Tara mountain is a part of Dinaric Alps with an average height of 1200 m above sea level and is a typical forested area located in western Serbia. Its forests are among the best preserved and most productive forests in Europe and represent the greatest natural value of Tara. The area has a temperate continental climate with subalpine influences. High humidity is caused by currents from the Drina canyon and daily mist. More than 75% of the area is covered with mixed forest of beech, fir and spruce. Tara is a well known refugium for many relict and endemic plant species among which the most valuable and recognizable is the endemic and relict Serbia spruce, Picea omorica (Pancic) Purkyně with very limited range to about only 60 ha.

Kopaonik is the largest and the longest mountain range in Serbia located in its central part. It is proclaimed a national park in 1981. The observatory site in Kopaonik is located in strictly protected spruce forest, on the lower distribution of spruce zone on the border zone with beach forest. The mountain is characterized by alternating climate conditions; from warmer sub-mediterranean climate in the lowest part of the mountain to cold subalpine climate in high elevation areas. Vertical profile of the mountain with different climate zones and geological diversity resulted in high habitat diversity. The largest part of the area is covered by climatologically adapted mixed deciduous and coniferous forest having obvious zonal transition. A large number of endemic and relict plant species makes Kopaonik one of the most significant biodiversity centers in Serbia. Main threats to the area besides soil erosion present logging, deforestation and tourism.

The Mooring B is located in the North-central Ross Sea in the Joides Basin. The mooring is equiped with sediment traps, currentometers, trasmissometer, fluorimeter and CTD. The study of mooring can be consider part of the activities conduct in the framework of the research project "ABIOCLEAR - Antarctic biogeochemical cycles - climatic and paleoclimatic reconstructions. (Resp. M. Ravaioli)". Such Project is the natural prosecution of previous research activity carried out from 1987. Objectives : Study of the particle fluxes towards the marine bottom sediment, in particular with the aim to obtain quali/quantitative estimate of the biogenica component coming from the primary production. Analysis of the vertical rain rate processes and, therefore, the marine cycle of the main biogenic particles such as Carbon and Silica. Try to obtain mass budgets of these parameters, estimating their cycle in the water column until the burial processes in sediments. From apparent accumulate rate calculated in the bottom sediment we will tried to discriminate the real vertical fluxes (Rain Rate) from the horizontal input from sediment remobilization processes. Acquisition and elaboration of long time series of data. Collection of bottom Sediment samples to estimate the variations of the productivity and the paleoproductivity in the area. Historical time series of Mooring B: Primary productivity data (every three years), fitoplancton, New and regenerated productivity, Seasonal, annual and interannual fluxes measure, monthly Particles samples, current velocity, water salinity, temperature and torbidity, Water-sediment interface measure. Biogeochemical parameters. Radiometrical Data, Mineralogical and grain size characterization. Nutrient, metals. Biostratigraphy interpretations. Lidar data are also available from 1997.

The Ross Sea is one of the two main epicontinental seas of the Antarctic continent. It is characterized by an high medium depth (ca. 500m) and by inverse slope, in fact the maximum depths are located close to the continent while the lower near the continental slope. The waters primary productivity is controlled by seasonally ice that during austral winter cover all the area, inhibiting the passage of the light and therefore precluding productivity processes. The site is a multi-site observatory constituted by four mooring sites and and the Terra Nova Bay Macro Area.

We have been monitoring Lake Kasumigaura, the second largest lake in Japan, monthly for nearly four decades. We have monitored not only environmental variables, water quality, nutrients, and heavy metals, but also plankton (e.g., bacteria, heterotrophic nanoflagellates, ciliates, picoplankton, phytoplankton, zooplankton, mysids), primary production, benthos (chironomids and oligochetes), and fish. To increase data availability and the numbers of data users, we created an English web database (http://db.cger.nies.go.jp/gem/moni-e/inter/GEMS/database/kasumi/index.html) in this research period, and strengthened our relationships with international observational networks. We also provided monitoring data to the Japan Long-Term Ecological Research Network (JaLTER; http://www.jalter.org/index.php?ml_lang=en) and published two data papers in the international journal Ecological Research (Takamura et al. 2012 a, b). We have also started to register fish monitoring data in the Global Biodiversity Information Facility (GBIF) (http://www.gbif.org/dataset/f648085b-8e1c-4a79-bc8d-f45d36296564) .

The Kellogg Biological Station (KBS) is located in southwest Michigan in the eastern portion of the U.S. cornbelt, 50 km east of Lake Michigan in the SW corner of the state (42° 24′ N, 85° 24′ W, elevation 288 m). Annual rainfall at KBS averages 1,005 mm/y with about half falling as snow; potential evapotranspiration (PET) exceeds precipitation for about 4 months of the year. Mean annual temperature is 10.1 °C. KBS is 1600 ha of cropping systems, successional communities, and small lakes. Surrounding KBS is a diverse, rural-to-semirural landscape typical of the U.S. Great Lakes and upper Midwest regions. The diversity of land use, soil and vegetation types, and aquatic habitats within a 50-km radius of the Station is high. Most of southwest Michigan is on the pitted outwash plain of the morainic system left by the last retreat of the Wisconsin glaciation, circa 12,000 years ago. Soils in the area developed on glacial till, and include well- and poorly-drained alfisols, mollisols, and entisols. Most regional soils are sandy loam and silty clay loam of moderate fertility, principal Station soils are Typic Hapludalfs. Land use around KBS ranges from urban (Kalamazoo, with a metropolitan population of 180,000, is 20 km south of the Station) to rural; vegetation ranges from cultivated and early successional old fields to older growth oak-hickory and beech-maple forests; and aquatic habitats include more than 200 bodies of water of different morphometries, alkalinities, and degrees of eutrophication within 50 km. Cropping systems in the area are typical of the U.S. cornbelt — mainly corn/soybean rotations with wheat of varying importance, and alfalfa an important forage crop. KBS yields are typical of non-irrigated yields elsewhere in the North Central Region. KBS LTER research is carried out in a variety of experimental systems. The most important of these is the Main Cropping System Experiment (MCSE), which was started in 1989 and consists of 11 different cropping systems or successional plant communities, ranging from annual corn-soybean-wheat rotations to late-successional deciduous forest. All communities are replicated within the landscape.

Sokolov post-mining ecosystems represent a unique LTER study area comprising forest and non-forest ecosystems developing after reclamation or by spontaneous revegetation on heaped overburden from brown coal mining. Several 1 ha sites are studied since 1992 (10 sites intensively and over 50 sites occasionally). Research has been focused on interactions between soil, plants and soil organisms and their role in soil formation and biogeochemical cycles restoration. Great attention has been paid to comparison of long-term development of reclaimed and non-reclaimed sites and to the effect of different tree species, types of substrates and heaping technique used during reclamation. Series of sites of known age (15–70 years) developing on similar substrate represent a great opportunity for ecological research using a chronosequence approach.

Ashiu Forest Research Station is located in the northeastern border part of Kyoto Prefecture in main island Honshu and stretches 6km east to west and 7km north to south in a rectangular shape. The area is characterized by high relief with altitudes ranging from 355 to 959 m above the sea level and encompasses the headwater zones of Yura River flowing into Wakasa bay, the Sea of Japan. This region is situated in the transition part between cool temperate forests and warm temperate forests. There is a heavy snowfall ranging from 1 to 3m in winter seasons. More than half of Ashiu Forest Research Station is covered with old-growth forests. In cool temperate forests above 600m altitude, the main species are beech (Fagus crenata), Japanese ceder (Cryptomeria japonica), deciduous oak (Quercus crispula). In warm temperate forests under 600m altitude, evergreen and deciduous oaks (Quercus salicina and Quercus sessilifolia) can be seen. There are two noteworthy characteristics in Ashiu Forest Research Station. Firstly, its high biodiversity. Since the establishment of the Research Station in 1921, new plant or vertebrate species/ varieties have been found. 801 woody, herbaceous and fern species have been recorded (Yasuda and Nagamasu 1995). Nationally protected species such as Japanese serow (Capricornis crispus) and Giant Saramander (Andrias japonicas) can be seen. Secondly, Ashiu Forest Research Station has been used not only for research and education but also for ecotourism by local stakeholders for more than 20 years, which has great opportunities for inter- and transdisciplinary studies.

Pianosa Island (Long. 10° 04' 44” E and Lat. 42° 35' 07” N) is the fifth, by extension, of the seven islands of the Tuscan Archipelago National Park with a total area of 10.2 km2 and a coastal perimeter of approximately 20 km. The island is almost completely flat, with some small undulations. The highest elevation is 29 m above sea level (a.s.l.), while the average is about 18 m a.s.l. The climate of Pianosa is influenced by its flat morphology that prevents the condensation of moist air, resulting in a mean annual rainfall considerably lower than on the other islands of the Tuscan Archipelago; furthermore, due to the high permeability of the soils, the rain is quickly drained. On the basis of an historical meteorological dataset (1951-2009), mean air temperature is 15.8 °C and mean annual rainfall is 497 mm, ranging between a minimum of 176 mm (1999) and a maximum of 716.2 mm (1984). A clear seasonal precipitation pattern shows a maximum from October to December followed by a decrease with a minimum value in July. The first historical record of Pianosa island dates back to the Roman age, when the Emperor Ottaviano, in the 6-7 A.C., forced the grandson Agrippa Postumo to live on Pianosa island. Following the decadence of the Roman Empire, during the periods of Barbarians’ invasions, the island was abandoned. The name of Pianosa island newly appeared in some documents of the Repubbliche Marinare of Pisa and Genova (XII and XIII century) that reported the remarkable strategic position of the island. The 27th August 1802, Napoleone Bonaparte established that the islands of Elba, Capraia, Pianosa, Palmaiola and Montecristo were united to the territory of the French Republic. Bonaparte visited Pianosa twice and found it the most interesting of the other islands, appreciating its richness of vegetation and animals. In 1858 Pianosa became an Agriculture Penal Colony, where the prisoners were forced to work in the fields. During the ’70s the jail of Pianosa became a maximum security penitentiary. Only in the ’80s, representatives of the Government and members of the civil society started to propose to close the prison and to return Pianosa to the competent civil authority. In view of this, the number of the prisoners was drastically reduced and, consequently, several agriculture activities progressively stopped. In the 1997 the territory of Pianosa was formally included in the National Park of the Tuscan Archipelago and since than it is a site for natural conservation. In 1998 the penitentiary was completely dismissed
