Aquifers and groundwater-dependent ecosystems (GDEs) are facing increasing pressure
from water consumption, irrigation and climate change. These pressures modify groundwater …

Aim An intensively debated issue in macroecology is whether unicellular organisms show
biogeographic patterns different from those of macroorganisms. One aspect of this debate …

Groundwater dependent ecosystems (GDEs) include valuable ecosystems such as springs,
wetlands, rivers, lakes and lagoons. The protection of these systems and services they …

Aim We examined the relative contributions of spatial gradients and local environmental
conditions to macroinvertebrate assemblages of boreal headwater streams at three hierarchical …

… For example, trends in taxon richness were higher at sites with higher maximum mean
temperatures (t max mean) but lower at sites with higher rates of temperature increase (t max sl.; b…

Multiscale determinants of diversity and the relationship between regional (RSR) and local
richness (LSR) have recently attracted increased attention, yet such studies on stream …

… Species richness was higher in the restored than natural streams in 1991 (t = 2.73, P = 0.017)
but did not differ among the channel types on the latter sampling time (t = 0.44, P = 0.667; …

An important goal for community ecology is the characterization and prediction of changes
in community patterns along environmental gradients. We aimed to identify the major …

… efficiency was not quite significant (planned comparison test t = 2·06, P = 0·069, df = 7).
Natural streams retained leaves more efficiently than the restored streams (t = 3·87, P = 0·040, df …

Many natural ecosystems are heterogeneous at scales ranging from microhabitats to landscapes.
Running waters are no exception in this regard, and their environmental heterogeneity …
