Article Synopsis
  • Urban rodents at Kolkata's Alipore Railway Station were studied for their role in spreading zoonotic pathogens, particularly Bartonella spp., through fleas, highlighting the link between high rodent populations and increased disease risk due to nearby human activity.
  • The study involved collecting and identifying rodents and fleas, as well as detecting Bartonella DNA to understand its prevalence and phylogenetic relationships among different species.
  • Results showed a high prevalence of Bartonella infections in rodents (53.33%) and fleas (79.1%), with some haplotypes indicating cross-species transmission between rodents, fleas, and humans, underscoring the public health implications of these findings.

Background: Captive breeding programs play a vital role in conservation of threatened species, necessitating an understanding of genetic diversity among captive individuals to ensure long-term genetic viability, appropriate mate selection, and successful reintroduction to native habitats.

Methods And Results: We did not observe any recent genetic bottleneck, and population showed moderate genetic diversity. The estimated effective population size, representing individuals capable of contributing genetically to future generations, was estimated as 18.

It is becoming more widely recognised that free-ranging dogs, which have a nearly global distribution, threatening native wildlife. Their increasing population and spread to new areas is of growing concern for the long-term viability of wildlife species. Hence, it is imperative to understand the factors responsible for their infestation and map areas where native species are most vulnerable.

The trans-Himalayan region of India, although have xeric features, still supports a unique assemblage of biodiversity, including some of the charismatic and endemic species. In the present study, we studied blue sheep (Pseudois nayaur) across the distribution range in the Western trans Himalayas of India and found about 18,775 km area suitable for blue sheep. The explicit Bayesian based spatial and non-spatial population structure analysis assigned blue sheep into two genetic populations, i.

Pleistocene glaciations had profound impact on the spatial distribution and genetic makeup of species in temperate ecosystems. While the glacial period trapped several species into glacial refugia and caused abrupt decline in large populations, the interglacial period facilitated population growth and range expansion leading to allopatric speciation. Here, we analyzed 40 genomes of four species of ibex and found that Himalayan ibex in the Pamir Mountains evolved independently after splitting from its main range about 0.

Wildlife corridors that connect mosaic habitats in heterogeneous mountainous landscapes can be of high significance as they facilitate the genetic and demographic stability of free-ranging populations. Peripheral populations of widespread species are usually ignored in conservation planning. However, these populations retain locally common alleles and are genetic reservoir under the changing climatic conditions.

Large forested landscapes often harbour significant amount of biodiversity and support mankind by rendering various livelihood opportunities and ecosystem services. Their periodic assessment for health and ecological integrity is essential for timely mitigation of any negative impact of human use due to over harvesting of natural resources or unsustainable developmental activities. In this context, monitoring of mega fauna may provide reasonable insights about the connectivity and quality of forested habitats.

Background: Populations exhibit signatures of local adaptive traits due to spatial and environmental heterogeneity resulting in microevolution. The blue sheep is widely distributed across the high Asian mountains and are the snow leopard's principal prey species. These mountains differ in their evolutionary history due to differential glaciation and deglaciation periods, orography, and rainfall patterns, and such factors causes diversification in species.

Background: Himalayan goral (Naemorhedus goral), solitary cliff-dwelling species and are distributed throughout the Indian Himalayan region. Its populations across the range are facing severe threats due to habitat loss, fragmentation and changes in the land-use patterns by various anthropogenic activities.

Methods And Results: We carried out genetic analyses of Himalayan goral using the mitochondrial control regions and microsatellite loci (n = 10) in the Uttarkashi district of Uttarakhand.

Poaching of South Asian river dolphins is considered one of the main reasons for the rapid decline of their natural populations. To curb the escalated rate of poaching, high numbers of oil and meat seizures are recovered with subsequent convictions by the law enforcement agencies. In this connection, we report a case where suspected animal oil was confiscated by the forest official of West Bengal.

Hangul (Cervus hanglu hanglu), the only red deer subspecies surviving in the Indian subcontinent, is of top conservation priority with global importance. Unfortunately, it has lost much of its historical distribution range, and it is now confined to Dachigam landscape within the Kashmir valley of India. The Government of India initiated a recovery plan in 2008 to augment their numbers through ex-situ conservation programs.

Introduction: Throughout the world each year, an estimated 23% of the 4 million neonatal deaths and 8% of all deaths in <5 years of age are associated with signs of asphyxia at birth.

Aim: To study the role of cord arterial blood gas analysis at birth and serial Thompson score in predicting the early neonatal outcome in post asphyxiated term neonates.

Materials And Methods: The study was conducted in Department of Paediatrics, in Neonatal Intensive Care Unit (NICU), Hindu Rao Hospital, New Delhi from May 2014 to February.
