Predation pressure can be unexpectedly higher in urban areas compared to rural environments, showing up to 36% attack rates on prey.
Peak predation pressure occurs during summer months, especially from arthropods and mammals, contradicting prior urbanization hypotheses.
Study employed a sentinel approach with model caterpillars to assess predation rates in urban versus rural forests over a full season.
Findings highlight the complexity of ecological interactions in urban environments, calling for deeper exploration of urban wildlife behavior.

Observational analysis shows predation pressure can increase in urban areas, suggesting urban habitats may host hungrier predators.

Löveï et al. (2025) studied this question.
