Um die Mitglieder dieser multi-nationalen DFG-Forschungsgruppe (Research Unit, FOR) zu vernetzen und sich gegenseitig knapp aber zitierfähig (DOI) über jüngste Forschungsfortschritte zu informieren, veröffentlicht das Forschungsteam regelmäßig ein Bulletin. Darüber hinaus bleiben DFG und andere Forschungsförderer auf dem neuesten Stand über Entwicklungen auf der Forschungsstation sowie der Aktivitäten der nationalen Partner-Organisationen und Partner-Universitäten. Der Newsletter wird in englischer Sprache veröffentlicht. Die interdisziplinäre Forschungsgruppe mit Biowissenschaftlern, Klimaforscherinnen, Bodenkundlern und Ökosystem-Modelliererinnen, u.a. untersucht Antworten und Rückkopplungseffekte der Biodiversität auf Umwelt- und Klimaveränderungen in den extrem artenreichen Ökosystemen im Süden Ecuadors.

Tabebuia Bulletin of the DFG Research Unit 2730

English newsletter, 44 pages

8^th issue (November 2020)

The new issue of the Tabebuia Bulletin of the RESPECT Research Unit presents the new biodiversity land surface model Hydroatmo Unified Model of BiOtic interactions and Local Trait Diversity (HUMBOL-TD) and how it integrates hydrologic, biodiversity-related and atmospheric parameters. The bulletin summarises the research results of the individual projects that could be achieved despite the COVID-19 pandemic which overshadowed the entire work. Researchers report about responses and feedback effects of climate and land-use changes on abiotic drivers, biodiversity and ecological processes in this hotspot area. In details this Bulletin covers:

• Hyperspectral data products that can be used to parameterize and test the LSMAtmo model
• Partitioning net ecosystem exchange into gross primary productivity and ecosystem respiration
• Simulating response and effect mechanisms of global change on hydrological processes
• Response of nutrient supply to climate and land-use changes
• Implementing biotic interactions into a process-based dynamic vegetation model
• Functional traits: Effects of phylogeny and elevation and the relation to tree growth
• Plant functional types that can be differentiated by their response to transitory drought events  
• Radial variability of wood functional traits in the pioneer tree Heliocarpus americanus
• Evapotranspiration as an essential variable bridging climatology, soil science and plant ecophysiology
• Reproductive traits of fleshy-fruited plants
• How plant traits and arthropod communities influence herbivory

Beyond, the bulletin reports on establishment and repair of field infrastructure, recent advances of the data warehouse and the reconstruction of climate time series. Finally, research projects from Ecuadorian counterparts and milestones reached by the infrastructure providers round off the issue.

6^th issue (February 2019)

The first Tabebuia Bulletin of our new Research Unit RESPECT summarizes the installation of our new plot system including the measuring devices and first verification of the newly established methods. First research achievements include the following aspects: plant functional types (PFT), water and carbon fluxes, tree above- and belowground traits, soil development, photosynthetic gas exchange measurements, abiotic covariates, functional trait diversity and herbivory, and optimization of biomass gain on pastures. Our Ecuadorian partner NCI reports advances in the establishment of newly protected areas and the Ecuador’s INABIO institution introduces itself. Videos of our previous research are available via our website and data warehouse, which now also offers new search features for publications as well as upload information.

5^th issue (October 2016)

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.

4^th issue (December 2015)

Science and Knowledge-Transfer news encompass

- first full-length paper on the competition between pasture grass (Setaria) and strong weed (bracken)
- how tree roots and the mycorrhiza fungi respond to nutrient manipulations
- in which way phosphate liberating soil enzymes depend on climatic conditions
- why the altitudinal gradient of tree assemblages disproved the general validity of the Tropical Conservatism Hypothesis.
- which measures are appropriate to determine daily carbon uptake in trees
- which tree functional types display different water relations in the dry forest
- how to create a soil map for remote or less accessible areas
- which sampling design for digital soil mapping closes the gap between the statistical desired quality of samples and operational applicability
- in which way the high resolution climate indicator system can be used to recognize climate change in southern Ecuador

Also: how workshops enthuse pupils with bird diversity and seed dispersal, teach science-directed advances in ecosystem monitoring and rehabilitation of abandoned areas

2nd issue (November 2014)

Scientists working in the tropical mountain rain forest 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 derive from the other two ecosystems under investigation: leaf phenology and tree water use was analyzed in the dry forest whereas the effects of roads on the avifauna were studied in the Cajas National Park. 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. Now all three research sites belong to three different UNESCO biosphere reserves.
