Towards an optimal sampling strategy to assess groundwater biodiversity: comparison across six European regions
Summary 1. Reliable assessments of groundwater biodiversity are urgently needed to resolve current issues relating to the protection of aquifers. The assessment of groundwater biodiversity isExpand
Groundwater biodiversity patterns in the Lessinian Massif of northern Italy
SUMMARY 1. The distribution patterns of stygobiotic invertebrates were examined with a stratified sampling design at 197 sites selected among four hydrogeographic basins in the Lessinian MassifExpand
The biology and ecology of lotic microcrustaceans
Ecological requirements such as hydraulic microhabitats and geomorphologic features of the streambed are the major determinants of species diversity and abundance for benthic microcrustacea of lotic habitats. Expand
Diversity, ecology and evolution of groundwater copepods
Copepod distributions at small spatial scales are most strongly affected by habitat type and heterogeneity, with sediment grain size and availability of organic matter being important habitat characteristics, and phylogenetic and distributional relicts and a high degree of endemism at different taxonomic levels are reflected. Expand
Groundwater biodiversity in Europe.
The broad-scale distribution of groundwater biodiversity across Europe is explored, focussing on obligate subterranean aquatic taxa, and a core of four hotspots emerged in all cases: one stretching across Slovenia and northeastern Italy, one in the French Pyrenees, two in Italy and one in Spain.

Longitudinal patterns of invertebrates in the hyporheic zone of a glacial river
Summary 1. Longitudinal changes in physicochemical factors and the composition of the invertebrate community were examined in the hyporheic zone of a glacial river (Val Roseg, Switzerland) over aExpand
Groundwater copepods: diversity patterns over ecological and evolutionary scales
Diversity patterns of copepod assemblages in groundwater are examined under both structural and functional profiles, as well as across a range of scales. Expand
Stygobiotic crustacean species richness: a question of numbers, a matter of scale
Assessing species richness in ground water at different spatial scales, and its contribution to overall freshwater species richness at the continental scale; analyzing the contribution of historical and ecological determinants in shaping spatial patterns of stygobiotic species richness across multiple spatial scales; and analysing the role of β-diversity in shaping patterns ofspecies richness at each scale analysed.

Geographic variation in range size and beta diversity of groundwater crustaceans: insights from habitats with low thermal seasonality
Aim Three broad mechanisms have been proposed to explain geographic variation in species range size: habitat area/heterogeneity, climate seasonality and long-term climate variability. However, itExpand
Biodiversity indicators in European ground waters: towards a predictive model of stygobiotic species richness
It is suggested that some taxonomic groups, mainly Copepoda and Amphipoda and, to a lesser extent, Oligochaeta and Gastropoda, were good biodiversity indicators in European groundwater ecosystems, however, the uneven distribution ofTaxonomic groups prevented selection of a common set of indicators for all six regions.
