Abstract:

Details of the size, structure and occurrence of Carnponotus intrepidus nests and the size, composition and source of the mound cover on Iridomyrmex purpureus nests are reported from several areas of eastern New South Wales. Both species are common, and construct large mounds of mixed topsoil and subsoil with surface covers, which appear to protect the mound from rainsplash erosion. Camponotus thatches the mound with charcoal, leaves and twigs; Iridomyrmex covers the mound in granules of inorganic or organic material that are sufficiently large to absorb most raindrop impact energy. This material is collected from the surface and carried 10-15 m to the nest. Rainsplash erosion protection is probably a factor contributing to nest longevity, which may be as much as 100 years for Iridomyrmex. It is concluded that, despite the impressive size of the nests and the selective use of materials, neither species is very significant in terms of soil mixing when compared with the smaller, more common ant Aphaenogaster longiceps.

Abstract:

The ant communities of nine sites near Lawn Hill (540 mm mean annual rainfall) in semi-arid north-western Queensland are documented, and compared with the known faunas of arid, semi-arid and seasonally arid sites elsewhere in Australia. The sites were surveyed primarily by pitfall trapping, during April (end of wet season) 1991, September (late dry season) 1991, and February (mid-wet season) 1992. A total of 111 ant species was recorded, with the most common being Iridomyrmex spp. and Rhytidoponera rufithorax. The richest genera were Melophorus (26 species), Monomorium (17), Iridomyrmex (16) and Camponotus (10) and Pheidole (10). The maj or functional groups were Dominant Dolichoderinae (Iridomyrmex spp.; 14% of the total number of species, 47% of the total number of ants in traps), Hot-climate specialists (mostly Melophorus spp.; 39%, 22%) and Generalised Myrmicinae (mostly Monomorium and Pheidole spp.; 20%, 11%). Multivariate analysis indicated that site differences in species composition were related primarily to landform, geology and soil type. Comparisons with other ant faunas show the Lawn Hill fauna to have closer affinities with those of the central arid zone than with those of high rainfall areas of the seasonal tropics. The arid-zone characteristics of the Lawn Hill fauna include a high proportion (38%) of Eyrean species, a high mean number of species per genus (6.5), and a very high combined representation of Iridomyrmex, Melophorus and Camponotus (45% of the total number of species, 69% of the total number of ants in traps).

Abstract:

Summary. Pitfall traps were used to monitor the seasonal activity of ants in 2 citrus orchards in the Murrumbidgee Irrigation Area of south-western New South Wales for 22–24 months (November 1992–August/October 1994). Twenty-four species were recorded (22 species at Yanco and 18 species at Cudgel), with Iridomyrmex rufoniger group species being numerically dominant at both sites (63 and 59% of total captures at Yanco and Cudgel respectively). Meat ants, Iridomyrmex purpureus (F.Smith), were a significant (9%) component of trap captures at Yanco where regular soil cultivation was practised, but were less common (<1% of captures) at Cudgel. Sample species richness was generally greater at the Yanco site (mean 9.3 species per trapping interval compared with 6.6 at Cudgel). Total ant captures and sample species richness showed a positive correlation with mean daily temperatures over trapping intervals. Variations in seasonal activity were shown by the numerically dominant species, with 2 distinct patterns being evident. Whilst all taxa were less active during winter, some species [I. rufoniger group sp. 2, Pheidole sp., Rhytidoponera metallica (F.Smith)] continued to forage, albeit at reduced levels. Other species of Iridomyrmex including I. rufoniger group sp. 1 and I. purpureus ceased foraging almost entirely during June–September. Iridomyrmex species are known to interfere with the biological control of honeydew-producing insects in citrus orchards, and our results indicate that ant control programs in southern New South Wales should be initiated in late August–early September to achieve optimal results.

Full text

Abstract:

Adjacent heath and woodland sites at Wilsons Promontory in Victoria support at least 50 species of ants, with the most abundant being Rhytidoponera victoriae, Iridomyrmex spp. (nitidiceps group), Notoncus hickmani, Aphaenogaster longiceps, Camponotus ?intrepidus and Plagiolepis sp. Total numbers of individuals and species in the woodland were twice that in the heath; this was probably caused by the greater structural complexity of vegetation there, which increased the availability of nesting and foraging sites, the level of insolation of the ground, and possibly also food supply. Total ant activity followed seasonal cycles which correlated with changes in temperature and probably also food supply, and, within these constraints, was regulated by prevailing weather conditions. Individual species displayed distinctive foraging schedules which possibly play an important role in species coexistence. Community organization is analysed according to a scheme derived from studies of ants in arid Australia, where taxa are classified according to their physical requirements and their relationships with dominant species. Although the major species in the present study were separated by differences in body size, food type, and time of foraging, interspecific competition appears to be less important than it is in arid regions. At both sites, opportunistic species (Rhytidoponera) predominated, cryptic species (those associated with soil and litter, such as Plagiolepis sp. and Solenopsis sp.) were abundant, and Iridomyrmex appeared to have a relatively weak influence on the abundance of other ants. This contrasts with the situation in arid regions, where species of Iridomyrmex are extremely important, and opportunistic and cryptic species are often rare or absent.

Abstract:

We describe the diversity, composition, functional group organisation and biogeography of ants in Purnululu National Park (128°19′E, 17°19′S) in Western Australia’s Kimberley region, located at a semi-arid/tropical zone boundary. Pitfall trapping collected a representative sample of ants from three main habitats within the park: spinifex, sandplain and gorges. In total, 154 species from 25 genera were collected. The richest genera were Melophorus, Iridomyrmex and Monomorium. Iridomyrmex was the most abundant genus, accounting for 80% of all individuals recorded in traps. Functional group composition was dominated by Dominant Dolichoderinae (41% of individuals collected) and Hot Climate Specialists (26%). Biogeographical composition was typical of semi-arid zone assemblages located on the overlap between Eyrean and Torresian zones: 50% of the species recorded represented Eyrean taxa, followed by 33% with Torresian affinities, and 10% Widespread. Differences in ant species richness, abundance and assemblage composition between the three habitat types were attributed to a combination of variation in vegetation structure and microhabitat composition. This paper provides baseline data on local ant communities in the semi-arid Kimberley, enabling a greater understanding of the conservation value of reserves within the Kimberley, one of Australia’s least studied bioregions.

Full text

Abstract:

Ants were collected from the canopies of mallee eucalypts at Wyperfeld National Park in north-western Victoria by beating foliage on ten occasions from September 1979 to December 1980. The study was conducted at two adjacent sites: one that had been burnt by a wildfire during early 1977, and the other long unburnt. Both sites contained a mixture of three mallee eucalypt species: Eucalyptus dumosa, E. foecunda and E. incrassata. In contrast to the canopies of other eucalypt formations elsewhere in southern Australia, abundance and diversity of ants were very high. Ants represented 43-69% of all invertebrates, and a total of 44 ant species from 19 genera was collected. Iridomyrmex and Camponotus respectively contributed 10 and 11 species, and the most abundant ants were species of Iridomyrmex, Monomorium and Crematogaster. Ant composition was broadily similar at the two sites, and on different canopy species, although significant differences in abundance were apparent for some individual ant species. Except for tree-nesting Podomyrma adelaidae and Myrmecorhynchus sp. nr emeryi, the fauna was dominated by ground-nesting species, most of which appeared to forage on vegetation opportunistically. The unusually high abundance and diversity of the canopy ant fauna are attributed to the close proximity of the mallee canopy to the ground, coupled with an exceptionally rich ground ant fauna.

Abstract:

Understanding the dispersal of weed species is important for the development of effective control strategies. In this study, a series of experiments was conducted to clarify the role that meat ants (Iridomyrmex spadius) play in dispersing bellyache bush (Jatropha gossypiifolia), an exotic shrub currently invading the rangelands of northern Australia. The nutrient composition of food [lipids (fatty acids), fat and soluble carbohydrates] provided by bellyache bush seed components [caruncle, exotegmen and seed (without caruncle and exotegmen)] was identified. Seed components were rich in lipids, particularly palmitic, oleic, stearic, linoleic and eicosenic acids. Oleic and palmitic were most abundant in the caruncle (30% each), linoleic in the seed (61%) and palmitic in the exotegmen (36%). Over all seed components, fat concentration was relatively high (6.3%) compared with soluble carbohydrates (2.3%). The impact of feeding was then determined by comparing germination and viability of intact, non-carunculate (caruncle manually removed) and ant-discarded bellyache bush seeds. Feeding by meat ants significantly increased seed germinability, whilst having no adverse affects on viability. The quantity of seeds dispersed and the seasonal pattern of dispersal was recorded by collecting seed from the middens of randomly selected meat ant nests on a monthly basis. On average, 12 330 ± 603 seeds were retrieved from the middens of individual meat ant nests over 12 months, with highest numbers recorded between February and June (>1200 seeds/ant nest). The effect of this dispersal was determined through comparisons of plant densities within core infestations of bellyache bush, meat ant nest middens and pastures located directly adjacent to core infestations and that were being invaded primarily through localised ballistic dispersal. The density of bellyache bush plants growing from the seed reserves within middens averaged 79 plants/m2, just 18% less than that within core infestations. Seedling survival (1 year) and growth within core infestation and meat ant sites was also quantified. The middens of meat ant nests provided an environment conducive to higher seedling survival and faster growth rates than occurred within core infestations. Mutualistic interaction between bellyache bush and meat ants is likely to build local ‘infestation pressure’ that may be conducive to range extension in years of exceptionally wet seasons. Management of seed dispersal by meat ants may reduce that risk.

Full text

Abstract:

In polydomous ants, individuals belonging to a single colony occupy a variable number of neighbouring nests. Polydomy is frequently associated with polygyny and species are often both facultatively polydomous and facultatively polygynous. In this study we test the generality of this association by investigating the genetic and spatial structure of polydomous colonies of Iridomyrmex purpureus in New South Wales, Australia. Genetic analysis of 15 colonies revealed high relatedness within all but one of the colonies, indicating that the workers are mostly produced by one, singly inseminated queen. Polydomy in this population therefore is not associated with polygyny. Intriguingly, our behavioural data suggests that the colony with low within-colony relatedness had been recently formed by colony fusion. While genotypes were not distributed homogenously throughout this newly formed colony, there was an obvious exchange of genotypes between the nests of the two former colonies. During 2 years of field observations in which we observed 140 colonies comprising over 1000 nests, we observed colony fusion only twice. We discuss these findings in relation to the current theories on the relationship between polydomy and polygyny.

Full text

Abstract:

The biogeography and structure of ant communities were examined over a 12-month period at a dry open eucalypt forest in south-eastern Queensland. Three sites were monitored, each with a distinct long-term burning history: burned annually since 1952, burned periodically since 1973, and unburned since 1946. A total of 89 species from 42 genera was recorded over all trapping periods, with the richest genera being Iridomyrmex, Camponotus and Pheidole, each with eight species. Site species richness was 74, 63 and 43, respectively, at the annually burned, periodically burned and the unburned site. We compared the ant community in this forest with those at other forested sites in eastern Australia. Overall, the south-eastern Queensland community was located on the overlap between the Bassian and Torresian zones (not dominated by either element), while the functional-group composition resembled those of both tropical savannas and cool-temperate woodlands. There were readily discernible differences between sites in terms of biogeographical and functional-group composition; and between the unburned site and both burned sites in terms of abundance and species richness. The relative abundance of Iridomyrmex spp. increased with burning frequency while the relative abundance of Bassian species decreased with burning frequency. Species richness and abundance at the burned sites were similar, but substantially higher than at the unburned site. The community characteristics of the three sites were readily distinguishable, indicating that ant communities may play a valuable role in detecting ecological changes in forested landscapes in south- eastern Queensland.

Full text

Abstract:

Ants use multiple cues for navigating to a food source or nest location. Directional information is derived from pheromone trails or visual landmarks or celestial objects. Some ants use the celestial compass information along with an ‘odometer’ to determine the shortest distance home, a strategy known as path integration. Some trail-following ants utilise visual landmark information whereas few of the solitary-foraging ants rely on both path integration and visual landmark information. However, it is unknown to what degree trail-following ants use path integration and we investigated this in a trunk-trail-following ant, Iridomyrmex purpureus. Trunk-trail ants connect their nests to food sites with pheromone trails that contain long-lasting orientation information. We determined the use of visual landmarks and the ability to path integrate in a trunk-trail forming ant. We found that experienced animals switch to relying on visual landmark information, and naïve individuals rely on odour trails. Ants displaced to unfamiliar locations relied on path integration, but, surprisingly, they did not travel the entire homebound distance. We found that as the homebound distance increased, the distance ants travelled relying on the path integrator reduced.

Abstract:

The conifer species-group of the ant genus Iridomyrmex is defined and revised at the species level. The species I. conifer Forel, I. setoconus, sp. nov. and I. turbineus, sp. nov. are placed in the group, which is limited to south-western Australia. A key to species is provided and distributions are summarised. These ants show unusual nesting habits in that thatched mounds are used during the cooler winter months and subterranean nests are constructed during the hot summer months. This habit is not known to occur in any other ant. These ants are opportunistic feeders utilising a variety of food sources and will readily relocate nest sites in response to changing resources.

Abstract:

SynopsisThe structure and diversity of fern spores, based on SEM studies, are assessed in relation to general evolutionary trends and systematics. A review of spores of myrmecophytic ferns includes SEM figures of eight species and the ant Iridomyrmex cordataus. The diversity, especially in Lecanopteris spores, is correlated with other characters indicating systematic differences of the species. Convergence is shown in the echinate spores of the neotropical Solanopteris and those of the paleotropical Drynaria and Selliguea. Evidence for adaptation of spore structure to transport by ants is especially clear in the development of filamentous elements, unique among pteridophytes, in Lecanopteris mirabilis. These demonstrate an unusual labile nature of the wall, and provide insight into the functional role of intricate surface formation of spores.

Abstract:

Abstract Many invasive invertebrates belong to unresolved species complexes, and have a history of misidentification and inappropriate management. Here we detail confusion surrounding the taxonomy and identification of two dolichoderine ant species, Iridomyrmex anceps Roger and Ochetellus glaber Mayr, which are commonly cited in the literature as having been spread widely by human commerce. We provide morphometric data and images strongly suggesting that these two “species” are instead complexes of species that are likely native to many regions where they are purportedly introduced. We take particular interest in the status of species referred to as I. anceps and O. glaber in China, as this is the most northerly distribution of both genera. We conclude by suggesting that many identifications of both species are likely to be unreliable, and we recommend against any management action aimed at controlling these species under the assumption that they are exotic.

Abstract:

AbstractA new species of Technomyrmex (T. caritatis sp. n.) is described based on workers and larvae from Dominican amber (Oligocene to Lower Miocene). These are preserved with eggs and pupae of the same species and with five other insects in one amber piece found in the Palo Quemado Mine, near Santiago and in two separate amber pieces collected in Carlos Diaz Mine. Both mines are in Cordillera Septentrional. Iridomyrmex hispaniolae Wilson is redescribed and transferred to Technomyrmex. Most Technomyrmex species occur from Africa, east through southern Asia, to Australia. One species transported by human activity is known in the New World and there is only one extant native Neotropical species recorded from Panama. Technomyrmex likely represents a case of an Old World ant genus undergoing extinction in the New World. We discuss the affinities of this genus with the extant Dolichoderinae and the phylogeny of the subfamily.

Abstract:

Underground ant nests are typically made of soil and rubble mixed with dead plant bodies, ant secretions, and other organic substances. The clay content is high, and the natural clay materials show pozzolanic activity after calcination. In this study, the underground ant nest materials of Iridomyrmex anceps, which is a common ant in the Shanghai area, are calcined and ground, and the material properties of calcined ant nest clay powder (CANCP) are characterized from six aspects: chemical composition, particle morphology, specific gravity, specific surface area, particle size distribution and pozzolanic activity index. The pozzolanic activity of CANCP is evaluated by the strength contribution rate of pozzolanic activity, revealing that CANCP is beneficial to the strength of the mortar system from an early age. The influence of CANCP on the compressive strength of concrete is analyzed using three aspects, namely, content, curing age and calcination temperature, and it is found that the three aspects of CANCP have a strong influence on the compressive strength of concrete.

Abstract:

The sugary exudate appearing on bark lesions of Persea americana Miller and Persea indica plants after infection with Phytophthora citricola contained viable oospores and hyphal fragments in the field and in the greenhouse. This sugary exudate was a source of inoculum and dispersal of the pathogen within and between avocado plants. Spraying water onto lesions moved inoculum from the sugary exudate to wounds below. Water from sprinkler irrigation washed propagules into the soil around the plants. Viable propagules of Phytophthora citricola were identified in the feces of snails (Helix aspersa) that had fed on infected bark tissues. When these snails were moved to healthy plants, they made wounds on succulent tissue, and the infectious feces induced cankers. Ants (Iridomyrmex humilis) were attracted to the sugary exudate and also transmitted infectious propagules to wounds on avocado stems and to the soil. Control strategy for the avocado stem canker disease should consider control of vectors.
