Experimental studies and research focused on the native range ecology of invasive ants will be especially valuable contributions to this field of study.

- 2000
Aproximately 50,000 nonindigenous (non-native) species are estimated to have been introduced to the United States, many of which are beneficial but have caused major economic losses in agriculture, forestry, and several other segments of the US economy, in addition to harming the environment.
ENVIRONMENTAL AND ECONOMIC COSTS ASSOCIATED WITH NON-INDIGENOUS SPECIES IN THE UNITED STATES

- Environmental Science
- 1999
Invading non-indigenous species in the United States cause major environmental damages and losses adding up to more than $138 billion per year and about 42% of the species on the Threatened or Endangered species lists are at risk primarily because of non-Indigenous species.
Managing the whole landscape: historical, hybrid, and novel ecosystems
The reality confronting ecosystem managers today is one of heterogeneous, rapidly transforming landscapes, particularly in the areas more affected by urban and agricultural development. A landscape…
Invasive Ants: Unwanted Partners in Ant-Plant Interactions?
- L. Lach
- Environmental Science
- 24 January 2003
The potential for effects of invasive ants on plants to counteract, and the complexity and context-dependency that are hallmarks of ant-plant interactions generally, preclude drawing simple conclusions about the net impacts of invasive ant on plants.
Argentine ants displace floral arthropods in a biodiversity hotspot

The displacement of floral arthropods by Argentine ants may have far-reaching consequences for this biodiversity hotspot and other regions that are rich in insect-pollinated plants.
A mutualism with a native membracid facilitates pollinator displacement by Argentine ants.

Though Argentine ants were not associated with a decline in P. nitida seed set or ovule predation, declines in generalist insect pollinators may have ramifications for the 83% of fynbos plants that are insect pollinated.
Floral visitation patterns of two invasive ant species and their effects on other hymenopteran visitors

Abstract 1. Floral nectar of the native Hawaiian ‘ōhi’a tree, Metrosideros polymorpha, is an important food source for several native honeycreepers and yellow‐faced bees, Hylaeus spp., but is also…
Interference and exploitation competition of three nectar-thieving invasive ant species

Compared the nectar-thieving behavior of three widespread invasive ant species in inflorescences of the native Hawaiian ‘ōhi’a tree, an important food source for native fauna, Anoplolepis gracilipes may be effective at both interference and exploitation competition against other nectarivores, L. humile and P. megacephala may be relatively weak at both types of competition.
