Increasing anthropogenic pressures on forests, especially in the tropical regions of the world, have restricted several large mammalian species such as the Asian elephant to fragmented habitats within human-dominated landscapes. In this study, we assessed the effects of an anthropogenic landscape and its associated conflict with humans on the physiological stress responses displayed by Asian elephants in the Anamalai Hills of the Western Ghats mountains in south India. We have quantified faecal glucocorticoid metabolite (FGM) concentrations in focal individual elephants within and across herds, inhabiting both anthropogenic and natural habitats, and evaluated their physiological responses to different socio-ecological situations between November 2013 and April 2014...

Thomas M Onuferko
Herein, the cleptoparasitic (cuckoo) bee genus Epeolus (Hymenoptera: Apidae) is revised for species occurring in North America, north of Mexico, and an updated checklist of all species known to occur in Canada and the United States of America is provided with comprehensive descriptions, diagnoses, and a single dichotomous key (using the same couplets for both sexes) to aid in their identification. To increase their recognition among North American naturalists, English common names are also proposed for all North American Epeolus ...

Infection experiments are critical for understanding wildlife disease dynamics. Although infection experiments are typically designed to reduce complexity, disease outcomes still result from complex interactions between host, pathogen, and environmental factors. Cryptic variation across factors can lead to decreased repeatability of infection experiments within and between research groups and hinder research progress. Furthermore, studies with unexpected results are often relegated to the "file drawer" and potential insights gained from these experimental outcomes are lost...

The Sumatran rhinoceros (Dicerorhinus sumatrensis), once widespread across Southeast Asia, now consists of as few as 30 individuals within Sumatra and Borneo. To aid in conservation planning, we sequenced 218 bp of control region mitochondrial (mt) DNA, identifying 17 distinct mitochondrial haplotypes across modern (N = 13) and museum (N = 26) samples. Museum specimens from Laos and Myanmar had divergent mtDNA, consistent with the placement of western mainland rhinos into the distinct subspecies D. s. lasiotis (presumed extinct)...

Background: Emergency preparedness at all levels (individuals and communities) is the corner stone of effective response to the increasing trends of global disasters due to man-made and natural hazards. It is determined by different factors, including (among others) past direct and indirect exposures to hazards. This study was carried out in Dire Dawa town, Ethiopia, which in the past experienced frequent flooding events, yet dearth of information exists about preparedness in the area...

BACKGROUND: This study is focused on a rapid and safe transfer when there are many people who need rescuing in unapproachable location. Generally, a stretcher, a basket or a mesh drawing is used to transfer injured people or survivors in the emergency rescue, however, it turned out that it takes long time to transfer a number of people with a stretcher and it is difficult to transfer injured people safely with a basket or a mesh drawing. It would expect to transfer many people who need rescuing promptly and harmlessly...

Jacobus H Visser, Nigel C Bennett, Bettine Jansen van Vuuren
The subterranean niche harbours animals with extreme adaptations. These adaptations decrease the vagility of taxa and, along with other behavioural adaptations, often result in isolated populations characterized by small effective population sizes, high inbreeding, population bottlenecks, genetic drift and consequently, high spatial genetic structure. Although information is available for some species, estimates of genetic diversity and whether this variation is spatially structured, is lacking for the Cape mole-rat (Georychus capensis)...

Plant meristems were previously thought to be sterile. Today, meristem-associated shoot endophytes are mainly reported as contaminants from plant tissue cultures, the number of observed species being very low. However, the few strains characterized have the capacity for infecting host cells and affecting plant growth and development. Here we studied the communities of endophytic bacteria in the buds of mountain birch (Betula pubescens ssp. czerepanovii (N. I. Orlova) Hämet-Ahti) exposed to winter moth (Operophtera brumata L...

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)...
