After the 30-year long civil war was over, the Government of Sri Lanka commenced an accelerated programme to develop the Northern Province. If not carefully planned, such a programme will result in the loss of biodiversity and the consequent loss of services that ecosystems provide humans. Therefore, documenting the biodiversity found within coasta...

Sri Lanka’s location, historic and geologic isolation from the continental landmass, topography and climate act to shape its biogeography and biodiversity, including conferring a remarkably high level of endemism, given its close proximity to the mainland. The island hosts several ‘point endemic1 species and even monotypic endemic genera. However t...

Global climate action plans risk resulting to climate maladaptation and shocks when prudent measures are inapt. Adaptation strategies require multidisciplinary approach from all sectors with periodic monitoring and evaluation which are carefully planned, locally adaptable and results-oriented. For decades, various governments, development practitio...

After the three decade-long civil war was over, the Government of Sri Lanka commenced an accelerated programme to develop the Northern Province. If not properly planned, these developmental projects will result in the loss of biological diversity and, in particular, the consequent loss of services that ecosystems provide humans. One of the importan...

The abundance of microplastics (MPs) in surface water and beach sediment in Southern Sri Lanka covering a distance of 91 km of coastline is reported. MPs were classified according to polymer type, geometry and color of the sites tested 60% showed MP contamination in sand and 70% in surface waters off the coast. The size range of MPs from surface wa...

Marine Alien Invasive Species (AIS) have been proliferating in marine landscapes as consequences of ballast water discharge, pollution, eutrophication, and climate change. In Sri Lanka, AIS records in marine waters are almost zero compared to terrestrial habitats. Their distribution, abundance and the magnitude of the impact on the ecosystem, its f...

Near shore patchy reef located at the leeward side of the fringing reef at Polhena was surveyed to evaluate spatial patterns of growth rates of Pocillopora damicornis . This study was carried out at three locations of the reef; front, side and back from June to November in 2004. Three sites were selected from each location considering the depth (su...

Dolphin and whale watching has become a blooming activity in the tourism industry in Sri Lanka. Proper scientific data is lacking for the understanding and management of dolphin and whale watching activities particularly in the Southern coast. Based from Mirissa, a shipboard survey was conducted for 43 days from January to May 2012 covering 940 km2...

The coastal zones of South Asia’s five coastal countries (Bangladesh, India, the Maldives, Pakistan, and SriLanka) contain 22.5 percent of the global population and about 40 percent of the economic activities in the region. This region is extraordinarily rich in ecological diversity (Loiczsouthasia.org/southasiacoast.php). This ecological richness...

Seagrass is the only angiosperm that existed in shallow marine environments. They are one of the vital ecosystems which act as a foraging ground of dugong, sea turtles and nesting and feeding ground of various type of fish. Seagrass meadows enhance the water quality of the coastal environment by trapping the sediments of the water and it ensures th...

Consisting of more than 32,000 species, marine fish are the most diverse group of organisms among the chordates (Froese & Pauly, 2012). They are found in most bodies of water and found in nearly all aquatic environments, from high mountain streams to the abyssal and even hadal depths of the deepest oceans. Depending on the oceanic zone they occupy,...

Coral reefs occur along only 2% of the 1585 km coastline of Sri Lanka. Large extents of these reefs are subjected to numerous anthropogenic impacts, with some reefs showing considerable damage by a single activity that is dominant in the area, frequently well rooted in the local community and contributing significantly to the local economy. This st...
