1. Grazing Scar Characteristics Impact Degree of Fungal Facilitation in Spartina alterniflora Leaves in a South American Salt Marsh
Grazing scars of burrowing crabs and Hemiptera insects were simulated on leaves of the salt marsh grass Spartina alterniflora. Simulations of crab feeding generated two-fold higher fungal (ergosterol) content in leaves in comparison to that generated by insect scar simulations (1.26 ±0.55 and 0.57 ±0.25 µg per cm², respectively). This study provided evid

2. Biodiversity of the oleaginous microorganisms in Tibetan Plateau
Microbial lipids, which are also known as single cell oils (SCO), are produced by oleaginous microorganisms including oleaginous bacteria, yeast, fungus and algae through converting carbohydrates into lipids under certain conditions. Due to its unique environment having extremely low temperature and anoxia, the Tibetan Plateau is amongst the regions with num

3. Composição e estrutura da comunidade de insetos de uma marisma da Ilha da Pólvora (Rio Grande, Brasil) / Composition and structure of the insect community of a salt marsh of Pólvora Island (Rio Grande, Brazil)
Insetos são membros de vital importância das comunidades bióticas. Atualmente, constituem o grupo dominante de animais na Terra. Porém, mesmo sendo um grupo de elevada importância nos mais diversos ambientes, a sua dados sobre este grupo são praticamente inexistentes nas marismas brasileiras. Desta forma com o objetivo de descrever a composição e a e

5. Diatomáceas (Bacillariophyta) em sedimentos superficiais de marismas na planície costeira do Rio Grande do Sul, Brasil
O estudo objetivou avaliar a composição, a riqueza e a diversidade da comunidade de diatomáceas no sedimento das marismas da laguna dos Patos. Duas expedições foram realizadas, a primeira em junho de 2002, e, a segunda em março de 2008 amostrando um total de cinco pontos. Os resultados demonstraram que esta comunidade é biodiversa, composta em 64% por

6. 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

7. Characterization of the humic substances extracted from the soil of the Pai Matos mangrove forest (Cananéia, SP, BR) and Spanish salt marshes (Galicia and Valencia) / Caracterização das substâncias húmicas extraídas do solo do manguezal de Pai Matos (Cananéia, SP, BR) e de marismas da Espanha (Galícia e Valência)
Os objetivos deste estudo foram: 1) avaliar por meio da análise elementar (C, N, H, S, O), Ressonância Paramagnética Eletrônica (RPE), e Espectroscopia de Infravermelho com Transformada de Fourier (FTIR) às características dos ácidos húmicos (AHs) extraídos do solo do manguezal de Pai Matos (Cananéia-SP-BR) sob diferentes tipos de vegetação (Rhiz

8. Determinação da composição isotópica de estrôncio em águas naturais: exemplos de sua aplicação em águas subsuperficiais da zona costeira na região Bragantina-PA
Analytical procedures used for determining the concentrations and isotope composition of strontium in subsurface waters, by mass spectrometry, are described. Sampling was performed in coastal plateaus, salt marsh and mangrove environments in the coastal region of Pará. Coastal plateau waters have delta87Sr between 1.51 and 6.26‰ and Sr concentration bello

9. Nota complementar sobre a composição ictiofaunística da Baía de Guaratuba, Paraná, Brasil
The utilisation of multiple gears and the surveying of other areas than that of mangrove habitats have increased in 27 the number of fish species known in the Guaratuba Bay, an estuarine ecosystem located in the southern of Brazilian coastal region (25º52'S, 48º39'W). The new occurrence of a typically freshwater species (Pimelodidae) and of several Clupeif

10. Anthropogenic modification of New England salt marsh landscapes
Salt marshes play a critical role in the ecology and geology of wave-protected shorelines in the Western Atlantic, but as many as 80% of the marshes that once occurred in New England have already been lost to human development. Here we present data that suggest that the remaining salt marshes in southern New England are being rapidly degraded by shoreline de

11. Arylsulfatase Activity in Salt Marsh Soils †
The presence of arylsulfatase(s) was confirmed in salt marsh soils. The temperatures of maximum activity and inactivation, the pH range over which the enzyme was active, and the Km values were similar to those of soil enzymes. Unlike soil arylsulfatases, however, the salt marsh enzymes do not appear to be repressed by sulfate. It is postulated that these enz

12. Rapid shoreward encroachment of salt marsh cordgrass in response to accelerated sea-level rise
The distribution of New England salt marsh communities is intrinsically linked to the magnitude, frequency, and duration of tidal inundation. Cordgrass (Spartina alterniflora) exclusively inhabits the frequently flooded lower elevations, whereas a mosaic of marsh hay (Spartina patens), spike grass (Distichlis spicata), and black rush (Juncus gerardi) t
