Multiple barriers maintain species boundaries in sympatric brood‐site deceptive Gastrodia orchids

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Gastrodia orchids are inconspicuous forest plants that lack chlorophyll and obtain carbon from fungi. Their dull‐colored, ground‐level flowers are often hidden among leaf litter, yet they rely on small flies for pollination. We show that two co‐occurring Gastrodia species remain distinct even though they share similar pollinators.

Needle in a haystack: Holocene history of European larch in Central Europe revisited

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Defining nativity of species is crucial for their management. However, this is a complex task, especially for species that have been used and spread by humans for a long time. We combined paleoecological records with extensive genetic data to investigate the Holocene history of European larch—a common and economically important tree species in Central ...

Female Melanostoma hoverflies pollinate Cypripedium yatabeanum through a Paphiopedilum‐like floral trap

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Conserving rare plants requires understanding the ecological interactions that enable their reproduction. Although most studied Cypripedium species are pollinated by bees, the pollinators of many slipper orchids remain undocumented. We show that Cypripedium yatabeanum is pollinated by female aphidophagous hoverflies despite sharing broadly similar ...
