When and why to give shorebirds a head start

Conservation Biology, EarlyView.
Abstract Headstarting is a translocation technique involving the hatching or rearing of wild eggs or young in captivity and the release of those individuals back to the wild at or before independence. It has been trialed as a conservation intervention for shorebirds over recent decades to improve the population trend of target populations by increasing

The collective application of shorebird tracking data to conservation

Conservation Biology, EarlyView.
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

An integrated approach to balance freshwater connectivity restoration and invasion risk

Conservation Biology, EarlyView.
Abstract Habitat fragmentation negatively affects many native migratory fish populations. However, this fragmentation can also prevent the spread and establishment of invasive species. We modified the dendritic connectivity index (DCI), a commonly used freshwater connectivity metric, to account for multiple invasive dispersal pathways in estimates of ...

Using incentive payments to promote human–carnivore coexistence

Conservation Biology, EarlyView.
Abstract For many large carnivores, minimizing the financial burden they impose on local people is critical to their conservation. Incentive‐based programs that provide people with financial benefits for taking pro‐conservation actions or achieving conservation goals are a promising tool for promoting human–carnivore coexistence. Although the number of
