<meta content="Tasmania is a natural laboratory for investigating the evolutionary processes of the Quaternary. It is a
large island lying 40-44 degrees S, which was repeatedly glaciated and linked to southeastern continental Australia
during the Quaternary. Climate change promoted both the isolation of species in glacial refugia, and an
exchange between Tasmanian and mainland floras. Eucalyptus is a complex and diverse genus, which has
increased in abundance in Australia over the past 100 kyr, probably in response to higher fire frequency.
Morphological evidence suggests that gene flow may have occurred between many eucalypt species after
changes in their distribution during the Quaternary. This paper summarizes recent genetic evidence for
migration and introgressive hybridization in Tasmanian Eucalyptus. Maternally inherited chloroplast
DNA reveals a long-term persistence of eucalypts in southeastern Tasmanian refugia, coupled with
introgressive hybridization involving many species. Detailed analysis of the widespread species Eucalyptus
globulus suggests that migration from mainland Australia was followed by introgression involving a rare
Tasmanian endemic. The data support the hypothesis that changes in distribution of interfertile species
during the Quaternary have promoted reticulate evolution in Eucalyptus." name="eprints.abstract" />

It is a
large island lying 40-44 degrees S, which was repeatedly glaciated and linked to southeastern continental Australia
during the Quaternary. Climate change promoted both the isolation of species in glacial refugia, and an
exchange between Tasmanian and mainland floras. Eucalyptus is a complex and diverse genus, which has
increased in abundance in Australia over the past 100 kyr, probably in response to higher fire frequency.
Morphological evidence suggests that gene flow may have occurred between many eucalypt species after
changes in their distribution during the Quaternary. This paper summarizes recent genetic evidence for
migration and introgressive hybridization in Tasmanian Eucalyptus. Maternally inherited chloroplast
DNA reveals a long-term persistence of eucalypts in southeastern Tasmanian refugia, coupled with
introgressive hybridization involving many species. Detailed analysis of the widespread species Eucalyptus
globulus suggests that migration from mainland Australia was followed by introgression involving a rare
Tasmanian endemic. The data support the hypothesis that changes in distribution of interfertile species
during the Quaternary have promoted reticulate evolution in Eucalyptus.</p></div><table style="margin-bottom: 1em" border="0" cellpadding="3" class="not_ep_block"><tr><th valign="top" class="ep_row">Item Type:</th><td valign="top" class="ep_row">Article</td></tr><tr><th valign="top" class="ep_row">Additional Information:</th><td valign="top" class="ep_row">The definitive version is available online at http://www.pubs.royalsoc.ac.uk/index.cfm?page=1085</td></tr><tr><th valign="top" class="ep_row">Keywords:</th><td valign="top" class="ep_row">glacial refugia; Eucalyptus; chloroplast; phylogeography; hybrid; Tasmania</td></tr><tr><th valign="top" class="ep_row">Subjects:</th><td valign="top" class="ep_row"><a href="http://eprints.utas.edu.au/view/subjects/270799.html">270000 Biological Sciences > 270700 Ecology and Evolution > 270799 Ecology and Evolution not elsewhere classified</a><br /><a href="http://eprints.utas.edu.au/view/subjects/270705.html">270000 Biological Sciences > 270700 Ecology and Evolution > 270705 Palaeoecology</a></td></tr><tr><th valign="top" class="ep_row">Collections:</th><td valign="top" class="ep_row">UNSPECIFIED</td></tr><tr><th valign="top" class="ep_row">ID Code:</th><td valign="top" class="ep_row">1778</td></tr><tr><th valign="top" class="ep_row">Deposited By:</th><td valign="top" class="ep_row"><span class="ep_name_citation"><span class="person_name">dr gregory j jordan</span></span></td></tr><tr><th valign="top" class="ep_row">Deposited On:</th><td valign="top" class="ep_row">03 Sep 2007</td></tr><tr><th valign="top" class="ep_row">Last Modified:</th><td valign="top" class="ep_row">12 Feb 2008 12:28</td></tr><tr><th valign="top" class="ep_row">ePrint Statistics:</th><td valign="top" class="ep_row"><a target="ePrintStats" href="/es/index.php?action=show_detail_eprint;id=1778;">View statistics for this ePrint</a></td></tr></table><p align="right">Repository Staff Only: <a href="http://eprints.utas.edu.au/cgi/users/home?screen=EPrint::View&eprintid=1778">item control page</a></p>
