Cryptic invasions are defined as the introduction and spread of non-native lineages within
the species' native range (intra-specific cryptic invasion) or the invasion of non-native …

Biological invasions create complex ecological and societal issues worldwide. Most of the
knowledge about invasions comes only from successful invaders, but less is known about …

Ecological speciation is the process by which reproductively isolated populations emerge as
a consequence of divergent natural or ecologically-mediated sexual selection. Most …

Colonization of new ecological niches has triggered large adaptive radiations. Although
some lineages have made use of such opportunities, not all do so. The factors causing this …

Populations occurring in similar habitats and displaying similar phenotypes are increasingly
used to explore parallel evolution at the molecular level. This generally ignores the …

The amphi‐boreal faunal element comprises closely related species and conspecific
populations with vicarious distributions in the North Atlantic and North Pacific basins. It …

Poleward range expansions are observed for an increasing number of species, which may
be an effect of global warming during the past decades. However, it is still not clear in how …

Abstract Willows (Salix: Salicaceae) form a major ecological component of Holarctic floras
and consequently are an obvious target for a DNA‐based identification system. We …

The complex of beech taxa in western Eurasia (Fagus sylvatica L. sl) represents one of the
most widespread broad-leaved trees in the temperate forests of the northern hemisphere …

Host resistance to parasites is a rapidly evolving trait that can influence how hosts modify
ecosystems. Eco-evolutionary feedbacks may develop if the ecosystem effects of host …
