Management of invasive alien plants in forests: A global perspective

Journal of Applied Ecology, Volume 63, Issue 7, July 2026.
This review exposes urgent and critical knowledge gaps in forest IAP management, which need addressing to meet global targets for biodiversity and forest health. These gaps include highly uneven global research effort, narrow species focus, limited method replication, overlooked seasonal effects, and inconsistent cost reporting.

Seeing herbaria in a new light: leaf reflectance spectroscopy unlocks trait and classification modeling in plant biodiversity collections

New Phytologist, Volume 251, Issue 2, Page 811-829, July 2026.
Summary Reflectance spectroscopy is a rapid method for estimating traits and discriminating species. Spectral libraries from herbarium specimens represent an untapped resource for generating broad phenomic datasets across space, time, and taxa. We conducted a proof‐of‐concept study using trait data and spectra from herbarium specimens up to 179 yr old,

Defining and identifying relevant stakeholders to advance effective conservation

Conservation Biology, Volume 40, Issue 3, June 2026.
The challenge of defining stakeholders in environmental science and an approach for refining existing definitions. Abstract Stakeholder is a contested term that has spawned a multitude of ad hoc definitions. The ambiguity of these definitions has oftentimes impeded transdisciplinary research in environmental governance and conservation science because ...

Deconstructing Masculinity: A Mixed‐Methods Exploration of Health Access and Legal Implications Among Middle‐Aged Men in Yaoundé, Cameroon

Sexuality, Gender &Policy, Volume 9, Issue 2, May 2026.
ABSTRACT Masculinity significantly influences men's health‐seeking behaviors, yet its intersection with legal frameworks and healthcare access in Sub‐Saharan Africa remains underexplored. This mixed‐methods study investigates how gender norms and structural barriers influence healthcare experiences among 60 middle‐aged men (aged 30–60 years) in Yaoundé,

Deep Neural Networks for the Estimation of Masonry Structures Failures under Rockfalls

Geosciences, 2023
Although the principal aim of the rockfall management is to prevent rock boulders from reaching the buildings instead of the buildings resisting the boulder impacts, there usually exists a residual risk that has to be assessed, even when structural ...

Assessing the integration of social marketing principles in ivory demand management interventions in China and Southeast Asia

Conservation Biology, Volume 40, Issue 2, April 2026.
Abstract Consumer demand for ivory perpetuates the unsustainable and illegal killing of African elephants and other wildlife species. Interventions that aim to change consumer behavior are increasingly recognized as a crucial element of demand management. However, poor design and implementation have limited their effectiveness.
