open access: yes, 2011
The shape of the facial carina in Altastreplia is discussed. Although taxonomically useful, the protrudent form probably occurs by convergence in different species groups. Two species groups in which the carina is usually produced are revised.

Social‐ecological signatures in plant species composition across Swiss cities and urban green space types

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Cities can harbor greater plant diversity than other ecosystems, yet how city sociocultural factors may determine differences in plant composition across equivalent urban green space types remains understudied. Here, we compare plant communities in five main urban greenspace types across three Swiss cities representing the country's French (Geneva ...

Niche‐tracking as a collecting method: Habitat‐targeted search strategies for taxon‐focused botany

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity science depends on more than collecting plants—it depends on how we search for them. Although GPS and digital maps have transformed fieldwork, they can also encourage repeated visits to the same easy‐to‐access sites, leaving other habitats and populations unknown to science.
