Policy Studies Journal, Volume 54, Issue 2, May 2026.ABSTRACT Intergovernmental grants stimulate the diffusion of policy reforms, as the federal government provides states with a financial incentive to adopt policies aligned with federal priorities. Less is known about the extent to which these grants also stimulate horizontal diffusion across states.

Journal of Applied Ecology, Volume 63, Issue 4, April 2026.This study highlights the importance of integrating cross‐realm connectivity and threat propagation when designing new or expanding existing networks of conservation areas, such as the Natura 2000 European network of protected areas. These findings emphasize the need for multirealm planning that supports species persistence, protects transitional ...

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We

Journal of Applied Ecology, Volume 63, Issue 3, March 2026.Tree‐health policies must balance identifying likely entry points and deployment of traps, targeted information campaigns and surveillance subsidies for land managers. Our unique, cross‐disciplinary approach can be applied to other pest/pathogen systems to inform tree‐health plans and how to balance resources.

New Phytologist, Volume 249, Issue 3, Page 1509-1526, February 2026.Summary Plastic responses of plants to their environment vary as a result of genetic differentiation within and among species. To accurately predict rangewide responses to climate change, it is necessary to characterize genotype‐specific reaction norms across the continuum of historic and future climate conditions comprising a species' range. The North
