Changes in the transformative potential of action proposals in Finnish Red Lists from 1986 to 2019

Conservation Biology, EarlyView.
Abstract Red lists provide critical knowledge regarding biodiversity decline, especially in Finland, where broad assessments have been made regularly since the 1980s. They deliver information on the threat status of species and ecosystems, propose actions to guide conservation policy, and have the potential to spur transformative change.

Uncovering correlates of decline and critical refuges for a threatened terrestrial mammal

Conservation Biology, EarlyView.
Abstract Globally, the geographic ranges of numerous species are contracting. Identifying spatiotemporal patterns of threat impact can illuminate why species decline in some parts of their range but persist in others. We developed a correlative approach to identify species’ response thresholds and locate ecological refuge areas associated with ...

Scientists’ warning on the global destruction of rock outcrop ecosystems

Conservation Biology, EarlyView.
Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...

To release or not to release? A call for caution when considering wildlife reintroductions

Conservation Science and Practice, EarlyView.
Conservation efforts often focus on flagship species and short‐term measures such as captive breeding and reintroductions, yet these approaches may benefit from being complemented with a broader view of the factors that influence long‐term recovery. Using examples from management programs in the Iberian Peninsula, we highlight the value of considering ...
