“…The high 222 Rn concentrations observed in the western (September 2013) and southwestern (May 2014) parts in the survey area on both sampling occasions (September 2013 and May 2014) indicate high submarine groundwater seepage in these areas. Although there has been very limited information on how submarine groundwater discharge affect aquatic food webs in the world, increase in primary production were shown around submarine groundwater bents in Delaware Bay (Miller and Ullman, 2004) and in Lake Huron (Sanders et al, 2011). The correspondence of high chlorophyll-a concentrations with 222 Rn concentrations in the present study also indicate linkage between submarine groundwater nutrients and aquatic food webs.…”

“…Freshwater provided from terrestrial to coastal areas can be divided into surface water (river water) and groundwater. There have been far more studies on how the variability in surface water affects fisheries production in aquatic ecosystems than the groundwater supply (Hwang et al, 2005;Miller and Ullman, 2004;Sanders et al, 2011). In several recent studies, groundwater discharge has been estimated to approximate or even exceed 50% of total freshwater input to a bay (Valiela et al, 1990;Slomp and van Cappellen, 2004).…”

“…65% of total dissolved inorganic phosphorus provided through all freshwater) was provided through submarine groundwater, which is higher in nutrients, especially phosphorus (Sugimoto et al, 2015). High levels of submarine groundwater seepage have been shown to correspond with elevated primary production in coastal waters of the world (Hwang et al, 2005;Miller and Ullman, 2004;Sanders et al, 2011;Sugimoto et al, 2015). To date, however, there is still limited information on the effects of submarine groundwater on higher trophic levels such as secondary consumers (Sanders et al, 2011).…”

Generally, migratory fishes are able to visit multiple ecosystems and/ or areas for feeding and therefore it is difficult to quantify the relative contribution of each ecosystem or area to their productivity.…”

Recently discovered submerged sinkholes in Lake Huron are high-sulfur, lowoxygen extreme environments for microbial life. In order to understand the relationship between the physical environment, photophysiology and community composition, we measured the physical conditions, photophysiological indices, and genetic diversity at 3 microbial mat sites bathed in high conductivity groundwater under a natural light gradient during 2012 and 2013. A strong seasonal trend prevailed at all sites, characterized by decreased photosynthetic yield (F v '/F m '; 0.25 to 0.40) during the summer (April to August) and increased yield (0.70 to 0.75) during the winter (November to March). Chlorophyll a content varied seasonally in a similar manner to photosynthetic yield. All sites were dominated by > 80% abundance of one cyanobacterial group, most closely related to Phormidium sp. Phycobilins (phycocyanin and phycoerythrin) were consistently higher in concentration than chlorophyll. Photosynthetic yield was statistically indistinguishable between sites, suggesting that these mat communities are able to acclimate across a wide range of photosynthetically active radiation (PAR). Interestingly, these cyanobacteria carried out oxygenic photosynthesis in the presence of in vitro H 2 S, further suggestive of their versatile photophysiologies under variable redox conditions. Collectively, our study provides insight into the adaptive capabilities of cyanobacteria by revealing how they photophysiologically respond to changes in light climate and redox conditions, and are thereby able to inhabit a wide range of physico-chemical environments. Such versatile physiologies may have enabled their ancestors to thrive across a range of habitats on early Earth.

Nitrogen and carbon stable isotopes (δ N, δ C) are commonly used to understand mercury (Hg) bioaccumulation and biomagnification in freshwater food webs. Though sulfur isotopes (δ S) can distinguish between energy sources from the water column (aqueous sulfate) and from sediments to freshwater organisms, little is known about whether δ S can help interpret variable Hg concentrations in aquatic species or food webs. Seven acidic lakes in Kejimkujik National Park (Nova Scotia, Canada) were sampled for biota, water, and sediments in 2009 and 2010. Fishes, zooplankton, and macroinvertebrates were analyzed for δ S, δ N, δ C, and Hg (methyl Hg in invertebrates, total Hg in fishes); aqueous sulfate and profundal sediments were analyzed for δ S. Within lakes, mean δ S values in sediments and sulfate differed between 0.53‰ and 1.98‰, limiting their use as tracers of energy sources to the food webs. However, log-Hg and δ S values were negatively related (slopes -0.14 to -0.35, R 0.20-0.39, p < 0.001-0.01) through each food web, and slopes were significantly different among lakes (analysis of covariance, lake × δ S interaction term p = 0.04). Despite these relationships, multiple regression analyses within each taxon showed that biotic Hg concentrations were generally better predicted by δ N and/or δ C. The results indicate that δ S values are predictive of Hg concentrations in these food webs, although the mechanisms underlying these relationships warrant further study.
