Streszczenie:

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.

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).

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.

Streszczenie:

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.

Streszczenie:

The ants of the purpureus group of the dolichoderine genus Iridomyrmex are revised. The group is defined for the first time and divided into four complexes (bigi, purpureus, sanguineus, viridiaeneus). Three of the previously known taxa, I. purpureus purpureus (F. Smith), I. purpureus sanguineus Forel and I. purpureus viridiaeneus Viehmeyer, are redescribed and the last two are raised to full species, while I. detectus castrae Viehmeyer is synonymised under I. purpureus. Additionally, eight new species (I. bigi, I. galbanus, I. greensladei, I. lividus, I. reburrus, I. spadius, I. spodipilus, I. variscapus) are described. A key for the separation of workers is presented, and known biologies and distributions are summarised.

Streszczenie:

On sait que la reine des insectes sociaux joue un role capital dans la reproduction. Son role dans l'attraction des ouvrieres et la realisation de la cour royale est moins connu. En choisissant comme modele la fourmi d'argentine linepithema humile nous avons etudie les conditions qui regissent l'agregation des ouvrieres autour des reines. Nous avons demontre que les ouvrieres sont beaucoup plus attirees par leurs propres reines que par des reines d'origine geographique eloignee. Des differences genetiques et/ou environnementales entre les complexes pheromonaux emis dans les deux situations pourraient etre a la base de cette discrimination. Des experiences menees sur des cadavres royaux et sur des reines vivantes ont permis de cerner les facteurs responsables de l'attraction royale. Elles mettent en evidence le role de substances chimiques, a court rayon d'action, emises par la reine et percues par les ouvrieres grace a une chimioreception de contact. L'hypothese que des hydrocarbures cuticulaires puissent etre a l'origine de cette attraction a ete envisagee. Nous avons donc essaye d'eliminer les substances impliquees dans cette attraction en lavant les cadavres de reines au moyen de solvants organiques. Ceci a entraine une forte reduction du pouvoir attractif royal, confirmant l'existence d'une substance chimique cuticulaire. D'autres experiences ont mis en evidence un lien etroit entre l'attraction royale, l'age de la reine et son statut physiologique. L'attractivite faible a l'emergence de la reine vierge, le reste encore au moment de la fecondation et de la perte des ailes. C'est au declenchement de l'ovogenese, c'est-a-dire au demarrage de l'activite de ponte que cette attractivite augmente de facon significative

The main objective of this study was to examine the abundance and diversity of ants in suburban sites following vegetation removal or modification for development. This research examines the capacity of suburban sites to support ant diversity, which is dependent on the site characteristics and their surrounding environment. The study focused on 29 suburban garden and 3 suburban reserve sites on the Gold Coast, Queensland, Australia. This region, through continuing land development, undergoes ongoing habitat disturbance and modification. Ground-dwelling ants were collected by pitfall trapping in study sites over three summers between 1997 and 1999. In total, 28,512 ants from 60 species in 31 genera were collected. Garden sites that maintain vegetation structural diversity were found to be most similar to reserve sites in terms of ant community composition. These sites were highest in ant richness and diversity and contained particularly high proportions of specialized ant species. Sites in close proximity to remnants of native vegetation contained higher species diversity and a greater proportion of specialized ant species. The introduced tramp ant, Pheidole megacephala was found in 28 of the 32 sites and was found to significantly reduce ant species richness and diversity and displace the dominant ant Iridomyrmex sp. 1 in suburban environments. This ant poses a serious threat to the recovery of a diverse ant fauna to suburban environments. Ant community composition was shown to vary significantly among suburban sites. The ant functional groups commonly found in disturbed sites were abundant in open sites with little canopy cover in this study. Sites that provided vegetation structural diversity and areas of closed canopy supported similar functional groups to natural vegetation remnants. These results indicate that ant communities in suburban environments respond to disturbance in a similar manner to ant communities in tropical forests and rainforests. The dominance by functional groups and presence of specialized species may therefore be used as an indicator of disturbance and the restoration of suitable habitat in suburban sites. The presence of specialized species of ants in suburban garden sites and their clear preference for particular site characteristics indicate that these species utilize resources available in the suburban matrix. These results indicate that residential suburban sites are of value in the enhancement of ant diversity in fragmented landscapes and that they may provide supportive habitat to, and act as corridors between, vegetation fragments. In order to preserve biodiversity within suburban environments, landowners should be advised to retain as much existing vegetation within a site as possible. Clearing should be limited to that necessary to allow construction of dwellings and for safety. In addition, landowners should be encouraged to establish or maintain structurally diverse vegetation layers within sites in order to provide diverse microenvironments for fauna habitat.

Streszczenie:

The main focus of this thesis is the study of sensory systems in the context of changing body-size. In particular the study of ant sensory systems and how these are shaped by miniaturisation. The study of insect visual ecology and physiology is used as a basis to develop a framework for the study of ant antennal sensilla and chemosensation, to interpret anatomical variation from a functional and organ design perspective. This thesis reviews the anatomy and nomenclature of antennal sensilla through two case studies on an extremely large species Myrmecia pyriformis and a small species Temnothorax rugatulus. These two studies additionally quantify intraspecific variation and discuss the potential functional consequences of this variation for self-organising insect societies and task allocation. A large scale comparative study takes the tools developed in previous chapters to focus in on how chemosensilla vary in their numbers, size and distribution through the Fomicid phylogeny. The gross anatomy of the antenna and changes in shape from club to filiform antennae are described in detail. Anatomical data are analysed to identify scaling trends and potential adaptations driven by miniaturisation. Ecological and phylogenetic considerations are discussed wherever relevant. The wide ranging impacts of body size changes are reviewed, incorporated into the interpretation of results and used to propose promising avenues for future research. Finally, ant body size and some of the different methods used in the literature to measure size and size variability are critically analysed. The functional implications of body size variability within species are discussed using Iridomyrmex purpureus as an example. This thesis makes use of a variety of microscopy techniques. In addition to the methods sections of each chapter a dedicated methods chapter is included. This chapter reviews some of the techniques used in the main data chapters and in the additional publications produced over the course of this thesis.
