13. RelaÃÃes ecolÃgicas entre Melampus coffeus (Gastropoda: Pulmonata) e a serapilheira no mÃdio estuÃrio do rio Pacoti, Cearà / Ecological relations between Melampus coffeus (Gastropoda: Pulmonata) and the leaflitter in the middle estuary of Pacoti river, CearÃ
The litter is essential for the nutrients and organic matter cycles in forests ecosystems. These vegetal detritus are a food source to many groups of animals that act directly on the litter decomposition. Litter also seems to provide microhabitats and works as a shelter for many individuals of the mangrove fauna. The gastropod Melampus coffeus (Linnaeus, 175

14. Impactos Socioambientais no EstuÃrio do Rio Jaguaribe: o Caso da Cidade de Aracati-Ce. / Social and Environmental Impacts on River Estuary Jaguaribe: If the City Aracati-Ce.
The Jaguaribe River was fundamental to the development of the city of Aracati. However, during recent decades a degradation of the fluvial and marine ecosystems caused by several environmental impacts has been perceived. Analyzing the social and environmental impacts at the estuary of the Jaguaribe River, highlighting the process of urban expansion from 1980

15. Bioemulsifier production by Microbacterium sp. strains isolated from mangrove and their application to remove cadmiun and zinc from hazardous industrial residue
The contamination of ecosystems with heavy metals is an important issue in current world and remediation technologies should be in according to environmental sustainability concept. Bioemulsifier are promising agents to be used in metal removal and could be effective to many applications in environmental industries. The aims of this work was screening the po

16. Molecular characterization of cyanobacteria isolated from mangrove ecosystem of the State of São Paulo and identification of natural products / Caracterização molecular de cianobactérias isoladas de ecossistema manguezal do Estado de São Paulo e identificação de produtos naturais
O gene de RNAr 16S tem sido amplamente utilizado na inferência filogenética de organismos procariotos, entretanto, sequências desse gene de cianobactérias isoladas de manguezais brasileiros são inexistentes. Neste estudo, 42 sequências inéditas do gene de RNAr 16S de cianobactérias isoladas de manguezais brasileiros foram geradas. Na análise BLAST a

17. Cyanobacteria in mangrove ecosystems: isolation, morphology and genetic diversity / Cianobactérias em ecossistemas de manguezais: isolamento, morfologia e diversidade genética
Manguezais são ecossistemas de transição entre ambientes terrestres e marinhos encontrados em regiões tropicais e subtropicais. A ampla faixa de variações de salinidade e teor oxigênio, típica desses ambientes, está entre os principais fatores condicionantes da colonização e desenvolvimento da biota. Apesar disso, são ambientes com elevada produ�

18. Fatores externos e internos que alteram a vida do homem e o ecossistema Manguezal do Rio Jordão - Pernambuco / External and internal factors that alter the life of man and the mangrove ecosystem of the Jordan River - Pernambuco
Geography, presented here as an interdisciplinary science, with interface in a lot of segments of the knowledge. Its branches make this science a plural science in the academic traditionalism. It allows us to work issues on chronologic, biologic, human and nature as it will be presented in this study. A question that bases this work line is the theory of the

19. Diversity of endophytic diazotrophic bacteria of red mangrove (Rhizophora mangle) and evalution of the biotechnological potential. / Diversidade de bactérias diazotróficas endofíticas de mangue vermelho (Rhizophora mangle) e avaliação do potencial biotecnológico.
Mangroves are considered a coastal ecosystem, located in the transition between the terrestrial and marine environments. This environment is typical of tropical and subtropical regions and is found throughout the world, mainly in Brazil, Indonesia and Australia. The occurrence of a large amount of organic matter enhances the fact that microorganisms are impo

20. Ecogenômica de archaea e monitoramento de comunidades de procariotos redutores de sulfato: aplicações na indústria de petróleo e gás
The human activities responsible for the ambient degradation in the modern world are diverse. The industrial activities are preponderant in the question of the impact consequences for brazilian ecosystems. Amongst the human activities, the petroliferous industry in operation in Potiguar Petroliferous Basin (PPB) displays the constant risk of ambient impacts

21. AnÃlise de comunidades microbianas de solo de manguezal por T-RFLP e microarranjos de DNA / AnÃlise de comunidades microbianas de solo de manguezal por T-RFLP e microarranjos de DNA
The mangroves are essistemas important and productive, found along the coastline of tropical and subtropical regions. Important processes such as nutrient cycling, are directly connected to the activity of soil microbial communities. Given its strategic position the mangroves are very impacted the world. In Brazil, important areas such as the Bay of All Sain

22. INDICADORES POPULACIONAIS E ECOLÓGICOS DE PEIXES-BOIS-MARINHOS (Trichechus manatus manatus) EM DUAS ÁREAS DE MANGUEZAIS E MARISMAS NO MARANHÃO / POPULATION AND ECOLOGICAL INDEX FOR MANATEES (Trichechus manatus manatus) IN TWO MANGROVES AND SALT-MARSHES AREAS OF MARANHÃO
The Brazilian north coast has the largest continuous area of mangroves on the planet and hosts large groups of manatees, aquatic mammal critically endangered. This research examines the efforts of fix point methodology of observation of manatees on relevant sites of occurrence, from data collected while on the beach in Guarapiranga (GUA), São José de Ribam

24. Bacterial and Archaeal diversity in mangrove and marisma soils / Diversidade de Bacteria e Archaea em solos de mangue e marisma
The bacterial diversity in mangrove (Brazil) and marisma (Espanha) soils are largely unknown. Bacterial communities participate in biogeochemicals processes that occurs in soils of estuarine ecosystems. Determinations of the bacterial communities structures and diversity can occur in function of different physico-chemical conditions, reflecting in the biogeo
