Millennial–length tree–ring records: A basis for climate reconstruction an assessment of climate extremes and trends at local to global scales

(Multi-) proxy temperature reconstructions over the Common Era are crucial not only to place current temperature trends in a long-term context, but also to assess the full range of natural and anthropogenic climate forcings. However, estimates of the first millennium remain poorly constrained due to a paucity of millennial long tree-ring records causing a spatial under-representation of some regions in larger scale climate reconstructions and increasing uncertainty in the interpretation of climatic trends and extremes.

Population dynamics in a changing world: The consequences of environmental variation for species with complex life histories

Population dynamics in a changing world: the consequences of environmental variation for species with complex life histories Despite increasing awareness of the importance of environmental variation in ecological systems, there are still many open questions about how variation affects population dynamics. I studied several aspects of environmental variation and the roles it plays in population dynamics, particularly for species with complex life histories: (1) How do the the effects of native insect herbivores on the population dynamics of an invasive thistle vary across space?

FTIR spectroscopy as a potential tool in dendroarchaeology

Infrared spectroscopy is a well proven tool in the assessment of molecular structures. The presentation elaborates applications of this method to archaeometric questions. The main focus will be set on the prediction of sample age. Currently, dating tools are worked out best for wood. But also the possibilities for other materials are presented.
