Article Synopsis
- Nigeria has diverse ecosystems, which significantly affect how reptiles, like the red-headed rock agama, evolve and adapt in different habitats.
- Research revealed distinct genetic lineages in the agama, closely linked to ecological regions, geographic isolation, and environmental factors like climate conditions.
- The study suggests that habitat fragmentation, particularly in western Nigeria, poses threats to these lizards, indicating an urgent need for conservation efforts.
The global decline of cheetah Acinonyx jubatus and what it means for conservation.

Article Synopsis
- Establishing protected areas (PAs) is crucial for protecting biodiversity, but it's not enough for many wide-ranging species like the cheetah, which faces significant survival challenges.
- The global cheetah population is only about 7,100 individuals, primarily located outside PAs, where they encounter various threats.
- To effectively conserve species like the cheetah, there needs to be a shift in conservation strategies towards holistic approaches that encourage coexistence and protection across larger landscapes, rather than relying solely on PAs.
The African lion has declined to <35,000 individuals occupying 25% of its historic range. The situation is most critical for the geographically isolated populations in West Africa, where the species is considered regionally endangered. Elevating their conservation significance, recent molecular studies establish the genetic distinctiveness of West and Central African lions from other extant African populations.
