Recent changes in production in oligotrophic Uinta Mountain lakes, Utah, identified using paleolimnology
oligotrophic Uinta Mountain lakes Utah
2014/11/28
We use multiple proxies from lake sediment records of six remote alpine lakes in the Uinta Mountains, Utah,
to investigate primary production and potential drivers of changes in trophic status over t...

Physical responses of small temperate lakes to variation in dissolved organic carbon concentrations
dissolved organic carbon concentrations lakes
2014/4/2
We used a mechanistic physical model to examine the effect of variability in dissolved organic carbon (DOC)
concentrations on the physical properties of small temperate lakes. The model was validated...
Characteristics and sources of chromophoric dissolved organic matter in lakes of the Yungui Plateau, China, differing in trophic state and altitude
Characteristics sources of chromophoric dissolved
2014/4/17
The high-mountain lakes on the Yungui Plateau in China are exposed to high-intensity ultraviolet radiation, and
contain low concentrations of chromophoric dissolved organic matter (CDOM). We determin...
Generalizations of the Wedderburn number: Parameterizing upwelling in stratified lakes
the Wedderburn number Parameterizing upwelling in stratified lakes
2014/4/17
The effect of lake geometry on wind-induced upwelling, in a two-layer stratified lake with a variable bottom slope and generic planar shape is investigated. (1) The traditional linearized classificati...
Drivers of metabolism and net heterotrophy in contrasting lakes
Drivers of metabolism net heterotrophy
2014/4/16
We investigated the influence of light, nutrients, and organic matter on gross primary production (GPP),
ecosystem respiration (R), and net ecosystem production (NEP 5 GPP 2 R) in a dystrophic forest...
Effects of fetch and dissolved organic carbon on epilimnion depth and light climate in small forest lakes in southern Sweden
ight climate epilimnion depth
2014/4/16
We sampled small (0.03 to 3.3 km2
surface area) forest lakes in southern Sweden during two summers to
investigate how concentration of dissolved organic carbon (DOC) and lake size influence epilimni...
Intermittent oxygen flux from the interior into the bottom boundary of lakes as observed by eddy correlation
Intermittent oxygen flux observed
2014/4/21
Turbulent oxygen transport from the overlying stratified water column into the bottom boundary layer (BBL)
on the slope of a medium-sized lake was investigated using the eddy correlation (EC) techniq...
Fish decomposition in boreal lakes and biogeochemical implications
Fish decomposition biogeochemical implications
2014/4/21
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 ...
Spatial variability of climate and land-use effects on lakes of the northern Great Plains
Spatial variability climate land-use on lakes of the northern Great Plains
2014/4/21
Evaluation of the effects of climate change and human activities on lakes requires improved understanding of how stressors interact and the degree to which individual sentinel lakes represent broad sp...

Food-web structure planktonic predator–prey relationships two eutrophic European lakes Stability constraints carbon fluxes
2014/4/21
The food webs in two eutrophic European lakes were analyzed with respect totheir stability characteristics.The food web during the summer in Lake Nesjøvatn (Norway) appeared to be stable; its res...
An empirical evaluation of the nutrient-color paradigm for lakes
empirical evaluation nutrient-color paradigm lakes
2014/4/21
We analyzed a diverse set of 1,646 north-temperate lakes to evaluate the nutrient-color paradigm that integrates total phosphorus (TP) and colored dissolved organic carbon to define laketrophic status...

Patterns and regulation of dissolved organic carbon: An analysis of 7,500 widely distributed lakes
Patterns regulation dissolved organic carbon 7,500 widely distributed lakes
2014/4/22
Dissolved organic carbon (DOC) is a key parameter in lakes that can affect numerous features, including microbial metabolism, light climate, acidity, and primary production. In an attempt to understan...
Nitrate-depleted conditions on the increase in shallow northern European lakes
Nitrate-depleted northern European lakes
2014/4/22
We determined relative nitrate-nitrogen (NO3-N) loss rates in 100 north-mid-European lakes from late spring to summer by using the exponential function N2 = N1e-k(t2 - t2), where N1 and N2 are NO3-N c...
