1. Estrutura e interações tróficas em três lagoas marginais no Pantanal Sul / Structure and trophic interactions in three lagoons in the southern Pantanal
Neste trabalho, as interações tróficas e os fluxos de energia/matéria de três lagoas marginais do Pantanal (MS) submetidas ao pulso de inundação anual - Baía da Onça, Braço Morto Acima e Braço Morto Abaixo - foram analisados com modelos de balanço de massas elaborados no software Ecopath. Assim, os objetivos foram: (i) descrever os mecanismos que

3. Isotopical analysis of the diet and subsistence patterns of pre-historical huntergatherer groups from Central Brazil / Reconstituição da dieta e dos padrões de subsistência das populações pré-históricas de caçadores-coletores do Brasil Central através da ecologia isotópica
Research in the field of isotopic ecology applied to archaeology has been in constant development for the past two decades, however only a few studies had been made towards this area in Brazil. This study has the objective of generating data to test two contrasting models regarding the strategies of subsistence used by pre-historical societies of Central Bra

4. Presença de dinoflagelados bentônicos potencialmente tóxicos: identificação do perigo em áreas destinadas à maricultura na Baía de Sepetiba, RJ. / Presence of potentially toxic benthic dinoflagellates: identification of hazard in shellfish growing areas in the Sepetiba Bay, RJ.
The malacoculture (cultivation of shellfish) is the second most significant activity of the Brazilian mariculture, where the cultivation of bivalve molluscs (mussels, oysters and scallops) stands out nationally. The bivalves show an excellent nutritional value when they are used as food by humans, containing a great biological value of protein, low in fat, v

5. Orchidaceae nativas da região central de São Paulo, Brasil : florística, interação com forófitos, proposta de novas espécies e propagação in vitro de uma espécie ameaçada de extinção / Native Orchidaceae of the central region of São Paulo, Brazil: floristic, interaction nested with host tree, new species proposed and in vitro propagation of threatened of extinction species
Aiming to know the sorts of Orchidaceae of the central region of the State of São Paulo, from 1996 and more intensively from 2005, visits were carried out in 125 forest fragments of 23 local municípios, with weekly periodicity and also, fortnightly. The collect were assistematics, being each fragment visited in the biggest number of points. The species not

6. Secondary production of brnthonic macrofauna in the intertidal zone in the northern segment of Una beach, on the coast of the estate of São Paulo / Produção secundária da macrofauna bentônica da zona entremarés no segmento norte da praia do Una, litoral sul do estado de São Paulo
This study has as objective to estimate the secondary production and turnover rate (P/B) of the gastropod Hastula cinerea, the isopod Excirolana armata and the decapods Austinixa patogoniensis e Callichirus major in the intertidal zone of Una beach, situated in Estação Ecológica Juréia-Itatins, on the southern coast of the state of São Paulo. For that p

7. Diversidad de ácaros (Acari: Prostigmata, Mesotigmata, Astigmata) asociados a la hojarasca de formaciones vegetales del Parque Universitario de la UCLA, Venezuela
Soil mite diversity (Prostigmata, Mesostigmata, Astigmata) inhabiting in litter-soil layer from a Shrubland and a Deciduous Forest was estimated from December 2000 to November 2001 in the University Park of UCLA (Universidad Centroccidental Lisandro Alvarado), state of Lara, Venezuela. Samplings were made by using pitfall traps along an 1,800 m-transect in b

8. ESTRUTURA DA COMUNIDADE DE MACROINVERTEBRADOS AQUÁTICOS ASSOCIADOS A Mauritia flexuosa LINNAEUS (ARECACEAE), FITOTELMATA, NA AMAZÔNIA CENTRAL, BRASIL
Adult Mauritia flexuosa L. (Arecaceae) palms, known locally as buriti, have large individual axilae that can store substantial volumes of water (phytotelmata). The objectives of the present study were to compare the aquatic macroinvertebrate fauna associated with the axilae of palms occurring in groups and as isolated trees in order to verify the relationshi

9. INFLUÊNCIA DO PULSO DE INUNDAÇÃO NA COMPOSIÇÃO ISOTÓPICA (d13C E d15N) DAS FONTES PRIMÁRIAS DE ENERGIA NA PLANÍCIE DE INUNDAÇÃO DO RIO PARAGUAI (PANTANAL MS) / SEASONAL PATTERN DETERMINING PRIMARY ENERGY SOURCES d13C AND d15N IN THE PARAGUAY RIVER FLOODPLAIN TROPHIC WEB, PANTANAL WETLAND - BRAZIL
The food web of the Pantanal wetland in Brazil was investigated during a complete hydrologic cycle (1998-99) using a multiple stable isotope approach (d13C and d15N) with the goal of identifying the primary carbon sources, which drive the system energy flux. The sampling was done in a representative marginal lake (Baía do Castelo) of Paraguay River floodpla

10. Diversidade dos Cyclopoida (Copepoda, Crustácea) de água doce do estado de São Paulo: taxonomia, ecologia e genética.
In the present work, the diversity of the Copepoda Cyclopoida from Sao Paulo State was studied. Samples of zooplankton were collected along with water samples were collected in 22 Hydrographic Management Units (UHGRH) of the State. Different environments, such as Reservoirs, Ponds, and Rivers were sampled totalizing 207 water bodies. All of them were positio

11. Distribution of Viruses and Dissolved DNA along a Coastal Trophic Gradient in the Northern Adriatic Sea
The distribution of viral and other microbial abundances as well as the concentrations of dissolved DNA (D-DNA) along a trophic gradient in the northern Adriatic Sea were determined. Virus abundances, covering a range of 1.2 × 109 to 8.7 × 1010 liter-1 were on average 2.5-fold higher in eutrophic than in mesotrophic stations. A 2.5-fold enrichment was also
