This report presents the occurrence of two species of crowned jellyfish, Cephea coerulea and Netrostoma setouchianum, recorded for the first time from waters off the coast of Pakistan in the northern Arabian Sea. Diagnosis of the genera Cephea and Netrostoma are provided. We also provide simple keys for the identification of cepheid genera. We found that long filaments on mouth arms in Cephea easily distinguish it from Netrostoma, which has no such filaments. © 2015 Check List and Authors.

Levels of total organic carbon (TOC) and black carbon (BC) were determined together with those of organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) in the selected eighteen coastal sites (n = 285) along the Arabian Sea from Pakistan. Results showed that the total concentration of TOC, BC, ∑OCPs and ∑26PCBs ranged between 0.3 and 2.9% dw, 0.1-0.2% dw, 0.9-110 ng g-1 dw and 6.2-1200 ng g-1 dw, respectively. Correlation analysis of BC (r = 0.26-0.89) and TOC (r = 0.06-0.69) revealed a stronger association with studied compounds. The sedimentary depositional fluxes (D) for ∑OCPs and ∑26PCBs were calculated as 1.7 and 4.9 tons yr-1, respectively. In the coastal belt of Pakistan, sedimentary mass inventories (I) indicated the presence of 13 and 37 metric tons of ∑OCPs and ∑26PCBs, respectively.©2014 Elsevier Ltd. All rights reserved.

Salkhala Game Reserve (SGR) in Azad Kashmir, Pakistan, lies within an Important Bird Area (IBA) of the Western Himalayas Endemic Bird Area. The conservation status of the reserve and its birds is poorly known due to political instability in the disputed territory of Kashmir and the relative remoteness of the site. The findings of a bird survey undertaken from May 2007 to April 2008 are documented here. In total, 101 species were recorded including 45 resident species, 48 breeding migrants and six winter migrants. There were significant records of the globally threatened Western Tragopan Tragopan melanocephalus, the Near Threatened Pallid Harrier Circus macrourus and European Roller Coracias garrulus, and the restricted-range Kashmir Nuthatch Sitta cashmirensis and Spectacled Finch Callacanthis burtoni. Kashmir Flycatcher Ficedula subrubra and Cheer Pheasant Catreus wallichi were not recorded in the IBA, with the latter species now possibly locally extirpated. An annotated checklist of the species recorded is presented along with measures of relative abundance. Habitat fragmentation, degradation and clearance through the collection of fuel and timber, forest fire, livestock grazing, collection of non-timber forest products and unsustainable use of pastures are the major threats to the wildlife of SGR. These conservation issues are discussed briefly along with recommendations for the future management of the reserve.

The present study was conducted to reveal the concentrations and patterns of organochlorines [i.e., organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs)] in freshwater fish species collected from four ecologically important sites of the Indus River i.e., Taunsa (TAU), Rahim Yar Khan (RYK), Guddu (GUD) and Sukkur (SUK). In the fish muscle tissues, concentrations of 15 OCPs (15OCPs) and 29 PCBs (29PCBs) varied between 1.93-61.9 and 0.81-44.2 ng/g wet weight (ww), respectively. Overall, the rank order of OCs was DDTs>PCBs>hexachlorocyclohexanes (HCHs)>chlordanes (CHLs). The patterns of PCBs showed maximum contribution of tri-CBs (59%). Ratios of individual HCH and DDT analytes contributing to the summed values indicated both recent and past use of these chemicals in the region, depending upon fish species. To assess the associated health risks, carcinogenic and non-carcinogenic risks were calculated through hazard ratios (HRs). For carcinogenic risk, HR was >1 at both 50th and 95th percentile concentrations, suggesting that the daily exposure to OCPs and PCBs yields a lifetime cancer risk of 1 in a million. HR for non-cancerous risk was <1 at both the percentiles, signifying no adverse effect by OCs exposure in native population.

Organochlorine pesticides (OCPs) were investigated in passive air and soil samples from the catchment area of the Indus River, Pakistan. 15OCPs ranged between 0.68 and 13.47 ng g(-1) in soil and 375.1-1975 pg m-(3) in air. HCHs and DDTs were more prevalent in soil and air compartments. Composition profile indicated that -HCH and p,p-DDE were the dominant of all metabolites among HCHs and DDTs respectively. Moreover, fBC and fTOC were assessed and evaluated their potential role in the distribution status of OCPs. The fTOC and fBC ranged between 0.77 and 2.43 and 0.04-0.30% respectively in soil. Regression analysis showed the strong influence of fBC than fTOC on the distribution of OCPs in the Indus River catchment area soil. Equilibrium status was observed for -HCH, -HCH, p,p-DDD, o,p-DDT, TC, HCB and Heptachlor with ff ranged between 0.3 and 0.59 while assessing the soil-air exchange of OCPs.

This study was conducted with the aim of assessing the levels and black carbon mediated sediment-water partitioning of organochlorine pesticides (OCPs) from the Indus River. OCPs ranged between 52-285 ng L(-1) and 5.6-29.2 ng g(-1) in water and sediment samples respectively. However, the ranges of sedimentary fraction of total organic carbon (f(TOC)) and black carbon (f(BC)) were 0.82-2.26% and 0.04-0.5% respectively. Spatially, OCPs concentrations were higher at upstream sites as compared to downstream sites. Source diagnostic ratios indicated the technical usage of HCH (-HCH/-HCH>4) and significant presence of DDT metabolites with fresh inputs into the Indus River as indicated by the ratios of (DDE+DDD)/DDTs (0.27-0.96). The partitioning of OCPs between the sediments and water can be explained by two carbon Freundlich adsorption model which included both organic carbon and black carbon pools as partitioning media.

The Indus River dolphin (Platanista gangetica minor) is a freshwater cetacean that occurs only in the Indus River system in Pakistan and India. This review provides a comprehensive summary of issues surrounding Indus dolphin conservation, and includes a description of their distribution, the threats they face and a discussion of conservation and research activities, options and priorities. Information was gathered from published current and historical literature, newspaper articles, and unpublished reports. Prior to construction of the Indus Irrigation system dolphins occurred in 3500. km of the Indus River system. Their range has now declined by 80% due to fragmentation of river habitat by barrages and large-scale diversion of water for irrigated agriculture. The subspecies was estimated to number approximately 1450 individuals in 2011, and occurs in 6 subpopulations, three of which are probably too small to persist. There is an urgent need to evaluate whether dolphins move through barrages, as this has the potential to extirpate upstream subpopulations. Pre-requisites for dolphin translocations to combat this problem are outlined. Mortality in fishing gear and high levels of chemical pollution in water courses are both increasing threats exacerbated by depleted flows. Research and conservation priorities include maintenance of river flows, mortality monitoring, canal rescues and community-based conservation. Conservation and research action is urgently needed to prevent the Indus dolphin from succumbing to the same fate as the baiji. © 2015 Elsevier B.V.

Based on the recent rediscovery of a dice snake (Natrix tessellata) in the Karakoram mountains of north-central Pakistan (western Karakoram) and the only other records from northwestern Pakistan we utilize contemporaneous information on the ecology of N. tessellata and climate fluctuations during the Holocene to analyze its limited distribution to a few mountain valleys. We elaborate several plausible expansion routes from a glacial refugium in northern Afghanistan through the Hindu Kush Mountain Range into Pakistan and the western Karakoram. The apparent range restriction of N. tessellata to the mountains of northern Pakistan is discussed in regards to postglacial expansion speed and routes, available period during the Holocene, habitat requirement, competition with another semi-aquatic water snake, Xenochrophis piscator, and potential misidentification with the latter species.

The cliff-nesting Long-billed Vulture Gyps indicus is one of four critically endangered Asian Vultures. In India, this species has declined catastrophically, but in Pakistan only small population declines have been recorded. Mortality of this species has been linked to poisoning by veterinary diclofenac, which was banned throughout south Asia in 2006. Between 2003 and 2012 we measured abundance of adult, sub-adult, juvenile, and dead vultures, and nest occupancy and productivity at the largest known Long-billed Vulture colony in Pakistan. We compared population parameters from before (2003-2006) and after (2007-2012) the ban on veterinary diclofenac. Our data and models indicate that vulture abundance, nest occupancy, and nest productivity declined 61%, 73%, and 95%, respectively, in the three years before the diclofenac ban, and then increased 1-2 years after the ban by 55%, 52%, and 95%. Furthermore, we observed 87% of total vulture mortalities prior to the diclofenac ban. Our results demonstrate for the first time since the onset of the Asian vulture crisis that the ban on veterinary diclofenac is an effective management tool for reversing Long-billed Vulture population declines. © 2011 BirdLife International.
