In this study, we show that the Atlantic Bluefin tuna (ABFT,\n            <jats:italic>Thunnus thynnus<\/jats:italic>\n            ), an oceanic predatory species exhibiting highly migratory behavior, large population size, and high potential for dispersal during early life stages, displays significant genetic differences over space and time, both at the fine and large scales of variation. We compared microsatellite variation of contemporary (\n            <jats:italic>n<\/jats:italic>\n            = 256) and historical (\n            <jats:italic>n<\/jats:italic>\n            = 99) biological samples of ABFTs of the central-western Mediterranean Sea, the latter dating back to the early 20th century. Measures of genetic differentiation and a general heterozygote deficit suggest that differences exist among population samples, both now and 96\u201380 years ago. Thus, ABFTs do not represent a single panmictic population in the Mediterranean Sea. Statistics designed to infer changes in population size, both from current and past genetic variation, suggest that some Mediterranean ABFT populations, although still not severely reduced in their genetic potential, might have suffered from demographic declines. The short-term estimates of effective population size are straddled on the minimum threshold (effective population size = 500) indicated to maintain genetic diversity and evolutionary potential across several generations in natural populations.\n          <\/jats:p>","DOI":"10.1073\/pnas.0908281107","type":"journal-article","created":{"date-parts":[[2010,1,5]],"date-time":"2010-01-05T02:36:36Z","timestamp":1262658996000},"page":"2102-2107","update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":96,"title":["Spatio-temporal population structuring and genetic diversity retention in depleted Atlantic Bluefin tuna of the Mediterranean Sea"],"prefix":"10.1073","volume":"107","author":[{"given":"Giulia","family":"Riccioni","sequence":"first","affiliation":[{"name":"Department of Biology and Evolution, University of Ferrara, 44100 Ferrara, Italy;"}]},{"given":"Monica","family":"Landi","sequence":"additional","affiliation":[{"name":"Department of Experimental Evolutionary Biology, University of Bologna, 40126 Bologna, Italy;"}]},{"given":"Giorgia","family":"Ferrara","sequence":"additional","affiliation":[{"name":"Department of Experimental Evolutionary Biology, University of Bologna, 40126 Bologna, Italy;"}]},{"given":"Ilaria","family":"Milano","sequence":"additional","affiliation":[{"name":"Department of Experimental Evolutionary Biology, University of Bologna, 40126 Bologna, Italy;"}]},{"given":"Alessia","family":"Cariani","sequence":"additional","affiliation":[{"name":"Department of Experimental Evolutionary Biology, University of Bologna, 40126 Bologna, Italy;"}]},{"given":"Lorenzo","family":"Zane","sequence":"additional","affiliation":[{"name":"Department of Biology, University of Padova, 35121 Padova, Italy; and"}]},{"given":"Massimo","family":"Sella","sequence":"additional","affiliation":[{"name":"Institute Center for Marine Research, 52210 Rovinj, Croatia (formerly Istituto Italo-Germanico di Biologia Marina\/Deutsch-Italienisches Institut f\u00fcr Meersbiologie, Rovigno, Italy)"}]},{"given":"Guido","family":"Barbujani","sequence":"additional","affiliation":[{"name":"Department of Biology and Evolution, University of Ferrara, 44100 Ferrara, Italy;"}]},{"given":"Fausto","family":"Tinti","sequence":"additional","affiliation":[{"name":"Department of Experimental Evolutionary Biology, University of Bologna, 40126 Bologna, Italy;"}]}],"member":"341","published-online":{"date-parts":[[2010,4]]},"reference":[{"key":"e_1_3_3_1_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-294X.2007.03477.x"},{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1467-2979.2008.00299.x"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1017\/S0016672300034455"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1420-9101.2005.00885.x"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1467-2979.2008.00303.x"},{"key":"e_1_3_3_6_2","volume-title":"Dynamic Changes in Marine Ecosystems: Fishing, Food Webs and Future Options","year":"2006","unstructured":"Dynamic Changes in Marine Ecosystems: Fishing, Food Webs and Future Options (National Academy Press, Washington, DC, 2006)."},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1038\/nature03581"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.1135347"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1523-1739.2008.00901.x"},{"key":"e_1_3_3_10_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.0709034105"},{"key":"e_1_3_3_11_2","doi-asserted-by":"publisher","DOI":"10.1038\/nature03463"},{"key":"e_1_3_3_12_2","doi-asserted-by":"publisher","DOI":"10.1093\/jhered\/esl046"},{"key":"e_1_3_3_13_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.1161473"},{"key":"e_1_3_3_14_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1467-2979.2005.00197.x"},{"key":"e_1_3_3_15_2","doi-asserted-by":"publisher","DOI":"10.1080\/10641260701484135"},{"key":"e_1_3_3_16_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1467-2979.2008.00311.x"},{"key":"e_1_3_3_17_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00227-006-0447-5"},{"key":"e_1_3_3_18_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00227-008-1058-0"},{"key":"e_1_3_3_19_2","volume-title":"Report of the 2006 Atlantic Bluefin Tuna Stock Assessment Session (SCRS\/2006\/013).
