Transformative changes of pastoral livestock production and its consequences on the Qinghai–Xizang Plateau

open access: yesGrassland Research, EarlyView.
Grassland functional zoning and spatial optimization scheme on the Qinghai–Xizang Plateau. Based on multifunctionality assessment, the scheme proposes allocating 32% of regional grassland as nature reserve grasslands (biodiversity focus), 63% as livestock grazing grasslands (smart ecological–production management), and 5% as cultivated grasslands (high‐

Diterpenoid Diversity across Land Plants

open access: yesHelvetica Chimica Acta, EarlyView.
Here we bridge the knowledge of diterpene chemical diversity, biosynthesis, and evolution from nonvascular mosses and liverworts to that known from vascular plants. ABSTRACT The diverse array of diterpenoid natural products stems from the ease of manipulating the promiscuity of diterpene cyclases.

Butterfly and moth habitat specialisation changes along an elevational gradient of tropical forests on Mount Cameroon

open access: yesOikos, EarlyView.
Niche breadth, reflecting the range of environmental conditions or resources a species can exploit, influences its distribution, persistence, vulnerability to environmental change, and interspecific interactions. The elevational niche‐breadth hypothesis predicts broader ecological niches at higher elevations due to increased environmental stress and ...
