Forest tree hybrid zones provide a wealth of novel genetic variation that can be harnessed to
safeguard populations in changing climates. In the past 30 years, natural and artificial forest …

Hybridization is a potent evolutionary process that can affect the origin, maintenance, and
loss of biodiversity. Because of its ecological and evolutionary consequences, an …

The pantropical fern family Gleicheniaceae comprises approximately 157 species. Seven
genera are currently recognized in the family, although their monophyly is still uncertain due …

Natural systems of hybridizing plants are powerful tools with which to assess evolutionary
processes between parental species and their associated arthropods. Here we report on …

Hybridization is an important evolutionary force, because interspecific gene transfer can
introduce more new genetic material than is directly generated by mutations. Pinus …

Recently diverged species present particularly informative systems for studying speciation
and maintenance of genetic divergence in the face of gene flow. We investigated speciation …

To assess the possible impact of transgenic poplar plantations on the ecosystem, we
analyzed the frequency and distance of gene flow from a mature male transgenic Populus …

Diploid Alnus glutinosa s. str. and autotetraploid A. rohlenae form a narrow hybrid zone in a
study area in southern Serbia, which results in triploid hybrid formation. The vast majority of …

Invasive bighead (Hypophthalmichthys nobilis) and silver carp (H. molitrix) are
reproductively isolated in their native range, but form a bimodal, multigenerational hybrid …

The introduction and establishment of non-native plant pathogens into new areas can result
in severe outbreaks. Septoria leaf spot and canker caused by Sphaerulina musiva is one of …
