According to the stress gradient hypothesis (SGH), ecological interactions between
organisms shift positively as environmental stress increases. In the case of associational …

Abstract The Qinghai–Tibet Plateau (QTP) is the highest and largest plateau in the world. It
covers correspondingly wide geological, topographical, and climatic gradients, and thus …

Interactions among species determine local‐scale diversity, but local interactions are
thought to have minor effects at larger scales. However, quantitative comparisons of the …

New evidence demonstrates that facilitation plays a crucial role even at the edge of life in
Maritime Antarctica. These findings are interpreted as support for the stress‐gradient …

Previous syntheses on the effects of environmental conditions on the outcome of plant–plant
interactions summarize results from pairwise studies. However, the upscaling to the …

A rapid warming in Himalayas is predicted to increase plant upper distributional limits,
vegetation cover and abundance of species adapted to warmer climate. We explored these …

Abstract Background and Aims The stress gradient hypothesis (SGH), the view that
competition prevails in undisturbed and productive environments, and shifts to facilitation in …

Question Species–specific interactions can connect particular species to others, which has
important implications for species interdependence and co‐existence. However, species …

Positive interactions have started to gain a place as important drivers of community structure
and biological diversity. Defined as non‐trophic interspecific interactions that increase the …

Microorganisms play a crucial role in biogeochemical cycles and ecosystem processes, but
the key factors driving microbial community structure are poorly understood, particularly in …
