Alpha, beta and gamma diversity in relatively natural, mixed and transformed landscape scenarios

open access: yesEcography, EarlyView.
Biodiversity losses and biotic homogenisation associated with human‐induced land‐cover changes are key issues for ecology. However, the effects of human‐caused land‐use changes on biodiversity change at the landscape scale are not well understood. Combining the PREDICTS global biodiversity database with MODIS satellite‐based land cover from 2001 to ...

Carbonylative Suzuki–Miyaura Coupling of 1‐Iodoglycals Mediated by the N‐Heterocyclic Carbene Catalyst PEPPSI: Preparation of C‐Acyl Glycosides

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A multicomponent carbonylative Suzuki–Miyaura reaction was developed for the synthesis of C‐acyl glycosides. Using Pyridine‐Enhanced Precatalyst Preparation, Stabilization, and Initiation (PEPPSI‐IPr) catalysis and Mo(CO)6 as a solid CO source, the reaction enables selective carbonylation of three components in synthetically useful yields, providing a ...

First Confirmed Cooperative Breeding of the Brown Hornbill (Anorrhinus austeni) in China at the Sino–Lao Frontier 中国中老边境尚勇保护区首次记录白喉犀鸟 (Anorrhinus austeni) 的合作繁殖行为

open access: yesIntegrative Conservation, EarlyView.
First confirmed breeding of the Brown Hornbill in China, documented through cooperative feeding in Shangyong Protected Area. ABSTRACT The Brown Hornbill (Anorrhinus austeni), a Near Threatened frugivore, reaches the northern edge of its distribution in southern Yunnan, China, yet breeding had not been previously documented with site‐attributed nests in

How competitive is drought deciduousness in tropical forests? A combined eco-hydrological and eco-evolutionary approach

open access: yesEnvironmental Research Letters, 2017
Drought-deciduous and evergreen species are both common in tropical forests, where there is the need to cope with water shortages during periodic dry spells and over the course of the dry season. Which phenological strategy is favored depends on the long-
