Gender dimorphic species flower earlier than cosexuals (OA)

https://besjournals.onlinelibrary.wiley.com/doi/full/10.1111/1365-2745.14188

Flowering, crucial for plant reproduction and its interaction with pollinators and climate, happens earlier in gender dimorphic plants compared to cosexual ones, even after considering other factors. This could be due to sexual selection favoring early male flowering and sexual conflict.

Floral Resources used by Bees in Urban Areas: The Case of Geneva, Switzerland (OA)

https://www.frontiersin.org/articles/10.3389/fevo.2023.1199438/abstract

Urban areas are potentially valuable refuges for bees, demonstrated by a new study showing that diverse indigenous meadows in cities can help ensure their survival. Cities can offer equally diverse pollen sources as rural areas, and meadows can be richer in bee and plant species than commonly used seed mixes. 🐝

Pollen Carryover, Pollinator Movement, and Spatial Context Impact the Delivery of Pollination Services in Apple Orchards

https://esajournals.onlinelibrary.wiley.com/doi/abs/10.1002/eap.2917

Researchers highlighted the importance of considering pollen carryover & pollinator movement patterns when assessing pollinator performance. They discovered pollination effectiveness varies greatly across different orchard layout. It's not only about frequency of visits or pollen deposit, but bees' movement plays crucial role too🐝
