Theory suggests that animals make hierarchical, multiscale resource selection decisions to address the hierarchy of factors limiting their fitness. Ecologists have developed tools to link population-level resource selection across scales; yet, theoretical expectations about the relationship between coarse- and fine-scale selection decisions at the individual level remain elusive despite their importance to fitness. With GPS-telemetry data collected across California, USA, we evaluated resource selection of mountain lions (Puma concolor; n = 244) relative to spatial variation in human-caused mortality risk.

Article Synopsis
- The study focuses on human-caused mortality in mountain lions across California, finding that this type of mortality is more significant than natural causes, despite legal protections against hunting.
- Researchers determined that human-caused mortality is additive to natural mortality, meaning it worsens population survival rather than just compensating for natural deaths.
- The risk of mortality for mountain lions is influenced by human development and community attitudes toward conservation, highlighting the importance of human impact on wildlife survival.
Jointly considering the ecology (e.g., habitat use) and genetics (e.
