Overview

Detailed view

Monthly measurement of soil temperature and soil gas fluxes (CO2, N2O) in the NUMEX plots in Bombuscaro, ECSF und Cajanuma

Monthly measurements of gas fluxes were performed using static vented chambers.
Soil temperature was taken simultaneously with gas measurements.

Arbuscular mycorrhizal root colonization (%), colonized root length (cm/cm³) and fine root parameters in response to nutrient additions (N, P and NP) are reported. Samples were taken in October 2010 at the NUMEX plots at 2000m.

AMF root colonization of roots extracted from the upper soil layer (5cm) at all NUMEX plots. Roots are stained with Trypan Blue, AMF root colonization is examined by the line-intersect method.

Weekly time series of measured concentrations of Al, Mn, Zn, Cl, PO4-P, Total P, NH4-N, NO3-N, Total N, S, K, Na, Mg, Ca and Total organic C in throughfall in the ECSF area in the microcatchment Q2 (transects Q2.1, Q2.2 and Q2.3). The weekly time series extends between March 1998 and May 2013. Throughfall was sampled with 20 Hellmann-type collectors per transect. Replicates were collected, volume-weighted and bulked to one sample per transect and collecting interval. Samples were immediately filtered (4-7 µm) in the laboratory of the ECSF and stored at -20 °C until transport in frozen state to Germany or to Switzerland for concentration measurements.

Position of trees in the natural forest experiment was calculated using trigonometric measurements from 2004 and 2009. Precision is estimated to be between 0-10m.

Ongoing data collected from ECSF Thies climate station.

Raw data, initial visual control only. Use data with great care, errors might be included.

The mycobionts of 103 terrestrial and epiphytic orchid individuals, sampled in the RBSF from permanently estabished orchid plots, were identified by sequencing the whole ITS1-5.8S-ITS2 region and part of 28S rDNA. Tulasnellales, Sebacinales and for the first time Atractiellales were found.

Plots were established by members of UTPL, Dr. Juan Pablo Suarez and his coworkers, on the orchid regeneration land slide, on basis of T1 and in uppar part of T2 as given by geographic parameters. All laboratory work was carried out by the UTPL group mentioned above.

Quality assessment ECSF climate station hourly data: Version 2; Dataset supersedes ver. 1 which is left for reference. Please be aware, that aggregated values may be wrong, due to the data gaps. This is especcially critical for precipitation. Variables: Ta2m =Air Temperature at 2 m (T) PCP = Precipitation at 1 m (P) Huma_2m = relative humidity at 2m (rH) Irradiation = global radiation at 2 m (gRad), widspeed. Emitted radiation, wind direction and soil-temperatures are not yet published For each variable, a measure of uncertainty is given in the original dimension. This value can be considered as the potential deviation from real conditions. Where no parallel measurements exist, the uncertainty is given as the standard deviation of that difference.

Details of data processing are given in the attached Qualityassessment-Document

Rainfall data from the ECSF area in hourly resolution at the FN2 site located at the intersection of Camino Canal and Camino Zig-Zag. Rainfall was measured with an automatic rain gauge (Campbell ARG100, Palo Alto, USA) coupled with a HOBO H07-002-04 datalogger (Onset, Bourne, USA). Event-based recordings were aggregated to hourly data. Rain events occuring during one hour interval were aggregated to the next full hour. Data values are complete unless otherwise indicated by the data gaps below:

Data gaps during the observation period:
03/05/2012 19:02:20.5 to 17/05/2012 15:28:52.0	
20/12/2013 10:36:58.5 to 08/01/2014 15:51:25.0
28/07/2014 15:57:55.0 to 01/09/2014 17:14:27.0
06/10/2014 14:48:25.0 to 15/10/2014 18:09:26.0

Data gaps during the observation period are indicated by values = NULL. Please take these data gaps into account when aggregating precipitation values.

Weekly time series of precipitation data from the San Francisco area at 2000 m a.s.l. at the measuring station FN3 located at the climate station on T2. Precipitation was measured with 5 Hellmann-type pluviometers. The resulting weekly replicates of precipitation were volume-weighted and bulked to one sample per collecting interval. Electrical conductivity and pH values were measured immediately in unfiltered aliquots in the laboratory at the ECSF.

Aggregated values from 2000 are incomplete (May to December).

This dataset has been migrated from the previous FOR402-Database to the FOR816-Database by the Central Data Management Z1/FOR816.
Please keep in mind that the migration included all avilable metainfomation which were accessible through the FOR402-Database. Nevertheless, it can't be guaranteed that no thematic misinterpretation occured in the data/attribute description.
There has been no further disciplin specfic control. In any case of ambiguity please contact the dataset creator.
