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...

Mangrove restoration has been prioritized overall the world. Nevertheless, the restoration attempts show higher failure rates in many areas in the world. Therefore, the objective of this research was to study the impact of two common stress factors, physical drought i.e. water deficiency in soil and physiological drought i.e. difficulty in absorbin...

Sri Lanka is one of the global biodiversity hotspots but the biodiversity of the country is highly affected by various factors. Based on the preliminary observations, Acacia auriculiformis has invaded in Rekawa lagoon region (06º03´N–80º50´E). Therefore, the main objective was to study the distribution and the abundance of A. auriculiformis at the...

Exacum trinervium (Gentianaceae) in Sri Lanka received a lot of attention in recent years because of its endemism, national conservation status and medicinal & ornamental values. Therefore several groups of scientists in Sri Lanka have attempted to introduce E. trinervium as an ornamental plant through ex-situ cultivation. However, the production o...

Early life of viviparous mangroves merely depends on the propagule and it can be assumed that the period and the degree of dependency could depend on the size and the intrinsic factors of the propagule as well as on the edaphic and environmental factors in which the seedlings are growing. However scientific studies on the propagule dependency of ma...

A method to measure the salt secretion by mangroves which are open to the sea spray was developed and used to measure the salt secretion by mangrove species of Rekawa lagoon, an ecosystem with the highest diversity of true mangroves in southern Sri Lanka. Out of the twelve species of mangroves, only four species i.e. Acanthus ilicifolius, Aegiceras...
