian and surrounding landscape has been modified by anthropogenic activities, which may subsequently alter the composition and functional structure of macroinvertebrate assemblages. The effect of these changes on function of benthic fauna is difficult to assess due to the scarce knowledge on functional structures in tropical streams. In

3. Experimental assessment of temperature increase and presence of predator carcass changing the response of invertebrate shredders
O papel dos invertebrados fragmentadores no processo de decomposição foliar em ecossistemas lóticos tropicais vem sendo recentemente explorado. Além da influência da qualidade do detrito e da temperatura, o risco de predação geralmente implica alterações sobre a sobrevivência e comportamento de invertebrados fragmentadores. O objetivo deste estudo

4. Análise do processo de gestão de custos dos agentes que compõem a cadeia produtiva da cultura do sisal no estado da Paraíba
The Brazil is globally the most producer of sisal, and it is produced exclusively in the Northeast Region, especially in States of Bahia and of Paraíba, places where respond for job and income generation, mainly in poor locations, making to increase its relevance in the socioeconomic context. So the present study had as objective to analyze the adaptations

5. Neutral Theory could explain diversity of aquatic insects in streams? / A Teoria Neutra pode explicar a diversidade de insetos aquáticos em riachos?
The generality of Unified Neutral Theory of Biodiversity and Biogeography was evaluated across its support for diversity structure of Odonata adults and predators, shredders and collectors insect guilds in streams. The evaluation of Neutral Theory was done in two levels of theorys hierarchical structure. One evaluation in the level of yours assumptions, the

6. Dinâmica de macroinvertebrados em um lago costeiro do sul do Brasil(Lagoa da Reserva, Mostardas-RS)
In view of its great biological diversity and productivity, in addition to its many functions and values, the wetlands ecosystems are priority for conservation. The lack of information about biodiversity is the main limitation for their conservation. Moreover, the identification of the environmental factors responsible for the structure of biological communi

7. Insectos acuáticos asociados a los lagos interdunarios de la región central del Estado de Veracruz, México
The aim of this study is to register the presence of aquatic insects during the rainy and dry seasons, in 15 dune lakes of the Gulf of Mexico's coastal zone. These ecosystems lodge a wealth of 62 families, 60 of them present during the rainy season and 46 during the dry period. At both times Coleoptera is the order with a greater number of families, followed

8. Efeitos dos macroconsumidores (peixes e camarões) sobre a assembléia de insetos aquáticos e na taxa de degradação de folhas em riachos de floresta de terra firme, Amazônia central
Este trabalho teve como objetivo verificar os potenciais efeitos sobre a assembléia de insetos aquáticos e degradação de folhas causados pela exclusão de macroconsumidores (peixes e camarões). A diminuição na taxa de degradação e o aumento na abundância de alguns táxons eram esperadas na ausência de macroconsumidores, como observado em outros es

9. Comparison of Degradative Ability, Enzymatic Activity, and Palatability of Aquatic Hyphomycetes Grown on Leaf Litter
Stream fungi have the capacity to degrade leaf litter and, through their activities, to transform it into a more palatable food source for invertebrate detritivores. The objectives of the present study were to characterize various aspects of fungal modification of the leaf substrate and to examine the effects these changes have on leaf palatability to detrit
