DNA can be preserved in marine and freshwater sediments both in bulk sediment and in
intact, viable resting stages. Here, we assess the potential for combined use of ancient …

Niche and neutral processes drive community assembly and metacommunity dynamics, but
their relative importance might vary with the spatial scale. The contribution of niche …

Plant-macrofossil analysis is being increasingly used in Quaternary science, particularly
palaeoecology and vegetation history. Although the techniques of macrofossil analysis are …

On the basis of long-term (1964-2011) research, we tested the hypothesis that the
zooplankton community has a highly indicative value in assessing the ecosystem and …

Abstract The Water Framework Directive requires that European Union (EU) Member States
ensure that their surface waters are in at least good ecological status by 2015 or at the latest …

Eutrophication is perhaps the most pervasive form of pollution. Here we first review its effects
on lake ecosystems based largely on modern ecological investigation. The longer time scale …

Based on our results, we propose the use of zooplankton abundance (density or biomass)
as an indicator to complement the information currently being used concerning the quality of …

Beginning in the late-1800s, gold mining activities throughout Nova Scotia, eastern Canada,
released contaminants, notably geogenic arsenic from milled ore and anthropogenic …

Diverse aquatic macrophyte communities represent an essential component of healthy
shallow lake ecosystems, and information on changes in macrophytes abundance and …

Eutrophication of lakes and reservoirs is a major water quality problem that poses significant
environmental, economic and social threats around the world. Monitoring and managing …
