Host specialization in highly diverse tropical forests may be limited by the low local abundance of suitable hosts. To address whether or not fungi in a low-diversity tropical forest were released from this restriction, fruiting bodies of polypore basidiomycete fungi were collected from three species of mangroves (Avicennia germinans, Laguncularia racemosa, and Rhizophora mangle) in a Caribbean...

Hochiminh City environs have more than 45,000 ha of coastal plain soils which to be continued to the South by the great mangrove forest in Camau peninsula. How to protect and afforest mangroves successfully on these soils when using them also for aquaculture (shrimp, fish, crab, mollusc, etc.)? An answer to this question is now urgently needed. Dealing with the study on soil genesis/ geography ...

heavy metals in the surface sediments of the two coastal ecosystems of cochin, southwest india were assessed. the study intends to evaluate the degree of anthropogenic influence on heavy metal concentration in the sediments of the mangrove and adjacent estuarine stations using enrichment factor and geoaccumulation index. the inverse relationship of cd and zn with texture in the mangrove sedimen...

Reproduction is certainly the main mechanism by which to guarantee species continuity, being a result of adaptative processes determined by evolutionary pressures to improve offspring survival (Hartnoll & Gould 1988). Breeding period is defined as the time interval in which ovigerous females may be found. According to Sastry (1983), it is the result of the complex interactions of endogenous and...

Mangroves are woody plants located in tropical and subtropical intertidal coastal regions. The mangrove ecosystem is becoming a hot spot for natural product discovery and bioactivity survey. Diverse mangrove actinomycetes as promising and productive sources are worth being explored and uncovered. At the time of writing, we report 73 novel compounds and 49 known compounds isolated from mangrove ...

Mangrove wetlands are economically and ecologically important ecosystems and accurate assessment of these wetlands with remote sensing can assist in their management and conservation. This study was conducted to evaluate airborne AISA hyperspectral imagery and image transformation and classification techniques for mapping black mangrove populations on the south Texas Gulf coast. AISA hyperspect...

43 surface sediment samples from Kemaman mangrove forest, Terengganu were analyzed for sediment characteristic (mean, sorting and skewness) off two seasons (dry season and wet season) by using the Particle Size Analyzer (PSA) after digest the sample with Hydrogen Peroxide (H2O2) and Hydrochloric Acid (HCl). There is a significant (P<0.05) relationship between sediment characteristic with the se...

In the present study, metagenomic technique and fosmid vectors were used to construct a library of clones for exploring the biotechnological potential of mangrove soils by isolation of functional genes encoding hydrolytic enzymes. The library was built with genomic DNA from the soil samples of mangrove sediments and the functional screening of 1824 clones (~64 Mbp) was performed to detect the h...

Wave energy and storm surges threaten coastal ecology and nearshore infrastructures. Although coastal structures are conventionally constructed to dampen the wave energy, they introduce tremendous damage to the ecology of the coast. To minimize environmental impact, ecofriendly coastal protection schemes should be introduced. In this paper, we discuss an example of an innovative mangrove rehabi...

Sediment is an important part of heavy metal cycling in the coastal ecosystem, acting as a potential sink and source inorganic organic contaminants environmental conditions change. The productivity mangroves utterly dependent on sediment enrichment. Moreover, mangrove can trap pollutants discharged by households, industries, agriculture activities. In this regard, it essential to assess quality...
