Experiment code 16.5.3.18
Experiment Title Exploration and evaluations of mangrove diversity along coastal belt of South Gujarat.
Research Type Departmental Research
Experiment Background • Mangroves are extraordinary ecosystems, located at the interface of land and sea in tropical regions, which offer a considerable array of ecosystem goods and services. • Although they are found in 123 nations and territories, mangrove forests are globally rare. They represent less than 1% of all tropical forests worldwide, and less than 0.4% of the total global forest estate. • Mangroves are disappearing three to five times faster than overall global forest losses, with serious ecological and socio-economic impacts. • These forested wetlands are rich in biodiversity. They support complex communities, where thousands of other species interact. They provide a valuable nursery habitat for fish and crustaceans; a food source for monkeys, deer, birds, even kangaroos; and a source of nectar for honeybees. • Managing and restoring mangrove ecosystems is an achievable and cost effective way to help ensure food security for many coastal communities. • Mangrove ecosystems are highly effective carbon sinks, sequestering vast amounts of carbon within the soil, leaves, branches, roots, etc. • One hectare of mangrove can store 3,754 tons of carbon; it’s the equivalent of taking 2,650+ cars off the road for one year. • If destroyed, degraded or lost these coastal ecosystems become sources of carbon dioxide. Experts estimate that carbon emissions from mangrove deforestation account for up to 10% of emissions from deforestation globally, despite covering just 0.7% of land coverage. • The review shows that Indian mangroves consist of 46 true mangrove species belonging to 14 families and 22 genera, which includes 42 species and 4 natural hybrids. • The mangrove forests of the State of Gujarat are represented by 15 mangrove species • Among these 15 species, A. marina is the most dominant species. In fact, it represents about 97% of the total mangrove cover of the State. Even though Kachchh has the highest mangrove cover, the highest floristic diversity of mangroves has been reported from South Gujarat region owing to better fresh water inflow. In fact, many mangrove species are found only in South Gujarat region.

Experimental detail

:
  • Sampling site: Costal belt of South Gujarat.
  • Sample collection time: Throughout the year  
  • Design: Survey with belt transact
  • Molecular work : Forest Biotechnology Laboratory/ Environment Science Lab, College of Forestry, ASPEE College  of Horticulture  and Forestry, Navsari

Methodology:

  • Photographs and GPS locations of the mangrove species will be recorded from the costal belt of the South Gujarat
  • Morphological observation will be recorded from the each  species.
  • Leaf samples will be collected for the reported mangrove species and will be stored under -20 0C as per standard collection procedure
  • DNA extraction will be carried out from the leaf samples of respective species of mangroves through CTAB method.
  • DNA will be subjected for quality and quantity check on agarose gel electrophoresis analysis and Nanodrop specrophotometric analysis.
  • Cytoplasmic (Mitochondrial/Chloroplast) set of the markers or nuclear (Dominant/Co-dominant) set of the markers will be used to study the molecular variation present among the species as well as between the haplotypes.
  • Documentation of report will be in form of  number of species reported, morphological characters of the species and molecular variation in form of dengrogram/heat map/diversity index etc.
