Effect of harvester ants of the genus Pogonomyrmex on the soil seed bank around their nests in the central Monte desert, Argentina
(Wiley, 2014-10)
1. The abundance and composition of soil seed banks is a key determinant of plant community structure. Harvester ants can remove huge quantities of preferred seeds close to the nest affecting composition and spatial ...
Forager abundance and its relationship with colony activity level in three species of South American Pogonomyrmex harvester ants
(Springer, 2013-02)
The proportion of foragers in ant colonies is a fairly constant species-specific characteristic that could be determined by intrinsic or extrinsic factors. If intrinsic factors are relevant, species with similar life history ...
Foraging strategies and foraging plasticity in harvester ants (Pogonomyrmex spp., Hymenoptera: Formicidae) of the central Monte desert, Argentina
(Oesterreichische Gesell Entomofaunistik, 2015-09)
Foraging strategy determines the way harvester ants use space and therefore their access and impact on seed resources. In this study, we described the foraging strategy of three sympatric South American species of Pogonomyrmex ...
Behavioural flexibility does not prevent numerical declines of harvester ants under intense livestock grazing
(Wiley Blackwell Publishing, Inc, 2017-06)
1. Human-induced rapid environmental change may decrease food resources and create unfavourable conditions for native species. Organisms showing a flexible foraging behaviour can exploit novel or alternative foods and are ...
Foraging ecology of the giant Amazonian ant Dinoponera gigantea (Hymenoptera, Formicidae, Ponerinae): activity schedule, diet and spatial foraging patterns

EXPERIMENTAL INCIPIENT NEST TRANSPLANTS AND SURVIVORSHIP OF SOLENOPSIS-INVICTA BUREN (HYM, FORMICIDAE) IN BRAZIL
(Blackwell Wissenschafts Verlag Gmbh, 1993-09-01)
Transplants of incipient colonies of the fire ant, Solenopsis invicta into areas in which mature colonies had been eliminated did not result in higher rates of success than in areas in which mature colonies were present. ...
Chemical Composition of Metapleural Gland Secretions of Fungus-Growing and Non-fungus-growing Ants
(Springer, 2012-10-01)
The metapleural gland is exclusive to ants, and unusual among exocrine glands in having no mechanism for closure and retention of secretion. As yet, no clear conclusion has been reached as to the function of metapleural ...
