Species identity and spatial scale drive context‑dependent tree diversity effects in a Finnish forest experiment

open access: yesOikos, EarlyView.
Tree species diversity is known to affect tree growth and leaf traits, which in turn can influence various ecosystem processes. However, the reported direction of these tree diversity effects is inconsistent, indicating that their outcomes depend strongly on ecological context.

INFLUENCE OF ROOTSTOCKS AND THE TIME OF GRAFTING PROCEDURE ON THE EFFICIENCY OF PROPAGATION BY GRAFTING TWO CULTIVARS OF MOUNTAIN PINE (Pinus mugo Turra) AND ESTIMATION OF CHLOROPLAST PIGMENTS LEVEL IN THE NEEDLES

open access: yesActa Scientiarum Polonorum: Hortorum Cultus, 2020
The experimental studies were conducted from 2015–2017 years in two cycles. The aim of the research was to determine a better grafting time and a choice of an appropriate rootstock for the propagation of two cultivars of mountain pine (Pinus mugo Turra).

Unveiling human–wildlife interactions in the context of livestock grazing abandonment and the return of large carnivores, ungulates and vultures: A stakeholder perspective

open access: yesPeople and Nature, EarlyView.
Abstract Pastoral practices remain a widespread economic activity across European mountain regions. However, the viability of this activity may be threatened by the recovery of large wild vertebrates associated with passive rewilding, leading to the so‐called human–wildlife conflicts.

The potential of seedbank digital information in plant conservation

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Seedbanks are vital for biodiversity conservation, but their potential remains underutilised due to a limited understanding of the intraspecific genetic diversity they hold. By leveraging digitised data associated with seedbank collections, such as sampling locations, number of maternal plants and seed traits, we can attempt the estimation of genetic ...
