Dataset provides ammonia concentrations measured in Lake Santo Parmense during the period 2007-2010. Water samples were collected by means of a Ruttner bottle at different depths over the whole water column at the point of maximum depth of the lake. Samples were analysed spectrophotometrically according to Koroleff (1970).

Dataset provides water temperature measured in Lake Santo Parmense in period july 1971 - october 1975. Temperature was measured at different depths over the whole water column at the point of maximum depth of the lake.

Dataset provides dissolved reactive phosphorus concentrations measured in Lake Santo Parmense between may 2007 and october 2010. Water samples were collected by means of a Ruttner bottle at different depths over the whole water column at the point of maximum depth of the lake. Samples were analysed according to APHA, AWWA, WPCF (1971).

Dataset provides information about reactive silica (in mg Si L-1) in Lake Paione Inferiore (LPI) at different layer depths along the water column within the period 1984-2013. Data are at least biannual (late summer/autumn). In total 279 records of reactive silica in the Lake for the period are uploaded. The range is from 0.065 to 1.39 mg Si L-1 (±0.153). Lake Paione Inferiore is a high altitude Alpine lake, located in the Bognanco Valley, Province of Verbania, Piedmont Region, Italy. It has a surface area of 0.86 ha and a maximum depth of 13.5 m. The Lake is included in the monitoring sites of the UN-ECE Program ICP WATERS (International Cooperative Programme on Assessment and Monitoring of Acidification of Rivers and Lakes)

In this project we monitor temporal trends in bird communities in a high-altitude birch-dominated habitat in Central Norway. The project aims to monitor both community composition and changes in territory size among and within species in the study period. The study started in 1967 and is still on-going. Methods: Standardized transects are monitored 10 timed in early parts of the breeding season, following a GPS-track of 3km. Bird species and numbers are noted and placed relative in the habitat. This is done to potentially estimate territory size, which is performed by standardized formulas annually. Both seen and heard individuals are noted.

Dataset provides soluble reactive phosphorus (SRP) concentrations measured in Lake Santo Parmense during the period 1953-1954. Water samples for SRP analysis were collected only from the surface layer at the point of maximum depth of the lake. No information on the analytical method used is available.
