Yet mercury bioaccumulation in mesopelagic predators has been understudied. Northern elephant seals (\n                    <jats:italic>Mirounga angustirostris<\/jats:italic>\n                    ) biannually travel thousands of kilometres to forage within coastal and open-ocean regions of the northeast Pacific Ocean. We coupled satellite telemetry, diving behaviour and stable isotopes (carbon and nitrogen) from 77 adult females, and showed that variability among individuals in foraging location, diving depth and\n                    <jats:italic>\u03b4<\/jats:italic>\n                    <jats:sup>13<\/jats:sup>\n                    C values were correlated with mercury concentrations in blood and muscle. We identified three clusters of foraging strategies, and these resulted in substantially different mercury concentrations: (i) deeper-diving and offshore-foraging seals had the greatest mercury concentrations, (ii) shallower-diving and offshore-foraging seals had intermediate levels, and (iii) coastal and more northerly foraging seals had the lowest mercury concentrations. Additionally, mercury concentrations were lower at the end of the seven-month-long foraging trip (\n                    <jats:italic>n<\/jats:italic>\n                    = 31) than after the two-month- long post-breeding trip (\n                    <jats:italic>n<\/jats:italic>\n                    = 46). Our results indicate that foraging behaviour influences mercury exposure and mesopelagic predators foraging in the northeast Pacific Ocean may be at high risk for mercury bioaccumulation.\n                  <\/jats:p>","DOI":"10.1098\/rspb.2015.0710","type":"journal-article","created":{"date-parts":[[2015,6,17]],"date-time":"2015-06-17T04:59:46Z","timestamp":1434517186000},"page":"20150710","update-policy":"https:\/\/doi.org\/10.1098\/crossmark-policy","source":"Crossref","is-referenced-by-count":38,"title":["Marine foraging ecology influences mercury bioaccumulation in deep-diving northern elephant seals"],"prefix":"10.1098","volume":"282","author":[{"given":"Sarah H.","family":"Peterson","sequence":"first","affiliation":[{"name":"Department of Ecology and Evolutionary Biology, University of California, 100 Shaffer Road, Santa Cruz, CA 95060, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joshua T.","family":"Ackerman","sequence":"additional","affiliation":[{"name":"US Geological Survey, Western Ecological Research Center, Dixon Field Station, 800 Business Park Drive, Suite D, Dixon, CA 95620, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel P.","family":"Costa","sequence":"additional","affiliation":[{"name":"Department of Ecology and Evolutionary Biology, University of California, 100 Shaffer Road, Santa Cruz, CA 95060, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"175","published-online":{"date-parts":[[2015,7,7]]},"reference":[{"key":"e_1_3_7_2_2","doi-asserted-by":"publisher","DOI":"10.3109\/10408449509089885"},{"key":"e_1_3_7_3_2","doi-asserted-by":"publisher","DOI":"10.1579\/0044-7447(2007)36[12:EOEMOT]2.0.CO;2"},{"key":"e_1_3_7_4_2","doi-asserted-by":"publisher","DOI":"10.1002\/etc.5620161208"},{"key":"e_1_3_7_5_2","doi-asserted-by":"publisher","DOI":"10.1029\/2008GB003425"},{"key":"e_1_3_7_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.scitotenv.2009.08.036"},{"key":"e_1_3_7_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.marpolbul.2014.10.009"},{"key":"e_1_3_7_8_2","doi-asserted-by":"publisher","DOI":"10.1038\/nature13563"},{"key":"e_1_3_7_9_2","doi-asserted-by":"publisher","DOI":"10.1038\/ngeo1918"},{"key":"e_1_3_7_10_2","doi-asserted-by":"publisher","DOI":"10.1021\/cr050353m"},{"key":"e_1_3_7_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.scitotenv.2005.02.043"},{"key":"e_1_3_7_12_2","doi-asserted-by":"publisher","DOI":"10.1029\/2006GB002876"},{"key":"e_1_3_7_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.envres.2012.03.013"},{"key":"e_1_3_7_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.marchem.2004.02.025"},{"key":"e_1_3_7_15_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.0900711106"},{"key":"e_1_3_7_16_2","first-page":"135","volume-title":"Toxicology of marine mammals","author":"Das K","year":"2003"},{"key":"e_1_3_7_17_2","doi-asserted-by":"publisher","DOI":"10.2307\/2657207"},{"key":"e_1_3_7_18_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0036728"},{"key":"e_1_3_7_19_2","doi-asserted-by":"publisher","DOI":"10.1111\/1365-2435.12083"},{"key":"e_1_3_7_20_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1748-7692.1987.tb00318.x"},{"key":"e_1_3_7_21_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1101525108"},{"key":"e_1_3_7_22_2","doi-asserted-by":"publisher","DOI":"10.1038\/nature10082"},{"key":"e_1_3_7_23_2","doi-asserted-by":"publisher","DOI":"10.3354\/esr00254"},{"key":"e_1_3_7_24_2","volume-title":"Ecological geography of the sea","author":"Longhurst AR","year":"1998"},{"key":"e_1_3_7_25_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.scitotenv.2006.10.006"},{"key":"e_1_3_7_26_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00442-011-2202-y"},{"key":"e_1_3_7_27_2","doi-asserted-by":"publisher","DOI":"10.1897\/08-038.1"},{"key":"e_1_3_7_28_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF01189743"},{"key":"e_1_3_7_29_2","doi-asserted-by":"publisher","DOI":"10.1139\/f92-113"},{"key":"e_1_3_7_30_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0048-9697(98)00192-2"},{"key":"e_1_3_7_31_2","doi-asserted-by":"publisher","DOI":"10.1139\/z96-236"},{"key":"e_1_3_7_32_2","doi-asserted-by":"publisher","DOI":"10.1242\/jeb.045104"},{"key":"e_1_3_7_33_2","volume-title":"ETOPO1 1 Arc-minute global relief model: procedures, data sources and analysis","author":"Amante C","year":"2009"},{"key":"e_1_3_7_34_2","volume-title":"R: a language and environment for statistical computing","author":"R Development Core Team","year":"2012"},{"key":"e_1_3_7_35_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00265-010-1029-6"},{"key":"e_1_3_7_36_2","volume-title":"Model selection and multimodel inference: a practical information-theoretic approach","author":"Burnham KP","year":"2002"},{"key":"e_1_3_7_37_2","unstructured":"Husson F Josse J Le S& Mazet J. 2014 FactoMineR: multivariate exploratory data analysis and data mining with R .
