Traditional versus sprinkler irrigation of mountain hay meadows in the Valais : consequences for biodiversity [PDF]

open access: yes, 2015
Semi-natural grasslands including hay meadows belong to the most species-rich habitats in central Europe and are therefore of high conservation value. The high biodiversity of these grasslands has been maintained for many centuries through the regular ...

Building mountain biodiversity: Geological and evolutionary processes [PDF]

open access: yesScience, 2019
Mountain regions are unusually biodiverse, with rich aggregations of small-ranged species that form centers of endemism. Mountains play an array of roles for Earth’s biodiversity and affect neighboring lowlands through biotic interchange, changes in regional climate, and nutrient runoff. The high biodiversity of certain mountains reflects the interplay

Quantitative Identification of Antioxidant Basis for Dendrobium Nobile Flower by High Performance Liquid Chromatography-Tandem Mass Spectrometry

open access: yesInternational Journal of Analytical Chemistry, 2022
Dendrobium nobile is a beautiful orchid and a widely used medicinal plant. In vitro antioxidant assays suggested that D. noblie flower extracts showed significantly higher 2, 2′-azinobis-3-ethylbenzthiazoline-6-sulfonate (ABTS) and 1, 1-diphenyl-2 ...

Mountain Biodiversity in Romania

open access: yesGrassroots Journal of Natural Resources, 2023
There exists a strong link between mountain regions and biodiversity. These regions represent the most important source of regional and global ecosystems forming the core elements of environmental and sustainable development policies. Mountains operate as true refuge for endemic species but are affected by uncontrolled human actions, while alpine ...

Irrecoverable carbon in mountains and the global mitigation potential of agroforestry and increased tree cover in mountain agricultural systems

open access: yesCircular Agricultural Systems, 2023
Agroforestry has many benefits suited to mountain agricultural systems. This paper seeks to understand and quantify the mitigation potential of multifunctional agroforestry systems, and the potential for increased tree cover in mountains.

Mountain biodiversity and elevational gradients [PDF]

open access: yesFrontiers of Biogeography, 2021
Mountains are excellent systems for studying species responses to changing conditions because climatic conditions and related productivity measures change rapidly over short distances (Korner 2007).  Mountains also often have high biodiversity and high levels of endemism (Hoorn et al. 2018, Rahbek et al.

Mountain biodiversity in Brazil [PDF]

open access: yesRevista Brasileira de Botânica, 2007
The high species richness and diversity found in tropical montane habitats are often related to: 1) an effect of climatic and geological history on biotic evolution; 2) the various environmental impacts on species adaptation mechanisms; and 3) the continuous dispersal of fauna and flora in time.

Why mountains matter for biodiversity [PDF]

open access: yesJournal of Biogeography, 2019
Mountains are arguably Earth’s most striking features. They play a major role in determining global and regional climates, are the source of most rivers, act as cradles, barriers and bridges for species, and are crucial for the survival and sustainability of many human societies. The complexity of mountains is tightly associated with high biodiversity,
