Cloud computing resources have many advantages for geoinformatics researchers: as many collaborative projects have participants who are widely dispersed, hosting data in the cloud and running analytical workloads on virtual machines makes it possible for all participants to work together equally. Equally, the ability to scale computing environments...

Cold-tolerant and cold-loving microorganisms are important components of ecosystems in cold area or under cold conditions. These microorganisms use specific mechanisms to withstand cold stress and to perform well under such stress conditions. These mechanisms, which are mainly dependent on a variety of enzymes, are crucial for various industries fr...

Next generation biofertilizers: Challenges and solutions

Although biofertilizers have been used for an exceptionally long time, challenges still remain in using them to phase out chemical fertilizers. Chemical fertilizers generate environmental pollution and negatively impact beneficial organisms as well as human and animal wellbeing, causing a paradigm shift towards safer improved biofertilizers. Hence,...

The rapid rate of industrialization has paved the path for green, smart, and organic products. In addition, the demand for agricultural products will grow heavily annually as the world's population is expected to reach around 9 billion in 2050. Organic food is commonly assumed to be more natural, an assumption that is among others based on its prod...

Cinnamomum zeylanicum is one of the oldest spices used for culinary purposes in Asian countries. Its extracts have demonstrated a positive impact on controlling the progression of disease pathologies due to antioxidant, anti-inflammatory, antimi-crobial, anticancer, anti-mutagenic, anti-tyrosinase and antidiabetic characteristics. C. zeylanicum als...

Brassica nigra plays an important role in global agriculture, horticulture, health and wellness aspects due to its culinary and medicinal values. B. nigra plant is also grown to obtain oil for industrial purposes as well as a nutritionally valued seed meal. The seed primarily contains oligosaccharides belonging to the raffinose family; amino acids;...

Aflatoxin B1 contamination adversely affects human health by impairing long-term physical and cognitive development. Several crops have been associated with aflatoxin B1 contamination and corn is one of them. In the Anuradhapura district of the North Central Province of Sri Lanka, corn is one of the main agricultural produce. Due to poor farming pr...

Nannophrys marmorata is a critically endangered species of frog known only from a few locations in the Knuckles Conservation Forest (KCF) in the Knuckles mountain range of Sri Lanka. Here, we report new localities outside its known range in the KCF and examine the distribution of N. marmorata providing the most extensive distribution map for this s...

Noncommunicable diseases (NCDs) are on the rise around the world, while this phenomenon is comparatively more prevalent in developing countries. It has been identified that this situation arose in developing countries owing to nutrition transitions and adaptation of a sedentary lifestyle, both of which are consequences of urbanization. While priori...

Ehirava fluviatilis is a marine origin clupeid found in Southern India and Sri Lanka, also found in two freshwater lakes, namely Parakarama Samudraya and Rajanaganaya reservoir, and that places are identified as secondarily colonizedhabitats. The objectives of this study were carried toinvestigate the fatty acid (FA) profile in the flesh of E.fluvi...

Background: Quantification of toxic trace metals in biota is very important to monitor both ecosystem health and public health. Stomopneustes variolaris is a widespread species of sea urchin in the world that have edible gonads that are in high demand. This study attempted to examine the levels of accumulated toxic trace metals and their relation-...

This study attempted to describe the length and weight frequency, and length-weight relationship in the black sea urchin, Stomopneustes variolaris, in Sri Lanka. The sampling sites Mount-Lavinia (n=43), Beruwala (n=99) and Tangalle (n=55) were selected from South-west coast in Sri Lanka. The shell length and body weight were measured separately for...

Diabetes is a global pandemic which warrants urgent attention due to its rising prevalence and economic burden. Thus, many alternative therapies are being researched for anti-diabetic properties, given the inefficacy of current medicinal treatments. From this perspective, Aronia melanocarpa or Black Chokeberry has been investigated for its therapeu...

Disease conditions for which administration/consumption of A. melanocarpa has proven to be effective.

Images of (A) A. melanocarpa in fields during summer-time (B), bushes with fruits, (C) fruits & leaves and (D) the chemical structures of some of the potent bioactive compounds present in A. melanocarpa.

Among the eight species of Eutropis Fitzinger currently known from Sri Lanka, Eutropis bibronii (Gray, 1838) is among the least known. Hence, the occurrence of this species in Sri Lanka has been doubted by some authors since there were no confirmed records from live specimens for the past 70 years. The species has been previously reported mostly fr...

The known distribution in Sri Lanka of the endemic freshwater crab Oziothelphusa mineriyaensis Bott, 1970 was limited to 2 known localities in the dry zone. In this study of the distribution of this species in the North Central Province of Sri Lanka, we identified 5 new localities. Our findings expand the extent of occurrence from 168 km2 to 1467 k...

The Sri Lankan traditional medicinal system reaches back over 3000 years. The traditional medicines of Sri Lanka have gained an impressive level of acceptance over their more ‘Western’ counterparts, despite the lack of substantial scientific evidence. This is due mainly to cultural, folklore, habitual use, and ethological reasoning. One well respec...

The Diplopoda have been studied for some 250 years, but until the later part of the nineteenth century most descriptions were rather cursory and neither the species concept nor type concept were well established (Hoffman 2009). Even for well-explored regions like Europe, the description of the Diplopoda saw a proliferation of synonyms (Enghoff 1976...

This Study was conducted in Kammalakkulama tank, a freshwater ecosystem and sampling was done twice per week. Random sampling, quadrate sampling, line transect, point count, dung counting, footprints counting and opportunistic observation methods were used to determine the diversity of vertebrate fauna and calculated Shannon-Weiner Diversity index...

Sea urchin samples (Stomopneustes variolaris) were collected from the selected (3 sampling locations) western and southern coastal area around the Sri Lanka (n=193) from the time period of May to October, 2014. Sampled animals were measured for biometrical parameters, dissected and separated roe tissues, which were analysed for the proximate compos...

This review lists the currently known species of millepedes in Sri Lanka and discusses their current taxonomic status and distribution based on previous studies from 1865 to date. A total of 104 millipede species belonging to 44 genera, 18 families and nine orders have been recorded in Sri Lanka. Of these, 82 are known only from Sri Lanka; addition...

Sea urchins belong to phylum Echinodermata; they are very important marine creatures in the world and widely distributed in all seas from Arctic to Antarctic regions. Consider the economic value of sea urchins, they are harvested for their gonads, which are a highly prized delicacy in some parts of Asia, Mediterranean and the Caribbean countries an...

Mihintale sanctuary is one of the important forest reserve located in Sri Lanka with scarce information on avifauna. Although this area has been subjected to anthropogenic activities, periphery areas provide more suitable habitats for different species of birds including migrants. Current study is carried from July 2010 to end of February 2012 in t...
