Can you see the algae for the slime? Temporal patterns of biofilm food quality and quantity in lowland rivers

Ecosphere, 2023
Animals must invest some portion of their metabolism to activities related to physiological maintenance and the remainder to processes related to the production of new biomass for growth and reproduction.

Forested wetlands in freshwater and salt-water environments [PDF]

Limnology and Oceanography, 1988
A review of data from over 50 freshwater and about 50 salt‐water sites revealed that freshwater and salt‐water forested wetlands exhibit parallel responses to hydrologic factors. Greater ecosystem complexity and productivity are associated with higher hydrologic energy and more fertile conditions (riverine > fringe ≥ basin > dwarf = scrub ...

Phosphorus enrichment of the oligotrophic River Rede (Northumberland, UK) has no effect on periphyton growth rate

, 2014
Reducing phosphorus (P) loading to rivers is seen as a key mitigation measure to improve aquatic ecology and control excessive algal growth, as P is widely assumed to be the limiting nutrient in most rivers.

Seasonally resolved growth of freshwater bivalves determined by oxygen and carbon isotope shell chemistry [PDF]

, 2010
By means of a monitoring experiment in two rivers in the Netherlands, we establish a relationship between seasonally resolved growth rates in unionid freshwater bivalves and their environment.

Scale and watershed features determine lake chemistry patterns across physiographic regions in the far north of Ontario, Canada

Journal of Limnology, 2016
Changes in the far north of Ontario (>50°N latitude), like climate warming and increased industrial development, will have direct effects on watershed characteristics and lakes.

Climate change and its implications for Australia's freshwater fish

, 2011
Freshwater environments and their fishes are particularly vulnerable to climate change because the persistence and quality of aquatic habitat depend heavily on climatic and hydrologic regimes.
