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. π

A 20-year study in the Arctic reveals widespread changes in vegetation due to rapid warming and environmental shifts. Data collected can help understand ecosystem changes and inform conservation efforts in these vulnerable regions. πΏ
What kills the virtually immortal palms of the Florida scrub? ($)
https://bsapubs.onlinelibrary.wiley.com/doi/abs/10.1002/ajb2.16234
4-decade-long findings reveal that surprisingly, Florida's 'immortal' palms rarely die. However, when they do, it's often due to factors such as extreme fires, lack of fire leading to shading, and varying habitat elevations. Fire-management planning could help secure their survival.π΄
Ecological restoration in Tibet optimises the cognitive structures of stakeholders on social-ecological systems (OA)
