In the Rofental (Ötztal Alps) a consortium of the three institutions, and open to research partners worldwide, concentrates on studying and monitoring cryospheric, atmospheric and hydrological processes and changes with particular attention to the complex topography and climate settings of the Alpine terrain. First documents from glaciers in the Rofental, Ötztal Alps, date back as far as 1601 and regular observations and systematic studies had begun more than 150 years ago. First geodetic maps where generated in the late 19th century, first rain gauges were mounted in 1929 and glacier mass balance time series of Hintereis-, Vernagt- and Kesselwandferner are among the longest uninterrupted world-wide, building a basis for regional hydrological studies, for glacier-climate and ice dynamic research, and for estimating the world wide glacier’s contribution to sea level rise. By 2014, networks of stakes and pits for mass balance monitoring are maintained at Hochjoch-, Hintereis-, Kesselwand- and Vernagtferner by the consortium members. Runoff gauges at Vernagtferner and in Vent (operated by the Hydrological Office of Tyrol) and a network of rain gauges in the Rofental basin are the basis for high mountain hydrological studies. A varying number of automatic weather stations on and in the surroundings of the glaciers are operated by the Rofental consortium. The glaciers in the Rofental are frequently used as a test site for process studies, model development and evaluations and for new remote sensing or ground based methods in glaciological research. A series of airborne LIDAR derived high resolution DTMs of Hintereisferner and its surroundings are available since 2001. They are subject of ongoing evaluations and method comparison studies as well as for monitoring and studying periglacial morphodynamics. The generated data are available from the consortium partners, glaciological key results are annually reported to the World Glacier Monitoring Service (WGMS). A research station on Hintereisferner (with observer status in the Horizon 2020 INTERACT network) and one at Vernagtbach serve as logistic bases for fieldwork. In recent studies, socio-ecological research aspects – e.g. in relation with the use of water for energy production and tourism – comprise the natural scientific investigations.

The Hohes Holz is a mixed beech forest, with an intensive research site with respect to carbon and water cycle at the northern border of the Bode catchment close to Magdeburg, Germany. It is certified as class 1 ecosystem station in ICOS.

Lake Garda has the largest volume (49 billions of cubic meters) and the most extensive area (368 km2) of Italian lakes. Along with lakes Orta, Maggiore, Lugano, Como, Iseo and Idro, it forms part of the group of deep lakes located south of the Alps in one of the most densely populated and highly productive area of Italy. With a total volume of over 124 billions of cubic meters, these lakes constitute one of the largest freshwater supplies in Europe. Their waters are used for agriculture, industry, fishery and drinking. Moreover, they are an important resource for recreation and tourism thanks to both attractive landscape and water quality. In Lake Garda, sporadic studies were carried out irregularly by various Institutions up to the end of the 1980s. Since the beginning of the 1990s, continuous monthly samplings and measurements were carried out by the Department of Biology of the Padova University (Responsible, Nico Salmaso), with the collaboration of ARPAV. Since 2005 the whole limnological research is performed by the Limnological research group of the Agrarian Institute of S. Michele all’Adige – E. Mach Foundation (S. Michele all’Adige, Trento; coordinator, Nico Salmaso). Since the 1970s, Lake Garda showed an increase in the trophic status, with mean annual concentrations of total phosphorus in the whole water column increasing from ca. 10 µg P/L to 20 µg P/L. In the last 4-5 years of observations, TP showed a stabilisation of the concentrations, around 18 µg P/L. At the community level, annual phytoplankton cycles underwent a unidirectional and slow shift mainly due to changes in the species more affected by the nutrient enrichment of the lake. After a first and long period of dominance by conjugatophytes (Mougeotia) and diatoms (Fragilaria), phytoplankton biomass in recent years was sustained by cyanobacteria (Planktothrix). Other important modifications in the development of phytoplankton were superimposed on this pattern due to the effects of annual climate fluctuations principally mediated by the deep mixing events at spring overturn. Main specific research objectives in this LTER station include: -Changes in the physical, chemical and biological variables at different temporal scales, from months to decades and centuries (paleoecology). Update of the time series of hydrological, climatological and limnological data, whith special attention to lake evolution and effects on biotic communities in relation to ongoing climatic changes. Definition of predictive models. - Identification of the environmental and biotic mechanisms favouring the development of cyanobacteria (including the recent appearence of blooms and new species). Identification of the factors selecting for the development of toxic strains, the production and concentrations of epato- and neurotoxins, and their impact on trophic webs and water usability. The limnological field facilities of the limnological research group include 2 rubber dinghies, 2 multi-parameter probes, a fluoroprobe, a FlowTracker Handheld ADV Sonntek, underwater Quantum sensors, a Kajak corer and an Eckman dredge for sediment sampling. The unit also has several laboratories. These include the hydrobiology and microscopy laboratory, equipped for analyses of basic limnological variables (photosynthetic pigments, dry weight, dissolved oxygen, water turbidity, macrophytes) and of phytoplankton, picoplankton and periphyton samples (microscopes, invertoscopes, fluorescent microscopy, image analysis). The analytical and environmental chemistry laboratory is equipped for analysis of the major ions and nutrients (phosphorus, nitrogen and silica), as well as organic molecules (with focus on cyanotoxins) by means of spectrophotometry, ion chromatography and Liquid Chromatography-Mass Spectrometry (LC-MS). We have access to genetic laboratories equipped with the principal analytical tools, i.e. PCR, electrophoresis, and sequencing. The data collected at monthly frequency since 1991 includes water temperature and oxygen. Phytoplankton was collected since 1993, while complete data recording (including chemistry and zooplankton) begun in 1995.

Oulanka Research Station is part of the Infrastructure Platform and is situated in Kuusamo as a regional unit of the University of Oulu. The station is located in the Oulanka river valley within the Oulanka National Park (66°22'N, 29°19'E). The area lies within the boreal coniferous forest-zone (Taiga), where Norway spruce and Scots pine prevail. In the Oulanka river valley there are, also many alluvial meadows, stream mouths and crags supporting luxurious plant communities. The bedrock is calcium-rich in places. Bogs, fens and marshes as well as numerous springs, ponds and lakes, brooks and rivers characterize the landscapes. All these factors together create a diverse and exceptional rich environment with rich flora and fauna.In terms of temperature Oulanka has a continental climate. The coldest and warmest ever measured temperatures are -48.0°C and 32.1°C. The difference between the mean temperature of coldest (January, -15°C) and the warmest (July, 15°C) month is 30°C. The mean temperature for the whole year is c. -0.5°C (1967-2009).

Hainich is a large deciduous forest area in Thuringia and is situated in central Germany not far from the town of Eisenach with the famous Wartburg Castle. With a total area of ca. 16.000 hectares (13.000 hectares of which is forest), Hainich is the largest continuos area of deciduous forest in Germany. On the 31.12.1997 the southern part of Hainich, with an area of 7.500 hectares, was declared Germany’s 13th National Park. Since then it has been seen as a place of relaxation close to nature that is open to sustainable tourism. The area has gone through an amazing development which is quite unique. Since 2011 Hainich is part of UNESCO World Heritage Site "Primeval Beech Forests of the Carpathians and the Ancient Beech Forests of Germany".

For over 20 years as a team of Long Term Sites in Serra do Cipó PELD-CRSC has been working to answer crucial questions of evolutionary ecology and provide a basis for understanding the spatio-temporal ecosystem functioning and it is future challenges with changes in climate and land use.
