The m. 2014). We reviewed the geological record of mangroves based on fossil pollen, fruits, and wood evidence of Nypa, Avicennia, Sonneratia, Rhizophoraceae, and mangrove associates to trace the origin, distribution, extinction, and range contraction of paleo‐mangroves during the Late Cretaceous–Miocene time. MATERIAL AND METHODS MANGROVE DEFINITIONS Proper definition for mangrove plants is a prerequisite to determining the species richness of mangroves in any geographical area. Trees and Shrubs of the Maldives 179 Adaptation Mangrove environment is highly dynamic and harsh and mangrove species are variously adapted to cope with these environmental conditions. species of true mangroves and mangrove associates in all the sites with different physiognomic aspects in each lagoon/estuary were identified and recorded separately. 2002; Wang et al. ‘mangrove species’ and ‘mangrove associates’ (see below). Indian Forester, 113: 214-. For references to fossil occurrences plants, animals, fungi, bacteria and other microorganism. This includes interpreting and providing guidance on the statutory language, providing oversight of local governments that have been delegated to implement the Present occurrences (first column) are after Gentry (1982) and Tomlinson (1986). Mangrove vegetation in six geographical regions of Kollam on the Southwest coast of India was selected to study the phytosociological characteristics and diversity indices. We hypothesized that the leaf litter decomposition rates of true mangroves differ significantly from the mangrove associates under the same ecological and bio-climatic conditions. There are 54 species of true mangroves (34 major and 20 minor) worldwide and 60 mangrove associates (Tomlinson, 1996).! As halophytes, they are physiologically adapted for either salt exclusion or excretion. From the study, 7 species of true mangroves, 4 species of semi-mangroves and 7 species of mangrove associates were identified in Vellikkeel. In Ezhome 10 true, 3 semi, 7 mangrove associates were identified respectively. The goal of this research is to provide high resolution local, regional, national and global estimates of annual mangrove forest area from 2000 through to 2012. Southeast Asia is a region of concern with mangrove deforestation rates between 3.58 percent and 8.08 percent during the analysis period, this in a region containing half of the entire global mangrove forest inventory.

Fossil record of common mangroves (m) and mangrove associates in the Cenozoic of the Gulf/Caribbean region. There have been significant changes in the traditional and present uses of resources within the mangrove system, which have implications on its depletion. In the present study, an attempt has been made to distinguish and separated the true mangroves from mangrove associates. These species are considered as mangrove associates. In the coastal regions, mangrove ecosystems host and influence biodiversity ranging from microbes to large fish and mammals. To achieve this we synthesize the Global Forest Change database, the Terrestrial Ecosystems of the World database, and the Mangrove Forests of the World database to extract mangrove forest cover at high spatial and temporal resolutions. UNU-INWEH. habitat are mangrove associates (Lugo and Snedekar, 1974; FAO, 2007). Mangroves provide many ecological, environmental and socioeconomic benefits to mankind. Mangroves are salt–tolerant forest ecosystems of tropical and subtropical intertidal regions of the world. considered as mangrove associates. Countries showing relatively high amounts of mangrove loss include Myanmar, Malaysia, Cambodia, Indonesia, and Guatemala. <> This review examines the recent investigations on the biological activities of extracts and chemicals identified from mangroves (mangroves, mangrove minors and mangal associates). Earthscan Publishers Ltd. Londo. The associates grow along with mangroves but lack typical characteristics. Globally, the IWP and the Atlantic, East Pacific (AEP) have different mangrove species groups (Hogarth, 2007; Spalding et al., 2010). 153. Marine Life in Hoi Ha Wan – Coral Communities .

This enhances a well developed mangrove ecosystem throughout the belt of costal area. on the environmental importance of mangroves and associates _____ Sacrificial leaf hypothesis of mangroves Background Extensive research into the halophytic nature of mangroves has led to as many myths about their physiology as there are documented facts. A detailed floristic account of the mangroves plants of Lothian Island Wildlife Sanctuary is presented based on the field study. The inter tidal vegetation is classified into three categories: 'Major mangroves,' 'Mangrove associates,' and 'Back mangal', on the basis of their morpho-anatomical characters representing adaptation to halophytic condition. The phytogeography of 35 exclusive mangrove species of Bay Islands distributed over 13 families and 17 genera is reported. Along the east coast, the least number of mangrove species is present in Tamil Nadu (Deshmukh and Mahalingam, 1991). Worldwide, 34 species or so in nine genera in five families are considered “true mangroves” and another 80 or so species occur as “minor components” and “mangrove associates.” True mangroves unprotected) ecosystems may be compared. Although few ecosystems are totally isolated from anthropogenic influence, those which remain largely unaffected serve as reference systems against which changes in intensively exploited or unmanaged (i.e. The parasitoids that emerged during the rearings were also collected.
