The development of ecosystem research in groundwater ecology was complemented especially
from 1990s onwards, by a new perception that the biological diversity in dynamic
ecosystems is more important than earlier conceived (DANIELOPOL et al., 2000a; GRIEBLER
and LUEDERS, 2008). This novel view on the biodiversity of subterranean aquatic organisms
in relation to ecosystem functioning represents the next important paradigm switch that we
will highlight.
