Article
Ethnobiological knowledge is an important part of people's capacity to manage, conserve, and improve the governance of mangrove ecosystems. This paper assesses the ethnobiological importance of mangroves to coastal communities adjacent to seven mangrove forests in Southern and North-western Sri Lanka. 197 households were interviewed, and respondent...
Article
Understanding the extent of collaboration among stakeholders is key to supporting mangrove management. Despite the existence of robust policies, collaboration among stakeholders of mangrove co-management remains largely unexplored in Sri Lanka. This was partly due to the civil war, natural disasters, and other socio-economic changes over the past 3...
Article
Mangrove forests are reported to be invaded by invasive alien species (IAS). This study was therefore aimed at studying the level of distribution of the IAS, Acacia auriculiformis A. Cunn. ex Benth. in mangrove ecosystems in the southern coast of Sri Lanka and assessing the risk to periphery of mangrove forest by considering the Rekawa mangrove for...
Article
1. Among the several threats to the conservation of mangrove ecosystems in most South Asian countries, shrimp farming is predominant. Since the introduction of shrimp farming in Sri Lanka in the 1980s, mangroves on the island’s north-western coast have been continually cleared to create new shrimp farms, leading to a decline in the social-ecologica...

Article
The sustainable management of complex social-ecological systems (SES) typically requires coordination and collaboration between various groups of stakeholders. Yet, research on collaborative stakeholder networks and their linkages with sustainable mangrove management strategies is lacking in Sri Lanka. This study presents a social network analysis...

Protecting existing mangrove forests is a priority for global conservation because of the wide range of services that these coastal forests provide to humankind. Despite the recent reduction in global rates of mangrove loss, high historical loss rates mean that there are at least 800,000 ha globally that are potentially suitable for mangrove re-est...

The Negombo lagoon is one of the coastal lagoons in an urbanized city in the Northwestern province of Sri Lanka. The lagoon is heavily surrounded by human settlements, farms, aquaculture, and hospitals, which exposes it to sewage pollution. Locating and assessing the effluent discharge points into the lagoon is very important to know the ecological...

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...

Seed dormancy is a phenomenon that prevents an undamaged viable seed from germinating under favourable conditions. Various techniques have been applied to break dormancy in many weed-seeds based studies. The present study aimed to seek the most appropriate dormancy breaking method for six selected common weed species namely Cardamine hirsute (walab...

Mangrove forests provide key ecological processes which support the livelihoods of local communities and beyond, through the provision of a diverse set of ecosystem goods and services (Dahdouh-Guebas et al., 2021). In recent years, mangroves in Northern Sri Lanka have been exposed to increasing anthropogenic stressors that led to their degradation...

This study aimed to assess the heavy metal (HM) profile of the main upland tributaries of three major rivers, the Mahaweli, the Deduru and the Gin Rivers, which are commonly used for urban water supply in Sri Lanka. The HM profiles of arsenic (As), cadmium (Cd), lead (Pb) and mercury (Hg) were investigated by ICP-MS. Land-use classification was per...

The continuous increase in synthetic plastic production, combined with poor plastic waste management, has resulted in an increased dumping of plastics into our aqueous environment. As a result, microplastics, which are defined as plastic particles of less than 5 mm in size, are produced and persist in both seawater and freshwater environments. Micr...

Many coastal lagoons suffer multiple pressures from human activities that threaten their biological and ecological functionality. More specifically, heavy metal (HM) pollution has become one of the top threats that reduces sediment and water quality of coastal lagoons. Over the past decades, many scientific approaches have been made to reduce the...

Mangroves, the tidal forests serve numerous ecological services and economic benefits for the well-being of the coastal communities. Hence, they are known as resourceful ecosystems and can be used effectively for new advancements in science. Many research have been conducted in the fields of mangrove ecology, anatomy, floral biology, reproduction e...
Article
Sri Lanka is at the forefront of global mangrove conservation. It is the first country to officially protect all its remaining mangrove forests and has embarked on an ambitious plan to restore 10,000 ha of wetland during the United Nations Decade of Ecosystem Restoration. One incentive for this conservation effort is a recognition, based on researc...

Spatio-temporal changes during the last twelve year period (2006–2017) and their impacts on ecological and socio-economic status of Dondra lagoon, southern coast of Sri Lanka were studied as many lagoons in southern Sri Lanka are being seriously affected due to anthropogenic pressure in the recent past. The changes of Dondra lagoon and its immediat...
Article
Young plants of Rhizophora mucronata Lam. were tested for oxidative stress, photosynthetic capacity and dry matter accumulation under two abiotic stress conditions; prolonged submergence and soil water stress. The experiment of prolonged submergence was performed in field conditions with two treatment levels; 50% inundation (control) and 100% inund...

ABSTRACT The increase of freshwater inflow to Kalametiya lagoon, Sri Lanka, as a result of Udawalawe irrigation project that came into operation in 1967, has caused heavy siltation and reduction of salinity in the lagoon. The present investigation attempted to study and convey the current situation of Kalametiya lagoon and its future trajectory in...

The behaviour of carbohydrate metabolism in a plant, particularly its total starch content, total soluble sugar (TSS) content and their utilisation, is of great importance in coping with abiotic stress conditions. With this in mind, we studied total starch and TSS contents, survival, growth, biomass accumulation and stomatal conductance in Rhizopho...

Six wide-ranging mangrove species, Rhizophora apiculata, R. mucronata, Avicennia marina, A. officinalis, Bruguiera gymnorrhiza, and B. sexangula, were selected to study the growth and survival of seedlings under three contrasting salinity treatments over a 30-week period: low (3-5psu), moderate (15-17psu) and high (33-36psu). Seedlings grown under...

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...

Mangrove trees form unique forest at the edge of the land and sea. Amongst mangrove trees, the genus Avicennia L. stands out by successive cambia i.e. having not one cambial layer but subsequent active cambia and the organization of successive cambia seems to be very complex in three dimensional aspects and even in transverse sections. Further, sec...
