1. Geospatial analysis of the effects of tsunami on coral and mangrove ecosystems of Mayabunder in Andaman Islands, India
Abstract Mangroves and coral reefs are among the major ecosystems of tropical and subtropical coastlines. The Andaman group of islands, situated at the juncture of Bay of Bengal and Indian Ocean, are one of the richest coastal ecosystems of India in terms of biodiversity. Since the tsunami waves of 2004 affected this region severely, the outer fringes as wel

2. The rates and players of denitrification, dissimilatory nitrate reduction to ammonia (DNRA) and anaerobic ammonia oxidation (anammox) in mangrove soils
Abstract Mangroves are ecosystems located in the transition zone between land and sea, characterized by periodic flooding that confer to its unique characteristics. Little is known about the transformation of nutrients that occur during the organic matter degradation in this system. In this study, we monitor the nitrogen transformations in soils from three m

3. Mangrove endophyte promotes reforestation tree (Acacia polyphylla) growth
ABSTRACT Mangroves are ecosystems located in the transition zone between land and sea that serve as a potential source of biotechnological resources. Brazil's extensive coast contains one of the largest mangrove forests in the world (encompassing an area of 25,000 km2 along all the coast). Endophytic bacteria were isolated from the following three plant spec

4. Host-exclusivity and host-recurrence by wood decay fungi (Basidiomycota - Agaricomycetes) in Brazilian mangroves
ABSTRACT This study aimed to investigate for the first time the ecological interactions between species of Agaricomycetes and their host plants in Brazilian mangroves. Thirty-two field trips were undertaken to four mangroves in the state of Pernambuco, Brazil, from April 2009 to March 2010. One 250 x 40 m stand was delimited in each mangrove and six categori

5. First Assessment of Carbon Stock in the Belowground Biomass of Brazilian Mangroves
ABSTRACT Studies on belowground roots biomass have increasingly reported the importance of the contribution of this compartment in carbon stock maintenance in mangrove forests. To date, there are no estimates of this contribution in Brazilian mangrove forests, although the country has the second largest area of mangroves worldwide. For this study, trenches d

6. Endophytic fungus Purpureocillium sp. A5 protect mangrove plant Kandelia candel under copper stress
Abstract Mangrove is an important ecosystem in the world. Mangrove ecosystems have a large capacity in retaining heavy metals, and now they are usually considered as sinks for heavy metals. However, the mechanism of why the soil of mangrove ecosystems can retain heavy metal is not certain. In this research, endophytic fungus Purpureocillium sp. A5 was isolat

7. Diversity and distribution of epiphytic bromeliads in a Brazilian subtropical mangrove
ABSTRACT It is not unusual to find epiphytic bromeliads in mangroves, but most studies on mangrove vegetation do not record their presence. This study aimed to evaluate the diversity and distribution of epiphytic bromeliads in a subtropical mangrove. The richness, abundance and life form (atmospheric and tank) of bromeliads were recorded and compared among h

8. Bacterial diversity in relatively pristine and anthropogenically-influenced mangrove ecosystems (Goa, India)
To appreciate differences in benthic bacterial community composition at the relatively pristine Tuvem and the anthropogenically-influenced Divar mangrove ecosystems in Goa, India, parallel tag sequencing of the V6 region of 16S rDNA was carried out. We hypothesize that availability of extraneously-derived anthropogenic substrates could act as a stimulatant b

9. Ardra profiles of bacteria and archaea in mangrove sediments with different levels of contamination in the estuarine complex of Paranaguá, Brazil
The mangrove's sediments from the coastal areas under human activities may contain significant contaminations by hydrocarbons, even when there are no visual evidences of it. The microorganisms are essential to these ecosystems, especially in the control of their chemical environment. Sediment samples were collected in two regions under different environment

10. Bryoflora of the municipalities of Soure and Cachoeira do Arari, on Marajó Island, in the state of Pará, Brazil
This study aims to investigate the richness and ecological aspects (ecosystem and substrate) of mosses and liverworts at two municipalities on Marajó Island, in the state of Pará, Brazil. The study area (6615 km²) encompasses the municipalities of Soure and Cachoeira do Arari. Bryophytes were collected from the 10th to the 16th of January, 2007, during ra

11. Diversidade e potencial biotecnológico de Pseudomonas spp. de sedimentos de manguezais. / Diversity and biotechnological potential of Pseudomonas spp. from mangrove sediments.
Os manguezais estão localizados na interface entre o continente e o oceano em regiões intertropicais, possuindo condições ambientais únicas. O objetivo deste trabalho foi avaliar a diversidade e o potencial biotecnológico da comunidade de Pseudomonas spp. em sedimentos de manguezais com diferentes estágios de preservação, no Estado de São Paulo.

12. Microbial diversity in Brazilian mangrove sediments: a mini review
The importance and protection of mangrove ecosystems has been recognized in Brazilian Federal law since 1965. Being protected in law, however, has not always guaranteed their protection in practice. Mangroves are found in coastal and estuarine locations, which are prime real estate for the growth of cities, ports and other economic activities important for B
