Native and Non-Native Plants Provide Similar Refuge to Invertebrate Prey, but Less than Artificial Plants
Non-native species introductions are widespread and can affect ecosystem functioning by altering the structure of food webs. Invading plants often modify habitat structure, which may affect the suitability of vegetation as refuge and could thus impact predator-prey dynamics. Yet little is known about how the replacement of native by non-native vegetation affects predator-prey dynamics. We hypot...
متن کاملEffects of native and non-native vertebrate mutualists on plants.
Extinctions can leave species without mutualist partners and thus potentially reduce their fitness. In cases where non-native species function as mutualists, mutualism disruption associated with species' extinction may be mitigated. To assess the effectiveness of mutualist species with different origins, we conducted a meta-analysis in which we compared the effectiveness of pollination and seed...
متن کاملJasmonate-induced responses are costly but benefit plants under attack in native populations.
Herbivore attack is widely known to reduce food quality and to increase chemical defenses and other traits responsible for herbivore resistance. Inducible defenses are commonly thought to allow plants to forgo the costs of defense when not needed; however, neither their defensive function (increasing a plant's fitness) nor their cost-savings function have been demonstrated in nature. The root-p...
متن کاملMapping Non-native Plants Using Hyperspectral Imagery
One of the significant threats to global biodiversity and ecosystem functioning is the spread of invasive plant species (Mooney and Cleland, 2001). Continuing anthropogenic related disturbances such as land conversion, grazing, and habitat fragmentation, combined with international trade and climate change indicate that these trends are likely to continue (Zedler and Scheid, 1988). In this cont...
متن کاملINFLUENCE OF NON-NATIVE TROUT ON NATIVE NON-GAME FISH IN NEBRASKA HEADWATER STREAMS By
The direct predatory effects of introduced rainbow trout Oncorhynchus mykiss on native longnose dace Rhinichthys cataractae were examined using a series of in-stream enclosures to determine if presence, density, or acclimation period of rainbow trout influenced survival of longnose dace. The number of longnose dace remaining in enclosures over the first 72 hours after rainbow trout introduction...
