Grassland diversity related to the Late Iron Age human population density (2007)
Partel, M, Helm, A, Reitalu, T, Liira, J, Zobel, M
1 Species-rich semi-natural grasslands in Europe developed during prehistoric times and have endured due to human activity. At the same time, intensive grassland management or changes in land use may...
Dormann, C., Schweiger, O., Augenstein, I., Bailey, D., Billeter, R., ...
Aim Species richness in itself is not always sufficient to evaluate land management strategies for nature conservation. The exchange of species between local communities may be affected by landscape...
Yu, H.M., Ziegler, C., Oszcipok, M., Zobel, M., Hebling, C.
The catalyst layer is one of the key components of PEMFCs. As the electrochemical reaction occurs at the three-phase interface of the catalyst layer, it is necessary to investigate the hydrophobicity...
