Advancing Open‐Access Education for the Surgical Team Worldwide: The Development and Rollout of the United Nations Global Surgery Learning Hub (SURGhub)

World Journal of Surgery, Volume 49, Issue 7, Page 1700-1707, July 2025.
Training and professional development programmes for surgeons, anaesthetists, obstetricians and perioperative nurses in low‐resource settings are often constrained by lack of access to appropriate training materials. The United Nations Global Surgery Learning Hub (SURGhub) was launched on 28th June 2023 to address this need. SURGhub has enrolled 11,451

Spatially nested species distribution models (N‐SDM): An effective tool to overcome niche truncation for more robust inference and projections

Journal of Ecology, Volume 113, Issue 7, Page 1588-1605, July 2025.
N‐SDMs are key tools to develop untruncated regional climate change forecasts of species distributions at fine resolution over restricted extents. While several N‐SDM approaches were proposed, there is currently no universal solution suggesting that further developments and testing are crucial if we are to derive robust future projections of species ...

prioriactions: Multi‐action management planning in R

Methods in Ecology and Evolution, Volume 16, Issue 6, Page 1028-1039, June 2025.
Abstract Designing effective conservation strategies requires deciding not only where to locate conservation actions (i.e. which territorial units should be priortized), but also which type actions should be deployed. For most of conservation planning contexts, deciding where and what to do usually yields a complex and computationally challenging ...

Achieving sustainable water distribution through penalty‐free multi‐objective evolutionary design optimization

World Water Policy, Volume 11, Issue 2, Page 499-525, May 2025.
Abstract Water distribution networks are costly long‐term investments, prompting researchers to seek cost reduction and efficient design solutions using optimization techniques. In this context, the Penalty‐Free Multi‐Objective Evolutionary Algorithm (PFMOEA) is employed alongside pressure‐dependent analysis (PDA) to optimize water distribution systems
