Persönliches Profil

Tätigkeit an der ZHAW als

Arbeits- und Forschungsschwerpunkte, Spezialkenntnisse

Research Interests

• Management and improvement of ecosystems which are important for nature conservation
such as semi-dry meadows, wetlands, forest edges in Switzerland and succulent scrub and
Juniper-woodland in Tenerife.
• Long-term monitoring of vegetation change; invasion of neophytes.
• The natural variation of vegetation systems in space and time, e.g. based on long-term
permanent plots in the Swiss National Park).
• Secondary succession on subalpine grasslands: dynamics of population structure and
genetics of dominant graminoids (Carex sempervirens, Brachypodium pinnatum).
• Tree establishment at Alpine timberlines and on abandoned subalpine pastures: impacts
of climate change and deer pressure.
• Primary succession on glacier forelands.
• Interactions between vegetation and herbivores in the Swiss National Park.
• Remote-sensing-based vegetation mapping succession modeling.

Keywords

• FIELDS OF INTEREST: vegetation ecology, community patterns in space and time,
vegetation dynamics, quantitative vegetation analysis, nature conservation, population
biology
• PROCESSES: primary and secondary succession at species and community levels, vegetation-
herbivore-interactions, plant invasions (trees, clonal graminoids, exotic species),
population dynamics, land-use change, climate change
• ECOSYSTEMS: grasslands (colline, subalpine, alpine), timberline ecotones, glacier
forelands, succulent scrub and Juniperus-woodland on Tenerife
• TOPICS: floristic diversity, population biology, longevity of clonal graminoids,
intermediate disturbance hypothesis, reproductive effort, old field succession,
preservation of semi-dry grasslands, ecological improvement of forest edges,
restoration of Juniperus-woodland
• METHODS: floristic releves, long-term permanent plot research, multi-scale studies,
management experiments, phenology, dendrochronology, isozyme analysis, multivariate
analysis of spatial and temporal patterns, GIS-based modelling
• SPECIES: Bromus erectus, Brachypodium pinnatum, Carex sempervirens, Juniperus turbinata
ssp.canariensis, Larix decidua, Pinus cembra, Pinus montana, Typha glauca
• LOCATIONS: Swiss National Park, Morteratsch-Glacier (Switzerland), Tenerife (Canary
Islands), Montpellier (France), Bay of Fundy (Nova Scotia, Canada)
