The outbreak of Dutch elm disease in the 1970s ravaged European elm populations, killing more than 25 million trees in Britain alone; the greatest impact was on Ulmus procera, otherwise known as the English elm. Here we use molecular and historical information to show that this elm derives from a single clone that the Romans transported from Italy to the Iberian peninsula, and from there to Britain, for the purpose of supporting and training vines. Its highly efficient vegetative reproduction… Expand
Elm clone identification and the conundrum of the slow spread of Dutch Elm Disease on the Isle of Man
The susceptibility of U. × hollandica ‘Major’ to Dutch Elm Disease suggests that the unusually slow spread of the disease on the Island is unlikely to be the result of local disease resistance in the elm population. Expand
Extending glacial refugia for a European tree: genetic markers show that Iberian populations of white elm are native relicts and not introductions
This work addresses the status of the white elm, a European riparian tree species whose populations have been fragmented by human activity and is protected wherever it is considered native, arguing for immediate implementation of conservation measures in Spain and contiguous areas of southern France.

Seven Ulmus minor clones tolerant to Ophiostoma novo-ulmi registered as forest reproductive material in Spain
“Fuente Umbria”, tested over four consecutive years in Guadalajara and Palencia, was the Spanish clone with the most reliable tolerance level to O. novo-ulmi. Expand
Population clustering and clonal structure evidence the relict state of Ulmus minor Mill. in the Balearic Islands
Genetic markers are applied to assess whether field elm is or is not indigenous to the Balearic Islands, and principal coordinates analysis and Bayesian clustering methods reveal a strong genetic differentiation of theBalearic populations from the Iberian ones, and even among islands, which support their native origin.

The origin of clonal diversity and structure of Populus alba in Sardinia: evidence from nuclear and plastid microsatellite markers.
The uniqueness of the cpDNA haplotypes, the prevalence of clonality and the restricted number of genets recorded suggest that Sardinian white poplar could be a floristic relict of the native flora of the island, which has spread through available habitats on the island mainly by means of vegetative propagation and human activities. Expand
Combining the use of molecular techniques and archival documentary evidence to trace the origin of Populus alba in a Central Mediterranean archipelago
It is concluded that arrival of this clone in Malta through human introduction in the sixteenth century is the most likely explanation, since alternative scenarios like autovegetative propagation or arrival by seed seem highly unlikely. Expand
Breeding and scientific advances in the fight against Dutch elm disease: Will they allow the use of elms in forest restoration?
Recovering elm populations from the remaining diversity should build from genomic tools that facilitate achievement of resistant elm clones, and a deeper understanding of elm ecology is needed to understand their resilience to abiotic and biotic disturbances. Expand
High genetic differentiation in marginal populations of European white elm (Ulmus laevis).
The Finnish gene conservation strategy for U. laevis seems to be on a sound basis, and the observed genetic structure is consistent with the central-marginal hypothesis. Expand
Multiple ice-age refugia in a southern beech of South America as evidenced by chloroplast DNA markers
The results strongly suggest the persistence of the species in several ice-age refugia, possibly located in the Pacific Coastal Mountains from those coming from the easterly located Andes Mountains. Expand
Phylogeny, Biogeography, and Classification of the Elms (Ulmus)
Abstract A RAD-seq phylogeny is presented for the genus Ulmus, and a revised infrageneric classification is given, with keys, descriptions, and range maps for the subgenera and sections. TheExpand


Post-glacial re-colonization of European biota
Diversity from southern to northern Europe in the extent of allelic variation and species subdivision is seen; this is attributed to rapid expansion northward and the varied topography of southern refugia allowing populations to diverge through several ice ages. Expand
Phylogeographic structure of white oaks throughout the European continent.
The mapped distribution of the haplotypes indicates the probable routes of postglacial recolonization followed by oak populations that had persisted in southern refugia, especially in the Iberian peninsula, Italy and the Balkans. Expand
Female sterility in Ulmus minor (Ulmaceae): a hypothesis invoking the cost of sex in a clonal plant.
A high incidence of individuals with low seed set was found in two populations of the field elm Ulmus minor, a European tree that reproduces sexually and via vegetative propagation through root sprouting, helping to maintain female-sterile individuals with hermaphrodites. Expand
Roman vineyards in Britain: stratigraphic and palynological data from Wollaston in the Nene Valley, England
Stratigraphic and palynological evidence from trenches at Wollaston, Northamptonshire, suggest viticulture was extensively practised at this Roman site. It is argued that the apparent lack ofExpand
