Local- Vs. Landscape-Scale Indirect Effects of an Invasive Weed on Native Plants
Insect-mediated indirect interactions between native plant species recently have been shown to be important determinants of plant performance in a number of ecological communities. However, the potential indirect effects of exotic plant invasion on native plant species are not well understood. We examined whether the presence or proximity of the targeted exotic weed, musk thistle, influences th...
متن کاملDifferent Growth Responses of an Invasive Weed and a Native Crop to Nitrogen Pulse and Competition
Resource pulses are a common event in agro-ecosystems. A pot experiment was conducted to assess the effects of nitrogen (N) pulses and competition on the growth of an invasive weed, Amaranthus retroflexus, and a native crop, Glycine max. A. retroflexus and G. max were planted in pure culture with two individuals of one species in each pot and in mixed culture with one A. retroflexus and one G. ...
متن کاملGastropod Seed Dispersal: An Invasive Slug Destroys Far More Seeds in Its Gut than Native Gastropods
Seed dispersal is one of the most important mechanisms shaping biodiversity, and animals are one of the key dispersal vectors. Animal seed dispersal can directly or indirectly be altered by invasive organisms through the establishment of new or the disruption of existing seed dispersal interactions. So far it is known for a few gastropod species that they ingest and defecate viable plant seeds ...
متن کاملEffects of simulated herbivory and resource availability on native and invasive exotic tree seedlings
The introduced tree, Sapium sebiferum, is a serious invader throughout the southeastern United States. Low herbivore loads, commonly attributed to high herbivore resistance, are assumed to give Sapium a competitive advantage over native vegetation. Because herbivory resistance is considered energetically expensive, we predicted that if Sapium experienced higher levels of damage its growth would...
