Stable Isotope Analysis as a Tool to Prevent Illicit Wildlife Trade of Songbirds in Brazil

Animal Conservation, EarlyView.
Feather isotopes provide clear differences between wild and captive songbirds in Brazil. Combining multiple isotopes improved classification accuracy and revealed individuals falsely declared as captive‐bred. These results demonstrate the potential of isotope analysis to detect wildlife laundering in the bird trade.

Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

Using customs data to understand overlooked trade in non‐CITES birds between Africa and Asia

Conservation Biology, EarlyView.
Abstract The international trade in live birds poses risks to animals, people, and biodiversity. To effectively mitigate these risks, decision‐makers require information on the volume, dynamics, and direction of trade. Despite Africa once being the largest exporter of birds by region, very little data exist on recent trade in live birds not listed on ...

A framework for maximizing the benefit from retaining regrowth on private land

Conservation Biology, EarlyView.
Abstract Conservation interventions often have lower‐than‐desired positive impacts, as revealed by retrospective counterfactual‐based evaluations. To address this, a prospective counterfactual‐based approach can be used to estimate potential benefits and design conservation interventions to maximize outcomes. We developed a framework for estimating the
