Dynamic Macroecology
The dynamic
macroecology group studies different aspects of ecology on large spatial and
temporal scales related to the question “How do species and their traits change
in space and time, particularly with global change?”
Research foci:
- spatial
dynamics of species and their diversity
- effect
of climate change on species and diversity
- niche
evolution
Topics:
- forest species dynamics and
migration, effects of current and past climate change (H.Lischke, J. Nabel)
- coupled forest species and
biogeochemical dynamics, effects of climate change (H.Lischke, M. Scherstjanoi)
- feedbacks of spatial forest dynamics
to the abiotic and anthropogenic environment (H. Lischke, N. Zurbriggen)
- broad-scale patterns of species diversity like altitudinal or latitudinal gradients (M. Nobis, P. Pearman)
- distributions of functional groups
of species and effects of climate change, including biological invasion
(M.Nobis, P. Pearman)
- niche/trait evolution, comparative
phylogenetics and phylogeograhy (P. Pearman, M. Nobis)
- phylogenetic community structure (P.
Pearman, R. Wüest)
Main methods:
- climate
(change) data scaling and provision (D. Schmatz, N. Zimmermann)
- dynamic
ecological models and model scaling (H. Lischke)
- statistical
ecological models, e.g. species distribution models, phylogenetic comparative
methods (N. Zimmermann, P. Pearman, M. Nobis)

KLIWAWA - Verbesserung der Klimaabhängigkeit der Wachstumsfunktion für Szenarienanalysen der Waldentwicklung (Holznutzungspotential, Nachhaltigkeit)
|
Die Schweizer Waldwirtschaft wird wegen dem Klimawandel mit veränderten Wachstumsverhältnissen im Wald konfrontiert. In diesem Projekt sollen verbesserte Beschreibungen der Umweltabhängigkeiten für die Modellierung des Baum- und Bestandeswachstums hergeleitet werden. Der Einfluss von Temperatur, Niederschlag und Stickstoff auf das Wachstum wird mittels vorhandener Datengrundlagen analysiert, voneinander und von weiteren Einflüssen separiert, und Abhängigkeitsfunktionen für Waldwachstumsmodelle werden erarbeitet.

Borkenkäfer als Schlüsselfaktoren der zukünftigen Waldnutzung?
|
Falls durch den Klimawandel die Wichtigkeit der Stürme zu- und die Widerstandskraft der Wirtsbäume abnehmen, können Borkenkäfer limitierend wirken. Entlang von Höhengradienten in Fichtenwäldern werden die Populationen von Borkenkäfern und natürlichen Feinden sowie die Vitalität der Fichten erhoben.

Evolutionary Niche dyNamics of Invasive Species (ENNIS)
|
ENNIS is a project that seeks to understand how the evolutionary history of the ecological niche can influence whether species become invasive in regions to which they are introduced.

Spatially Explicit Evolution of Diversity (SPEED)
|
This is an interdisciplenary project, financed by the SNF Sinergia program, to investigate niche evolution. We seek to understand how niche evolution will contribute to patterns of biodiversity under altered climates.

MAIOLICA: Simulation of vegetation emitted greenhouse gases
|
Greenhouse gases emitted from vegetation feed back on the atmospheric chemistry and climate. We aim to simulate such vegetation produced greenhouse gases and to provide information on emissions from other sources.

Räumliche Muster der Biodiversität auf Landschaftsebene
|
Modelle der WSL zeigen, welche Landschaften in der Schweiz besonders artenreich sind und welche Einflussgrössen die Artenvielfalt unterschiedlicher Organismengruppen bestimmen. Die Arbeiten liefern Grundlagen für ein besseres Verständnis und den Schutz von Artenvielfalt auf Landschaftsebene.

Developing a physiologically mechanistic tree migration model and simulating Holocene spread of forest trees
|
The potential of plants to migrate to habitats which are more favourable under changed conditions plays a key role in assessing the impacts of climate change on terrestrial ecosystems. A new, spatially explicit, physiologically mechanistic, and efficient forest succession model was developed in order to study the potential of trees to invade, migrate and get extinct under current and possibly changed future climate.
