“…Hence, resulting in the logical pattern observed, regarding the arsenic concentration between the three environments and the enrichment of genes displayed by these strains to face it. Since arsenic has been detected on the GSL basin in lower concentrations (0.4 – 95 μg/L for water) regarding the SH ( Waddell, 2004 ; Adams et al, 2015 ). Conversely, there are no reports for arsenic in EI.…”

“…Approximately 25% of all California gulls ( Larus californicus ) nest on the GSL [2,3], and half of North America's eared grebes ( Podiceps nigricollis ) spend the fall on the GSL eating brine shrimp ( Artemia franciscana ) and accumulating enough nutrients to fly to their wintering grounds in Mexico and California (USA) [4,5]. The GSL is a closed basin and accumulates contaminants from anthropogenic sources [6,7]. Indeed, elevated levels of Se and Hg have been detected in GSL water and biota [7,8].…”

We examined selenium and mercury concentrations in eared grebes (Podiceps nigricollis) that spent the fall of 2006 on the Great Salt Lake (UT, U.S.A.), where their diet consisted mainly of brine shrimp (Artemia franciscana). Selenium concentrations in livers varied based on when the grebes were collected (lower in September [mean +/- standard error, 9.4 +/- 0.7 microg/g dry wt] than in November [14.5 +/- 1.4 microg/g]), on where the birds were collected on the Great Salt Lake (Antelope Island, 8.6 +/- 0.5 +/- microg/g; Stansbury Island, 15.2 +/- 1.4 microg/g), and on the grebe's age (juveniles, 8.5 +/- 1.5 mcirog/g; adults, 15.8 +/- 1.3 microg/g), but not by sex. Selenium concentrations in blood differed only by collection site (Antelope Island, 16.8 +/- 2.3 microg/g; Stansbury Island, 25.4 +/- 3.0 microg/g). Mercury concentration in the blood of grebes varied by when the grebes were collected (September, 5.6 +/- 0.5 microg/g; November, 8.4 +/- 1.2 microg/g), where the birds were collected (Antelope Island, 4.3 +/- 0.5 microg/g; Stansbury Island, 10.1 +/- 2.6 microg/g), and the grebe's age (juveniles, 5.5 +/- 0.8 microg/g; adults, 8.4 +/- 1.0 microg/g), but not by sex. Selenium concentrations in blood were correlated with selenium concentrations in the liver and with mercury concentrations in both blood and liver. Body mass of grebes increased dramatically from September (381 +/- 14 g wet wt) to November (591 +/- 11 g). Body, liver, and spleen mass either were not correlated with selenium or mercury concentrations or the relationship was positive. These results suggest that high mercury and selenium levels were not preventing grebes from increasing or maintaining mass.

We examined selenium (Se) and mercury (Hg) concentrations in adult California gulls (Larus californicus) nesting on the Great Salt Lake, Utah, USA, during 2006 and 2007. During 2006, the mean Se concentration (+/- standard error) was 18.1 +/- 1.5 microg/g in blood on a dry-weight basis and 8.1 +/- 0.4 microg/g in liver. During 2007, Se concentrations were 15.7 +/- 1.5 microg/g in blood and 8.3 +/- 0.4 microg/g in liver; Hg concentrations were 2.4 +/- 0.3 microg/g in blood and 4.1 +/- 0.5 microg/g in liver. Gulls collected from a freshwater colony located within the watershed of the Great Salt Lake had similar levels of Se in the blood and liver as gulls collected on the Great Salt Lake but lower Hg concentrations. Body mass of adult gulls was not correlated with Se or Hg concentrations in their blood or liver. Selenium concentration in California gull eggs collected during 2006 was 3.0 +/- 0.10 microg/g. Of 72 eggs randomly collected from Great Salt Lake colonies, only one was infertile, and none of the embryos exhibited signs of malposition or deformities. We examined 100 newly hatched California gull chicks from Great Salt Lake colonies for teratogenesis; all chicks appeared normal. Hence, the elevated Se and Hg concentrations in adult gulls nesting on the Great Salt Lake did not appear to impair gulls' health or reproductive ability.
