Four species of frogs, Common Skittering Frog, Tiger Frog, Indian Burrowing Frog and Indian Cricket Frog, and two toad species, Marbled Toad and Common Asian Toad were recorded. On the basis of present study, it is concluded that the permanent habitat alternation, destruction of habitat, use of indiscriminate toxic material such as pesticides, chemical fertilizers and increase of human population, three species Hoplobatrachus tigerinus, Tomopterna breviceps and Limnonectes limnocharis are declined and rated as threatened species in Thatta district, while two species Hoplobatrachus tigerinus and Tomopterna breviceps were rated as rare in Karachi district. The research techniques and information are helpful for graduate and research students of wildlife, National Parks managers, wildlife biologists, wildlife conservation organizations etc. …

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Pesticides have harmful effects on biodiversity. The present study was included the induced effects of permethrin and Biosal, against Agama lizard. It was observed that at the dose of 0.1% and 1% permethrin treated lizards, a total reduction in protein contents was found to be 42, 53% in kidney and 7.4, 10% in liver respectively. In the case of Biosal, animals were treated with 25 and 50% concentration and 0.36, 3.56% in kidney and 1.68, 2.2% in liver, protein content reduction was observed respectively, as compared to the control. The cholinesterase was found to be inhibited by 17, 19% in kidney and 18, 24% in liver, respectively, when the animals were treated with permethrin at aforesaid doses. In the case of biosal, inhibition of cholinesterase was found as13.6, 18% in kidney and 39.52, 56.21% in liver, respectively. The permethrin and biosal are toxic to lizards. It is therefore, suggested that biosal could be a better pesticide if used at lower doses as compared to permethrin.

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - The decline of amphibian population is a major environmental issue. Pollution in the aquatic ecosystem by pesticides is considered critical in the conservation of biodiversity. Several studies have reported the toxicological issues and adverse effects of pesticides in aquatic environment and biodiversity. The indiscriminate use of pesticides is considered one of the important factors that change the environment by causing imbalances in the ecosystem, especially in biota of the aquatic system. The present study was done to investigate the effects of two selected pesticide group organophosphate (Sandaphos, Chlorpyrifos) and pyrethroid ( -Cypermethrin and Dathrin) on enzyme cholinesterase and alkaline phosphatase in the liver, kidney and brain tissues of skittering frog Euphlyctis cyanophlyctis. It was observed that under the effects of Sandaphos, Chlorpyrifos, - Cypermethrin and Dathrin the enzyme activities were found to be significantly inhibited in liver, kidney and brain tissues of treated frogs. The research techniques and results are helpful for graduate and research students of Biological Sciences, Environmental Science and wetland managers.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - In the present study, the effects of environmental pollution on aquatic vertebrates of two Ramsar Sites viz. Haleji and Keenjhar Lakes were noted and inventories of the vertebrate fauna were prepared. In the water samples taken from Haleji Lake, the pesticides of organophosphate (OP) and organochlorine (OC) groups were estimated above the Maximum Acceptable Concentrations (MAC). These concentrations were much higher in muscles and fat contents than other tissues of birds. All water samples from Keenjhar Lake contained pesticides below the MAC level. A total of 22 species of mammals, 228 species of birds, 32 species of reptiles, 2 species of amphibia, 37 species of fishes and 33 species of plants were recorded from Haleji Lake, while, 25 species of mammals, 121 species of birds, 29 species of reptiles, 2 species of amphibia, 54 species of fishes and 258 floral species were recorded from the Keenjhar Lake. The research techniques and information are helpful for graduate and research students of Biological Sciences, Environment Science and wetlands managers.…
