Climatic extreme events can cause the shift or disruption of plant-insect interactions due to altered plant quality, e.g. leaf carbon to nitrogen ratios, and phenology. However, the response of plant-herbivore interactions to extreme events and climatic gradients has been rarely studied, although climatic extremes will increase in frequency and intensity in the future and insect herbivores repr...

Plants in high-altitude habitats are exposed to severe environmental stressors, including extreme temperatures and irradiation, which can have wide-ranging effects on changes of secondary-metabolite profiles higher plants. Altitude-related variation levels polyphenols organs medicinal food plant species has not yet been investigated sufficiently. This study was focused quantitative classes indi...

Chinese snub-nosed monkeys belong to the genus Rhinopithecus and are limited in distribution to six isolated mountainous areas in the temperate regions of Central and Southwest China. Compared to the other members of the subfamily Colobinae (or leaf-eating monkeys), these endangered primates are unique in being adapted to a high altitude environment and display a remarkable ability to tolerate ...

BACKGROUND Psychotic episodes during exposure to very high or extreme altitude have been frequently reported in mountain literature, but not systematically analysed and acknowledged as a distinct clinical entity. METHODS Episodes reported above 3500 m altitude with possible psychosis were collected from the lay literature and provide the basis for this observational study. Dimensional criteri...

The lung is the interface between the environment and the metabolic mechanisms of the body, and plays a pivotal role in exposure to high altitude. In fact, high altitude is a challenge for the human body due to the progressive reduction of barometric pressure and subsequent reduction of oxygen pressure, leading to a series of important physiologic responses that enable individuals to tolerate h...
