Native predators and exotic prey –an acquired taste?
2009年2月18日 · Native predators may be an important factor regulating not only native species, but also the long-term dynamics of invading species. Furthermore, the exotic prey/native predator system offers unique opportunities to study selection and contemporary evolution of adaptive traits in predator populations.
Reintroducing native predators improves antipredator responses …
2024年8月1日 · We tested the behavioural responses of two prey species, the burrowing bettong, Bettongia lesueur, and spinifex hopping mouse, Notomys alexis, to the reintroduction of a native predator, the western quoll, Dasyurus geoffroii, and determined whether exposure to a native predator improved their antipredator responses to introduced feral cats ...
We tested the behavioural re-sponses of two prey species, the burrowing bettong, Bettongia lesueur, and spinifex hopping mouse, Notomys alexis, to the reintroduction of a native predator, the western quoll, Dasyurus geoffroii, and determined whether exposure to a native predator improved their antipredator responses to introduced feral cats, Fel...
Native predators can learn new prey cues to overcome naivete …
2023年8月1日 · Native predators can defend against invasion by alien prey species through biotic resistance, but initial predator naivete towards novel alien prey can allow prey to establish. Here we test if predator naivete can be overcome via a learned association between novel prey cues and a food reward, and if this conditioning increases predator ...
Restoring native predators can control invasive species – if they …
2022年6月16日 · Naive prey and versatile predators. From wolves hunting non-native Corsican moufflon in the Mercantour mountains of southeastern France to red-banded snakes predating invasive bullfrogs in...
Native predators and exotic prey –an acquired taste?
2009年2月18日 · We propose that native predators could be important in regulating the long-term dynamics of invading species and, consequently, that the overexploitation of predators could facilitate biological invasions.
Predator–prey naïveté, antipredator behavior, and the ecology of ...
2010年4月12日 · We present a framework for explaining variation in predator invasion success and predator impacts on native prey that integrates information about predator–prey naïveté, predator and prey behavioral responses to each other, consumptive and non-consumptive effects of predators on prey, and interacting effects of multiple species interactions.
When native predators had access to non-native and native prey simultaneously, predator abun-dance increased significantly relative to pre-invasion abundance. Although non-native prey may have a lower per capita value than native prey, they seem to benefit native predators by serving as a supplemental prey resource. Keywords
Comparison of native and non‐native predator consumption …
2020年10月27日 · Novel predator–prey interactions can contribute to the invasion success of non‐native predators. For example, native prey can fail to recognize and avoid non‐native predators due to a lack of co‐evolutionary history and cue dissimilarity with native predators. This might result in a competitive advantage for non‐native predators.
How do native species respond to invaders? Mechanistic and
2015年3月15日 · Adaptive responses of native species are important in enabling their persistence in the face of unprecedented biotic exchange. In the present paper I discuss how native species respond to invasive species both from a mechanistic and trait-based perspective.
