Due to the loss of many natural water bodies, artificially created ponds often serve as refuge for numerous endangered species. The history of pondscapes in Central Europe is closely tied to the introduction of the common carp. Changing political, social, and climatic conditions, along with the increasing threat from fish-eating species, make the economic viability of pond aquaculture increasingly fragile. However, maintaining...

The geometry of large-scale extensional deformation in the southwestern Cyclades archipelago is a controversially discussed issue. Recent studies suggest a bivergent (i.e., coeval top-to-the-S and top-to-the-N shear) geometry of early Miocene extensional deformation. On Sikinos Island, top-to-the-S shear structures in the Cycladic basement are overprinted by a prominent ductile-to-brittle top-to-the-N extensional shear zone in...

We report three U–Pb sulfate ages from the recently identified Intra-PQ Thrust within the Phyllite–Quartzite (PQ) Nappe of the Ionian high-pressure belt of the external Hellenides in the eastern Mediterranean. Crosscutting relations show that a distinct pressure-solution laminae/microlithon fabric is the oldest deformation structure. Two analyses of sulfate minerals that are part of this structure yielded indistinguishable dat...
