Metabolic and physiochemical responses to a whole-lake experimental increase in dissolved organic carbon in a north-temperate lake
Over the last several decades, many lakes globally have increased in dissolved organic carbon (DOC), calling into question how lake functions may respond to increasing DOC. Unfortunately, our basis for making predictions is limited to spatial surveys, modeling, and laboratory experiments, which may not accurately capture important whole-ecosystem processes. In this article, we present data on m...
متن کاملLinking allochthonous dissolved organic matter and boreal lake sediment carbon sequestration: The role of light-mediated flocculation
We measured flocculation of dissolved organic carbon (DOC) in the water from a humic lake (DOC 5 14.9 mg C L21) and from an adjacent mire (DOC 5 25.7 mg C L21), in in situ enclosure experiments with different light regimes. Light stimulated the formation of organic particles in both waters, and organic particle formation was observed at all incubation depths, even in the dark controls. Producti...
متن کاملSpatial and Temporal Variation in the Dietary Ecology of the Glaucous-winged Gull Larus Glaucescens in the Pacific Northwest
The widespread distribution of contaminants in marine environments is of global concern, particularly for those compounds that do not readily degrade and are relatively volatile, such as persistent organic pollutants (POPs) (Jones & De Voogt 1999, Tanabe 2004). POPs are a group of lipophilic compounds that accumulate in fatty tissues of organisms, leading to their bioaccumulation and biomagnifi...
متن کاملSynchronous variation of dissolved organic carbon and color in lakes
Temporal variation in dissolved organic carbon (DOC) and water color (light absorption at 440 nm) was measured in 20 lakes in northern Michigan that varied in DOC, pH, morphometry, and relative productivity as indicated by chlorophyll and total phosphorus (TP). Monthly observations during May–August over 6 yr revealed that DOC and color varied by 6and 28-fold among lakes and varied substantiall...
متن کاملRelative importance of CO2 recycling and CH4 pathways in lake food webs along a dissolved organic carbon gradient
Terrestrial ecosystems export large quantities of dissolved organic carbon (DOC) to aquatic ecosystems. This DOC can serve as a resource for heterotrophic bacteria and influence whether lakes function as sources or sinks of atmospheric CO2. However, it remains unclear as to how terrestrial carbon moves through lake food webs. We addressed this topic by conducting a comparative lake survey in th...
