A study on Punjab urial (Ovis vignei punjabiensis) was conducted in Soan valley during June 2011 to find out its distribution, population status and potential threats. Five potential sites namely: Dadder, Khabeki, Chambel, Kund and Uchali Forests were selected. The study conducted was based on Sample Count Technique, Line Transects and Point Counts methods as well as discussion with officials of Punjab Wildlife and Parks Department, representatives of local communities and local hunters. The occurrence of urial was confirmed at four out of five study sites. Using 17 transects and eight point surveys, 28% of the total area was sampled and 110 animals were estimated with a population density of 1.39 animals/km2. Male to female ratio was 1:1 while lamb to adult female ratio was 0.35:1. Questionnaire survey based on interviews of local residents including agriculturists, farmers, shepherds, livestock farmers, wildlife & forest officials, and local hunters was conducted for an assessment of the species occurrence and potential threats to the species. Signs such as fresh tracks, droppings and body parts including hair entangled with bushes, horns and other dead remains of the animal, as a result of natural or accidental deaths, were used as indication of the species presence in the study area. Habitat degradation due to increased developmental activities, poaching of lambs by local hunters, predation of lambs by continuously increasing population of jackals, illegal hunting due to weak enforcement of wildlife laws, intentional forest fire by local people to obtain firewood, food competition with livestock and transmission of various diseases from livestock to urial population were found as main threats to this species. © 2015, Pakistan Agricultural Scientists Forum.

We present the study results of the effectiveness of in-burrow rodenticide bait delivery method for controlling small rodents infesting groundnut fields of Pothwar region of Pakistan. Species of economic importance associated with the crop were: Bandicota bengalensis, Nesokia indica and Tatera indica. Formulated baits of zinc phosphide (2%) wax cake and broken rice; brodifacoum (0.005%) wax block and coumatetralyl (0.0375%) broken rice were subjected to evaluation. The baiting was initiated at the start of peg formation and stopped one week before harvesting the crop. After five bait applications the results indicated varied degrees of reduction in the burrow activities. These were reduced by 100, 48.3, 74.4 and 62.7% with the usage of baits of brodifacoum (0.005%), coumatetralyl (0.0375%) and zinc phosphide (2% wax cake and broken rice), respectively. However, the estimated mortality showed that all the bait formulations were equally effective i.e. ranging between 95 to 100 %. The study results suggest that 4 to 5 applications of the rodenticide baits are sufficient to obtain economic yields of groundnut crop. © 2012 Zoological Society of Pakistan. Source

Uptake of hexavalent chromium (Cr VI) using dead biomass of green algae, Spirogyra spp. to evaluate biosorption capacity with special emphasis on its mechanistic aspect was studied. Optimum biosorption of Cr (VI) was observed at pH 4.0 (265mg/g), biomass concentration of 1mg/g, and temperature 303K.Various adsorption isotherms were employed to analyze the experimental data of which Langmuir isotherm was found most suitable, showing monolayer adsorption. Pseudo-second order model was found suitable for the kinetic interpretation of the data. Various thermodynamic parameters were calculated and the biosorption was found to be spontaneous, endothermic and feasible under the given conditions. Analysis of FTIR spectra indicated the presence and role of electronegative functional groups on algal surface responsible for binding of Cr (VI) ion. Source

As part of the Sino-Pak trans-boundary cooperation for conservation and sustainable development in Pamir border region, World Wild Fund (WWF)-Pakistan conducted a preliminary social, economic and ecological survey in the Shimshal-Pamir Lakes area in July 2009. The purpose of the study was to explore potentials and opportunities for future collaborative conservation of some species, habitats and high altitude ecosystems in the border region between China and Pakistan. The two-week herpetological study in the Shimshal Pamir area of Khunjerab National Park (KNP) along Pakistan-China border was an integral part of the survey, conducted exclusively to document reptilian fauna with a special emphasis on investigating their occurrence, distribution and status in the study area. Field investigations were performed during daytime when it was hot enough and reptiles were active, basking or feeding. A total of 15 specimens belonging to four species of the Agamidae family were captured by striking stones and beating bushes with sticks. Collected specimens were preserved using 10% formalin solution, tagged with field information and stored in Zoological Survey Department, Karachi for future reference. Laboratory investigations were carried out for pholidosic counts and morphometric measurements. A detailed review of relevant literature, habitat characteristics and laboratory investigations revealed the occurrence of Laudakia himalayana, L. pakistanica, L. tuberculata and L. badakhshana at 4,082 m, 4,172 m, 4,005 m and 4,240 m asl, respectively, which are much higher altitudes as compared to the previously reported heights of 3,353 m, 3,200 m, 2,500 m and 2,400 m asl. The terrain offers a variety of ecological barriers, in the form of fast and freezing running waters and massive glaciers with peculiar harsh climatic conditions prevailing for nine months of the year, which restricts species migration and thus increases endemism. Although one of the four species recorded from the study area, i.e. L. pakistanica is endemic to Pakistan, L. tuberculata and L. badakhshana are new records from Shimshal, Pakistan, so a detailed investigation is suggested for further herpetological records from the study area.

A 2-week long avian survey in Shimshal valley in Khunjerab National Park was conducted during July 2009 to establish the baseline about the existence, distribution and current status of different bird species. All the potential habitats were visited and 48 avian species belonging to 9 orders and 24 families were recorded. While observing the avian species in the area, a flock of eight Tibetan larks (Melanocorypha maxima) was surprisingly observed which makes the first record of Tibetan lark not only in Shimshal valley but also in the country, thus extending the distribution range of the species further westwards along the Karakorum mountain ranges and adding to the avian fauna of the country.
