Prof. Gerald Jurasinski

Since January 2023, Dr.Gerald Jurasinski has held the peat professorship at the University of Greifswald.

Topics of his research are: Methods of biodiversity assessment on ecosystem to landscape scale as well as the extrapolation of gas flow measurements in the area via vegetation proxies. Geostatistical and quantitative vegetation-scientific methods are used to record the spatio-temporal variability of vegetation stands and to relate them to environmental parameters.

    Research

    DFG Research Training Group "Baltic TRANSCOAST" – understanding the coastal ecocline

    Beginn: 1/2016

    Baltic TRANSCOAST investigates the water and solute exchange between land and sea across the coastal ecocline in an interdisciplinary team bringing together marine and terrestrial scientists. We regard the coastal ecocline as a continuum and focus our research on three, strongly interrelated research fields, namely hydrodynamic, (bio)geochemical and biological processes. Cooperations across the research fields underline the interdisciplinary character of the research training group. Closely linked investigations will be conducted by all PhD students at one common study site, the nature reserve "Heiligensee and Hütelmoor", north-east of the city of Rostock. The research is supported by existing high-end infrastructure provided by both hosting institutions University of Rostock and the Leibniz Institute for Baltic Sea Research Rostock-Warnemünde (IOW).

    DFG project  "Hüttelmoor"

    Start: 10/2010-2013: Modeling of area-related material flows based on greenhouse gas flow measurements (closed chamber) over spatial patterns of the vegetation.

    Gas flows and thus material budgets in ecosystems play an important role in assessing the climate relevance of land use types with regard to the predicted climate change.  Greenhouse gas measurements, using chambers and eddy covariance measurements are the two methods used to detect them. Both methods have been tested but have not been conclusively discussed.

    Chamber measurements are associated with a high spatial and temporal variability. On the one hand, this is due to the seasonal developments in ecosystems and, on the other hand, to the spatial variability of the plant cover and the microorganism communities associated with it. In the intended project, the composition of the vegetation in a heavily degraded, saltwater-influenced, rewetted fen on the Baltic Sea coast is to be used in order to transfer gas hood measurements arranged in a regular grid to the area.

    For this purpose, the vegetation is recorded using a regular equidistant grid of recording areas, the connection between rivers and vegetation is analyzed (geographically weighted regression, other multivariate and geostatistical methods) and the areal distribution of the gas flows is modeled with the help of remote sensing data obtained on site. This can be of great importance for areal statements on COâ‚‚ and CHâ‚„ fluxes...

     

    simba R

    Package with functions for similarity analysis including preparation/post-processing and permutation tests

    simba  is an R Paket for calculating different similarity measures and their further analysis. It includes functions to calculate mantle correlations between matrices and to automatically calculate data points for mantle correlograms.

    Also included are functions for creating artificial datasets and preparing species data for analysis. The package is still under development and is published on CRAN.

    Different developer versions of the package can be downloaded from this page. They are built under Mac OS 10.4.10 and R 2.5.1 or under Windows XP and R 2.4.1. The whole thing is in the beta stage. The corresponding binary version of CRAN is probably the most suitable for most users. If one of the versions offered below on this page is to be installed, the binaries are installed from the R console with the following command:

    install.packages(file.choose(), repos=NULL, type='binary')
