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.

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.

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.

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.

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.

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

Measurements of gas flux (CO2, CH4, N2O) in canopy soils of NUMEX plots on four dates (Sept/Nov 2011 and Jan/April 2012). Measurements were taken in 3 of the 4 NUMEX blocks at each elevation; treatments measured included C, N, NP and P.

Gas fluxes were measured by incubating intact soil cores.
Gas samples were analyzed on a gas chromatograph with a FID and ECD.
Note that the units for CO2 are mg CO2-C m-2 h-1 (not g CO2-C).

Weekly time series of precipitation data from the ECSF area 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.

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.
