The structural complexity of the basin fill is given by the configuration of the Zechstein salt with salt diapirs and salt pillows. This special configuration is very relevant for the thermal calculations because salt has a distinctly higher thermal conductivity than other sediments. We calculate the temperature using a FEMethod to solve the steady state heat conduction equation in 3D. Based on this approach, we evaluate the sensitivity of the steady-state conductive thermal field with respect to different lithospheric configurations and to the assigned thermal properties. We compare three different thermal models: (a) a crustal-scale model including a homogeneous crust, (b) a new lithosphere-scale model including a differentiated crust and (c) a crustal-scale model with a stepwise variation of measured thermal properties. The comparison with measured temperatures from different structural locations of the basin shows a good fit to the temperature predictions for the first two models, whereas the third model is distinctly colder. This indicates that effective thermal conductivities may be different from values determined by measurements on rock samples. The results suggest that conduction is the main heat transport mechanism in the Brandenburg area.

In this study, we aimed at projecting the availability of suitable habitat for an endangered amphibian species, the Fire-bellied toad Bombina bombina, in Brandenburg (north-eastern Germany). We modelled a potential habitat distribution map based on (1) a database with 10,581 presence records for Bombina from the years 1990 to 2009, (2) current estimates for ecogeographical variables (EGVs) and (3) the future projection of these EGVs according to the statistical regional model, respectively, the soil and water integrated model, applying the maximum entropy approach (Maxent). By comparing current and potential future distributions, we evaluated the projected change in distribution of suitable habitats and identified the environmental variables most associated with habitat suitability that turned out to be climatic variables related to the hydrological cycle. Under the applied scenario, our results indicate increasing habitat suitability in many areas and an extended range of suitable habitats. However, even if the environmental conditions in Brandenburg may change as predicted, it is questionable whether the Fire-bellied toad will truly benefit, as dispersal abilities of amphibian species are limited and strongly influenced by anthropogenic disturbances, that is, intensive agriculture, habitat destruction and fragmentation. Furthermore, agronomic pressure is likely to increase on productive areas with fertile soils and high water retention capacities, indeed those areas suitable for B. bombina. All these changes may affect temporary pond hydrology as well as the reproductive success and breeding phenology of toads.

BT - A case study in NE Germany BT - Eine Fallstudie aus Nordostdeutschland N2 - The external dispersal ("epizoochory") of vascular plant diaspores (seeds and fruits) by roe deer and wild boar, i.e. the most common wild large mammals with a large home range in central Europe, was investigated in a 6.5-km² forest area in NE Germany dominated by mesic deciduous forests. The study involved brushing out the diaspores from the coats and hooves of 25 shot roe deer and nine wild boar. The results were compared with the forest vegetation of the study area. Whilst wild boar transported large amounts of various diaspores in the coat, the significance of roe deer for epizoochory was low due to their sleek fur and different behaviour compared to wild boar. Altogether, 55 vascular plant species were transported externally. Since only a limited number of seeds came from woodland habitats, the open landscape was at least as important as a source of attached seeds as the forest vegetation. Thus, most plant species occurring in the studied forest area, especially characteristic woodland herbs, showed no adaptations to epizoochorous dispersal, although being very abundant in the herb layer. We conclude that hoofed game play a particular role concerning the dispersal of ruderal and grassland species in the agricultural landscape of central Europe. However, the actual spread of some herb species in forests of northern Germany, e.g. Agrostis capillaris, Brachypodium sylvaticum, Deschampsia flexuosa, Galium aparine and Urtica dioica, may be mainly facilitated by wild ungulates. Though dispersal by large mammals is an important mechanism for long-distance dispersal of plants in general, our results suggest that most of the characteristic herb species of mesic deciduous forests have only low epizoochorous dispersal potentials. The implications for nature conservation and silviculture are discussed. N2 - Die Ausbreitung von Gefäßpflanzen-Diasporen (Samen und Früchte) durch äußerliche Anhaftung ("Epizoochorie") an Rehen und Wildschweinen, den beiden häufigsten Schalenwild-Arten in Mitteleuropa, wurde im 6,5 km² großen Forst Brieselang bei Berlin (Bundesland Brandenburg) untersucht, in dem mesophile Laubwälder vorherrschen. Dazu wurden die Felle und Hufe von 25 geschossenen Rehen und neun Wildschweinen ausgekämmt und die Diasporen anschließend bestimmt. Die Ergebnisse wurden mit der Waldvegetation verglichen. Während Wildschweine große Mengen verschiedener Diasporentypen transportierten, war die Bedeutung von Rehen für die Ausbreitung von Pflanzen auf Grund des glatten Fells und der im Vergleich zum Wildschwein unterschiedlichen Verhaltensweisen wesentlich geringer. Insgesamt wurden 55 Phanerogamenarten epizoochor transportiert. Da nur ein kleiner Teil der ausgebreiteten Pflanzen Waldhabitate bevorzugt, war das Offenland eine mindestens ebenso wichtige Quelle anhaftender Diasporen wie die Waldvegetation. Die meisten Waldpflanzenarten wurden nicht ausgebreitet; insbesondere solche Arten, die ausschließlich in Wäldern wachsen, wurden nicht nachgewiesen. Viele Pflanzenarten sind – vermutlich auf Grund ihrer Diasporenmorphologie – weitgehend vom Transport ausgeschlossen, obwohl sie sehr häufig in der Krautschicht des untersuchten Waldes vorkommen. Daher ist Schalenwild in der Agrarlandschaft Mitteleuropas vermutlich vor allem für die Ausbreitung von Ruderal-, Segetal- und Grünlandpflanzen von Bedeutung. Die Ausbreitung einiger Pflanzenarten der Krautschicht in norddeutschen Wäldern z.B. Agrostis capillaris, Brachypodium sylvaticum, Deschampsia flexuosa, Galium aparine und Urtica dioica, könnte jedoch wesentlich auf Schalenwild zurückgehen. Obwohl Großsäuger insgesamt ein wichtiger Vektor für die Fernausbreitung von Pflanzen sind, zeigt unsere Studie, dass die meisten charakteristischen Waldbodenpflanzen mesophiler Laubwälder kaum ausgebreitet werden, also nur ein geringes epizoochores Ausbreitungspotenzial aufweisen. Die Bedeutung der Ergebnisse für den Waldnaturschutz und den Waldbau wird diskutiert. T2 - Trägt Schalenwild durch Epizoochorie zur Ausbreitung von Gefäßpflanzen in mitteleuropäischen Wäldern bei?
