Assessment of the effects of biophysical and anthropogenic factors on woody plant encroachment in dense and sparse mountain grasslands based on remote sensing data
TL;DR: In this paper, the authors assessed woody plant encroachment in mountain grasslands in many regions of the world and found that land abandonment exacerbated by climate change has led to increased woody plants encroachment of mountain grassland.

No shift to a deeper water uptake depth in response to summer drought of two lowland and sub-alpine C3-grasslands in Switzerland
Ulrich E. Prechsl,Susanne Burri,Susanne Burri,Anna Katarina Gilgen,Anna Katarina Gilgen,Ansgar Kahmen,Nina Buchmann +6 more
TL;DR: It is shown that the drought treatment in the two grasslands did not induce a shift to deeper uptake depths, but rather continued or shifted water uptake to even more shallower soil depths, illustrating the importance of shallow soil depths for plant performance under drought conditions.
Journal ArticleDOI
Intensity and timing of warming and drought differentially affect growth patterns of co-occurring Mediterranean tree species
Elena Granda,J. Julio Camarero,J. Julio Camarero,Teresa E. Gimeno,Teresa E. Gimeno,Jesús Martínez-Fernández,Fernando Valladares,Fernando Valladares +7 more
TL;DR: It is concluded that the seasonal timing of warming and precipitation alterations leading to drought events caused contrasting effects on growth of co-occurring Mediterranean tree species, compromising their future coexistence.
Journal ArticleDOI
Multi-scale environmental heterogeneity as a predictor of plant species richness
TL;DR: In this paper, the authors used a statistical modeling approach to determine which metrics of heterogene-ity measured at which scales were useful predictors of local species richness, and whether the heterogeneity-local richness relationship was always positive.

Bears and berries: species-specific selective foraging on a patchily distributed food resource in a human-altered landscape.
Anne G. Hertel,Sam M. J. G. Steyaert,Andreas Zedrosser,Atle Mysterud,Hanna Kavli Lodberg-Holm,Henriette Wathne Gelink,Jonas Kindberg,Jon E. Swenson +7 more
TL;DR: It is shown that bears are successful in navigating human-shaped forest landscapes by using areas of higher than average berry abundance in a period when abundant food intake is particularly important to increase body mass prior to hibernation.
