TL;DR: It is shown, by the experimental manipulation of dissolved inorganic 13C in two lakes, that internal primary production is insufficient to support the food webs of these ecosystems, and there is significant subsidy ofThese ecosystems by organic carbon produced outside their boundaries.

TL;DR: Responses of zooplankton, pelagic primary producers, planktonic bacteria, and CO2 exchange with the atmosphere were measured in four lakes with contrasting food webs under a range of nutrient enrichments during a seven-year period.

TL;DR: In this article, the authors measured allochthony (the terrestrial contribution of organic carbon to aquatic consumers) in two unproductive lakes (Paul and Peter Lakes in 2001), a nutrient-enriched lake (Peter Lake in 2002), and a dystrophic lake (Tuesday Lake, 2002) and three kinds of dynamic models were used to estimate allochthy: a process-rich, dual-isotope flow model based on mass balances of two carbon isotopes in 12 carbon pools; simple univariate time-series models driven by observed time courses of delta(13

TL;DR: In this paper, O2 and CO2 sondes were used to measure diel gas dynamics in the surface waters of 25 lakes and calculated gross primary production (GPP), R, and net ecosystem production (NEP 5 GPP 2 R).

TL;DR: In this article, the authors examined the importance of autochthonous versus allochthongous DOC in supporting the growth of pelagic bacteria by manipulating the 13 C content of auto-coated sources in a whole-lake experiment.
