Mapping of Forest Biodiversity Values: A Plural Perspective

The Millennium Ecosystem Assessment is built on a conceptual framework that links biodiversity to the services ecosystems provide to society. Based on this framework, we first compile market and non-market forest valuation studies and, secondly, explore the potential of an econometric modeling exercise by conducting a world wide meta-analysis. This exercise aims to highlight the mapping of biodiversity indicators and assesses their respective role on the valuation exercise. Our results show that biodiversity loss is having an effect on forest ecosystem values. In addition, these effects reveal to be dependent on the type of services and global geo-climatic regions

mRNA Coronavirus-19 Vaccine-Associated Myopericarditis in Adolescents: A Survey Study

In this survey study of institutions across the US, marked variability in evaluation, treatment, and follow-up of adolescents 12 through 18 years of age with mRNA coronavirus disease 2019 (COVID-19) vaccine-associated myopericarditis was noted. Only one adolescent with life-threatening complications was reported, with no deaths at any of the participating institutions
