Improving the use of expert opinion in disease risk analysis for conservation translocations

Conservation Biology, EarlyView.
Abstract Conservation translocations are subject to considerable uncertainty and risk, of which disease is one of the most recognized. To address disease risks, several protocols for qualitative disease risk analysis (qDRA) exist and are used for responsible conservation translocation planning.

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 ...

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 ...

Employing a Hysteresis Approach to Analyze Shifts in Tree Physiological Thresholds in Response to Drought

Plant, Cell &Environment, EarlyView.
ABSTRACT Drought‐induced tree mortality underscores the need for improved physiological models to predict tree responses to water stress. We employed a hysteresis modelling approach analyzing diel water absorption and desorption cycles to understand drought‐induced shifts in physiological thresholds.
