Lead
Das Ziel des Projektes ist es die Boden-Biodiversität in Wäldern entlang eines Klimagradienten zu erfassen. Entlang dieser Transekte werden die fünf wichtigsten Klimatypen (boreal, kontinental, atlantisch, alpin, mediterran) Europas abgedeckt. Wichtige funktionelle Gruppen des Nahrungsnetzes im Boden wie Bakterien, Pilze, Nematoden, Springschwänze, Milben und Regenwürmer werden sowohl morphologisch wie auch mittels DNA Metabarcoding bestimmt.

Charakterisierung von Nahrungsnetzen wichtiger Bodenorganismen in Böden von europäischen Wäldern entlang eines Klimagradienten

Linking forest soil food-webs patterns with soil organic matter characteristics across five European biogeographical regions

Das Ziel des Projektes ist es die Boden-Biodiversität in Wäldern entlang eines Klimagradienten zu erfassen. Entlang dieser Transekte werden die fünf wichtigsten Klimatypen (boreal, kontinental, atlantisch, alpin, mediterran) Europas abgedeckt. Wichtige funktionelle Gruppen des Nahrungsnetzes im Boden wie Bakterien, Pilze, Nematoden, Springschwänze, Milben und Regenwürmer werden sowohl morphologisch wie auch mittels DNA Metabarcoding bestimmt.

Inhalt und Ziel des Forschungsprojektes

In diesem Projekt sollen die wichtigen Bodenorganismen innerhalb der Nahrungsnetze in Böden europäischer Wälder entlang eines Klimagradienten charakterisiert werden. Die Bodenproben werden nach einem vorgegebenem Protokoll von den Projektpartnern entnommen und an die WSL geschickt. Hier werden die Bodenproben verarbeitet, die Bodenfauna ausgetrieben und die Bodenorganismen bestimmt. Dazu wird das Erbgut aus dem Boden extrahiert. Die Artenvielfalt wird sowohl taxonomisch wie auch mittels DNA Metabarcoding bestimmt.

Wissenschaftlicher und gesellschaftlicher Kontext des Forschungsprojektes

Mit den DNS-Analysen und der morphologischen Charakterisierung der Bodenfauna kann die Bandbreite der standorttypischen Lebensgemeinschaften genauer beschrieben werden. Diese Daten können zukünftig als Referenzwerte dazu verwendet werden, gemessene Werte hinsichtlich einer Bedrohung der Boden-Biodiversität besser beurteilen zu können. Im weiteren helfen diese Daten Nahrungsnetze im Boden besser zu verstehen und führen zu verbesserten Modellen zum Abbau von organischen Materials in Böden.

Abstract

Decomposition of soil organic matter (SOM) is the most important biological process in soil. SOM is biologically transformed by microorganisms and soil fauna and stabilized in organo-mineral complexes with different turnover rates. Biogeochemical SOM models aim at predicting the dynamics of SOM and, thereby, the changes in global C cycling. However, SOM modelling has so far largely ignored the contribution of the soil fauna. The proposed project aims to characterize the main functional trophic groups of the soil food web across European forests and link them with biogeographical regions, climatic factors, and soil properties. We will determine functional groups, sampled in-situ from 30 forest research plots across 5 European biogeographical regions using morphology-based classification and DNA metabarcoding. hThe detailed analysis of the soil food web coupled with SOM characteristics will significantly improve our understanding of the soil biota in the context of ecosystem services such as global C cycling and will allow the development of better predictive C models.
