However, it is clear that a desirable level of taxonomic resolution has not yet been attained as their taxonomic assignments are somewhat arbitrary. In this paper, we discuss two lesser-known gecko species, Cyrtopodion baturense (Khan and Baig 1992) and C. walli (Ingoldby 1922). One adult specimen of Cyrtopodion baturense (the only known specimen other than the type series) and a series of 53 C. walli collected by Walter Auffenberg and the Zoological Survey Department of Pakistan (ZSD) and subsequently deposited in the University of Florida Herpetology collection were compared to the type specimens. Specimens were examined for 46 morphological characters and measurements. Cyrtopodion baturense and C. walli are diagnosable and confirmed to be distinct species. Cyrtopodion baturense is known only from the holotype locality of Pasu and the nearby village of Dih, Hunza District, in the Gilgit Agency, Federally Administered Northern Areas (FANA), Pakistan, at 2,438–3,078 m elevations.

  • Rainwater Harvesting in Cholistan Desert: a Case Study of Pakistan
    Rainwater Harvesting in Cholistan Desert: A Case Study of Pakistan Muhammad Akram Kahlown1 Abstract About 70 million hectares of Pakistan fall under arid and semi-arid climate including desert land. Cholistan is one of the main deserts covering an area of 2.6 million hectares where water scarcity is the fundamental problem for human and livestock population as most of the groundwater is highly saline. Rainfall is the only source of freshwater source, which occurs mostly during monsoon (July to September). Therefore, rainwater harvesting in the desert has crucial importance. The Pakistan Council of Research in Water Resources (PCRWR) has been conducting research studies on rainwater harvesting since 1989 in the Cholistan desert by developing catchments through various techniques and constructing ponds with different storage capacities ranging between 3000 and 15000 m3. These ponds have been designed to collect maximum rainwater within the shortest possible time and to minimize seepage and evaporation losses. As a result of successful field research on rainwater harvesting system, PCRWR has developed 92 rainwater harvesting systems on pilot scale in Cholistan desert. Each system consists of storage reservoir, energy dissipater, silting basin, lined channel, and network of ditches in the watershed. The storage pond is designed to collect about 15000 m3 of water with a depth of 6 m. Polyethylene sheet (0.127 mm) on bed and plastering of mortar (3.81 cm) on sides of the pond was provided to minimize seepage losses. All these pilot activities to harvest rain have brought revolution in the socio-economic uplift of the community. These activities have also saved million of rupees during the recent drought.

But police work is also related to stress, which is evident among the police personnel. Several studies reported the presence of stress among police personnel, which can have an impact on their personal and professional life. The night shifts, stressful events, frequent transfers, along with administrative/ organizational pressure, pose the police personnel to and physical and psychological danger. The occupational stress faced by the police personnel lead to anger and aggression and can adversely affect the family and personal life. The present article focuses on nding out the impact of job stress on various aspects of police personnel life, such as personal, social, and professional life.

The topographic form and the soil characteristics of Cholistan is the best catchment area for rainwater harvesting. Different profiles point out that the area is very poorly drained, capable of generating maximum runoff after absorbing minimum water. Water intake characteristics of fine textured soils show that infiltration rate is low to very low. Findings show that there is direct relationship between water availability and poverty reduction. Study also sheds light on both strengths and limitations of the indigenous technology on reducing rural poverty and recommends using this technology along with modern water harvesting techniques.

In these environments, microorganisms endure a multitude of physico- chemical stresses, including low water potential, carbon and nitrogen starvation, and extreme temperatures. In this review, we summarize our current understanding of the energetic mechanisms and trophic dynamics that underpin microbial function in desert ecosystems. Accumulating evidence suggests that dormancy is a common strategy that facilitates microbial survival in response to water and carbon limitation. Whereas photoautotrophs are restricted to specific niches in extreme deserts, meta- Citation Leung PM, Bay SK, Meier DV, Chiri E, bolically versatile heterotrophs persist even in the hyper-arid topsoils of the Atacama Cowan DA, Gillor O, Woebken D, Greening C. 2020. Energetic basis of microbial growth and Desert and Antarctica. At least three distinct strategies appear to allow such micro- persistence in desert ecosystems. mSystems organisms to conserve energy in these oligotrophic environments: degradation of 5:e00495-19.
