Lay Summary (German)

Lead
Die Suche nach den zugrunde liegenden Mechanismen der Beziehungen zwischen Produktivität und Biodiversität konzentrierte sich bisher meist auf die Ressourcen-Komplementarität für Nährstoffe, Licht und Wasser. Architektonische und phänologische Diversität, die zu räumlicher und zeitlicher Nischenkomplementarität führen kann, wurde dagegen im Jena (Haupt-) Experiment kaum untersucht.
Lay summary
Wir planen zeitlich und räumlich hochaufgelöste Datensätze optischer Merkmale zu erheben (WP1), die es uns erlauben, die folgenden Fragen zu beantworten: Wie führt Diversität in Gestalt und Architektur zu einer effizienten Raumnutzung? (WP2); wie ändern sich phänologische Nischen in Abhängigkeit von Diversität, und führen so über einen längeren Zeitraum zu erhöhter Ressourcennutzung auf Bestandesebene? Können Phänologiemodelle, die Bestandesentwicklung und Produktivität nur aufgrund von Klimavariablen vorhersagen, durch die Berücksichtigung von Pflanzen-diversität verbessert werden? (WP3); wie kann Diversität, d.h. Artenreichtum, architektonische und phänologische Diversität, die Grössenordnung und die zeitliche Entwicklung von Transpiration und Wassernutzungseffizienz auf Art- und Bestandesebene beeinflussen? (WP4). Dafür wird eine einzigartige Kombination von hochmodernen Techniken nutzen, einschliesslich digitaler Bilderfassung (automatisiert auf Bestandesebene, Nahaufnahmen, Wärmebildaufnahmen) mit unterschiedlichen zeitlichen Auflösungen (mehrmals am Tag bis vierzehntägig), räumlich hochaufgelösten biometrischen Inventaren, Aufnahmen phänologischer Merkmale auf Art- und Bestandesebene sowie spektrale, chemische und Isotopenanalysen. Wir werden auch bereits existierende Datensätze des Hauptexperimentes nutzen (Traitmerkmale, Phänologie, Oberflächentemperaturen). Mit Hilfe dieser hochaufgelösten Messungen im Trait-Experiment und Validierungsmessungen im Hauptexperiment, werden wir Daten zur Bestandesstruktur und zu Ökosystemfunktionen erheben, die es uns erlauben, unsere übergeordnete Hypothese zu testen, dass räumliche und zeitliche Nischenkomplementarität zu den beobachteten Biodiversitätseffekten auf Ökosystemfunktionen beitragen.

Abstract

The quest to find the underlying mechanisms of observed productivity-biodiversity relationships has often focussed on nutrient, light and water use complementarity. In contrast, architectural and phenological diversities giving rise to spatial and temporal niche complementarities have hardly been addressed in the Jena (main) Experiment. However, with the new trait-based experiment, we can now address such aspects at species and community levels. In particular, we will acquire high temporal and spatial resolution datasets on optical properties (WP1) that will allow us to address the following questions: How does diversity in plant stature and architecture translate into efficient exploitation of above-ground space? (WP2); how do phenological niches change in response to diversity, allowing communities to exploit resources over an extended period of time? Can phenology models - predicting community stand development and productivity solely with climate inputs - be improved by including information on plant diversity? (WP3); how does diversity, i.e., species richness, architectural and phenological diversities, affect magnitude and temporal development of plant and ecosystem transpiration and water-use efficiency? (WP4). We will use a unique combination of state-of-the-art techniques, including digital imaging techniques at sub-daily to bi-weekly time steps (time-lapse, close-range, thermal), fine-scale canopy inventories, phenological trait assessments at plant species and community level, spectral, chemical and isotopic foliar analyses as well as already existing data sets from the main plots (on traits, phenology and surface temperatures). Based on these high-resolution measurements within the trait-based experiment and validation measurements on the main plots, we will acquire proxy data of community structure and functioning to address our overarching hypothesis that spatial and temporal niche complementarities contribute to the observed biodiversity effects on ecosystem functioning.
