“…Further, litter ant colonies never appear to achieve the permanence of many large soil nesting species. Nests of twigs and leaves are fragile and temporary, subject to predation and disturbance (Yamaguchi 1992), forcing litter colonies to move periodically (Byrne 1994;Herbers 1986;Ward 1981). Life for a litter ant colony may be more unpredictable than for their large soil nesting counterparts.…”

Springer-Verlag 1995 M i c h a e l K a s p a r i • M a r g a r e t M . B y r n e A b s t r a c t The allocation to growth, defense and reproduction varies in social insects within a species' life cycle and between species. A life cycle model (Oster and Wilson 1978) generally failed to predict caste allocation in small litter-nesting colonies of NeotropicalPheidole. Two of its assumptions were often invalid:food was unlikely to be limiting in four of five populations, and sexual biomass production accelerated, not decelerated, with colony size in three of five populations. One of five Pheidole populations studied had higher caste ratios (soldiers/workers) in reproductive colonies as predicted, and in no species did caste functions conform to predictions. We also adapted three models from plant defense theory to study betweenspecies patterns of caste allocation. Among 12 litter Pheidole the amount of sterile biomass devoted to soldiers varied from 18 to 62%. Queen size, growth rate, and soldier investment positively covaried. Only one model, the cost of replacement hypothesis (McKey 1979), correctly predicted that species with costly female alates invest more in defense. The two hypotheses linking apparency to defense may also be valid if fast, growing colonies are more likely to attract the attention of predators. K e y w o r d s C a s t e •

“…If litter Pheidole occupy small, breakable nests, making colonies vulnerable to predators and random catastrophe (Byrne 1994;Herbers 1986;Yamaguchi 1992), then colonies may be perishing before reaching a size where resources limit colony growth.…”

“…Many studies, which have investigated niche partitioning in ant communities, revealed that competition can result: (1) in direct antagonistic behaviour (Savolainen and Vepsäläinen 1988;Yamaguchi 1992;Retana and Cerdµ 1995;Punttila et al 1996;, (2) in temporal segregation (Baroni Urbani and Aktaç 1981;Marsh 1988;Fellers 1989;Deffernez et al 1990;Cros et al 1997;de Biseau et al 1997;Retana and Cerdµ 2000;Albrecht and Gotelli 2001;Campos and Schoereder 2001), (3) in spatial segregation by microhabitat differentiation (Punttila et al 1996, Johnson 2000, or (4) in different foraging strategies (Traniello 1983(Traniello , 1987Jones and Sherman 1990;Perfecto 1994;de Biseau et al 1997;Sanders and Gordon 2000).…”

Sympatry and allopatry in two desert ant sister species: how do Cataglyphis bicolor and C. savignyi coexist?

Two extremely morphologically similar sister species of desert ants, Cataglyphis bicolor and C. savignyi, exhibit broadly overlapping distributional ranges within Tunisia. In order to analyse the microhabitats of C. bicolor and C. savignyi within the sympatric and allopatric areas of both ant species, the plant species located at 113 different nest sites of the two ant species were determined. In the sympatric area, the two species exhibit a clear-cut nest site segregation. This is not the case in the allopatric areas. Hence the two species differentiate their microhabitat only when they are sympatric. The plant species associated mainly with the nest sites of C. bicolor indicate that this species prefers a type of vegetation that needs irrigation. This is in contrast to the nest sites of C. savignyi, which are usually found around plants that characterize typical dry steppe areas. As the ants' foraging paths recorded in the sympatric area reveal, C. bicolor performs significantly shorter foraging runs with respect to both length and time, and covers a much smaller foraging range than C. savignyi does. This result reflects the fact that the microhabitat occupied by the colonies of C. bicolor is richer in food abundance. When direct interspecific interactions were investigated by placing a bait midway between two heterospecific nests, C. bicolor foragers dominated over those of C. savignyi. The same dominance of C. bicolor over C. savignyi occurred in laboratory experiments. These results suggest that the dominant species drives the subordinate one out of the high quality microhabitats, and that the subordinate species is forced to survive in the less lucrative habitats. In conclusion, coexistence seems to be maintained by the asymmetric competitive relationship between the two species and the fact that the subordinate species has the ability to endure in the less favourable microhabitat.

“…Many studies of ants have highlighted the importance of both intraspecific and interspecific competition in structuring communities (Cerdá et al 1998;Eldridge and Traniello 1981;Fox et al 1985;Holway 1999;Human and Gordon 1999;Passera et al 1996;Perfecto 1994;Punttila et al 1994;Savolainen 1990;Yamaguchi 1992). Competitive ability is important because the resource requirements of many ant species overlap substantially (Pisarski and Vepsä lä inen 1989), not just between closely-related species but also between distantly-related species (Mabelis 1984).…”

The role of competitive dominance in the invasive ability of the Argentine ant (Linepithema humile)

To assess the importance of competition in the advance of invasive species, bait stations have been used to determine the dominance hierarchy of a community of native ants in Doñ ana National Park, southern Spain, and the status of the introduced species Linepithema humile (Argentine ant). Some native species, e.g. Cataglyphis floricola or Camponotus pilicornis, seem to be subordinate, i.e. occupy a low position in the competitive hierarchy; some are dominant (e.g. Pheidole pallidula), and others (e.g. Aphaenogaster senilis) occupy an intermediate position in the hierarchy. The Argentine ant is a competitively dominant species, because of its aggressive behavior and relative abundance. Irrespective of their position in the dominance hierarchy, L. humile and some native species adopt what games theory terms ''the bourgeois strategy'' during agonistic encounters with other species. Lone workers tend to be submissive in encounters whereas workers in the presence of other colony members are aggressive. L. humile was the only species which aggressively displaced large numbers of ants of other species from the bait. L. humile also expanded its range in the course of the experiment, displacing native species from parts of the study area.
