1. Os Nematoda da plataforma continental da região sudeste brasileira sob a influência da Água Central do Atlântico Sul: Cabo Frio (RJ) e Ubatuba (SP) / The Nematoda of the continental shelf of the Brazil\ s southern region under the influence of the South Atlantic Central Water intrusion: Cabo Frio (RJ) and Ubatuba (SP)
Meiofauna is an important component of the marine benthic ecosystem as its densities are usually high in continental shelf sediments and respond quickly to environmental changes. Nematoda is the dominant group among meiofauna organisms, is highly diverse and can be used, as well as meiofauna, as a tool for natural and anthropogenic impacts monitoring. This s

2. Relação solo-relevo-substrato geológico na planíce costeira de Bertioga (SP) / Soil-relief-geologic substract relationship on the coastal plain of Bertioga (SP)
Knowledge of the chronology, relief, geology and soils in sedimentary coastal environments is relevant for their interpretation, reconstitution and conservation. In Bertioga, São Paulo State Brazil, several sections of the Pleistocene and Holocene morphostratigraphic costal plain units are preserved in the landscape. This thesis seeks the perception of the

3. Reconstrução paleoambiental (vegetação e clima) no Parque Estadual da Ilha do Cardoso - SP durante o Quaternário tardio / Palaeoenvironmental reconstruction in the parque Estadual da Ilha do Cardoso, São Paulo State during the late Quaternary
Este estudo foi desenvolvido no Parque Estadual da Ilha do Cardoso (PEIC) e no Parque Estadual Carlos Botelho (PECB), na região sudeste do Brasil. A área é caracterizada pela presença de vegetação nativa de Floresta Atlântica de Encosta e no caso do PEIC, também por Restinga e vegetação de manguezal. Foram coletadas amostras de solos a partir de tr

4. Análise estratigráfica de alta resolução do intervalo praguiano-neoemsiano (Formação Ponta Grossa), na borda leste da Bacia do Paraná, com base em dados geoquímicos e sedimentológicos / High resolution stratigraphic analysis of praguian-neoemsian interval (Ponta Grossa Formation), at eastern edge of Parana Basin, with base on geochemical and sedimentologic datas
This work is the result of detailed stratigraphic analysis on the sedimentary record of Praguian?Emsian later interval, established on core samples of four wells in the Paleozoic outcrop section, eastern edge of Paran? Basin. Data set was obtained by means of sedimentology, gamma spectrometry and organic geochemistry (total organic carbon and pirolysis Rock-

5. Species assembly rules and the biodiversity-ecosystem functioning relationship / Regras entre assemblÃias de espÃcies: relaÃÃo entre biodiversidade e funcionamento do ecossistema
The biological diversity of ecosystems has important implications for their functioning. However, in order for reliable predictions to be made on the effects of species extinctions and/or additions on particular ecosystem functions, accurate knowledge is required on the ways in which species interact. These interactions in turn are important drivers of commu

6. Survival without recovery after mass extinctions
Because many survivors of mass extinctions do not participate in postrecovery diversifications, and therefore fall into a pattern that can be termed “Dead Clade Walking” (DCW), the effects of mass extinctions extend beyond the losses observed during the event itself. Analyses at two taxonomic levels provide a first-order test of the prevalence of DCWs by

7. Diversity and Dynamics of a North Atlantic Coastal Vibrio Community
Vibrios are ubiquitous marine bacteria that have long served as models for heterotrophic processes and have received renewed attention because of the discovery of increasing numbers of facultatively pathogenic strains. Because the occurrence of specific vibrios has frequently been linked to the temperature, salinity, and nutrient status of water, we hypothes
