| complete mitochondrial genome sequence of the himalayan griffon, gyps himalayensis (accipitriformes: accipitridae): sequence, structure, and phylogenetic analyses. | this is the first study to describe the mitochondrial genome of the himalayan griffon, gyps himalayensis, which is an old world vulture belonging to the family accipitridae and occurring along the himalayas and the adjoining tibetan plateau. its mitogenome is a closed circular molecule 17,381 bp in size containing 13 protein-coding genes, 22 trna coding genes, two rrna-coding genes, a control region (cr), and an extra pseudo-control region (ccr) that are conserved in most accipitridae mitogenome ... | 2019 | 31410282 |
| status, ecology, and conservation of the himalayan griffon gyps himalayensis (aves, accipitridae) in the tibetan plateau. | the dramatic population crashes of 3 species of gyps vulture have raised concerns about the status of their lesser-known congeners. among these is the himalayan griffon, g. himalayensis, an iconic vulture of the tibetan plateau. the continued existence of this scavenger has not only ecological but also cultural implications because of their unique role in the centuries-old sky burial tradition that is followed by nearly 5 million tibetan people. a lack of baseline information of the himalayan gr ... | 2009 | 19580034 |
| maxent modeling for predicting the spatial distribution of three raptors in the sanjiangyuan national park, china. | upland buzzard (buteo hemilasius), saker falcon (falco cherrug), and himalayan vulture (gyps himalayensis) are three common large raptors in the sanjiangyuan national park (snp), china's first national park. among them, upland buzzard and saker falcon play a significant role in controlling plateau rodent populations and reducing the transmission of pathogens carried by rodents. the himalayan vulture can provide services for the redistribution and recycling of nutrients in the ecosystem, and play ... | 2019 | 31236249 |
| residues of diclofenac in tissues of vultures in india: a post-ban scenario. | populations of three resident gyps species (indian white-backed vulture gyps bengalensis, indian vulture gyps indicus, and slender-billed vulture gyps tenuirostris) in india have decreased by more than 90% since mid 1990s, and they continue to decline. experimental studies showed the mortality of vultures to be due to renal failure caused by diclofenac, a nonsteroidal anti-inflammatory drug. india, pakistan, and nepal banned the veterinary usage of diclofenac in 2006 to prevent further decline i ... | 2018 | 29159701 |
| multidrug resistance protein 4 (mrp4) is expressed as transcript variants in both gallus domesticus and gyps himalyanesis. | the non-steroidal anti-inflammatory drug (nsaid) diclofenac, known to cause hyperuricemia and concomitant visceral gout in gyps vultures is suggested to be a result of interference with renal uric acid excretion. three species of gyps vultures are on the verge of extinction due to nephrotoxic veterinary diclofenac having entered the food chain, notwithstanding the fact that the toxicity of different avian species to the nsaids like diclofenac varies. the multidrug resistance protein 4 (mrp4), an ... | 2019 | 30562604 |
| bio-logging, new technologies to study conservation physiology on the move: a case study on annual survival of himalayan vultures. | bio-logging, the on-animal deployment of miniaturised electronic data recorders, allows for the study of location, body position, and physiology of individuals throughout their ontogeny. for terrestrial animals, 1 hz gps-position, 3d-body acceleration, and ambient temperature provide standard data to link to the physiology of life histories. environmental context is added at ever finer scales using remote sensing earth observation data. here we showcase the use of such bio-logging approaches in ... | 2017 | 28612235 |
| actinomyces vulturis sp. nov., isolated from gyps himalayensis. | two strains of gram-stain-positive, facultatively anaerobic, non-spore-forming short rods (vul7t and vul8) were isolated from rectal swabs of old world vultures, namely gyps himalayensis, in tibet-qinghai plateau, china. optimal growth occurred at 37 °c, ph 6-7, with 1 % (w/v) nacl. phylogenetic analysis based on 16s rrna gene sequences classified the two strains to the genus actinomyces, with highest 16s rrna gene sequence similarity (95 %) to type strains of actinomyces haliotis, actinomyces r ... | 2017 | 28629509 |
| molecular sexing of threatened gyps vultures: an important strategy for conservation breeding and ecological studies. | during the last two decades populations of three resident species of gyps vulture have declined dramatically and are now threatened with extinction in south asia. sex identification of vultures is of key importance for the purpose of conservation breeding as it is desirable to have an equal sex ratio in these monogamous species which are housed together in large colony aviaries. because vultures are monomorphic, with no differences in external morphology or plumage colour between the sexes, othe ... | 2012 | 23316450 |

| behavioural adaptations to flight into thin air. | soaring raptors can fly at high altitudes of up to 9000 m. the behavioural adjustments to high-altitude flights are largely unknown. we studied thermalling flights of himalayan vultures (gyps himalayensis) from 50 to 6500 m above sea level, a twofold range of air densities. to create the necessary lift to support the same weight and maintain soaring flight in thin air birds might modify lift coefficient by biophysical changes, such as wing posture and increasing the power expenditure. alternativ ... | 2016 | 28120805 |
