Members of the German Research Consortium met two of their many obligations: They published another high-ranking, multi-author paper and summarized their research results in a booklet for knowledge transfer. The Coordinators also describe how the research stations will operate from now on and how research will continue in a new Research Unit after the official end of the present Research Consortium.
The Science News cover a plant-frugivore network analysis and progresses towards reliable and easy to measure indicators for biodiversity, climate change and land-use alternations in the tropical mountain rainforest, as well as pine-fungi relationships and carbon stocks in Pine plantations in the Paramo ecosystem.

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.
After the coordinators’ updating of the state of research and introducing the new name of this publication, they summarize the important elements of the program for knowledge transfer to stakeholders. The local advisory board informs about a landslide which hit research grounds. Science papers in this issue
• compare tropical montane elevation transects in Ecuador and Peru
• analyze the relationship of decomposer communities and leaf litter types
• demonstrate how fertilization influences the amount of bio-available phosphorus
• reveal that nutrient availability stimulates mineralization of dissolved organic matter
• show that image textures can supersede functional biodiversity analysis
• provide insights into the transformation from abandoned sites to valuable pasture land.
A report presents the completed construction of the last radar of the RadarNet Sur that is situated on a mountain peak and is the highest operating weather radar worldwide. The Data Warehouse manager describes the results of a survey taken to increase data quality and usability. And two workshops transferred gained knowledge on how to perform terrain analyses with the geographical in¬formation system SAGA.

Scientists working in the tropical mountain rain forest of the San Francisco Valley report first results: They depict the impacts of nutrient additions on mycorrhiza as well as on the activity of phosphomonoesterases in the organic layer. Others describe the relationship between canopy evapotranspiration and leaf transpiration derived from a novel observational approach. First research results can also be presented from the other two ecosystems under investigation: leaf phenology and tree water use was analyzed in the dry forest at Laipuna whereas the effects of roads on the avifauna were studied in the Cajas Páramo. One group explains which trees and plots are now equipped with logging band dendrometers and another provides first results on the suitability of functional biodiversity indicators. The afforestation project “Nuevos Bosques para Ecuador” also gives a report and the Data Warehouse now has expanded to Ecuador. The Newsletter rounds off describing the successful approval of the dry forest area in the provinces Loja and El Oro as an UNESCO biosphere reserve where the application initiative was mainly pushed by the non-university partner NCI, supported by the DFG-PAK scientists. It should be stressed that all three DFG-PAK research sites now belong to three different UNESCO biosphere reserves.

The first MRp|SE Newsletter offers research and knowledge transfer results: The test of models for small scale plant distributions shows the advantages of ensemble approaches. This result as well as a new method to analyze canopy evapotranspriation and leaf photosynthesis were awarded with poster prizes. A medical technique helps to study wood anatomy. In contrast to previous data the analysis of fertilized phosphorus revealed that it is not only retained in above-ground biomass and the organic layer but also enters the mineral soil. Mean transit times of water in the catchment and transit time distribution functions where modeled and can be related to land use effects. The Newsletter also explains the usefulness of digital soil maps and the prerequisites for developing local climate indicators. The designs of research plots and new research infrastructures are introduced and the characteristics of the second radar in the Radar Net Sur are summarized. Four of the SENESCYT Bundle Projects describe their research objectives. New in the Data Warehouse are a tool for control of funds consumption and a new booking tool. NCI already awaits researchers at the new Laipuna station.

20 groups of scientists representing a multitude of scientific disciplines summarize major results of their research in this last issue of the TMF Newsletter: They report about science-directed and sustainable land-use systems and present protocols for optimization of sustainable forest and pasture management. Specific reactions of species and of the ecosystem tropical mountain forest (TMF) to increasing loads of nutrient input are shown. The researchers also summarize effects of altered precipitation and temperatures on nitrogen fluxes as well as on plant and animal diversity. They furthermore improved their hydrological models of water fluxes. Landscape parameters and forest dynamics were analyzed to improve landslide models. New animal species and mycorrhiza types are presented, mycorrhiza biomass were determined, and it was analyzed which mycorrhizae foster young trees. How environmental change influences climate and the ecosystem is demonstrated. The milestones achieved in the data warehouse are visualized. The researchers also offer new methods and introduce species to successfully monitor global change impacts.
The speakers give a glimpse on the complex on-site review procedure of the projects which constitute the German part of the new Platform for Biodiversity and Ecosystem Monitoring and Research in South Ecuador. They also report about the Status Symposium which enjoyed a numerous audience.

This issue also informs about recent progress of the foundation NCI, the status of the two transfer projects and the biodiversity results of the cooperating partner project.
The vast biodiversity of the tropical mountain forests once attracted German scientists to start the interdisciplinary research in the remote area of the Ecuadorian Rio San Francisco Valley. Now, after a total of 15 years of German-Ecuadorian research, they have unveiled features hitherto unknown regarding ecosystem constitution, functioning, and services. As they observed this unique ecosystem is locally threatened by non-sustainable land uses like pasture farming. Therefore they developed a science-directed sustainable land use portfolio based on their results and the resilience of the ecosystem against environmental changes. Their recommendations after five years of research in the scope of FOR816 include intensification, diversification, restoration and conservation, and to monitor the impacts of ongoing environmental change.
