Article Synopsis
- * Researchers used two methods, diet DNA analysis and stable isotope analysis, to examine trophic responses in top and intermediate predators across environments with varying productivity levels.
- * Findings reveal that while top predators' trophic position increases with productivity, their diet composition remains stable; in contrast, intermediate predators show significant dietary shifts towards more predatory prey in high-productivity areas, underscoring the importance of predator identity in ecological responses.
Predator-prey interactions shape ecosystems and can help maintain biodiversity. However, for many of the earth's most biodiverse and abundant organisms, including terrestrial arthropods, these interactions are difficult or impossible to observe directly with traditional approaches. Based on previous theory, it is likely that predator-prey interactions for these organisms are shaped by a combination of predator traits, including body size and species-specific hunting strategies.

Historical, geographic, and taxonomic analogies can help reduce this uncertainty by enabling conservationists to better assess habitat suitability in proposed reintroduction sites. We illustrate this approach using the example of the California grizzly, an iconic species proposed for reintroduction.

Anecdotal biting reports, collection records, and regular captures in black-light traps showed the species was present before rat eradication. Since then, there have been no biting reports and no captures over 2 years of extensive trapping (black-light and scent traps).
