Platform data

Overview

Detailed view

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.

Operational taxonomic units (OTUs) of arbuscular mycorrhizal fungi (AMF) detected in roots sampled at the 2000m NUMEX sites in October 2010.

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).

The table is a  list of arbuscular mycorrhizal fungi with their host plants. The sequences are deposited in the NCBI GenBank.

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 throughfall data from the ECSF area in the microcatchment Q2 (transects Q2.1, Q2.2 and Q2.3). Throughfall was measured weekly with 20 Hellmann-type pluviometers at each transect. The weekly replicates were volume-weighted and bulked to one sample per collecting interval and transect. Electrical conductivity and pH values were measured immediately in unfiltered aliquots in the laboratory at the ECSF.

This dataset contains fruit functional traits of fleshy-fruited species at three different altitudes (1000, 2000, 3000 masl)

Data in progress until the end of 2020.
Final data will be available in 2021.

Corrected plots from Bombuscaro, ECSF, Cajanuma, Zamora and Laipuna region as shape files.

Weekly time series of precipitation data from the San Francisco area at 2000 m a.s.l. at the measuring station FN2 located at the intersection of Camino Canal and Camino Zig-Zag. 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 1998 are incomplete (March to December).

Abundance of vascular epiphytes (incl. hemiepiphytes) in 10 x 10 m plots across a land-use gradient.
All samples (columns) give abundance data for vascular epiphyte assemblages in plots of 10x10 meters. PT = Handtuchfläche secondary forest (RSF), Ai = secondary forest at Arco Iris (Ai1: around Ai-building, Ai2-plots on neighbouring ridge towards W), Q2 = Quebrada 2 (RSF), Q5 = Quebrada 5 (RSF), PP = Pinus plantation above ECSF, LC = Loma Chamusqiuín (1-4: secondary forest below Loja-Zamora road, 5-8: secondary forest above Loja-Zamora road). SF = tall secondary forest at RSF, DF = tall degraded forest at RSF; MF = mature (undisturbed) forest at RSF.
Geogr. coordenates still need to be added.

Soil texture were sampled in the young landslide in front of the station, on the other side of the San Francisco river. Soil samples were analysed in the laboratory of the University of Bayreuth.

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.

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.
