Strengthening women's empowerment and gender equality in fragile contexts towards peaceful and inclusive societies: A systematic review and meta‐analysis

Campbell Systematic Reviews, Volume 18, Issue 1, March 2022., 2022
Abstract Background Across the globe, gender disparities still exist with regard to equitable access to resources, participation in decision‐making processes, and gender and sexual‐based violence. This is particularly true in fragile and conflict‐affected settings, where women and girls are affected by both fragility and conflict in unique ways.

Strongly structured populations and reproductive habitat fragmentation increase the vulnerability of the Mediterranean starry ray Raja asterias (Elasmobranchii, Rajidae)

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 32, Issue 1, Page 66-84, January 2022., 2022
Abstract The Mediterranean starry ray (Raja asterias) populations within the Mediterranean Sea are susceptible to high rates of bycatch in the multispecies trawl fisheries. Understanding its population structure and identifying critical habitats are crucial for assessing species vulnerability and setting the groundwork for specific management measures ...
