Survival Remains High in Griffon Vultures 40 Years After Reintroduction
Animal Conservation, Volume 29, Issue 3, Page 307-320, June 2026.The reintroduction of the Griffon vulture (Gyps fulvus) in French Grands Causses in 1981 is largely regarded as a significant translocation success. 40 years of quality data from intensive monitoring allows us to investigate the survival rates in this long‐lived population on the long term, but also to reflect on the crucial role of adaptive management

Computer Applications in Engineering Education, Volume 34, Issue 3, May 2026.ABSTRACT In engineering education, a “fidelity‐accessibility trade‐off” persists: accessible web simulations often lack physical accuracy, while complex industrial tools impose heavy cognitive loads. This hinders effective instruction in semiconductor physics in remote, hardware‐constrained environments.
