A relatively new concept, 'global change', refined over the last decade to account for the energy - land use - climate change nexus, describes all changes induced by the human species and its activities affecting natural ecosystems and their biodiversity. This chapter reviews several research projects carried out within the national boundaries of Romania, all attempting to pinpoint, explain and predict the impact of 'hotspots' showing potential threats

‘Global change’ is a relatively recent concept, related to the energy - land use - climate change nexus, and designated to include all changes produced by the human species and the consequences of its activities over natural ecological complexes and biodiversity. The joint effects of these drivers of change are particularly relevant to understanding the changes of biodiversity. This study overlaps results of previous studies developed in Romania
