Directional turnover towards larger‐ranged plants over time and across habitats Open
Species turnover is ubiquitous. However, it remains unknown whether certain types of species are consistently gained or lost across different habitats. Here, we analysed the trajectories of 1827 plant species over time intervals of up to 7…

Comparative transcriptomic analysis reveals novel roles of transcription factors and hormones during the flowering induction and floral bud differentiation in sweet cherry trees (Prunus avium L. cv. Bing) Open
In sweet cherry trees, flowering is commercially important because the flowers, after fertilization, will generate the fruits. In P. avium, the flowering induction and flower organogensis are the first developmental steps towards flower fo…

Hierarchical drivers of soil microbial community structure variability in “Monte Perdido” Massif (Central Pyrenees) Open
Microbial activity is highly dependent on climatic factors (moisture and temperature) and edaphic characteristics in temperate ecosystems. Moreover, soil microbial community composition in high mountain areas is less known when compared to…

Nitrogen deposition and climate change have increased vascular plant species richness and altered the composition of grazed subalpine grasslands Open
Summary Atmospheric nitrogen ( N ) deposition and climate warming are two major components of global change that drive species richness and composition in plant communities. However, their combined effects have been insufficiently investig…
