The site corresponds to the territory of Gran Paradiso National Park. This includes different ecosystems, present along the altitudinal gradient (ca. 800 – 4000 m asl): the woody areas of the montane belt, the ecotonal habitats of the subalpine belt and the meadows of the alpine one. The nival belt is widely represented inside the Park. The habitats with poor or no vegetation (rocks, screes, glaciers) cover about 60% of the territory, meadows and pastures 17%, about 20.2% is characterised by woods and shrubs, while 0.8% by cultivated lands and urban areas. The aquatic ecosystems, beyond the streams, comprise almost 15 lakes, bigger than 10,000 m2 and located at an altitude higher than 2000 m asl. The area is directly managed by the Park Authority; research and monitoring activities are coordinated by the Sanitary and Scientific Office of the Park.

How do freshwater ecosystems react to changing environmental conditions and to what extent can these changes be captured in the dynamics of eco-evolutionary processes? The project REES ('Rhine Eco-Evolutionary System') aims at the long-term assessment of eco-evolutionary interactions in the Rhine as a limnic habitat under consideration of diverse associated water bodies. The study area includes the main flow channel of the Rhine (km 845, North Rhine-Westphalia), as well as Rhine oxbows, Rhine water-fed gravel pit lakes in ecological succession and the surrounding floodplain (Rees, district of Kleve). The Ecological Research Station Rees-Grietherbusch of the Institute of Zoology (University of Cologne) and the Nature Conservation Center District Kleve e.V. form the central infrastructure of the study area. In addition, the Ecological Rhine Station of the University under the direction of Prof. Dr. Arndt is also associated to the project, which enables direct sampling and experimental recording of the main Rhine flow channel. The extensive system of standing and flowing freshwater bodies covered in the REES study site allows the investigation of dynamic variations in biodiversity composition at all levels, from species diversity of communities to genomic diversity at the molecular level of individuals and populations. Along a selected trophic cascade, representative species will be long-term observed and analyzed ecologically and especially also (population-)genomically. The incorporation of ecological genomics is the core aspect of this LTER-D project, which is intended to capture the feedback of evolutionary changes on the ecological system. Population genomic approaches can be used to infer both evolutionary and ecological processes from genomic data. To cope with the dimension of this project, REES is designed as an interdisciplinary collaboration project and currently counts seven project partners with corresponding subordinate projects.

The LTSER Zone Antarctique belongs to LTER-France network and is located in Antarctica (Adelie Land), French sub-Antarctic Islands (Crozet archipelago, Kerguelen Islands, Saint-Paul et Amsterdam Islands) and southern ocean. General information below concerns Kerguelen Islands. The ZATA measures the impacts of climate change and human activities on antarctic and sub-antarctic ecosystems.

The site is a revitalized young steppe habitat patch, dominated by fescue (Festuca rupicola). The average altitude is around 100 m. The site is a grazing spot and it was recently used for the reintroduction of the European ground squirrel (Spermophilus citellus) to the area after 70 years. Other important species present at the site include Vojvodina blind mole rat (Nannospalax (leucodon) montanosyrmiensis) and Spring meadow saffron (Bulbocodium versicolor).

The Presidential Estate of Castelporziano stretches itself over an area of about 6100 ha and is located approximately 24 km from the city of Rome. The territory is characterized by remarkable natural features. It shows most of the typical Mediterranean ecosystems (relict strips of lowland forest with hygrophilous vegetation, deciduous and evergreen mixed oak woods, Mediterranean scrub, dune vegetation). Until recently (2019), there were large surfaces of stone pine unfortunately destroyed by the combined action of alien pest Toumeyella parvicornis with Tomicus destruens, the main pest of Mediterranean pine forests. Inside the Estate, there are two Special Areas of Conservation (SACs): one concerning the coastal strip (IT6030027) and the other one concerning hygrophulous oak-woods (IT6030028). In addition to including the two SACs, the Estate is in its entirety Special Protection Area (SPA - IT 6030084). From a botanical point of view this area, together with the neighbouring Castelfusano territory, represents what remains of the vast forest system that covered the entire delta of the Tiber and the surrounding areas. The land is mostly flat, but in the North there are modest reliefs that are not higher than 85 m. on sea level. A complex set of ancient dunes and a chain of more recent dunes stretch out along the coastline. There are many temporary and permanent natural pools and wetland areas with seasonal floodings caused by meteoric water and groundwater, which usually dry out during summer and represent sites with the greatest biodiversity. From an ecological point of view, those “relict wetland areas” play actually a very important role for biodiversity because of plant species which are typical of hydrosoil and in the past were widespread but have now almost disappeared.

The Archipelago Research Institute is a historical marine station at the island of Seili, located in the middle of the Turku archipelago. The Institute offers various research support services as well as participates in multidisciplinary research of the Baltic Sea, with a special focus on the condition of the Archipelago Sea. The station is open for researchers and visitors year-round.

Lake Orta is a deep subalpine lake, located in Northern Italy, at a mean altitude of 290 m a.s.l. Its perimeter is 33,8 km, surface area 18,14 km2, volume 1,29 km3. Lake Orta has a maximum depth of 143 m and a mean depth of 71 m. Lake Orta is well known for being polluted by industrial discharges (copper sulphate and ammonia) since the late 1920: as a consequence, the pH of the lake water dropped down till 4 and the food web was almost completely destroyed, except for some few, strongly adapted species. The pollution stopped around mid 1980s and a liming intervention was carried out in 1989-1990, to neutralize the acidic waters of the lake. The recovery was very fast, new species started to colonise the lake just after the liming. The lake, however, is still at risk, due to the large amount of heavy metals stored in the sediments.

The Kinneret Limnological Laboratory (KLL) is situated at the ‘Sapir’ Site (Tabha) on the shores of Lake Kinneret (Sea of Galilee). The Lake Kinneret monitoring program conducted by KLL has been operating since Jan. 1969. The program has provided a unique database and information, due to the sampling resolution, accuracy of the measurements, and their continuity, it is used to make operational decisions and environmental policy. The monitoring program includes several stations around the lake and from numerous depths and includes fixed on-lake, high-resolution, and manual sampling of water samples analyzed in the laboratory. The Kinneret monitoring program has expanded in recent years and currently has four fixed on-lake and online sampling platforms, strategically placed, each with thermistor chains and multi-probe sensor systems including one that is a profiling system. Also, the program includes collaboration with the Ministry of Agriculture to carry out monitoring of fish and fisheries in the lake. As the lake suffers typically from two seasonal cyanobacteria blooms, (i.e., a winter Microcystis bloom and a summer N-fixing cyanobacteria bloom) routing monitoring of cyanobacteria biomass and toxins is conducted and adaptive to the extent of the bloom. This is carried out simultaneously with satellite imaging over the lake.
