Cadmium-Induced Toxicity on Larvae of the Common Asian Toad Duttaphrynus Melanostictus (Schneider 1799): Evidence from Empirical Trials
This paper investigates the toxicity of cadmium (Cd) on young stages of the common Asian toad Duttaphrynus melanostictus (Schneider 1799). Signs of acute toxicity were evident in tadpoles repeatedlyExpand
Lethal and sub-lethal effects on the Asian common toad Duttaphrynus melanostictus from exposure to hexavalent chromium.
Chromium discharged in industrial effluents frequently occurs as an environmental pollutant, but the lethal and sub-lethal effects the heavy metal might cause in animals exposed to it have beenExpand
A new species of the pseudoscorpion genus Megachernes (Pseudoscorpiones: Chernetidae) associated with a threatened Sri Lankan rainforest rodent, with a review of host associations of Megachernes
Most species of the Old World pseudoscorpion genus Megachernes are associated with mammals, either within their nests or in their pelage, whereas others are found in cave systems, usually in batExpand
Effects of diazinon on larvae of the Asian common toad (Bufo melanostictus, Schneider 1799).
Continuous subchronic exposure experiments were conducted to assess the effects of diazinon, an organophosphate pesticide, on the survival, growth and activity of larvae of the Asian common toad BufoExpand
Impact of habitat disturbance on the distribution of endemic species of small mammals and birds in a tropical rain forest in Sri Lanka
We tested whether species endemic to Sri Lanka were less able than non-endemics to tolerate disturbed habitats. Small mammals were surveyed in four habitat types along a disturbance gradientExpand
Chlorpyrifos-induced Histopathological Alterations in Duttaphrynus melanostictus (Schneider 1799) Tadpoles: Evidence from Empirical Trials
This paper reports the histopathological responses of the gill, liver and tail muscle tissues in tadpoles of the Asian Common Toad Duttaphrynus melanostictus (Schneider, 1799) exposed to chlorpyrifosExpand
Distribution of five toxic heavy metals in biotic and abiotic constituents of the Negombo Lagoon, Sri Lanka
The presence of toxic metals in water has become a matter of national concern. This situation is potentially more dangerous when it occurs in lagoons and estuaries which are both highly productiveExpand
Habitat and dung preferences of scarab beetles of the subfamily Scarabaeinae: a case study in a tropical monsoon forest in Sri Lanka
We studied the food and habitat preferences of beetles of the subfamily Scarabaeinae in a protected tropical monsoon forest, theWasgomuwa National Park in Sri Lanka. While gaining an insight into theExpand
Toxic effects of Carbofuran on Duttaphrynus Melanostictus Larvae
This study investigated effects of the carbamate pesticide carbofuran on larvae of the Asian Common Toad Duttaphrynus melanostictus. Tadpoles were continuously exposed to four concentrations ofExpand
Chlorpyrifos-Induced Toxicity in Duttaphrynus melanostictus (Schneider 1799) Larvae
This study investigates the effects of continuous exposure to a widely used organophosphate pesticide, chlorpyrifos, on survival, growth, development, and activity of larvae of the Asian common toad,Expand
