Fine-scale climate information is critical to understand species–climate relationships. It is usually obtained by interpolating meteorological station data or by downscaling coarse-gridded climate data. In mountain areas, however, the low station density and macroclimate variables used in coarse-gridded climate products cannot reproduce fine-scale...

Natural and artificial lakes provide multiple cultural ecosystem services (CES), but they are largely underrep-resented in CES assessments, which mostly focus on individual large lakes. Social media data may offer an opportunity to analyse CES of lakes at regional scales. This study therefore aims at exploring the use of photos uploaded to the phot...
Article
Globally, mountain areas are facing numerous social, economic, and ecological challenges. The interplay of natural and social factors makes them complex social-ecological systems. To investigate a mountain setting in the Austrian Alps, we developed the resilient livelihood framework (RLF), relying on the sustainable livelihood framework and integra...

Grassland ecosystems provide the basis for grassland farming where climate and topography constrain the cultivation of crops. Current agricultural systems and their nutrient cycles are out of balance, due to the segregation of feed provision and consumption. However, knowledge on interlinkages between feed supply and demand is scarce and remains un...
Article
In the last 100 years, climate warming has been affecting the European Alps faster and more severely than globally observed temperature patterns. Temperature changes are known to affect soil properties and microbial community structures, and land-use change in Europe is an expected socio-economic consequence of climate change. However, few studies...

The Alps are the highest and largest mountain range in Europe. They extend from the Ligurian Sea to the Pannonian Basin in an arc 744 miles (1,200 km) long and between 93 and 155 miles (150–250 km) wide. The settlement history of this large European landscape is closely linked to the settlement of Europe as a whole, whereby the inner Alpine region...

The concept of ecosystem services (ES) differentiates between supply, flow and demand. ES supply is usually defined as the capacity of ecosystems to provide an ES regardless of this being actually used, whereas ES flow refers to the actual level of use. Demand for ES represents the amount of a service required or desired by society. Hence, the quan...
