Natural hybridization between introduced species and their native congeners occurs
frequently and can create serious conservation concerns. Ulmus pumila (Siberian elm) is an …

Ulmus pumila is an elm species, non‐native to the USA that hybridizes with Ulmus rubra. In
order to study the genetic structure and hybridization patterns between these two elm …

Ulmus pumila is considered an invasive tree in 41 of the United States. In this study, we
examined the extent of hybridization in naturalized populations of U. pumila, its impact on …

In response to the first Dutch elm disease (DED) pandemic, Siberian elm, Ulmus pumila,
was planted to replace the native elm, U. minor, in Italy. The potential for hybridization …

Elm breeding programs worldwide have relied heavily on Asian elm germplasm, particularly
Ulmus pumila, for the breeding of Dutch elm disease tolerant cultivars. However, the extent …

Abstract Background and Aims Ulmus minor has been severely affected by Dutch elm
disease (DED). The introduction into Europe of the exotic Ulmus pumila, highly tolerant to …

Ulmus laevis Pall. is a broad‐leaved deciduous tree with a central and eastern European
distribution. We describe the development of six polymorphic microsatellite markers for this …

Crossability barriers between the tetraploid Ulmus americana and five other diploid elm
species were investigated using both fluorescence and scanning electron microscopy. Both …

Forest pest epidemics are responsible for many population declines reported in forest trees.
While forest tree populations tend to be genetically diverse, in principle mortality resulting …

• Premise of the study: Exotic diseases are threatening many North American tree species,
and management of diseases requires understanding the biology of the host as well as the …
