New opportunities and challenges for conservation evidence synthesis from advances in natural language processing

Conservation Biology, Volume 39, Issue 2, April 2025.
Abstract Addressing global environmental conservation problems requires rapidly translating natural and conservation social science evidence to policy‐relevant information. Yet, exponential increases in scientific production combined with disciplinary differences in reporting research make interdisciplinary evidence syntheses especially challenging ...

Distributed non‐singular terminal sliding‐mode control for a synchronized motion of a Cartesian and a robotic manipulator

IET Control Theory &Applications, Volume 19, Issue 1, January/December 2025.
This study presents the design of a decentralized terminal sliding‐mode controller to solve the trajectory tracking problem of a composite robotic device made up of two‐dimensional Cartesian and multiple degrees‐of‐freedom robotic manipulators. The set of adaptive gains included in the controller implies enforcing the finite‐time convergence of the ...

Using comparative extinction risk analysis to prioritize the IUCN Red List reassessments of amphibians

Conservation Biology, Volume 38, Issue 6, December 2024.
Abstract Assessing the extinction risk of species based on the International Union for Conservation of Nature (IUCN) Red List (RL) is key to guiding conservation policies and reducing biodiversity loss. This process is resource demanding, however, and requires continuous updating, which becomes increasingly difficult as new species are added to the RL.
