Recurrent drought amplifies drought impacts and increases seasonal synchrony in mountain grassland communities

open access: yesOikos, EarlyView.
Climate change increases the recurrence of drought events with strong repercussions on grassland ecosystems. While the effects of single drought events on ecosystem structure and functioning are well understood, it is largely unknown whether and how recurrent drought events modify ecosystem responses to subsequent drought.

Forbs in Viking lands: the effect of disturbing dominant graminoids on recruitment in tundra grasslands

open access: yesOikos, EarlyView.
Grasslands, by definition, are dominated by graminoids. Nevertheless, forbs also make up a substantial part of vascular plant diversity in grasslands and are important resources of mammalian herbivores. However, forb recruitment is constrained by successful dominant graminoids, limiting access to safe sites for germination.

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.

Aromatic plants, nest bacterial diversity, and nestling condition in Corsican blue tits

open access: yesOikos, EarlyView.
According to the ‘nest protection hypothesis', some passerines incorporate fresh aromatic plants into their nests which reduce pathogens that can negatively affect nestlings. We experimentally evaluated the effect of five aromatic plant species on the nest bacterial microbiota of Corsican blue tits Cyanistes caeruleus.
