Heavy metal contamination may have adverse effects on wetland biota, particularly amphibians. Severe immunotoxic elicited in Euphlyctis hexadactylus (Indian green frog) because of exposure (Cd, Cr, Cu, Pb, and Zn) the Bellanwila-Attidiya Sanctuary, a polluted urban Sri Lanka, provided rationale for present study. We evaluated biochemical histopathological this with reference E. population laboratory group that was subjected to 28 d mixture Cd, Zn (5 ppm each mixture). A scoring...
As in many other parts of the world, urban areas South Asian region are increasingly expanding. While cities today heart commercial, technological and social development, they also vulnerable to a variety natural anthropogenic threats. The complex infrastructure, ever-expanding population cities, exacerbate impacts climate change increase risk hazards. Throughout history, various hydrological disasters including floods, tidal surges, droughts, non-hydrological such as earthquakes,...
South Asian countries face a disproportionate impact from disasters due to their unique topography, poverty, low literacy rates, and socio-economic status. Human activities, such as unplanned urbanization poorly designed rural road networks, have further contributed in the region. The article explores potential of nature-based solutions (NbS) means addressing these challenges through integration green, blue, grey infrastructure. analysis evaluates significance NbS examines policies regional...
Semi-terrestrial tadpoles of the Sri Lankan dicroglossid rock frog (Nannophrys ceylonensis) feed by scraping surface microfilm from wet rocks on which they live. Gut content analysis 40 revealed microflora, microfauna, detritus, and mineral particles. Conspecific eggs were rarely also found in tadpoles' guts. Absolute gut length decreased 59% between Gosner stages 26 42, number coils as well. Tadpoles N. ceylonensis shift primarily herbivory to carnivory develop, with greatest occurring 32...
Fernando, E.; Wickramasinghe, D., and V.K., 2022. An overview of vertebrate faunal diversity in Sri Lankan mangroves. Journal Coastal Research, 38(2), 429–448. Coconut Creek (Florida), ISSN 0749-0208. Lanka is rich floral communities. The mangrove forests found within the island are particularly important, being crucial habitats for endemic globally threatened vertebrates. However, a comprehensive island's vertebrates known to utilise has not yet been studied. This review uses available...
Studies on Harmful Algae (HA) are rare in the Indian Ocean around Sri Lanka. The current study investigated diatoms and dinoflagellates five Lankan Southern coast locations, focusing potentially harmful species. A total of twenty-seven diatom species ten dinoflagellate were identified during study. Among them, eight (Asterionellopsis glacialis, Chaetoceros curvisetus, lorenzianus, Guinardia flaccida, Leptocylindrus minimus, Nitzschia sp., Proboscia alata Pseudonitzschia fraudulenta) three...
This research contributes to the current debate on linking flood events and developmental pressure in urban areas. Colombo District has faced frequent during last two decades which disrupted socio-economic environmental setup. district is economic hub administrative capital of Sri Lanka it area with highest population density country. It experienced rapid urbanization Land Use Cover Changes (LULC) recent past. The new infrastructure project developments, expansion impervious spaces,...
This study introduces GAUSS (Guided encoder-decoder Architecture for hyperspectral Unmixing with Spatial Smoothness), a novel autoencoder-based architecture unmixing (HU). consists of an Approximation Network (AN), (UN), and Mixing (MN). The AN incorporates spatial context within pixel’s neighborhood, while the UN utilizes pseudo-ground truth mechanism to enhance abundance estimation. MN provides estimated endmembers’ signatures. By incorporating UN-produced abundances, unlike conventional...
