The hypoxia adaptation to high altitudes is of considerable interest in the biological sciences. As a breed with adaptability to highland environments, the Tibetan chicken (Gallus gallus domestics), provides a biological model to search for genetic differences between high and lowland chickens. To address mechanisms of hypoxia adaptability at high altitudes for the Tibetan chicken, we focused on the Endothelial PAS domain protein 1 (EPAS1), a key regulatory factor in hypoxia responses. Detected were polymorphisms of EPAS1 exons in 157 Tibetan chickens from 8 populations and 139 lowland chickens from 7 breeds...

Background and Objectives Although the frequency of cardiovascular events, especially the end manifestation of myocardial infarction, has decreased in recent years, cardiovascular disease continues to be one of the most frequent illnesses. Also it is known that the cardiac system sustains more stress at high altitudes than it does at intermediate altitudes. This leads to the question if young alpinists should undergo cardiac evaluation before setting out for a trip to the Himalayas or the Andes Mountains...

Under anthropogenic climate change, many species are expanding their ranges to higher latitudes and altitudes, resulting in novel species interactions. The consequences of these range shifts for native species, patterns of local biodiversity, and community structure in high latitude ecosystems are largely unknown but critical to understand in light of widespread poleward expansions by many warm-adapted generalists. Using niche modelling, phylogenetic methods, and field and laboratory studies, we investigated how colonisation of Scotland by a range expanding damselfly, Ischnura elegans, influences patterns of competition and niche shifts in native damselfly species, and changes in phylogenetic community structure...

Approximately, 140 million people worldwide live permanently at high altitudes (HAs) and approximately another 40 million people travel to HA area (HAA) every year for reasons of occupation, sports or recreation. In India, whole of Ladakh region, part of Northwest Kashmir, Northern part of Sikkim and Tenga valley of Arunachal are considered inhabited areas of HAA. The low quantity of oxygen, high exposure of ultraviolet (UV) light, very low humidity, extreme subzero temperature in winter, high wind velocity, make this region difficult for lowlanders as well as for tourists...

High altitude pulmonary edema (HAPE) occurs mainly under conditions such as high altitude, rapid ascent, or hypoxia. Previous studies suggest that ADRB2, GNB3, TH, and GSTP1 polymorphisms are associated with various lung diseases. We evaluated whether those polymorphisms are associated with the risk of HAPE in a Chinese Han population. ADRB2, GNB3, TH and GSTP1 polymorphisms were genotyped using a Sequenom MassARRAY. Logistic regression, adjusted for age and gender, was used to evaluate the association between the genotypes and the risk of HAPE by computing odds ratios (ORs) and 95% confidence intervals (95% CIs)...

Many species of Schizothoracine, a sub-family of Cyprinidae, are highly endemic to the Qinghai-Tibetan Plateau (QTP). To characterize the adaptive changes associated with the Schizothoracine expansion in high-altitudes, we sequenced tissue transcriptomes of two highland and two sub-highland Schizothoracines, and analyzed gene evolution patterns by comparing to lowland cyprinids. Phylogenetic tree reconstruction and divergence time estimation indicated that the common ancestor of Schizothoracine fishes lived around 32...

BACKGROUND: The field ecology of the pollen beetle Meligethes aeneus and its damaging effects on oilseed rape crops are well understood. However, the flight behaviour of M. aeneus, in particular the drivers for migratory movements across the landscape, is not well studied. We combined three established methodologies; suction traps, vertical-looking radar and high-altitude aerial netting to demonstrate that M. aeneus fly at a range of altitudes at different points during its active season...

A polyphasic study was undertaken to determine the taxonomic status of a Streptomyces strain which had been isolated from a high altitude Atacama Desert soil and shown to have bioactive properties. The strain, isolate H9(T), was found to have chemotaxonomic, cultural and morphological properties that place it in the genus Streptomyces. 16S rRNA gene sequence analyses showed that the isolate forms a distinct branch at the periphery of a well-delineated subclade in the Streptomyces 16S rRNA gene tree together with the type strains of Streptomyces crystallinus, Streptomyces melanogenes and Streptomyces noboritoensis...

Mesostoinae is a poorly understood subfamily, with a classic Gondwanan distribution. Historically, its members have been classified in as many as nine different subfamilies and/or tribes. Formally comprising seven genera (Andesipolis, Aspilodemon, Hydrangeocola, Opiopterus, Mesostoa, Praonopterus and Proavga), there are at least six more genera (Apoavga, Austrohormius, Canberria, Doryctomorpha, Hormiitis and Neptihormius) to be included based on morphological and geographical data. Here, we discuss the placement of the Neotropical genus Andesipolis Whitfield & Choi within Mesostoinae, and provide a revised definition of the subfamily...
