Current approaches to biodiversity conservation are largely based on geographic areas,
ecosystems, ecological communities, and species, with less attention on genetic diversity …

Adaptive radiations occur mostly in response to environmental variation through the
evolution of key innovations that allow emerging species to occupy new ecological niches …

Mimicry is a classic example of adaptation through natural selection. The traditional focus of
mimicry research has been on defence in animals, but there is now also a highly-developed …

The evolution of reproductive isolation is of central interest in evolutionary biology. In plants,
this is typically achieved by a combination of pre-and postpollination mechanisms that …

Episodes of rapid speciation provide unique insights into evolutionary processes underlying
species radiations and patterns of biodiversity. Here we investigated the radiation of …

Abstract Background Subtribe Orchidinae (Orchidaceae, Orchidoideae) are a nearly
cosmopolitan taxon of terrestrial orchids, comprising about 1800 species in 47 to 60 genera …

Floral isolation is an important component of pollinator‐driven speciation. However, up to
now, only a few studies have quantified its strength and relative contribution to total …

Background and aims Tribe Orchideae (Orchidaceae: Orchidoideae) comprises around 62
mostly terrestrial genera, which are well represented in the Northern Temperate Zone and …

Abstract Background and Aims Bee orchids (Ophrys) have become the most popular model
system for studying reproduction via insect-mediated pseudo-copulation and for exploring …

Pollination by sexual deception is arguably one of the most unusual liaisons linking plants
and insects, and perhaps the most illustrative example of extreme floral specialization in …
