Nitrogen enrichment drives accelerative effect of soil heterogeneity on the flowering phenology of a dominant grass Open
Plant phenology is affected by both abiotic conditions (i.e., temperature, nitrogen enrichment, and drought) and biotic conditions (i.e., species diversity). The degree of spatial heterogeneity in soil resources is known to influence commu…

Reciprocal transplant gardens as gold standard to detect local adaptation in grassland species: New opportunities moving into the 21st century Open
Local adaptation is a fundamental phenomenon in evolutionary biology, with relevance to formation of ecotypes, and ultimately new species, and application to restoration and species’ response to climate change. Reciprocal transplant garden…
