Anthropogenic landforms are attractive landscape structures. They are linked to the cultural elements of the landscape and they also support biodiversity on the landscape level. Concerning their position within heritage concepts, anthropogenic landforms can be seen as a bridge between natural and cultural heritages. This paper is focused on the relevance of anthropogenic landforms to landscape management and planning. The study is based on the concept of geomorphosites, which can be applied within sustainable management and the conservation of geomorphological heritage. The case study was applied in the urban area of Brno (Czech Republic). The results of the study indicated the importance of anthropogenic landforms for urban landscape conservation and sustainable tourism development. The assessment of landforms in the study area enabled to establish a set of recommendations for the sustainable management of anthropogenic landforms in Brno. This study suggested the assessment of anthropogenic landforms as a support tool for sustainable landscape management in urban areas.
Climatically induced shifts of species’ geographic ranges can provide important information about the potential future assembly of ecological communities. Surprisingly, interspecific variability in the magnitude and direction of these range shifts in birds has been the subject of few scientific studies, and a more detailed examination of species’ ecological traits related to this variability is needed. Using maps in the Climatic Atlas of European Breeding Birds (Huntley et al. 2007) we calculated the potential shifts of European breeding ranges in 298 bird species, and explored their relationships with breeding habitat, dietary niche, migration strategy, life history and geographic position of the current breeding range. Breeding habitat type showed the strongest relationship with the potential range shifts, with forest and wetland species showing the largest magnitude of shift. At the same time, ecological specialists showed a larger magnitude of shifts than generalists. In addition, we found that species with current ranges situated near continental borders and species with lower migratory capacity are more limited in their potential to shift due to climate change. Our analyses thus indicate which ecological groups of birds will be most likely forced to move their ranges under predicted climate change. This knowledge can help to adopt proper conservation actions. These actions will be particularly important in the case of specialist species, which have been shown to be the most sensitive to climate change impacts
Precipitation leaches soil organic matter (SOM), transporting it downward where it accumulates at the soil–bedrock interface. Intensive agriculture, particularly tillage, accelerates this process. Microbial decomposition of SOM generates CO2, forming a gas-rich soil layer (GRSL)—a phenomenon long hypothesized but never directly confirmed until now. Drilling on the Harbechy Plateau (Moravian Karst) revealed a GRSL with a thickness of ~0.8 m, CO2 concentrations averaging 1.5–3 vol. % (peaks of 4–6 vol. %), and isotopic signatures (δ13C) indicating a mix of biogenic (−25‰) and atmospheric (−8‰) CO2. These findings necessitate re-evaluation of carbon cycling models in karst agroecosystems.
