To date, studies examining the impact of agriculture on freshwater systems have been
spatially confined (that is, single drainage basin or regional level). Across regions, there are …

A metacommunity is defined as a set of local communities that are connected by dispersal
and are controlled by environmental drivers operating at different spatial and temporal …

A knowledge of pre-disturbance conditions is important for setting realistic restoration targets
for lakes. For European waters this is now a requirement of the European Council Water …

We examined the impact of lake trophic state on the taxonomic and functional structure of
cladoceran communities and the role of nutrient loading in structuring both cladoceran and …

A variety of species richness measures have been used to assess the effects of
environmental degradation on biodiversity. Such measures can be highly influenced by …

The genus Brachysira is frequently encountered in the algal flora of oligotrophic freshwaters.
In order to re-evaluate its diversity in Irish waters, light and scanning electron microscopy …

Periphyton is increasingly used to assess the biological condition of lakes. The
predominance of relatively shallow exposed waterbodies in Ireland implies that epilithic …

Diatoms are powerful biomonitoring indicators for contemporary and past limnological
conditions, provided that their environmental optima are well-defined. Surface-sediment …

Anthropogenic eutrophication can significantly alter the nutrient balance in aquatic
environments. Changes in nutrient dynamics (nutrient loads and stoichiometry) have …

A survey of 60 high mountain lakes of Colombia's Eastern Range was performed to evaluate
the response of surface-sediment diatoms to environmental variables. In each one of these …
