Socio‐Economic Status and Non‐Native Species Drive Bird Ecosystem Service Provision in Urban Areas

Global Change Biology, Volume 31, Issue 7, July 2025.
Birds bring important benefits to people, like pest control and aesthetic enjoyment. We studied birds in cities across Spain and Portugal to see how income levels affect the benefits people get from nature. We found that higher income areas tended to have more bird species but, surprisingly, fewer of these benefits, while places with non‐native birds ...

FOGS: A SNPSTR Marker Database to Combat Wildlife Trafficking and a Cell Culture Bank for Ex‐Situ Conservation

Molecular Ecology Resources, Volume 25, Issue 4, May 2025.
ABSTRACT Illegal wildlife trade is a growing problem internationally. Poaching of animals not only leads to the extinction of populations and species but also has serious consequences for ecosystems and economies. This study introduces a molecular marker system that authorities can use to detect and substantiate wildlife trafficking.
