Mountain West AETC (AIDS Education and Training Center) ECHO (Extension for Community Healthcare Outcomes), a longitudinal HIV telemen-toring program, connects community providers and a multidisciplinary specialist team at the University of Washington. The program employs focused lectures and real-time case discussions to educate and support providers in low-resource and rural settings. We assessed the impact of the program on management of perinatal HIV through surveying community providers who participate, and reviewing cases presented by providers for consultation...

An upward shift in elevation is one of the most conspicuous species responses to climate change. Nevertheless, downward shifts and, apparently, the absences of response have also been recently reported. Given the growing evidence of multiple responses of species distributions due to climate change and the paucity of studies in the tropics, we evaluated the response of a montane bird community to climate change, without the confounding effects of land-use change. To test for elevational shifts, we compared the distribution of 21 avian species in 1998 and 2015 using occupancy models...

ETHNOPHARMACOLOGICAL RELEVANCE: The study area is known by its huge livestock resources with extensive ethnoveterinary practice. This knowledge was not documented scientifically until we proposed to do so. The study can aid in future planning of endangered species conservation as well as for experimental studies in search of modern pharmacotherapy. AIM OF THE STUDY: The study objective was to understand the extent of ethnoveterinary practice, methods, types of medicinal plant species used and to generate a comprehensive baseline data that can be used as a basis for further studies...

Background: Climate change and infectious diseases threaten animal and plant species, even in natural and protected areas. To cope with these changes, species may acclimate, adapt, move or decline. Here, we test for shifts in anuran distributions in the Luquillo Mountains (LM), a tropical montane forest in Puerto Rico by comparing species distributions from historical (1931-1989)and current data (2015/2016). Methods: Historical data, which included different methodologies, were gathered through the Global Biodiversity Information Facility (GBIF) and published literature, and the current data were collected using acoustic recorders along three elevational transects...

Planning and management needs up-to-date, easily-obtainable and accurate information on the spatial and social aspects of visitor behaviour in order to balance human use and impacts, and protection of natural resources in public parks. We used a web-based public participation GIS (PPGIS) approach to gather citizen data on visitor behaviour in Helsinki's Central Park in order to aid collaborative spatial decision-making. The study combined smartphone GPS tracking, route drawing and a questionnaire to examine differences between user groups in their use of formal trails, off-trail behaviour and the motivations that affect it...

BACKGROUND: Conservation of biodiversity is primary important of today's critically vulnerable environment. Efficient conservation can be possible only with the long-term participation and understanding of the communities. Ritual beliefs of the indigenous people are one of the important tools to understand the local communities and aid the nature conservation. In this paper, we documented contemporary ritual practices and ritual plant uses among the Naxi people and discussed the importance of traditional knowledge on ritual practice in the conservation of plants in the mountains presenting a case study of the Dongba culture...

Genetic rescue has now been attempted in several threatened species, but the contribution of genetics per se to any increase in population health can be hard to identify. Rescue is expected to be particularly useful when individuals are introduced into small isolated populations with low levels of genetic variation. Here we consider such a situation by documenting genetic rescue in the mountain pygmy possum, Burramys parvus. Rapid population recovery occurred in the target population after the introduction of a small number of males from a large genetically diverged population...

Histiocytic sarcoma (HS) is an aggressive malignant neoplasm of dendritic cell origin that is common in certain breeds of dogs. High prevalence of fatal, disseminated HS has been described in Bernese Mountain Dogs (BMDs). Support for genetic predisposition to develop HS has been presented in several studies, but to date, causative genetic events have not been reported. In addition, no driver mutations have been identified in tumours. Recently, E76K gain-of-function mutation in SHP2 encoded by the PTPN11 gene has been described in human histiocytic malignancies...

RNA-seq analysis on whitebark pine needles demonstrated that methyl jasmonate (MeJA)-triggered transcriptome re-programming substantially overlapped with defense responses against insects and fungal pathogens in Pinus species, increasing current knowledge regarding induced systemic resistance (ISR) to pathogens and pests in whitebark pine. Many whitebark pine populations are in steep decline due to high susceptibility to mountain pine beetle and the non-native white pine blister rust (WPBR). Resistance, including induced systemic resistance (ISR), is not well characterized in whitebark pine, narrowing the current options for increasing the success of restoration and breeding programs...

Lesotho, a small, mountainous country completely surrounded by the Republic of South Africa, has a population of approximately 2 million persons with an estimated gross national income of $1,280 per capita; 73% of the population resides in rural areas (1). Lesotho has a generalized human immunodeficiency virus (HIV) epidemic (2). In 2014, the prevalence of HIV infection among persons aged 15-49 years was 24.6%, with an incidence of 1.9 new infections per 100 person-years of exposure (3). As the leading cause of premature death, HIV/AIDS (acquired immunodeficiency syndrome) has contributed to Lesotho's reporting the shortest life expectancy at birth among 195 countries and territories (4)...

The black-necked crane (Grus nigricollis) is the only alpine crane species and is endemic to the Tibetan Plateau. The breeding habitats of this species are poorly understood, which greatly hampers practical research and conservation work. Using machine learning methods and the best-available data from our 7,000-kilometer mega-transect survey and open access data, we built the first species distribution model (SDM) to analyze the black-necked crane's breeding habitats. Our model showed that current conservation gaps account for 26...

Epstein-Barr virus (EBV) infects greater than 90% of humans, is recognized as a significant comorbidity with HIV/AIDS, and is an etiologic agent for some human cancers. The critically endangered mountain gorilla population was suspected of infection with an EBV-like virus based on serology and infant histopathology similar to pulmonary reactive lymphoid hyperplasia (PRLH), a condition associated with EBV in HIV-infected children. To further examine the presence of EBV or an EBV-like virus in mountain gorillas, we conducted the first population-wide survey of oral samples for an EBV-like virus in a nonhuman great ape...

The physicochemical characteristics, sensory quality, and antioxidant activity of tea infusions prepared with purified water (PW), mineral water (MW), mountain spring water (MSW), and tap water (TW) from Hangzhou were investigated. The results showed that the taste quality, catechin concentration, and antioxidant capacity of green, oolong, and black tea infusions prepared using MW and TW were significantly lower than those prepared using PW. Extraction of catechins and caffeine was reduced with high-conductivity water, while high pH influenced the stability of catechins...

Exposure to altitude results in multiple physiological consequences. These include, but are not limited to, a reduced maximal oxygen consumption, drop in arterial oxygen saturation, and increase in muscle metabolic perturbations at a fixed sub-maximal work rate. Exercise capacity during fixed work rate or incremental exercise and time-trial performance are also impaired at altitude relative to sea level. Recently, dietary nitrate (NO3(-)) supplementation has attracted considerable interest as a nutritional aid during altitude exposure...

BACKGROUND Tick bites are a source of illness and disease agents that may lead to morbidity and occasional fatalities in North Carolina. Public health interest in tick-borne illness and disease has increased due to continuing discoveries of tick-borne diseases and their increasing geographic spread and disease incidence. There are no data published on lay individuals with cumulative tick bites and associated illnesses over a period of years.METHODS We learned of a married couple living on a central North Carolina property who had used reasonable bite prevention methods, kept attached ticks after removal, and recorded dates and related illness records from 2001-2014...
