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 ...

Iflaviruses in arthropods: when small is mighty

open access: yesInsect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

The Late Agricultural Development of Central Arabian Oases—Archaeobotanical and Archaeozoological Studies of the al‐Kharj Oasis

open access: yesArabian Archaeology and Epigraphy, EarlyView.
ABSTRACT While oasis settlements emerged during the Bronze Age in Eastern and Northern Arabia, the settlement process in Central Arabia was different. Excavations at al‐Yamāma—main ancient settlement of the al‐Kharj oasis (Riyadh Province, KSA)—suggest that the latter did not emerge before the second half of the first millennium BCE.
