Priority resource access mediates competitive intensity between an invasive weevil and native floral herbivores

Exploitative competition between invasive herbivores benefits a native host plant.

Although biological invasions are of considerable concern to ecologists, relatively little attention has been paid to the potential for and consequences of indirect interactions between invasive species. Such interactions are generally thought to enhance invasives' spread and impact (i.e., the "invasional meltdown" hypothesis); however, exotic species might also act indirectly to slow the sprea...

Native herbivores and plant facilitation mediate the performance and distribution of an invasive exotic grass

1. Exotic plant species have become increasingly prominent features of ecological landscapes throughout the world, and their interactionswith native and exotic taxa in these novel environments may play critical roles inmediating the dynamics of such invasions. 2. Here, we summarize results from comparative and experimental studies that explore the effects of two factors – herbivory and facilita...

exploring interconnections between iranian efl teachers beleifs about the status of english as an international language (efl), use of mother tongue in efl classroom, and diffrences between native and non-native teachers of english

in one pole of the continuum of language learning, theoreticians and practitioners traditionally consider english as english as a second language or english as a foreign language. however, in the other pole of this continuum where english is thought of as the most effective tool for international communication, it is referred to as a lingua franca. those who favor an approach to english growing...

Invasion of a dominant floral resource: effects on the floral community and pollination of native plants.

Through competition for pollinators, invasive plants may suppress native flora. Community-level studies provide an integrative assessment of invasion impacts and insights into factors that influence the vulnerability of different native species. We investigated effects of the nonnative herb Lythrum salicaria on pollination of native species in 14 fens of the eastern United States. We compared v...
