Yet, these are being damaged and overexploited, ultimately to the detriment of humans. In addition, increasing incidence and intensity of natural disasters and climate change are having over-arching impacts on the environment. Sustainable development, often of the most vulnerable sectors of society, is thus being undermined. One of the key reasons why this damage continues is that an integrated approach is adopted rarely in disaster risk management. For example, relief organisations may focus on damage to life and property while others examine impacts on livelihoods. Very often, ecological services and their indirect economic values are omitted completely from assessments. Adaptation to climate change is ignored. Mainstreaming ecosystem concerns – both ecological and economical – into the development agenda and integrating them into disaster management, therefore, becomes essential. This manual attempts to provide background information and guidance for integrating environmental concerns into disaster management. Volume 1 of the manual describes briefly the framework of the Millennium Ecosystem Assessment (MA). The MA links clearly ecosystem well-being

  • The Use of Fish and Herptiles in Traditional Folk Therapies in Three
    Altaf et al. Journal of Ethnobiology and Ethnomedicine (2020) 16:38 https://doi.org/10.1186/s13002-020-00379-z RESEARCH Open Access The use of fish and herptiles in traditional folk therapies in three districts of Chenab riverine area in Punjab, Pakistan Muhammad Altaf1* , Arshad Mehmood Abbasi2*, Muhammad Umair3, Muhammad Shoaib Amjad4, Kinza Irshad2 and Abdul Majid Khan5 Abstract Background: Like botanical taxa, various species of animals are also used in traditional and modern health care systems. Present study was intended with the aim to document the traditional uses of herptile and fish species among the local communities in the vicinity of the River Chenab, Punjab Pakistan. Method: Data collected by semi-structured interviews and questionnaires were subsequently analyzed using relative frequency of citation (FC), fidelity level (FL), relative popularity level (RPL), similarity index (SI), and rank order priority (ROP) indices. Results: Out of total 81 reported species, ethnomedicinal uses of eight herptiles viz. Aspideretes gangeticus, A. hurum, Eublepharis macularius, Varanus bengalensis, Python molurus, Eryx johnii, Ptyas mucosus mucosus, Daboia russelii russelii and five fish species including Hypophthalmichthys molitrix, Cirrhinus reba, Labeo dero, Mastacembelus armatus, and Pethia ticto were reported for the first time from this region. Fat, flesh, brain, and skin were among the commonly utilized body parts to treat allergy, cardiovascular, nervous and respiratory disorders, sexual impotency, skin infections, and as antidote and anti-diabetic agents. Hoplobatrachus tigerinus, Duttaphrynus stomaticus, and Ptyas mucosus mucosus (herptiles), as well as Labeo rohita, Wallago attu, and Cirrhinus reba (fish) were top ranked with maximum informant reports, frequency of citations, and rank order priority.

It is a contracted form of biological diversity encompassing the variety of all forms on the earth. It is identified as the variability among living organisms and the ecological complexes of which they are part including diversity between species and ecosystems.

  • Whole-Genome Sequencing of Wild Siberian Musk
    Yi et al. BMC Genomics (2020) 21:108 https://doi.org/10.1186/s12864-020-6495-2 RESEARCH ARTICLE Open Access Whole-genome sequencing of wild Siberian musk deer (Moschus moschiferus) provides insights into its genetic features Li Yi1†, Menggen Dalai2*†, Rina Su1†, Weili Lin3, Myagmarsuren Erdenedalai4, Batkhuu Luvsantseren4, Chimedragchaa Chimedtseren4*, Zhen Wang3* and Surong Hasi1* Abstract Background: Siberian musk deer, one of the seven species, is distributed in coniferous forests of Asia. Worldwide, the population size of Siberian musk deer is threatened by severe illegal poaching for commercially valuable musk and meat, habitat losses, and forest fire. At present, this species is categorized as Vulnerable on the IUCN Red List. However, the genetic information of Siberian musk deer is largely unexplored. Results: Here, we produced 3.10 Gb draft assembly of wild Siberian musk deer with a contig N50 of 29,145 bp and a scaffold N50 of 7,955,248 bp. We annotated 19,363 protein-coding genes and estimated 44.44% of the genome to be repetitive. Our phylogenetic analysis reveals that wild Siberian musk deer is closer to Bovidae than to Cervidae. Comparative analyses showed that the genetic features of Siberian musk deer adapted in cold and high-altitude environments. We sequenced two additional genomes of Siberian musk deer constructed demographic history indicated that changes in effective population size corresponded with recent glacial epochs. Finally, we identified several candidate genes that may play a role in the musk secretion based on transcriptome analysis. Conclusions: Here, we present a high-quality draft genome of wild Siberian musk deer, which will provide a valuable genetic resource for further investigations of this economically important musk deer.

We revealed the phylogeographic structure of the species by using mitochondrial control region, as well as comparing morphological characters. The distinct geographic distributions of two major clades suggest spatial and temporal separa- tions that coincide with important climatic and paleogeographic changes following the uplift of the Tibetan Plateau. Population expan- sion was inferred for the population at the platform of the Plateau 0.17 million years before present (Ma B.P.), and restricted gene Xow with isolation by distance was detected within this region, congruent with expansion occurring after the extensive glacial period. A signiW- cant decrease in body size with decreasing altitude was found, possibly indicating selection for larger-sized birds at higher altitude. © 2006 Elsevier Inc. All rights reserved.

  • Length-Weight Relationship and Sex Ratio of Some Cyprinid Fish Species from Taungthaman Lake
    Length-Weight Relationship and Sex Ratio of Some Cyprinid Fish Species From Taungthaman Lake Soe Soe Aye and Ma Khaing Abstract The present study describe the length-weight relationships LWR condition factor (K), relative condition factor (Kn) and sex ratio of three cyprinid small indigenous fish species; Amblypharyngodon atkinsonii, Puntius sarana and Puntius chola from Taungthaman Lake, Mandalay Region. A total numbers of 252 A. atkinsonii, 220 P.sarana and 249 P.chola were collected from November 2015 to February 2016. In LWR (W= aLb) values of exponent 'b' were observed to be 2.577, 2.519, 2.539 for male, female and combined of A. atkinsonii, 2.913, 2.751, 2.809 for male, female and combined of P.sarana and 2.684, 2.784, 2.746 for male, female and combined of P.chola. The correlation coefficient 'r' was observed to be 0.91, 0.905, 0.862 for male, female and combined of A.atkinsonii, 0.869, 0.9, 0.875 for male, female and combined of P.sarana and 0.85, 0.918, 0.914 for male, female and combined of P.chola. The values of k were 1.06 in A.atkinsonii, 1.48 in P.sarana and 1.37 in P.chola from pooled data. The values of Kn were observed to be 1.05, 1.06 for male and female of A.atkinsonii, 1.09, 1.05 for male and female of P.sarana and 1.07, 1.05 for male and female of P. chola.

It originates from the central hills and flows through a diverse array of landscapes, including some of the most urbanized regions and intensive land uses. Kelani River suffers a multitude of environmental issues: illegal water diversions and extractions, impoundment for hydroelectricity generation, and pollution, mostly from agrochemicals, urban runoff, industrial discharges, and domestic waste. Moreover, loss of riparian forest cover, sand-mining, and unplanned development in floodplains have accentuated the environmental damage. In this study, based on Kelani River basin, we reviewed the status of biodiversity, threats encountered, conservation challenges, and provided guidance for science-based conservation planning. Kelani River basin is high in biodiversity and endemism, which includes 60 freshwater fish species of which 30 are endemic.
