13. Sucessão ecológica em parcelas orgânicas de madeira, macroalgas e em carcassas de baleia no mar profundo; e similaridade de espécies entre habitats redutores no talude continental da Califórnia (Pacífico Nordeste) / Whales, wood and kelp islands in the deep-sea: ecological succession and species overlap with other chemosynthetic habitats in the Californian continental slope (NE Pacific)
Sunken parcels of macroalgae, wood and whale carcasses provide important oases of organic enrichment at the deep-sea floor, but sediment community structure and succession around these habitat islands are poorly evaluated. We experimentally implanted parcels of kelp and wood falls nearby a 30-ton deep-sea whale-fall at 1670 m in the Santa Cruz Basin (SCr; NE

14. IMPLICAÇÕES LIMNO-ECOLÓGICAS DERIVADAS DA INFECÇÃO VIRAL NO PLÂNCTON
Virus are described as the most abundant and dynamic organisms in the aquatic environment, influencing communities composition and biogeochemical and ecological processes. These organisms are responsible for great part of the bacterial and phytoplanktonic mortality, for algal blooms decrease and for increasing the nutrients and carbon availability. Many prev

15. Pre-historic ocupations humans at Maranhense coast: an study of Bacanga Shell Midden at São Luís Island-Maranhão / Ocupações humanas pré-históricas no litoral maranhense: um estudo arqueológico sobre o sambaqui do Bacanga na ilha de São Luís - Maranhão
The present dissertation discusses about the pre-historic occupation at São Luís Island-Maranhão, from the archaeological study realized at Bacanga Shell Mound, that appointed material vestiges of the fishing-collecting-hunters and ceramists populations that settled in the region, around 6.600 years before present and remained living this settlement until

16. Environmental constraints structuring fish assemblages in the river Paraíba do Sul watershed: Land use condition, habitat and physico-chemical water quality. / Condicionantes ambientais estruturadoras das assembléias de peixes da bacia do rio Paraíba do Sul: Condição do uso da terra, do habitat físico e qualidade físico-química da água.
Structure and dynamic of the Paraíba do Sul fish assemblages and their relationship with environmental constraints in both regional (e.g. altitude, area of drainage, flow and land use) and local (microhabitat and physico-chemical) scales were studied. A fish sampling programme was carried out in the whole extension of the main channel (1100 km) and in the s

17. Densidade de recursos florais em múltiplas escalas espaciais: conseqüências para a interação planta-polinizador e demografia de Abutilon rufinerve (Malvaceae) / Floral resource availability in multiple hierarchical spatial scales and its consequences to plant-pollinator interaction and demography of Abutilon rufinerve (Malvaceae)
Heterogeneity is a remarkable characteristic of biological systems. This thesis is about the influence of heterogeneity on plant-pollinator interaction and on demography of a tropical treelet Abutilon rufinerve. With an approach of hierarchical scales of patch structure we: 1. characterized the spatio-temporal variation on the availability of floral resource

18. Análise da turbidez na planície de inundação de Curuaí (PA, Brasil) integrando dados telemétricos e imagens MODIS/TERRA / Analysis of the turbidity in the Curuaí floodplain (PA, Brazil) integrating telemetric data and MODIS/TERRA images
The hypothesis that motivated the accomplishment of this research was: the turbidity has a variation in response of flood pulse in the Curuai floodplain and this response could be folloied with the use of satellite images and in-situ data (ground data and telemetric data). Thus, the objective of the work was evaluate the turbidity behavior in the Curuai floo

20. Limnologia da barragem de acauã e codeterminantes socioeconômicos do seu entorno : uma nova interação do limnalogo com sua unidade de estudo
The main objective of this dissertation is to describe the limnological co-determinatives variations in temporal (monthly) and spatial (vertical/horizontal) scales of the Acauã reservoir by diagnosing its current trophic state. Monthly samples were collected and analyzed between August 2004 and July 2005. They were collected in six different regions of the

21. A comunidade de invertebrados bentônicos nos reservatórios de Promissão, Nova Avanhandava e Três Irmãos (Baixo Rio Tietê - SP).
The aim of the present study was to characterize the benthic community of Promissão, Nova Avanhandava and Três Irmãos reservoirs, in relation to the composition of taxa, population densities and also to verify the occurrence of exotics mollusks in this reservoir system. Moreover, it aimed to evaluate possible relations between the physical and chemical ch

22. "Ecologia de manguezais: desenvolvimento espaço-temporal no sistema costeiro Cananéia-Iguape, São Paulo, Brasil" / Mangrove Ecology: spatial and temporal development at Cananéia-Iguape Coastal System, São Paulo, Brazil
Mangrove forests get developed in distinct patterns, depending on geomorphological and environmental scenarios. Its spatial and temporal development was studied in a landscape ecology context, at the Cananéia-Iguape Coastal System. Stand and Site hierarchical levels had been used to analyze mangrove forests. At Stand level, aerial photography processing alo

23. Padrões de distribuição genotipica em litorinideos (Mollusca : Gastropoda) da costa brasileira / Genotypic distribution patterns in littorinids (Mollusca : Gastropoda) from Brazilian coast
One of the main questions in biology is the link between a species ecology and its evolution. Evaluating the relationship between the geographical scale over which populations differ genetically and the species dispersal ability is a way to understand how this link is established. Spatial variation in allellic frequencies of natural populations may be explai

24. Ecologia e genetica da mandioca na agricultura itinerante do litoral sul paulista : uma analise espacial e temporal
This study focuses the inter-relationships between the men, the farm environment, and the domesticated crop species, under the perspective of the evolutionary dynamics of cultivated plants. The main objective of this study was to evaluate the features related to the conservation, loss, and amplification of the varietal diversity of manioc (Manihot esculenta
