Evaluating synthetic substitutes to reduce illegal harvesting and support species recovery

Conservation Biology, EarlyView.
Abstract Providing synthetic substitutes is a widely promoted strategy to shift consumer demand away from wildlife products derived from threatened species. Yet, there is little evidence on whether product substitution prevents illegal or unsustainable harvesting and contributes to the recovery of threatened populations.

Assessing differences among elasmobranch nurseries to aid conservation based on a genomics framework

Conservation Biology, EarlyView.
Abstract Elasmobranch nurseries often differ in environmental conditions, demographics, and use patterns. These differences affect the distribution of genetic variation among nurseries. However, conservation and management strategies often fail to account for such differences because they are difficult to characterize.

Impact of global change on the distribution of mountain mammals and birds

Conservation Biology, EarlyView.
Abstract Climate change and land‐use changes are key drivers of global biodiversity loss. Many species are shifting to higher elevations or latitudes in response to global warming, often encountering unfavorable land‐use conditions during the shift. These changes can lead to reduced range size and increased extinction risks, particularly for mountain ...
