The interactions between ants and certain sap-feeding insects in the order Hemiptera are
classic examples of food-for-protection mutualisms. In these associations, herbivorous …

The impact of the imported fire ant (IFA) is complex, in large part, because several very
different species of “Fire Ants” have invaded and one of these has two forms, all of which are …

In multiply invaded ecosystems, introduced species should interact with each other as well
as with native species. Invader–invader interactions may affect the success of further …

A recently introduced, ecologically dominant, exotic ant species, Nylanderia fulva, is
invading the Southeastern United States and Texas. We evaluate how this invader impacts …

Alien ants are among the most deleterious predatory invertebrates causing havoc to native
biodiversity including negative effects on other ant species, other invertebrates and …

Invasions by nonnative insect species can massively disrupt ecological processes, often
leading to serious economic impacts. Previous work has identified propagule pressure as …

The functions and compositions of symbiotic bacterial communities often correlate with host
ecology. Yet cause–effect relationships and the order of symbiont vs. host change remain …

Resource availability can determine an organism's investment strategies for growth and
reproduction. When nutrients are limited, there are potential tradeoffs between investing into …

Positive interactions are ubiquitous processes within ecological communities that influence
patterns of species diversity and ecosystem functioning. By reducing abiotic stress, such as …

Abstract 1 Primary resources may affect the structure of species assemblages in upper
trophic levels of food webs. These bottom-up effects may involve important ecological …
