They dont extend into the terrestrial plant. However as for some fringe species found mainly on the landward transitional zones of mangroves no consensus among scientists could be reached in favor of this classification and much debate arises.
Aims Mangrove species are classified as true mangroves and mangrove associates.
True mangroves and mangrove associates. Mangrove species are broadly classified as true mangroves and mangrove associates. We hypothesized that the leaf litter decomposition rates of true mangroves differ significantly from the. Mangrove species are broadly classified as true mangroves and mangrove associates.
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. In order to test this hypothesis the leaf litter decay rates of 24 true mangrove species and 10 mangrove associates along with the concomitant carbon and nitrogen dynamics of the litters were studied in the tropical mangrove forest of Sundarban by means of litter bags. The present investigation which was carried out between the periods from September 2014 to July 2016 had recorded a total 29 true mangrove species and 72 associate species from various regions of.
Mangrove plants can be classified into two types. True mangroves and mangrove associates. True mangroves have developed at least one or more specialised physiological or morphological adaptations in order to survive in such stressful environment.
Mangrove associates is a group of plants growing between mangrove plants and the land but seldom immersed by normal tides. The habitats of mangrove. The true or exclusive mangroves are those that occur only in mangrove habitat Santisuk 1983Tomlinson 1986Duke 1992 andGiesen et al 2007 or only rarely elsewhere and the mangrove associates or non-exclusive mangroves are those which comprise a large number of species typically occurring on the landward margin of the mangal and often the non-mangal habitats such as rainforest.
Their list included both true mangroves and mangrove associates classifications by Tomlinson 1986 and Hogarth 2007. Tomlinson 1986 lists the criteria of true or. Mangrove flora can be categorized as true mangroves and mangrove associates.
True mangrove species grow only in mangrove environment and do not extend into terrestrial plant community whereas mangroves associates are found within or in the peripheral areas of mangrove wetlands. Mangrove flora can be categorized as true mangroves and mangrove associates. True mangrove species grow only in mangrove environment and do not extend into terrestrial plant community whereas mangroves associates are found within or in the peripheral areas of mangrove wetlands.
Leaf mass were lower than that of mangrove associates. Bhitarkanika has 33 true mangrove species and more than 40 mangrove associates whereas Mahanadi delta has 29 true mangrove species and more than 20 mangrove associates. The Devi Estuary has 19 true mangroves and more 17 mangrove associates while Chilika Lake has only 6 true mangrove species which were planted.
Actually there are two classifications of mangroves in the world. The true mangroves and the mangrove associates. True mangroves are woody plants.
They have a mechanism for waterlogged saline and anaerobic conditions. Their vegetation is morphologically physiologically and reproductively adapted to the mangrove environment. They dont extend into the terrestrial plant.
Mangrove associate plants were mostly found in all the sampling stations but mangrove plants were noted only in a few stations. A mangrove species Avicennia marina and four associates Thespesia populnea Sesuvium portulacastrum Calotropis gigantea and Citrullus colocynthis were reported in all five groups of study areas. True mangroves are true halophytes and mangrove associates are glycophytes with certain salt tolerance.
Salinity factor also limits the distribution of species per zones. All species are tabulated together with their suggested classification. Keywordshalophytes true mangroves mangroves associates glycophytes.
These places are far from one another and the mangrove species diversity varies from one place to another due to factors such as climate tidal factors and anthropogenic pressures. Nine true mangrove floral species belonging to six families and ten associated floral species belonging to nine families were identified along the inundated and the adjacent regions at the study sites. We have 44 true mangroves and 86 mangrove associate species that support 4060 animal species in Indian mangrove ecosystem.
Mangroves are coastal forests. The term mangrove originates from the Senegalese word mangue which means into the sea. Mangroves are halophytes ie.
The ecosystem of mangroves establishes and grows at. MANGROVE ASSOCIATE FLORAL SPECIES. A PROBABLE DEFINITIONThe floral species in mangrove ecosystem can be categorized into true mangroves and mangrove associates Selvam 2007Wang et al 2011.
The species which are adapted to mangrove habitat and do not extend into other terrestrial plant communities are referred to as true mangrove species. Aims Mangrove species are classified as true mangroves and mangrove associates. However as for some fringe species found mainly on the landward transitional zones of mangroves no consensus among scientists could be reached in favor of this classification and much debate arises.
