This rule can be applied for species and populations within a species. The potential influence of body size on non-breeding distribution and habitat use at the intra-population level was investigated for southern giant petrels<jats:italic>Macronectes giganteus<\/jats:italic>(Gmelin) from Elephant Island, South Shetland Islands. The non-breeding distribution of 23 individuals was tracked, and total body length, culmen length, wing length, wing load and body mass were measured. Positions of core areas were used to estimate the latitudinal distribution of each individual. Smaller individuals were found to be associated more with lower latitudes, where warmer conditions and more coastal and productive waters prevail, whereas large males were associated more with higher latitudes, with colder conditions near sea ice caps, presumably feeding on carrion or preying on penguins. This association reflects a latitudinal gradient, with smaller individuals positioning themselves towards the north, and larger individuals towards the south. In this case, body size, individual distribution and habitat use were found to be associated, highlighting the importance of studying potential effects of individual body size on the ecology of seabirds.<\/jats:p>","DOI":"10.1017\/s0954102018000238","type":"journal-article","created":{"date-parts":[[2018,7,31]],"date-time":"2018-07-31T08:28:57Z","timestamp":1533025737000},"page":"271-277","update-policy":"http:\/\/dx.doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":6,"title":["Intra-population variability of the non-breeding distribution of southern giant petrels<i>Macronectes giganteus<\/i>is mediated by individual body size"],"prefix":"10.1017","volume":"30","author":[{"given":"Lucas","family":"Kr\u00fcger","sequence":"first","affiliation":[]},{"given":"Vitor H.","family":"Paiva","sequence":"additional","affiliation":[]},{"given":"Julia V.G.","family":"Finger","sequence":"additional","affiliation":[]},{"given":"Elisa","family":"Petersen","sequence":"additional","affiliation":[]},{"given":"Jos\u00e9 C.","family":"Xavier","sequence":"additional","affiliation":[]},{"given":"Maria V.","family":"Petry","sequence":"additional","affiliation":[]},{"given":"Jaime A.","family":"Ramos","sequence":"additional","affiliation":[]}],"member":"56","published-online":{"date-parts":[[2018,7,31]]},"reference":[{"key":"S0954102018000238_ref36","doi-asserted-by":"publisher","DOI":"10.1111\/oik.03698"},{"key":"S0954102018000238_ref25","doi-asserted-by":"publisher","DOI":"10.1111\/ecog.02209"},{"key":"S0954102018000238_ref12","doi-asserted-by":"crossref","DOI":"10.3354\/meps204279","article-title":"Foraging partitioning between giant petrels Macronectes spp. and its relationship with breeding population changes at Bird Island, South Georgia","volume":"204","author":"Gonz\u00e1lez-Sol\u00eds","year":"2000","journal-title":"Marine Ecology Progress Series"},{"key":"S0954102018000238_ref9","doi-asserted-by":"crossref","DOI":"10.1139\/z87-164","article-title":"Bergmann\u2019s rule is invalid","volume":"65","author":"Geist","year":"1987","journal-title":"Canadian Journal of Zoology"},{"key":"S0954102018000238_ref43","doi-asserted-by":"publisher","DOI":"10.3354\/meps08203"},{"key":"S0954102018000238_ref19","doi-asserted-by":"crossref","DOI":"10.1111\/j.1469-7998.1984.tb02343.x","article-title":"Breeding biology and population dynamics of giant petrels Macronectes at South Georgia (Aves: Procellariiformes)","volume":"203","author":"Hunter","year":"1984","journal-title":"Journal of Zoology"},{"key":"S0954102018000238_ref28","doi-asserted-by":"publisher","DOI":"10.1111\/j.1461-0248.2009.01281.x"},{"key":"S0954102018000238_ref31","doi-asserted-by":"publisher","DOI":"10.1098\/rspb.2004.2718"},{"key":"S0954102018000238_ref23","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2699.2003.00837.x"},{"key":"S0954102018000238_ref10","doi-asserted-by":"crossref","first-page":"247","DOI":"10.1111\/j.0030-1299.2004.12997.x","article-title":"Sexual size dimorphism in northern giant petrels: ecological correlates and scaling","volume":"105","author":"Gonz\u00e1lez-Sol\u00eds","year":"2004","journal-title":"Oikos"},{"key":"S0954102018000238_ref35","article-title":"Stable isotopes identify age- and sex-specific dietary partitioning and foraging habitat segregation in southern giant petrels breeding in Antarctica and southern Patagonia","volume":"159","author":"Rey","year":"2012","journal-title":"Marine Biology"},{"key":"S0954102018000238_ref2","doi-asserted-by":"crossref","DOI":"10.1111\/j.0014-3820.2004.tb01683.x","article-title":"Can intraspecific competition drive disruptive selection?
