In recent years, the decline of many Arctic seabird populations has raised concerns about the potential role of sea-ice habitats on their demography. Spring sea-ice drives the dynamics of phytoplankton blooms, the basis of Arctic food webs, and changes in spring sea-ice have the potential to affect the demographic parameters of seabirds through bottom-up processes. To better understand the effects of spring sea-ice on Arctic seabirds, we investigated the influence of spring sea-ice concentration on the survival and breeding success of three seabird species with contrasted foraging strategies in two Svalbard fjords in the high Arctic. We examined these relationships using long-term demographic data (2005–2021) from black-legged kittiwakes (<i>Rissa tridactyla</i>), Brünnich guillemots (<i>Uria lomvia</i>), and little auks (<i>Alle alle</i>). Spring sea-ice concentration was positively related to both the survival and breeding success of little auks, suggesting a higher sensitivity of this species to spring sea-ice. By contrast, the two other species were not particularly sensitive to changes in spring sea-ice, even though a potentially spurious negative effect on the breeding success of black-legged kittiwakes was observed. Overall, the study suggests that spring sea-ice may be involved in the demography of Arctic seabirds, but probably does not play a major role.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Demographic responses of Arctic seabirds to spring sea-ice variations","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-17 01:32:53.339259","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Rissa tridactyla;Uria lomvia;Alle alle;survival;breeding success;sea-ice concentration;Svalbard;GULL PAGOPHILA-EBURNEA;THICK-BILLED MURRES;POPULATION-DYNAMICS;CLIMATE-CHANGE;URIA-LOMVIA;FORAGING BEHAVIOR;TOP PREDATOR;SURVIVAL;SVALBARD;IMPACTS","OtherDescriptors":null,"Notes":null,"AnaPub":2023,"MonPub":null,"DateUpdate":"2025-09-18","DateCreate":"2023-10-02","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000972947000001","VABBcode":null,"OpenAcc":1,"DOI":"10.3389/fevo.2023.1107992"},"refs":null,"anarec":{"AnaID":367718,"PubliDate":2023,"Pagination":"1107992","XtraPublOfAnaID":null,"ISBN":null,"Volume":"11","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":254552,"SerRR":"Frontiers in Ecology and Evolution.
