Title: Marine Biodiversity and Ecosystem Functioning

Project Leader:
Lokabharathi, P.A.

Vision:

To understand the complex interactions between organisms in the marine ecosystem in order to help conserve and protect biodiversity

Objectives:

  • To address the biodiversity of the coastal waters of Goa, west coast of India and the Lakshadweep islands
  • To understand the role of organisms at various levels (genes to species to larger groups) in the functioning of the two ecosystems
  • To evaluate the potential causes that will change the diversity
  • To develop models to predict changes in the diversity
  • Ex situ conservation of diversity and establishment of a taxonomy reference centre
  • Seasonal collection and monitoring of marine plants, animals and microorganisms from the coast of Goa, identification, standing crop estimations; preparation of databases and electronic atlases of the diversity along the west coast of India
  • Completion of protocols to study the quantitative and qualitative importance of different groups of organisms in ecosystem functioning (workshop on mesocosm experiments envisaged)
  • Characterization of genetic variations within 4 fish species
  • Resource management of coastal, estuarine ecosystem (scoping workshop withh CSIRO, Australia is envisaged

The importance of marine biodiversity:

  • The marine ecosystem provides mankind with food, medicines, industrial products and pleasure.
  • This ecosystem has to be maintained in a healthy state, if it is to provide us benefits in a sustained manner.
  • Natural, healthy ecosystems have evolved over periods of millions of years, resulting in complex interactions of the environment and all the species living in them.
  • Such interactions allow the optimal utilization of the ecosystem resources by a maximum number of species, that includes the human beings.
  • The waters along the west coast of India are biologically very productive and possess several unique environmental features. Numerous industries are also developing along this coast.
  • It is essential to scientifically understand the interactions between biodiversity and the environment in these waters, in order to conserve and protect the ecosystems.
