An extensive survey of wild bee and bee–plant networks in Sardinia (Italy) highlights high species richness and diversity, particularly in mainland agroecosystems. All interaction networks were highly specialized, modular, and not nested, indicating potential ecological vulnerability, though varying across sites and on a temporal scale.

This study investigated whether small, artificial ponds deployed within a commercial farm can function as microhabitats supporting diverse invertebrate communities. We recorded 40 invertebrate taxa from nine orders utilising the ponds, including honey bees, lady beetles and spiders, as well as three species of eristaline hoverflies.
