Its two main clades diverged during the Messinian Salinity Crisis (~5.8 Mya).

The southern Iberian Peninsula is a hotspot of genetic diversity for wild grapevines, hosting three ancestral populations and multiple contact zones that acted as micro-refugia. The current genetic variability of Iberian wild grapevines is best explained by natural, climate-driven gene flow between African lineages with Middle Eastern origin and Iberian groups. These contacts were favoured by climatic conditions during the late Pleistocene (~21,000 years) and early Holocene (~8300 ","PeriodicalId":15299,"journal":{"name":"Journal of Biogeography","volume":"53 7","pages":""},"PeriodicalIF":3.5,"publicationDate":"2026-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jbi.70297","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148463180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The regions that become theoretically central and the systems interpreted comparatively reflect both biological complexity and the uneven historical contexts through which scientific knowledge is produced and legitimized. This essay examines how inherited narratives of discovery, uneven scientific investment, and structural inequalities in knowledge production have shaped marine biogeography, from its early formulations to contemporary comparative frameworks. Drawing on biogeographic theory and scholarship from the history of science, it argues that understanding biogeographic patterns requires attending not only to ecological and evolutionary processes but also to the epistemic contexts in which those patterns were first described and interpreted. Marine biogeography long operated under assumptions of oceanic homogeneity; as regional structure became increasingly recognized, some systems became established as central reference frameworks while others were more often interpreted comparatively. Re-examining such peripheral systems can strengthen biogeographic inference and contribute to more historically informed and geographically inclusive approaches to understanding marine biodiversity.</p>\u0000 </div>","PeriodicalId":15299,"journal":{"name":"Journal of Biogeography","volume":"53 7","pages":""},"PeriodicalIF":3.5,"publicationDate":"2026-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148462757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
