Iron influence on dissolved color in lakes of the Upper Great Lakes States
PLOS ONE, 2019 Colored dissolved organic matter (CDOM), a major component of the dissolved organic carbon (DOC) pool in many lakes, is an important controlling factor in lake ecosystem functioning. Absorption coefficients at 440 nm (a440, m-1), a common measure of CDOM, exhibited strong associations with dissolved iron (Fediss) and DOC in 280 lakes of the Upper Great

Unraveling long-term changes in lake color based on optical properties of lake sediment
Science of The Total Environment, 2020 A number of boreal surface waters have become browner over the last two decades. Recovery from acid rain is regarded as an important driver for this lake color increase, indicating a general browner lake color in preindustrial times. However, the lack of long-term monitoring data makes it challenging to unravel historical changes in lake color. In this

An empirical evaluation of the nutrient‐color paradigm for lakes [PDF]
Limnology and Oceanography, 2008 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 lake trophic status. Our objectives were to quantify the combined influence of TP and color (Col) on lake trophic status, to determine if TP and Col had similar ...

Shifting patterns of lake color phenology in over 26,000 US lakes
, 2020 Lakes are often defined by seasonal cycles. The seasonal timing, or phenology, of many lake processes, such as primary productivity, are changing in response to human activities. However, long-term records exist for few lakes, and extrapolating patterns observed in these lakes to entire landscapes is exceedingly difficult using the limited number of in

Preference polymorphism for coloration but no speciation in a population of Lake Victoria cichlids [PDF]
Behavioral Ecology, 2007 Female mating preference based on male nuptial coloration has been suggested to be an important source of diversifying selection in the radiation of Lake Victoria cichlid fish. Initial variation in female preference is a prerequisite for diversifying selection; however, it is rarely studied in natural populations. In clear water areas of Lake Victoria,

In-Lake Processes Offset Increased Terrestrial Inputs of Dissolved Organic Carbon and Color to Lakes
PLoS ONE, 2013 Increased color in surface waters, or browning, can alter lake ecological function, lake thermal stratification and pose difficulties for drinking water treatment. Mechanisms suggested to cause browning include increased dissolved organic carbon (DOC) and iron concentrations, as well as a shift to more colored DOC.

Investigation into the dyeing of pre‐mordanted & cationised woven cotton fabric with cochineal
Coloration Technology, EarlyView.Abstract Dyeing cotton with natural dyes typically requires the pre‐application of a mordant, which enables better dye exhaustion from solution and ‘fixes’ the colorant in the fibre. The most common application system for cellulosic fibres is a combination of plant‐derived tannins and aluminium salts, such as aluminium sulphate.
