Given the wide range of topo-geographical features present in the State of Uttarakhand, all the 9 species of vultures of the Indian sub-continent are found here. However, the rapid and alarming decline in vulture population is a matter of great concern for all concerned. And therefore, there is an urgent need to identify the causes of decline and other threats that plague the vulture population in the country, especially in the State of Uttarakhand.

Here, we report species identification and assign the geographical origin of a fully tanned animal skin using complete mtDNA cytochrome b gene. A nucleotide sequence of 1140 bp cytochrome b was generated from the DNA extracted from the small piece of skin from the inner ear (IEP-01). GenBank BLAST search of the unknown Cyt b (1140bp) sequence against the full range of published Rangifer tarandus has facilitated in identification of species and ascertaining the species of origin with high meta probability (100%). We determined that the seized unknown skin is wild reindeer (R.t. groenlandicus) and has been originated from Canada, where this Least Concern species under the IUCN red list. We propose to establish genetic database across the range of the species threatened due to illegal trade to determine hotspots of poaching.

The Tharu Tribe is indigenous people living in Tarai plain on the border of India and Nepal. The Tharu tribe is one of the most populous tribes of India and mostly populations (approximately 80%) of India are living in Khatima and Sitarganj tehsil of UdhamSingh Nagar district (Uttarakhand). Tharu is recognised as a scheduled tribe by the Government of India. The aim of this study to see the health status of Tharu population on the basis of blood parameters i.e. RBC, WBC, Hemoglobin (Hb), Platelet, Hematocrit, MCV, Rh factors etc and find out the factors affecting their health. Most of the populations were found to be suffering from Anaemia and Malnutrition. The percentage of Anaemia is more in women compared to men in Tharu population. These results indicate a lack of health awareness on healthy lifestyle and also they have no any idea about healthy nutritious diet etc. They are inadequate to take nutritious substances (vitamins, proteins, minerals etc) because health status of this community is directly proportional to economic (financial) and Socio-cultural conditions of these peoples. Therefore the present study provides important data, to the government and other agencies so is to control health problem of Tharu tribes in Sitarganj block, UdhamSingh Nagar District in Uttarakhand, India. This step will be helpful for improve their health status and development. This study also helpful to apply on other tribles community present in India and another part of the world.

In the present study based on non-invasive samples, we give the preliminary genetic documentation of snake species by using cytochrome b (Cyt b) and cytochrome c oxidase subunit I (COI) universal mitochondrial primers from Uttarakhand (UK), India. We sampled n=11 shed skin of unknown snake species from four different locations in Uttarakhand, India. The success rate of genomic DNA isolation, PCR amplification, and sequencing from collected samples was 100%. Afterward, in the genetics analysis, 8 out of 11 samples matched with Least Concern ver3.1 Rat snake species, two samples paired with Checkered keelback snake, and one sample matched with Indian cobra. Subsequently, 149 (Cyt b) and 207 (COI) species-specific fixed SNPs were observed. The obtained interspecific sequences divergences based on two mitochondrial loci among three snake species also show the high v...

The present paper describes a short study where a blood stain sample was recovered from an area outside the protected area network and used to determine a species identity. The mitochondrial DNA region of the questioned sample was amplified and sequenced using universal primers of cytochrome b gene (Cyt b) and 16S ribosomal RNA (16S rRNA) for species identity. The obtained sequencing results were compared with the most homologous sequences extracted from the NCBI-GenBank database. A phylogenetic tree was prepared with the aligned sequences to determine the species identity with strong bootstrap support. The mean distance and species score generated revealed that the grade of sequence similarity showed maximum homology (100 %) with the sequence obtained from the database. Based on the genetic analysis, the collected sample related to Indi...

The present work provides genetic proof that the Hatha Jodi sold in three local markets of Uttarakhand contained material from the Varanus species, species protected under the Indian Wildlife (Protection) Act, 1972. A total of eight samples were bought, two each from the local markets in Haridwar and Rishikesh, three from Dehradun and one from an online source (Amazon). The initial inspection confirmed that two of the samples were made of plastic material. Therefore only the other six samples were subjected to DNA analysis. DNA sequences were successfully obtained and matched with reference sequences available in NCBI Genbank database through BLAST search tool for species identification. All the six samples matched 100% with the Indian monitor lizard. The findings indicate how commercialization and the wildlife trade are playing a role in decline of the population of the Indian monitor lizard. If strong protection measures are not taken as soon as possible, the Indian monitor lizards will go Extinct very soon. Therefore, we suggest that the Government and Wildlife enforcement agencies take serious action against the illegal articles available in the local markets of Uttarakhand under the name Hatha Jodi. Further, the government needs to take legal action against offenders in other states in which the product is available for sale.

Pangolin scales are believed to be used in Traditional Chinese Medicines (TCM) and meat is used as delicacies in restaurants. Of the eight extant species of pangolin, morphological discrimination is easy but the situation becomes precarious once the scales and meat samples are seized and it is difficult to identify species based on morphology in such cases. However, wildlife DNA forensics has played an instrumental role in the identification of species from such type of materials. The present study investigated that three mitochondrial genes (Cyt b, 16S rRNA, and 12S rRNA) clearly showed the variation among seven extant pangolin species (Manis culionensis; possibly extinct), whereas, maximum variation was obtained in cytochrome b when compared to another two mitochondrial genes. The present study revealed that obtained SNPs based on short sequence length (Intervals) within the three mitochondrial genes will be helpful to design the short molecular marker and species-specific probe that is used in wildlife forensic for identifying pangolin species from the degraded sample. We also advocate using more than one molecular marker for species discrimination so as to minimize any false identification of the mammal's species reported in the trade. Furthermore, data generated from the study would help in strengthening the DNA database of Indian pangolin species.

The taxonomy of all the eight extant pangolin species based on molecular genetics studies, remains unresolved and poorly examined. The present study is to address this lacuna by studying the phylogenetic, taxonomic status and molecular dating of Indian pangolin with other six out of eight extant pangolins (Sunda pangolin possibly extinct) based on complete coding region of mitochondrial cytochrome b gene. Overall sequences divergence among pangolins ranged between 0.01 ± 0.01 and 0.26 ± 0.03, where within 'Manis' it ranged between 0.01 ± 0.01 and 0.14 ± 0.03. Cytochrome b sequences based ph...

Uttarakhand is one of the hotspot where number of identified and unidentified skink species reported. Herein, we first time provided the 12S rRNA genetic reference database of four skink species, i.e. Eutropis macularia, Eutropis carinata, Asymblepharus himalayanus and Lygosoma punctata, in Rajaji Tiger Reserve (RTR), Uttarakhand (India). The identified four species belong to three different genera, where Eutropis carinata and Asymblepharus himalayanus listed Least Concern and Vulnerable in IUCN, respectively. Here, we collected tissue samples of four different skink species from Rajaji Tiger Reserve during field survey. After successful laboratory procedure, we compared obtained sequences with publically available genetic database and we observed four sequences matched with respective species. Furthermore, the evolutionary sequence divergence result revealed that the Eutropis carinata and Eutropis macularia are close to each other with 0.11 genetic distance. The present study indicates that the exact number and population distribution of skink species are unidentified; therefore, herein we suggest the proper screening of Uttarakhand population around should be investigated, further genetic study in combination with a good sampling strategy to investigate species biology and status for conservation program.

There are 12 identified species under Araniella genus and they are distributed in Palearctic region. Here, we used known N = 47 (2 from present study and 45 from GenBank) cytochrome oxidase 1 (CO1) sequences of A. cucurbitina representing seven different geographical groups, additionally 23 sequences of eight Araniella species were used for phylogenetic relationship. The CO1 (561 bp) sequences of A. cucurbitina consisted of n = 14 haplotypes, where haplotype 14 (Hap 14) represents Indian species, while all 13 haplotypes (Hap1-13) shared between six A. cucurbitina groups. The overall &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;h&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39; and &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;π&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39; diversities among seven groups of A. cucurbitina were 0.85291 and 0.00888, respectively, while overall evolutionary divergence was 0.04. The Indian Hap 14, showed minimum sequence divergence (0.02) from Italy and Czech Republic haplotypes (Hap 6), it means it is the closest group compared to others. Evolutionary divergence among eight species of Araniella ranges from 0.003 to 0.114. The maximum likelihood (ML) topology based on 14 haplotypes of A. cucurbitina was divided into two major clades and further two subclades. Furthermore, ML topology between eight species of Araniella was divided into three major clades, where A. cucurbitina and A. proxima clustered together in clade &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;A&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;, while six others were present together in clade &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;B&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39; and &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;C&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;. This study helps to identify the Indian species from the rest of Araniella species and other cucurbitina population across the world. This study further needs to be on a large scale to know the exact status distribution and molecular phylogeography of this single species of genus Araniella from India.

In India, small population of Chines Pangolin (Manis pentadactyla) are also present in the eastern part and protected under the Wildlife (Protection) Act, 1972 as a schedule I species along with Indian Pangolin. In national and international market the Indian Pangolin are highly in trade principally for its meat and scales. In curbing illegal wildlife, trade of Indian Pangolin on national and international level wildlife DNA forensics plays an important role in the identification of species from the seized material. We received n = 15 wildlife seizures assumed to be the scales of Pangolin from different state forest and the custom department for molecular analysis. The seizures sequenced for two mitochondrial genes i.e. Cyt b and 16S rRNA, which are often used in wildlife DNA forensic to species identification. The sequences thus generated from these seizures compared to the NCBI database through blast search tool and our laboratory-generated references, yielding 100% similarity with Indian Pangolin. We identified twelve (n = 12) Cyt b and five (n = 5) 16S rRNA species specific SNPs, fixed in Indian Pangolin. This study shows, the importance of authenticated references, DNA sequence data availability, highlighting the application of DNA forensics in identifying species from scales.

The phylogenetic status of the Hangul relative to the other members of the family Cervidae is not known because sequence data are not available in public databases. Therefore, this study was carried out to determine the phylogenetic status and delineate the genetic boundaries of the Hangul with respect to the other Red Deer subspecies on the basis of cytochrome b gene sequence data (ca 421 bp). There are three major monophyletic groups of the Red Deer in the phylogenetic tree, which are referred to as the western (Hap-01 to Hap-10), eastern (Hap-11 to Hap-20) and tarim (Hap-21 to Hap-25) groups. The overall haplotype diversity and per-site nucleotide diversity were 0.9771 (±0.0523) and 0.0388 (±0.00261), respectively. In the phylogenetic tree, the Hangul clustered with the tarim group (Yarkand and Bactrian Red Deer) with a strong bootstrap support (92%) and was found to be genetically closer to the Bactrian Red Deer than to the Yarkand Red Deer. Our molecular analysis supported the idea that the Hangul diverged from the Bactrian Red Deer and migrated to India from Tajikistan approximately 1.2 MYA.

This activity has serious effects not only on the specific, target populations but also on the dynamics and structures of other animal populations. Often the only evidence available for successful prosecution of poachers is in the form of small pieces of skin, bone, and meat. In such cases, forensic investigations can irrefutably establish the identity of the species involved in the illegal hunting by using genetic technologies. This articles describes an investigative study in a suspected wildlife hunting incident in which molecular biology techniques were employed to identify the species involved. Using fragments of cytochrome b (Cyt b) and 12S ribosomal RNA (12S rRNA) mitochondrial markers, the samples were confirmed to be from an IUCN Red List species, the Indian porcupine (Hystrix indica).This is the first genetic record of an Indian porcupine from the Uttarakhand population. The genetic analysis in this study was suitable for diagnosing the species and concluding a criminal investigation. Molecular forensic techniques can, therefore, provide an important tool that enables local law enforcement agencies to apprehend poachers. Meanwhile the present study represents a small step in reducing the hunting of porcupine in Uttarakhand as well as other adjoining states, with the aim of conserving biodiversity.

Here, we present preliminary findings on generating robust DNA barcode library of Cervids of India. The dataset comprising the DNA barcode library of seven deer species included in the genus Cervus, Axis and Muntiacus classified under family Cervidae. Mitochondrial Cytochrome C Oxidase subunit I gene of ca. 710 bp accepted widely as DNA barcode region, was used for generating species specific signature from 31 known samples of seven Indian deer species. Expectedly, the NJ tree clustered three genera i.e. Cervus, Axis and Muntiacus of Cervids of India into three clades. Further, the intra-and interspecies distances based on Kimura 2 parameter model also supported the results. The average intra-and interspecies sequence divergence were 0.011 (±0.09) and 0.65 (±0.14), respectively. The present study has exhibited that DNA barcoding has discriminating power to delineate boundaries among the closely related species. The data generated are of high importance to the law enforcement agencies in effective identification of species in wildlife offence cases. The similar approach can be utilized for generating DNA barcodes for other Indian mammals for making effective management and conservation action decisions.
