Freshwater ecosystems are strongly influenced by weather extremes such as heatwaves
(HWs), which are predicted to increase in frequency and magnitude in the future. In addition …

Limnology has traditionally been a science of temperate regions. Long-term studies are not
common in tropical regions despite the number of large tropical lakes that constitute a …

Eutrophication substantially influences the community structure of aquatic organisms and
has become a major threat to biodiversity. However, whether eutrophication is linked to …

It is now well known that heterotrophic bacteria account for a large portion of total uptake of
both phosphate (60% median) and ammonium (30% median) in freshwaters and marine …

We analyzed heterotrophic, pelagic bacterial production and specific growth rate data from
57 studies conducted in fresh, marine and estuarine/coastal waters. Strong positive …

There has been an explosion of research on marine microbial foodweb processes in the
past decade. Today it is widely accepted that about 50% of the primary production in marine …

Humic Substances color all waters more or less brown. Their concentrations exceed all
carbon of living organisms by at least one order of magnitude. Opposite to former …

Heterotrophic bacteria are a key component driving biogeochemical processes in aquatic
ecosystems. In 1998, we examined the role of heterotrophic bacteria by quantifying plankton …

The relationships between long-term surface average concentrations of humic acids
measured as water colour, dissolved organic carbon (DOC) or Secchi disk transparency and …

Enrichment experiments with P and N were conducted in humic Lake Örträsket in northern
Sweden. The composition of the microplankton community showed a dominance by …
