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.
Article Synopsis
- Predator-prey interactions are crucial for maintaining biodiversity but are challenging to observe in terrestrial arthropods using traditional methods.
- The study analyzed diet DNA from 173 invertebrate predators and their prey, revealing that prey size generally correlates with predator size, though some variations suggest other feeding behaviors like scavenging.
- Additionally, the research found that predator identity plays a more significant role than hunting strategies in determining predator-prey size ratios, highlighting the importance of body size and species identity in invertebrate food webs and their response to environmental changes.
Analogies for a No-Analog World: Tackling Uncertainties in Reintroduction Planning.
Trends Ecol Evol
July 2020
Species reintroductions involve considerable uncertainty, especially in highly altered landscapes. 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).
