An Osaka Metropolitan University researcher analyzed how population decline shapes residents’ life satisfaction in Japan’s shrinking small and medium-sized cities. Using data from 5,645 residents in the national 2024 Survey on Satisfaction and Quality of Life, the study found that population decline was associated with lower life satisfaction, but that specific contextual buffers became more important as shrinkage intensified. 

Drawing on examples from across the Great Lakes Basin, a new synthesis paper is examining the ecological structures and processes that help ecosystems withstand disturbances while continuing to provide the benefits that people and wildlife depend on. It highlights the importance of what ecologists call "portfolio effects": the stabilizing influence that arises when ecosystems contain a diversity of species, habitats, and ecological interactions operating across multiple levels of ecological organization. Much like a diversified financial portfolio reduces risk, ecological diversity can buffer ecosystems against environmental change and help maintain the production of natural resources over time.

Pollinators are important to humans and nature due to their role in ecosystem functioning and services. Research on the effects of pollinator management in protected areas is insufficient compared with that on farmlands and urban areas, potentially hindering appropriate policy implementation. To fill this gap, a new study investigated the impacts of pollinator-friendly management practices compared to conventional management in European protected areas.

This research was led by the HUN-REN Centre for Ecological Research in collaboration with 30 European institutes. Published in Conservation Biology, the synthesis examines whether pollinator-friendly management in protected areas has positive effects on vegetation, floral resources, and a broad range of pollinator groups. The findings show that pollinator-friendly management had mostly neutral and only a few positive effects on plants and pollinators.

A novel study shows that exposure to air pollution, especially fine particulate matter like dust, soot, and smoke (PM_2.5), is associated with increased disease activity and flare risk in rheumatoid arthritis (RA). The findings from an article in the Annals of the Rheumatic Diseases (ARD), The EULAR Journal, published by Elsevier, underscore the importance for healthcare providers and policymakers to recognize its impact on the management of RA.
