Petrocodon gracilis (Gesneriaceae) is a synonym of P. mirus based on morphological and molecular data

open access: yesNordic Journal of Botany, EarlyView.
Petrocodon gracilis T.Ding & B.Pan and P. mirus X.Z.Shi, J.X.Fu & Li H.Yang are two recently described species exhibiting nearly identical morphology. To determine whether they represent the same taxon, we compared their type localities, type materials, and morphological features and conducted phylogenetic analyses using the nuclear internal ...

Aster tongrenensis (Asteraceae), a remarkable new species from Guizhou, China

open access: yesNordic Journal of Botany, EarlyView.
Aster tongrenensis (Asteraceae), a remarkable new species from Guizhou, China, is here described, illustrated and compared with related taxa based on integrated evidence from morphology, micromorphology and molecular phylogeny. Morphological and micromorphological observations indicate that A. tongrenensis is most similar to A.

Whole‐seedling trait adjustments of mountain birch under contrasting environmental conditions

open access: yesOikos, EarlyView.
Warming temperatures can promote arctic tree seedling establishment and growth, but these effects depend on the environmental context and the seedlings' capacity to acquire limiting resources. Here, we tested how temperature, soil properties, and the presence of a neighbouring shrub influence seedling growth rates.

Why do people go to nature? Enhancing the recognition and scope of cultural ecosystem services in landscape

open access: yesPeople and Nature, EarlyView.
Abstract The cultural ecosystem services (CES) framework allows to systematically analyse non‐material human–nature relationships and can help to increase the recognition and scope of various intangible place‐based values. Although the amount of scientific literature addressing CES has increased over the last few decades, studies largely focus only on ...

Simulated elephant foraging alters tree root exudation rates: Species‐specific responses and implications for belowground carbon dynamics in tropical forests

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Asian elephants play crucial roles in ecosystem functioning, and their interactions with plants influence above‐ and belowground carbon cycling. We tested whether their mechanically destructive foraging triggers short‐term, stress‐induced shifts in tree root exudation, an underappreciated pathway linking herbivory to belowground carbon processes.
