First-year survival of Lake Sturgeon reintroduced to the Maumee River First-year survival of Lake Sturgeon reintroduced to the Maumee River

ObjectiveLake Sturgeon Acipenser fulvescens have experienced large population declines due to overfishing, habitat degradation, and pollution. Due to these factors, Lake Sturgeon were extirpated from the Maumee River watershed (Ohio, United States). In 2018, a 20-year reintroduction program began that aims to establish a self-sustaining population in the Maumee River. To understand the...

Wake Atoll: Evaluation of plant biosecurity Wake Atoll: Evaluation of plant biosecurity

Introduced organisms can cause substantial effects across most landscapes. Island ecosystems, especially tropical islands, are at elevated risk from introduced organisms. The risks are even higher for tropical islands with moderate or high levels of transit, yet this can be minimized by application of appropriate biosecurity requirements. In this study, we examined the potential for non...
