Aero‐breakup of droplets: Recent progress and outlook
This work systematically reviews the recent progress of droplet aero‐breakup studies. The discussion covers the research history, theoretical framework, new breakup mode discoveries, influence of droplet fluid properties, scenarios of multi‐droplet and droplet cloud, and finally, an outlook for future explorations is presented. Abstract Aero‐breakup of

Biodiversity can influence forest productivity, but this does not necessarily translate into higher provision of wood‐based Nature's contributions to people (NCP), as only a subset of the wood produced is used for each NCP. Biodiversity–NCP relationships therefore require further assessment.
