The present investigation was carried on the diversity and distribution of mangroves in Kumbalam Island of Ernakulam district to study the present status of mangrove vegetation. Table 1. another 80 or so species occur as “minor components” and “mangrove associates.” True mangroves are ecologically restricted to tidal swamps and form extensive monospecific stands. pp 1, classification of Indian mangroves: a revie, Mo E F. 1987. There may be no other group of plants with such highly developed morphological and physiological adaptations to extreme conditions. Natural regeneration in underutilized lands in backwater systems, afforestation programmes, conservation initiatives and growing awareness on the mangrove ecosystems have highlighted the need to conserve and manage them sustainably. 20 minor) worldwide and 60 mangrove associates (Tomlinson, 1996).!

Adaptation. 4 0 obj The three species which have the highest density, The mangrove periwinkle lives above the waterline on the prop roots of the red mangrove. Globally, the IWP and the Atlantic, East Pacific (AEP) have different mangrove species groups (Hogarth, 2007; Spalding et al., 2010). Phytochemistry and phytochemical responses. Species of mangrove associates comprise 30 trees, 24 shrubs, 18 herbs, 6 climbers, 4 grasses and 4 epiphytes (Kathiresan et al., 2009). In order to study the distribution pattern of mangrove species, Quadrat analysis was adopted in the study site. A mangrove is a shrub or small tree that grows in coastal saline or brackish water. The m. 2014). These species are considered as mangrove associates. 1999. There are problems that the mangrove ecosystems faced such as habitat … reported 60 species mangrove associates belonging to 46 genera and 27 families that exist in the world mangroves. Occurrence of 28 mangrove species and 11 floral associates were found, which identifies the entire bay as one of the most diverse mangrove forests in the country.

Mangroves are the plants adapted to strident environment with unvarying inundation of the soil and extremely diverse salinities, habitual in river banks, sand flats and coastlines of the tropics and subtropics of the world. The bottom row indicates: mangroves are more affected than mangrove associates in relation to disturbances (a), disturbance increases biological invasion (b), with increasing invasion, propagule availability of mangrove species drops sharply but little effects on mangrove-associate species (c) and with increasing invasive-barrier, occupancy of mangrove-associate species increases (d). Total number of species of flora and fauna reported in mangrove ecosystems of India (Kathiresan & Qasim, 2005) No. Mangrove species are broadly classified as ‘true mangroves’ and ‘mangrove associates’. Mangroves play an important role in buffering coastlines against storm surges and tsunamis through wave attenuation (Kathiresan and Rajendran, 2005, Wolanski, 2007, Barbier et al., 2008, Teh et al., 2009).Studies have shown that the flooded area produced by Hurricane Wilma in … 2002; Wang et al. considered as mangrove associates. This approach reveals the existence of multiple. Adaptation. The mangals of South Andaman Island were surveyed for the insect fauna of mangrove associates. According to the estimate of this study, the extent of mangroves of Kerala is 2502 ha out of which 1189 ha belongs to the state but 1313 ha is under private ownership.

Totally, 12 species of mangroves belonging to 8 genera and 6 families were identified; Rhizophoraceae and Avicenniaceae were the most dominant group represented. The possible effects of erroneous mangrove species lists are discussed in the contexts of biogeog-raphy, remote sensing and biological conservation. %PDF-1.5 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.

From the study, 7 species of true mangroves, 4 species of semi-mangroves and 7 species of mangrove associates were identified in Vellikkeel. Shannon-Weiner Index of diversity ranged from 2.002 to 3.11; species richness from 0.429 to 1.033 and the similarity in floral composition varied from 0.33 to 0.66. Most of the mangroves of Sri Lanka belongs to … groves, 6 mangrove associates and 10 controversial species). Abstract . have been made to discover new antimicrobial of mangroves and mangrove associates are widely used compounds from many kinds of natural sources such as throughout the world [3]. In the present investigation, the diversity and distribution of mangrove vegetation were studied since 2010. Distribution status of these species has been measured using A/F ratio. The back mangrove is home to several mangrove tree and Listing under Modern only (second column) means there are no fossils reported from the region. The associates grow along with mangroves but lack typical characteristics. Vector control using phyto-chemicals is one among the mandates of our study. We provide a standardized global spatial dataset that monitors mangrove deforestation globally at high spatiotemporal resolutions, covering 99 percent of all mangrove forests. In mangrove estuaries they can be found clinging to the prop roots or trunk of red mangroves.

True mangrove species are those that strictly grow in the mangrove environment while associated species may The Godavari Delta, like many other deltaic systems in India, has been highly altered by human activity [32]. Global mangrove deforestation continues but at a much reduced rate of between 0.16 percent and 0.39 percent annually. The relative mangrove diversity (HMD) of each of the 12 habitats is calculated as, RMD=100 × [(Fn+Gn+Sn)/N], where Fn, Gn and Sn are respectively, numbers of families, genera and species, and N = 170 (sum of numbers of families, genera and species in mangrove vegetation of all the 12 habitats in India).
