25. Comunidade de CrustÃceos DecÃpodos InfralitorÃneos dos Recifes da Praia de Porto de Galinhas (PE)
Northeastern Brazilian coral reefs, as found in Porto de Galinhas beach â PE, are known as areas of complex and diverse biological interactions and high biological productivity (primary productivity). In addition, they represent a reproductive zone, and serve as nursery, shelter and alimentation source for a major part of the marine fauna. Porto de Galinhas

26. "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

27. Impacto ambiental decorrente das atividades agrícolas no município do Conde - Paraíba, com ênfase no assentamento rural de Barra de Gramame / ENVIRONMENTAL IMPACT CAUSED BY AGRICULTURAL ACTIVITIES IN THE MUNICIPALITY OF CONDE, PARAÍBA: EMPHASIS ON THE RURAL SETTLEMENT OF BARRA DE GRAMAME
Neste trabalho realizou-se um estudo dos impactos ambientais causados pelas atividades agrícolas e identificação das áreas potencialmente degradadas ou degradadas por esta atividade. As áreas selecionadas para desenvolver este estudo foram: o município do Conde localizado no litoral sul do Estado da Paraíba Brasil, entre as coordenadas geográficas de

28. Distribuição vertical e flutuação sazonal da macrofauna vágil associada a Sargassum cymosum C. Agardh, na praia do Lázaro, Ubatuba, São Paulo, Brasil
Seasonal fluctuations and depth distribution of the vagile macrofauna associated with Sargassum cymosum at Lazaro beach, Ubatuba, São Paulo State, were evaluated through density comparison of higher taxonomic groups among three depth intervals in four periods of the year. Ten groups were identified and among them gammarid and caprellid amphipods were numeri

29. Polychaete zonation on sandy beaches of São Sebastião Island, São Paulo State, Brazil
Este trabalho foi realizado na região entremarés das praias Barra Velha, Perequê e Engenho d'Água, situadas na Ilha de São Sebastião (Estado de São Paulo, Brasil), com o objetivo de estudar a composição, abundância e zonação da taxocenose dos poliquetas. Quatro setores estruturalmente diferentes foram delimitados, sendo dois na Barra Velha (I e I

30. Sedimentos superficiais da plataforma continental interna do estado da ParaÃba
The internal continental shelf in the state of ParaÃba was divided into three sectors: central and northern, considering the coastal line morphology, bathymetric features and sedimentary information. The southern sector comprises the region extending the latitude 7Â35â00âS to Branco Cape. The coastal line is basically staight, trending N-S, characterized

32. Intraspecific diversity and ecological zonation in coral-algal symbiosis.
All reef-building corals are obligately associated with photosynthetic microalgal endosymbionts called zooxanthellae. Zooxanthella taxonomy has emphasized differences between species of hosts, but the possibility of ecologically significant zooxanthella diversity within hosts has been the subject of speculation for decades. Analysis of two dominant Caribbean

33. Influence of Potassium in the Agar Medium on the Growth Pattern of the Filamentous Fungus Fusarium solani
A decrease in the concentration of K+ ions below 3 mM in agar medium which also contained starch, casein hydrolysate, MgSO4, and K2HPO4 changed the growth pattern of Fusarium solani illuminated in diurnal 12-h light/12-h dark cycles from zonation to a feathery growth mode. Rubidium or cesium ions could replace potassium, but lithium, sodium, and the bivalent

34. Modification of the Period of a Noncircadian Rhythm in Nectria cinnabarina1
The sporulation rhythm in Nectria cinnabarina Tode ex Fr. is expressed by either concentric rings or spirals. The period is inversely proportional to the temperature and does not approach 24 hours; the rhythm is therefore noncircadian. The period of the zonation rhythm is lengthened by culturing the fungus on a dialysis membrane over the agar surface, on med

35. The terminal Paleozoic fungal event: evidence of terrestrial ecosystem destabilization and collapse.
Because of its prominent role in global biomass storage, land vegetation is the most obvious biota to be investigated for records of dramatic ecologic crisis in Earth history. There is accumulating evidence that, throughout the world, sedimentary organic matter preserved in latest Permian deposits is characterized by unparalleled abundances of fungal remains

36. Methane Consumption in Temperate and Subarctic Forest Soils: Rates, Vertical Zonation, and Responses to Water and Nitrogen †
Rates of methane consumption were measured in subarctic coniferous and temperate mixed-hardwood forest soils, using static chambers and intact soil cores. Rates at both sites were generally between 1 and 3 mg of CH4 m-2 day-1 and decreased with increasing soil water contents above 20%. Addition of ammonium (1 μmol g of soil-1) strongly inhibited methane oxi
