Research has shown that some plants respond to enhanced UV-B radiation by producing smaller and thicker leaves, by increasing the thickness of epidermis and concentration of UV-B absorbing compounds of their surface layers and activation of the antioxidant defence system. The response of high-altitude plants to UV-B radiation in controlled conditions is often less pronounced compared to low-alt...

Alpine plants offer unique opportunities to study the processes and economics of nutrient storage. The short alpine growing season forces rapid completion of plant growth cycles, which in turn causes competition between vegetative and reproductive growth sinks during the early part of the growing season. Mobilization of stored nitrogen and carbon reserves facilitates competing sinks and permits...

BACKGROUND Gardeners and park managers seeking to support biodiversity in urban areas often plant ornamentals attractive to flower-visiting insects. There is a huge diversity of garden plant varieties, and some recommendations are available as to which are attractive to insects. However, these are largely not based on rigorous empirical data. An important factor in consumer choice is the range ...

Water and phosphorus (P) are two critical resources for high nature value farming in semi-dry mountains. ey are major drivers of grassland productivity but can negatively a€ect plant diversity. Soil moisture is known to a€ect soil microbial activity and plant P nutrition but the e€ects of irrigation on soil P status, soil microbial P and plant P nutrition in semi-natural grasslands remain larg...

As a consequence of climate warming, species usually shift their distribution towards higher latitudes or altitudes. Yet, it is unclear how different taxonomic groups may respond to climate warming over larger altitudinal ranges. Here, we used data from the national biodiversity monitoring program of Switzerland, collected over an altitudinal range of 2500 m. Within the short period of eight ye...
