1. QUANTIFICATION OF CARBON IN FOREST NECROMASS: STATE OF THE ART
ABSTRACT Necromass play a significant ecological function, including the deposition of organic matter, which is essential for carbon cycling in forest ecosystems. Despite the devoted attention to the role of forest necromass into the global carbon cycle, international organizations such as IPCC and FAO have reported the lack of compatible data concerning the

3. Carbon and nutrient stocks of three Fabaceae trees used for forest restoration and subjected to fertilization in Amazonia
ABSTRACT Amazonia is crucial to global carbon cycle. Deforestation continues to be one of the main causes of the release of C into the atmosphere, but forest restoration plantations can reverse this scenario. However, there is still diffuse information about the C and nutrient stocks in the vegetation biomass. We investigated the carbon and nutrient stocks o

4. Larvae of migratory fish (Teleostei: Ostariophysi) in the lotic remnant of the Paraná River in Brazil
ABSTRACT Fish larvae and adults are morphologically distinct from each other and have different ecological requirements. Research on the dynamics of ichthyoplankton provides valuable information about the early stages of the life cycle of fish. This study analyzed the temporal and spatial distribution of the larval stages of three migratory species - Salminu

5. Biodiversity, distribution and abundance of shrimps Penaeoidea and Caridea communities in a region the vicinity of upwelling in Southeastern of Brazil
This study evaluated the spatial-temporal distribution of the abundance of Caridean and Penaeid shrimps during the period of two years in the coastal region of Macaé, state of Rio de Janeiro, southeastern Brazil, using ecological indices (Shannon-Wiener diversity and Pielou's equitability). Monthly samples were carried out from March 2008 to February 2010 d

6. Uso do habitat e identificação de unidades populacionais de pequenos cetáceos do Atlântico Sul-Ocidental através de isótopos estáveis e elementos traço / Habitat use and populational inits identification of small cetaceans of the Western South Atlantic through stable isotopes and trace elements
O objetivo geral desta tese foi identificar unidades populacionais (estoques ecológicos) e determinar padrões de uso de habitat de pequenos cetáceos no Atlântico Sul Ocidental por meio de traçadores químicos. A análise de isótopos estáveis foi utilizada como ferramenta para identificar estoques ecológicos de botos-cinza (Sotalia guianensis) e tonin

7. Implantação da piscicultura familiar com pescadores e agricultores assentados no Município de Lucena-PB
Fishing is a very important activity for the provision of protein, but as a result of the heavy pressure from extractive fishing and above the limits of carrying capacity of populations of commercial species, many stocks are at or above the limit of exploration, which has resulted in decreased populations of many animals, including driving some to extinction

8. Avaliação limnológica da lagoa central (Município de Lagoa Santa - MG): uma abordagem espacial
The concern about the decrease of ecological health of freshwater resources has been increasing dramatically in recent years. Therefore, there is a huge demand of finding new technologies aimed at the recovery and conservation of freshwater resources specially in the tropical belt. Accordingly, the application of new technologies such as GIS (Geographic Info

9. Fauna do solo e outros atributos edáficos como indicadores da qualidade ambiental em áreas com Araucaria angustifolia no Estado de São Paulo / Soil fauna and others edaphics attributes as environmental quality indicators in areas with Araucaria angustifolia in São Paulo State, Brazil
The study of biological soil quality indicators in areas with Araucaria is very important to understand ecological processes in these systems, since groups of the soil fauna are major factors in the decomposition and mineralization of organic matter, as well as modifiers of soil physical, chemical and biological properties and processes. The objective of thi

12. Influência da aplicação do lodo de esgoto (Biossólido) sobre a concentração e o estoque de nutrientes na biomassa do sub-bosque, na serapilheira e no solo de um talhão de E. grandis. / Influence of sewage sludge application (biosolids) on the concentration and stock of nutrients in the understory biomass, litter and soil in a stand of Eucalyptus grandis.
The increasing of urban population generates the need for an ecological and social acceptable disposal of sewage sludge produced by waste treatment plants. Therefore, the use of the sewage sludge (biosolid) as fertilizer and soil conditioner in forests plantations may be a suitable solution, becoming possible the increment of renewable wood production.
