However, dispersal routes and directions of wet forest taxa into the South Pacific remain insufficiently known. We here aimed to establish the most likely routes and directions of plant dispersal into the Southwest Pacific islands.<\/jats:p><\/jats:sec><jats:sec><jats:title>Location<\/jats:title><jats:p>Southeast Asia, East Asia, Australia, Southwest Pacific.<\/jats:p><\/jats:sec><jats:sec><jats:title>Taxon<\/jats:title><jats:p><jats:italic>Dysoxylum<\/jats:italic> s.l.

Long\u2010distance dispersal is the main mechanism that led to the current distribution. Two dispersal pathways into the Southwest Pacific are identified, (1) through New Guinea and the Solomon Islands to Fiji, and (2) from New Zealand to Fiji. For both routes, Fiji was an important secondary source area for dispersal into the Southwest Pacific.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jbi.14606","type":"journal-article","created":{"date-parts":[[2023,4,19]],"date-time":"2023-04-19T11:40:17Z","timestamp":1681904417000},"page":"1257-1270","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["<scp>Sunda\u2013Sahul<\/scp> floristic exchange and pathways into the Southwest Pacific: New insights from wet tropical forest trees"],"prefix":"10.1111","volume":"50","author":[{"ORCID":"http:\/\/orcid.org\/0000-0001-5789-8673","authentic
