“…For example, yellow perch from acidic, high DOC lakes do not experience the same level of physiological disturbance observed in perch in anthropogenically acidified lakes (Nelson and Magnuson 1992). Both fish and benthic invertebrates can tolerate a lower pH in naturally acidic high DOC systems than they can in clear anthropogenically acidified systems, although DOC concentrations Ͼ20 mg liter Ϫ1 may be toxic (Collier et al 1990). In acidified lakes organisms are subjected to multiple stresses in addition to pH (Frost et al 1999), and DOC and pH have interactive effects on the toxicity of contaminants (Knulst 1992;Miskimmin et al 1992;Welsh et al 1993).…”

The primary interpretive paradigm used to study lakes is their trophic status. Oligotrophic lakes have low nutrient loading and low productivity, while eutrophic lakes have high nutrients and high productivity. The strong empirical relationship between nutrient loading and productivity is a valuable tool for teaching, for research, and for management of lakes. In order to incorporate the variety of other known anthropogenic impacts on lakes, however, lake characterization needs to extend beyond the nutrient-productivity paradigm. For example, acid precipitation, heavy metal and toxic organic contaminants, increases in UV radiation, and global warming are all recognized threats to lake ecosystems. One of the key characteristics of lakes that determines how they respond to disturbances such as these is their concentration of colored dissolved organic carbon (CDOC). Here we argue that a paradigm that includes CDOC (using the absorption coefficient at 320 nm as a proxy) as well as nutrients will be useful in predicting and understanding the response of lake ecosystems to multiple stressors. We propose to resurrect the CDOC axis that was proposed by investigators earlier this century and to extend it by adding some operational definitions to permit placing some of the major lake types on the axes in a way that will help us to better understand the structure, function, and response to disturbance of lake ecosystems that are subject to natural and anthropogenic environmental changes at the local, regional, and global scales. Data from a few diverse lakes and a successional sequence in Glacier Bay, Alaska, are used to illustrate the potential utility of the 2-axis model in separating lake types.The most commonly used paradigm for studying lake ecosystems defines lakes in terms of their trophic status. Lakes with low nutrients and low organic production are considered oligotrophic, while those with high nutrient inputs and organic productivity are eutrophic (Wetzel 1983). This paradigm has been adopted by the general ecological community as well as limnologists and is in general use in introductory ecology and limnology textbooks. The trophic status paradigm is supported by a particularly strong empirical relationship between chlorophyll and phosphorus (Vollenweider 1968;Dillon and Rigler 1974;McCauley et al. 1989), by comparative studies and whole-lake experiments that have clearly demonstrated the role of nutrients and grazers in eutrophication Pace 1984; Carpenter et al. 1991), and by the widespread success of remediation of AcknowledgmentsWe thank Dan Engstrom for stimulating discussions on the role of DOC in the succession of lakes in the Glacier Bay chronosequence, Sheri Fritz, Tom Frost, and Bruce Hargreaves for providing feedback on some of these ideas in their early stages of development, Dave Krabbenhoft for discussions on Hg, and Philip Singer and James Symons for introducing us to the literature on water treatment disinfection by-products and DOC.

“…[26,29,30]). Third, environmental acidification typically results in the increase of invertebrate predators [5,17] that can be ferocious predators of amphibian tadpoles. Hence, amphibians should experience simultaneous divergent selection via both acid stress and predation risk, and adaptation to both stressors should be highly beneficial to local populations inhabiting acidic wetlands.…”

Multifarious selection through environmental change: acidity and predator-mediated adaptive divergence in the moor frog (Rana arvalis)

et al. 2014

Environmental change can simultaneously cause abiotic stress and alter biological communities, yet adaptation of natural populations to co-changing environmental factors is poorly understood. We studied adaptation to acid and predator stress in six moor frog (Rana arvalis) populations along an acidification gradient, where abundance of invertebrate predators increases with increasing acidity of R. arvalis breeding ponds. First, we quantified divergence among the populations in anti-predator traits (behaviour and morphology) at different rearing conditions in the laboratory (factorial combinations of acid or neutral pH and the presence or the absence of a caged predator). Second, we evaluated relative fitness (survival) of the populations by exposing tadpoles from the different rearing conditions to predation by free-ranging dragonfly larvae. We found that morphological defences (relative tail depth) as well as survival of tadpoles under predation increased with increasing pond acidity (under most experimental conditions). Tail depth and larval size mediated survival differences among populations, but the contribution of trait divergence to survival was strongly dependent on prior rearing conditions. Our results indicate that R. arvalis populations are adapted to the elevated predator pressure in acidified ponds and emphasize the importance of multifarious selection via both direct (here: pH) and indirect (here: predators) environmental changes.

“…All three were small, naturally acidic streams on the Stockton plateau (average pH 4.5) with low dissolved metal concentrations. One stream (AMDI site score 0 0) contained a single taxon, the stonefly Spaniocercoides sp., which is known to be tolerant of low pH (Collier et al 1990;O'Halloran et al 2008). Two other streams had greater richness, three and four taxa respectively, and both streams contained Deleatidium spp., which is generally indicative of un-impacted streams (AMDI taxon indicator score 6).…”

“…However, studies of streams affected by AMD on the West Coast have reported the presence of a number of taxa more usually associated with unpolluted or 'natural' streams in waters with low pH because of high concentrations of organic acids (Winterbourn 1998;Suren & McKerchar 2001;Harding 2002). The tolerance of some taxa, such as the stonefly Spaniocercoides philpotti and caddisflies Psilochorema sp., to naturally acidic conditions in brownwater streams, high in dissolved organic carbon, may partially explain this observation (Collier et al 1990;O'Halloran et al 2008).…”

Acid Mine Drainage Index (AMDI): a benthic invertebrate biotic index for assessing coal mining impacts in New Zealand streams

Acid mine drainage (AMD) is a widespread phenomenon globally. Drainage into streams from coal mines often contains a cocktail of acidic waters high in dissolved metals, and consequently stream invertebrate communities may be severely impacted. Traditionally, the intensity of impacts has been assessed by combinations of water chemistry and benthic invertebrate metrics; however, a metric specifically designed for assessing mining impacts has not been developed. We propose a benthic invertebrate biotic index: the Acid Mine Drainage Index (AMDI), based on species presence data. The AMDI has been developed by associating water chemistry and benthic invertebrate community data collected from 91 sites. AMD indicator scores for 57 taxa were calculated using weighted averaging. Site scores can range from 0 (severely impacted) to 100 (unimpacted) and sites can be categorised as 'severely impacted', 'impacted' or 'unimpacted'. Comparisons between AMDI and traditional indices indicated the AMDI is more accurate at detecting mine drainage.
