Studies on actinobacteria of marine habitats gaining international importance due to its proven abilities of novel compound production. Information on actinobacteria of the mangrove environments is less and hence the present study was carried out in the different mangrove environment of Bhitarkanikka, Orissa. A total of 116 actinobacterial colonies were recorded from 30 mangrove and marine sedi...

Mangrove ecosystems played a vital role in buffering the force of the tsunami waves and in protecting the human inhabitations. Even before the Tsunami, Sri Lanka has been experiencing rapid loss of mangrove ecosystems mainly due to anthropogenic factors including unprecedented growth of the tourism sector. In addition to the provision of ecosystem functions, the mangroves are instrumental in su...

Mangrove ecosystem is well known for the productivity. Fungi play an important role in the nutritive cycle and support the mangrove ecosystem. In the present investigation the authors tries to elucidate marine fungi in selected mangrove ecosystem of North Malabar region of Kerala. 30 marine fungi including 19 Ascomycetes, 1 Basidiomycete and 10 Mitosporic fungi were encountered. Backwater suppo...

Understanding the dynamics of mangroves at the species level is the key for securing sustainable conservation of mangrove forests around the globe. This study demonstrates the capability of the hyper-dimensional remote sensing data for discriminating diversely-populated tropical mangrove species. It was found that five different tropical mangrove species of Southern Thailand, including Avicenni...

Mangrove roots in the well-protected channels and ponds among dense mangrove stands provide very similar habitats for sponges in the Twin Cays and Pelican Cays and harbor extraordinarily dense and diverse sponge communities in both locations. The species of sponges are very different, however, possibly because of an important difference in context: the Twin Cays mangrove roots are embedded in p...

Sesarmid crabs are reported to dominate the Indo West-Pacific mangroves and consume huge amounts of mangrove leaves and detritus. Neosarmatium trispinosum Davie (1994) is common in the landward mangroves of the Ryukyu Islands in southern Japan. Stomach contents of the crabs collected from Okinawa, Miyako and Iriomote Islands showed that their diet consisted of mainly mangrove leaves with small ...

The diversity of phosphobacteria in Manakudi mangrove ecosystem of Tamil Nadu was carried out in root and rhizosphere soil samples. The counts of phosphobacteria were found higher in root samples than in soil samples particularly in Hymenachene acutigluma. The abundance of phosphobacterial diversity in Manakudi mangrove showed high degree of positive correlation with the content of phosphate in...

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...

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...
