An assemblage-level comparison of genetic diversity and population genetic structure between island and mainland ant populations.

Island biotas provide unparalleled opportunities to examine evolutionary processes. Founder effects and bottlenecks, e.g.

Testing the effects of ant invasions on non-ant arthropods with high-resolution taxonomic data.

Invasions give rise to a wide range of ecological effects. Many invasions proceed without noticeable impacts on the resident biota, whereas others shift species composition and even alter ecosystem function. Ant invasions generate a broad spectrum of ecological effects, but controversy surrounds the extent of these impacts, especially with regard to how other arthropods are affected.

Floral visitation by the Argentine ant reduces bee visitation and plant seed set.

Ants often visit flowers, but have only seldom been documented to provide effective pollination services. Floral visitation by ants can also compromise plant reproduction in situations where ants interfere with more effective pollinators. Introduced ants may be especially likely to reduce plant reproductive success through floral visitation, but existing experimental studies have found little support for this hypothesis.
