The contribution of fish and their relative importance in the nutrient dynamics of lakes (sink vs. source) continue to be a topic of debate (Mehner et al. 2007; Wurtsbaugh 2007; Sereda et al. 2008b). ...

We calculated average aquatic dissolved organic carbon (DOC) age (the time span from soil discharge to
observation) in water from the inlets and outlets of two unproductive Swedish lakes at different...

A field study in a boreal lake using a remotely operated vehicle equipped with a camera established that falling
fish carcasses did not tend to be buried in sediments after deposition. Decomposition ...

The variability of surface water carbon dioxide concentration, or partial pressure (pCO2
), was studied in 11 lakes
of greatly varying size (2.4 ha up to 8 million ha) in Northwest Ontario, Canada. ...
