Wie beeinflusst das Mikroklima die Dynamik der Biodiversität im Wald?
Lay summary

Die zeitliche und räumliche Dynamik der Biodiversität im Wald wird von den mikroklimatischen Verhältnissen mitbeeinflusst. Diese wiederum sind stark von der Struktur des Waldes geprägt, was zu einem kleinräumigen Muster unterschiedlicher Temperatur- und Lichtverhältnissen im Wald führt. Unser Verständnis des Zusammenhangs zwischen Waldstruktur und Mikroklima ist jedoch lückenhaft und wir wissen wenig darüber, inwieweit das Mikroklima die Auswirkungen des Klimawandels auf die Biodiversität mitbestimmt.

Im vorliegenden Forschungsprojekt erheben wir detaillierte mikroklimatische Messungen in temperierten Wäldern in Europa, um ein prädiktives Modell für das Mikroklima basierend auf der Waldstruktur zu entwickeln. Die Angaben zur Waldstruktur stammen aus Erhebungen im Feld und werden ausserdem aus detaillierten, drei-dimensionalen Fernerkundungsdaten abgeleitet. Dieses Modell wird uns ermöglichen, festzustellen, wie sich das Mikroklima in den vergangenen Jahrzehnten verändert hat und welche Auswirkungen diese Veränderungen auf die Pflanzenzusammensetzung und –diversität haben werden. Die erwarteten Ergebnisse sollen aufschlussreiche Einblicke in die Rolle des Mikroklimas für die Dynamik der Biodiversität im Wald liefern; unser Projekt fördert das Verständnis dafür, wie sich die Waldbewirtschaftung in Zeiten des globalen Klimawandels auf die Biodiversität auswirkt.

Abstract

Understanding the effects of microclimate on forest biodiversity dynamics is of paramount importance to improve the predictions of biodiversity responses to global change. The structure of the forest vegetation creates local-scale heterogeneity in microclimate and light availability, which drives the community composition and diversity of plants and animals. However, it remains unclear how microclimate affects forest biodiversity dynamics and we currently lack a good mechanistic understanding about how forest structure, below-canopy temperatures and light availability independently and/or interactively affect forest plant dynamics. Here, we address this by using highly detailed below-canopy temperature and light availability data to develop predictive models of microclimate and light availability as a function of in situ and remote sensing measurements of forest structure. These models will be applied to study the effects of changes in microclimate and light availability on temporal and spatial dynamics of herb-layer biodiversity. The analyses will be based on a database of forest biodiversity and forest structure containing data on plot-level changes in forest plant species (herbs, shrubs and trees) over time for almost 3000 plots from 55 independent resurvey studies spread across temperate forests in Europe and North America. The expected results will allow for drawing general conclusions about the importance of microclimate for temperate forest biodiversity dynamics. This project will provide insights into potential future pathways of forest biodiversity as a response to global change drivers, such as climate change or forest management regimes. Moreover, the combination of in situ forest measurements with latest developments in remote sensing will pave the way for incorporating fine-grained microclimatic and light availability data into future biodiversity predictions.
