Field Behavior Comparison of 8 Species of California Desert Ants
… californicus to bimodal to nocturnal in Pheidole barbata. Four aspects of surface activity, foraging, nest work, patrolling, and convening, also differed among species in hour and/or in relative proportion of such activity. Finally, interesting species differences were seen in climbing …

The evolution of caste-specific morphology and colony structure in ants
… chapter 2, I studied the species rich ant genus Pheidole to understand how worker morphology can adapt to environmental factors. Workers of Pheidole are almost always dimorphic, comprising a small minor subcaste and a major or soldier subcaste with a distinctively large head. Pheidole species …

Anting Behavior in Birds: Ant Selection and Effect of ant Chemistry on Feather Ectoparasites
… ants were preferred and <em>Pheidole</em> and <em>Crematogaster</em> ants were rejected. Preferred ants were significantly more active than ignored ants and lacked aggressive stinging and biting behaviors. Temperature and humidity did not affect anting displays, but …

The impact of pine plantations and alien invertebrates on native forest and fynbos invertebrate communities in Table Mountain National Park
… reiterative process and IndVal, two ant species (Pheidole capensis and Camponotus bertolinii) were selected as ecological indicators of restoration progress in fynbos following clear-felling of pine. Ants similarly have application for monitoring in other Mediterranean-type ecosystems impacted by …

Ant diversity and body size patterns across an altitudinal gradient in the Drakensberg Mountains, South Africa
… altitude within species for Plagiolepis sp. 45, Pheidole sp. 1, Monomorium sp. 12 and Tetramorium sp. 3. No body size relationship was established across species when using the across species method whereas the Stevens method indicates a decrease in body size with elevation. A number of factors …

Formigas bioindicadoras em floresta ecotonais: a resposta da mirmecofauna a diferentes distúrbios ambientais
… a alguns dos parâmetros granulométricos. Pheidole aff. reflexans foi relacionada a concentração de metais, particularmente Fe e Mn presentes em alta concentração nos solos atingidos pelo rejeito. Assim, verificamos que P. reflexans é uma boa indicadora de áreas com grande concentração de …

Effects of pine invasions on ground-dwelling ants on the southern slopes of the Swartberg Mountains
… generalist (17 species), particularly Pheidole sp. 1# (48 % of all individual ants) followed by nectar feeders (15 species), dominant generalists (2 species), specialist predators (2 species) and a seed harvester (1 species). In general, the non-dominant generalists preferred no-pine …

The consequences and implications of ecology on body size distributions in social insects
… (two distinct worker castes) big-headed ant (Pheidole megacephala) (Fabricius). This species has been introduced nearly worldwide including areas with species rich, competitively dominant ant fauna (e.g. Australia) and to islands that have no native ants (e.g. Hawaii). I utilize this variation …
