Tropical lagoon ecosystems constituting lagoons with fringe mangroves are continually polluted with effluents from different sources. This study assessed the spatial variation of selected physicochemical parameters (pH, nitrates, phosphates, and conductivity) in water and sediments from the Chilaw lagoon and its fringe mangroves located on the Nort...
As a tropical island nation, Sri Lanka has a 1740 km coastal strip, dominated by mangroves, salt marshes and seagrass meadows i.e., blue carbon ecosystems, that play a vital role in ecosystem functioning and services. These ecosystems have a high capacity for storing carbon within their ecosystem pools by capturing atmospheric carbon dioxide (CO2)...
Lichenology has received much attention in recent decades due to two major reasons; functioning as bio-indicators and having chemicals with industrial significance. However, Manglicolous lichens (i.e., mangroves lichens) have not yet been extensively studied compared to other terrestrial lichens, particularly in Sri Lanka. Hence, this study was aim...
Carbon that is stored and sequestered in marine coastal ecosystems, such as mangroves, salt marshes and seagrass meadows is termed as Blue Carbon, which plays an important role in the global carbon cycle and climate change mitigation. It has long been known that mangroves which are confined to tropical and subtropical latitudes, have higher rates o...
Walawe river, which is located in Ambalantota, belonging to dry zone of Sri Lanka is highly exploited for domestic and irrigation purposes. Seawater intrusion in the river adversely affect the livelihood of bordering communities by hindering freshwater availability and salinization of agricultural lands. Present study determined the level of salini...
As the COVID‐19 pandemic continues to affect societies across the world, the ongoing economic and social disruptions are likely to present fundamental challenges for current and future biodiversity conservation. We review the literature for outcomes of past major societal, political, economic and zoonotic perturbations on biodiversity conservation,...
Managing the footprint of highly mobile fishing fleets is increasingly important due to continuing declines in fish populations. However, social‐ecological drivers for fisher behaviour remain poorly understood for many fleets globally. Using the Sri Lankan fleet as a case study, we explored the role of social, environmental and policy drivers of ef...
Amongst the several mangrove forests present in Sri Lanka, those in the Puttalam district have suffered the highest level of degradation arising from human activities, particularly shrimp farming. The occurrence and spread of the White Spot Disease (WSD) on shrimps both in shrimp farms and natural waters of Sri Lanka during 1994-1995 caused the aba...

Species-specific bans are increasingly being implemented to stem loss of vulnerable marine species, but there is a paucity of evaluative research into resulting socioeconomic and ecological consequences. In 2012, a blanket ban on landing Alopiidae (thresher) sharks was introduced in Sri Lanka. We used fisher perceptions, shown to influence support...

Project (1)
This project aims to improve the understanding of the socio-economic context within which elasmobranch fisheries exist in Sri Lanka and India and key drivers for behavior change. It aims to identify how fisher perceptions and values interact with socio-economic and ecological changes with a view to improving the effectiveness of governance and management. The project will utilize a mixed-methods approach and a wide range of methods to build a community-based narrative of fisherfolk livelihoods.
