arabian sea humpback whale cites status

stream The problem is how this information is uniformly and consistently applied, particularly as it relates to management decisions. ! We recommend an amendment of the status of the population to “Critically Endangered” on the IUCN Red List.Understanding the patterns underlying the division of natural populations into smaller units is essential for the conservation and management of biodiversity. This timing also corresponds to the estimated radiation of a second clade from the Southern Hemisphere to the North Pacific,The switching of a non-migratory population to a Northern Hemisphere breeding cycle is an interesting biological conundrum and while this is beyond the scope of our research, it is tempting to hypothesize an adaptive response of the ASHW to the Arabian Sea seasonal cycle of temperature and productivity in connection to the monsoon seasons. Biopsies were taken under permits numbers 10/2000, 6/2002 and 07/2004, issued by the Directorate - General of Nature Conservation of the Ministry of Regional Municipalities, Environment and Water Resources of the Sultanate of Oman. 6 0 obj A primary productivity collapse occurred ∼15,000 ya, coinciding with the apparent signal of population decline in the mtDNA BSP. Our findings suggest this is the world's most isolated humpback whale population, which, when combined with low population abundance estimates and anthropogenic threats, raises concern for its survival. /Width 264 70 kya. I agree that there are divisions below the species level for CITES permits were issued by the same institution (permit numbers 3/2002, 13/2002, 1/2003 and 7/2003).Tissue samples were collected during small-boat surveys between 1999 and 2004. There is a critical need to initiate a systematic effort to study ASHW using a combination of acoustic and visual monitoring methods to bridge the information gap for this species in Indian waters.’’ He informed that the study aims to implement a community based monitoring network to report sightings and strandings of cetaceans along the Maharashtra coast. Throughout the region, stakeholder awareness of the conservation status of Arabian Sea humpback whales and the many threats they face is low. Analyzed the data: CP ARA ML HCR. Arabian sea humpback whales isolated for 70,000 years Date: December 3, 2014 Source: Wildlife Conservation Society Summary: Scientists have made a … In the phylogenetic tree (.Stock X haplotypes are indicated by arrows.a) top left: pairwise measures of mtDNA differentiation between Stock X (Arabian Sea) and Stocks C to F in the Southern Hemisphere, and two sampling location in the North Pacific (grouped as NP). >> A clear understanding of population structure is essential for assessing conservation status and implementing management strategies. /BitsPerComponent 8 The IWC has defined seven Southern Hemisphere humpback whale breeding ‘Stocks’ (A–G, see.Inset: sampling locations used in this study, including six Southern Hemisphere breeding Stocks (A–F), the North Pacific and the Arabian Sea (boxed region).In this paper we combine mtDNA and nuclear microsatellite data with traditional and coalescent-based statistical analyses of population structure to: i) comprehensively test hypotheses on the origin and inter-population connections, if any, of ASHW; and ii) assess population status from a conservation genetics point of view. Crisp news summaries and articles on current events about Arabian Sea Humpback Whale for IBPS, Banking, UPSC, Civil services. A small, non-migratory population of humpback whales in the Arabian Sea is classified as “Endangered” on the IUCN Red List of Threatened Species, an assessment constrained by a lack of data, including limited understanding of its relationship to other populations. This was necessitated as Humpback Whales found along the western coast of India are supposedly part of the distinct Arabian Sea population and ASHW are currently listed as endangered. $4�%�&'()*56789:CDEFGHIJSTUVWXYZcdefghijstuvwxyz�������������������������������������������������������������������������� ? *�6c�oU��`. Following an extensive review process that started in 2009 and was finalized in September 2016, the United States National Oceanic and Atmospheric Administration has revised the status of humpback whale populations around the world under the US Endangered Species Act (ESA). The current estimates for population size (82 individuals using mark-recapture data and 90–142 individuals using genetic data) and bottleneck timing are compatible with an 80% reduction. At the maiden meeting of the State Board for Wildlife, chaired by Chief Minister Uddhav Thackeray on Friday, it was decided that forest management and aquatic wildlife management will have to be more robust and empathetic towards biodiversity and ensure development that is balanced and sustainable. 1.2 Summary of Arabian Sea Humpback Whale population status and knowledge 1.2.1 The Unfolding Mystery: The Arabian Sea Humpback Whale – the only known non-migratory population of humpback whales in the world - Gianna Minton, WWF Gabon/Environment Society Oman (ESO) and Andrew Willson, ESO Contributed reagents/materials/analysis tools: TC RB HCR. A consensus region of 486 bp of the mtDNA control region was assembled in which a total of 7 maternal haplotypes was detected from 24 polymorphic sites (GenBank Accession Numbers GQ913845, GQ913846, GQ913848, GQ913701, GQ913706, GQ913709, GQ913715).
