The issue presents a bunch of Science and Knowledge-Transfer News. The first full-length paper in this journal shows in a model how the equilibrium between the pasture grass (Setaria) and the competing weed (bracken) depends on the temperature of the site, in other words on the elevation of the pasture.
 
  
In the mountain rainforest, tree roots and the mycorrhiza fungi respond species-specifically to nutrient manipulations. Phosphate liberating soil enzymes depend on climatic conditions and thus on the altitudinal gradient. A study of the altitudinal gradient of tree assemblages disproved the general validity of the Tropical Conservatism Hypothesis. Using water use efficiency of the leaves and the total water consumption of the tree allows determination of its daily carbon uptake. Sodium availability could play an essential role in litter decomposition. In the dry forest different tree functional types can be recognized by quantification of their water relations.
 
 
How to create a soil map for remote or less accessible areas? The Transfer News present a sampling design for digital soil mapping that closes the gap between the statistical desired quality of samples and operational applicability. The high resolution climate indicator system can be used to recognize climate change in southern Ecuador. In a workshop on the National Bird Day researchers from the Platform shared their dedication to bird diversity and seed dispersal with students from Zamora Chinchipe. Two more workshops transferred knowledge about science-directed advances in ecosystem monitoring and about the rehabilitation of abandoned areas for production and protection. More than 50% of the visits of the Data Warehouse are from outside the Research Consortium and climate data are expectedly the champions of downloads. News from the ECSF research station, the infrastructure provider NCI as well as the successful completion of three PhD thesis by Ecuadorian students round off this issue.
