Previous work has shown that sunlight exposure photo‐degrades aromatic DOM and leads to higher concentrations of LMW compounds (Anesio, Graneli, Aiken, Kieber, & Mopper, 2007; Bertilsson & Tranvik, 1998; Sulzberger & Durisch‐Kaiser, 2009). This process could lead to more bioavailable carbon and elevated CO 2 production (Lapierre et al., 2013; Lapierre & del Giorgio, 2014). However, growth of sediment bacteria in the clear lake may have been limited by the lower availability of N and P relative to C (per mass of DOC) (Figure ​ (Figure2d,e; 2d,e; Goldman et al., 1987; Reche et al., 1998; Smith & Prairie, 2004; Sterner, Elser, Fee, Guildford, & Chrzanowski, 1997; Sterner et al., 1998), despite the available LMW compounds. This nutrient limitation can explain why communities would have metabolically cycled C instead of allocating it to biomass, thus producing more CO 2 than the dark lake (del Giorgio & Cole, 1998; Hessen, 1992; Karlsson, Jansson, & Jonsson, 2002; Reche et al., 1998; Smith & Prairie, 2004; Zwart et al., 2016). Therefore, increasing t‐OM influx may have varied effects on in‐lake carbon cycling (Lapierre & del Giorgio, 2014). Photo‐mineralization can also produce up to 90% of CO 2 in aquatic systems, and may have accounted for some of the CO 2 observed in the clear lake pore water (Ward & Cory, 2016). This high rate of photo‐oxidation in the clear lake as opposed to the dark lake also altered the mesocosm pore water DOM quality, which may have shifted the composition of the clear lake bacterial community to taxa that were better able to degrade photoproducts, whereas the dark lake community may have been predisposed to degrade t‐OM (Judd et al., 2007; Lønborg et al., 2016; Sharpless et al., 2014; Ward & Cory, 2016). This is an Australian crime novel set in a small town in New South Wales during a particularly trying summer. As with any small town, everyone knows everyone, though there are plenty of secrets. The murder of a local girl forces everyone's business under the microscope, and this novel is as much about those secrets as it is about solving the mystery of who killed Rosalind Ryan.

The Dark Lake is the definition of a character-driven mystery. Gemma’s varied issues and history not only directly connect to the central mystery, they enhance the overall storyline. And Rose remains a haunting figure throughout. No passage seems pointless or wasted. Sarah Bailey has designed everything to perfection. The only reason The Dark Lake didn’t merit five stars is I was able to accurately predict the “whodunnit” about halfway through the book. Nevertheless, the story remained compelling and engaging.

Limnology and Oceanography, 57, 1042–1048. 10.4319/lo.2012.57.4.1042 Inputs of terrestrially derived organic matter (t‐OM) are a major driver in lake ecosystems, but the ecological consequences of changes in their quantity and quality remain poorly understood (Solomon et al., 2015). Nearly a third of all the terrestrial carbon (C) input into inland waters is buried into lake sediments (Tranvik et al., 2009). Much of this burial, especially of larger particulate material, occurs in nearshore environments of small lakes through mechanisms including sedimentation and flocculation, where heavier matter and coagulated dissolved organic matter (DOM) fall out of suspension and accumulate (von Wachenfeldt & Tranvik, 2008; Wurtsbaugh et al., 2002). However, littoral sediments remain understudied relative to pelagic environments, especially in the context of future changes to t‐OM exports. Terrestrial organic matter is increasingly exported into receiving waters, due to mechanisms including declines in anthropogenic sulfur deposition (Evans, Monteith, & Cooper, 2005; Monteith et al., 2007) and increases in terrestrial primary production (Freeman, Ostle, Fenner, & Kang, 2004) and soil decomposition (Findlay, 2005), and should thereby enhance sedimentation (Kritzberg et al., 2014; von Wachenfeldt, Sobek, Bastviken, & Tranvik, 2008). Additionally, northward shifts in deciduous forests (Boisvert‐Marsh, Perie, & Blois, 2014), and the spread of fires and insect outbreaks (Schindler & Lee, 2010), are expected to change the composition of t‐OM that will be buried into receiving waters (e.g., Jaffé et al., 2012). reflective pool that mirrors the teenage angst and plenty of underage boozing conjoined with adult complexities and emotions.Chemodiversity of dissolved organic matter in lakes driven by climate and hydrology.
