Functional response predicts invasiveness but not trophic impact
Journal of Animal Ecology, EarlyView.This comparative analysis challenges the current paradigm that pre‐invasion functional response magnitude serves as a reliable predictor of post‐invasion ecological impact and highlights the need to distinguish between pre‐adaptation in native ranges and realized performance in invaded ecosystems.

Effects of temperature and browning on the functional response of a freshwater top predator
Journal of Animal Ecology, EarlyView.This study explores for the first time how temperature and browning affect the functional response of a freshwater piscivore, the northern pike. The authors find surprisingly weak effects of browning, challenging visual foraging theory. Pike displayed a rare dome‐shaped functional response in cold clear water, potentially driven by seasonal changes in ...

On traits matching and the modular organization of food web and occurrence networks
Journal of Animal Ecology, EarlyView.What mechanisms shape ecological networks? In Paraná River piscivores, species traits and abundance scaling promote modular structures. Our findings reveal how communities self‐organize and highlight the conditions needed to sustain them. Abstract Modularity and nestedness have been observed recurrently across different ecological networks, including ...

Egg oiling as an effective management technique for limiting reproduction in an invasive passerine
Avian Conservation and Ecology, 2019 The House Sparrow (Passer domesticus), native to Europe and Asia, has been introduced globally and is now one of the most ubiquitous birds in the world. In North America, these invasive passerines compete with native species for nest cavities, which are ...

Journal of Animal Ecology, EarlyView.We provide a framework for extending commonly used integrated population models to a metapopulation framework for testing novel ecological hypotheses about how changing environmental conditions within and among subpopulations drive changes in animal abundance.

Journal of Animal Ecology, EarlyView.Partial seasonal migration is rarely considered in a metapopulation context. Here, Haaland et al. use an eco‐evolutionary model revealing how partially migratory metapopulations may arise and be maintained, and how seasonal migrants may cause effects of local extreme climatic events to percolate through metapopulations across diverging temporal and ...
