Abstract:

'The habitat and microhabitat preferences, and times of activity, of the skinks Egernia modesta and E. whitii were examined in southern Queensland where they coexist in a narrow zone. The above parameters were compared between locally sympatric and allopatric populations, in an attempt to determine whether there was evidence of niche separation in sympatry. E. modesta preferred open habitats with little canopy cover and high grass cover, adjacent to rocky retreats. E. whitii preferred rocky areas with well developed canopy and shrub layers. Both species were active throughout the day, although E. modesta was active later than E. whitii. No evidence was found of competition restricting habitat preferences where the two species coexisted. It is suggested that human disturbance has had some influence on current distributions of these species.

Abstract:

Allozyme electrophoresis was used to assess the taxonomic significance of colour pattern variation within and between populations of the Egernia whitii species group from 41 locations in south-eastern Australia. Analysis of the products of 39 presumed loci revealed that a minimum of three species are present in southern New South Wales among populations previously referred to Egernia whitii. Fixed allelic differences were maintained where pairs of species were sympatric. One of these three species is wide-ranging and is the one to which the name E. whitii is properly applied. The other two are more restricted ecologically and geographically and are described here as new. The three species are genetically and morphologically distinct from the other three eastern Australian members of the species group, E.�margaretae, E. modesta, and E. multiscutata. Genetic data and a review of the morphological evidence provide no support for the recognition of subspecies within either E. whitii (sensu stricto) or E. multiscutata.

Abstract:

The reproductive cycles of two closely related skinks, Egernia modesta and E, whitii, in southern Queensland are described and compared in sympatric populations. They are very similar, both species produce 1-5 live young about 40 mm long in January-early February. Lizards mature at the end of their second year and litter size is positively related to female body length. Adults grow to 110 mm and appear to live at least 4 years. Two non-hybridising colour morphs of E. whitii were present in the study area and did not associate at random. Possible mechanisms explaining the evolution of these three closely related forms, which can coexist in similar habitats, are discussed.

Abstract:

The viviparous skink Egernia whitii is dimorphic for dorsal colour pattern. Both patterned and plain morphs coexist throughout the species' range. Adults live in family groups beneath exfoliating granite rocks. The closely related E. modesta also coexists in similar habitats in the northern part of the range of E. whitii. The plain E. whitii morph is intermediate in colour pattern between patterned E. whitii and E. modesta. Three populations of E. whitii and two populations of E. modesta were examined electrophoretically to assess the status of the plain morph of E. whitii. There were no fixed differences between the two morphs of E. whitii at any of the 55 loci examined, and loci polymorphic in both rnorphs of E. whitii showed no evidence of linkage disequilibria. Although heterozygosity values (H=0.017�0.002) and the level of polymorphism (P 0.95=0.015) were low, there were highly significant allele frequency differences between sympatric samples of the two morphs of E. whitii. This indicated that the two morphs were conspecific, yet they were not interbreeding at random. The established frequency of gene exchange between the two colour morphs in the three populations sampled varied from 3.6 to 6 individuals per generation. Reproductive data confirmed that both colour morphs of E. whitii produced young of the same dorsal colour pattern as their own in much greater frequency than random. However, females of both colours can and do breed with males of the other colour in very low frequency. Analysis of the lateral colour pattern of the two E. whitii morphs and E. modesta suggests that the colour patterns of the two E. whitii morphs are very similar, yet differ slightly from the colour pattern of E. modesta in the region of geographic overlap of these species. These results suggest that behavioural or microhabit differences between the two morphs may be involved in mate recognition.

Abstract:

The life history and reproductive ecology of White’s skink, Egernia whitii, was examined in a population in the Australian Capital Territory using both field and genetic studies. Colour pattern polymorphism was evident within the population, with both patterned and plain-back morphs present. Lizards typically took 3 years to reach sexual maturity, with the size at maturity being ~75 mm snout–vent length (SVL) in both sexes. There was an even overall adult sex ratio, although a slight female-bias was evident in plain-back individuals. Sexual dimorphism was evident, with males having longer and wider heads, and females having larger body size. Females generally bred annually, with mating occurring in September–October and parturition in late January–February, although the litter was produced over several days (2–10 days, mean 4 days). Litter size ranged from one to four (mean of 2.5). There was a significant relationship between maternal SVL and both litter size and relative clutch mass, but these trends were not consistent between colour morphs. An inverse relationship between litter size and offspring size (SVL and mass) was found. Comparison of the results with previous investigations of E. whitii indicates substantial geographic variation in life-history traits that is presumably associated with latitudinal variation in climatic conditions.

Abstract:

Individual differences in behaviour are ubiquitous in nature. Despite the likely role of selection in maintaining these differences, there are few demonstrations of their fitness consequences in wild populations and, consequently, the mechanisms that link behavioural variation to variation in fitness are poorly understood. Specifically, the consequences of consistent individual differences in behaviour for the evolution of social and mating strategies have rarely been considered. We examined the functional links between variation in female aggression and her social and mating strategies in a wild population of the social lizard Egernia whitii . We show that female Egernia exhibit temporally consistent aggressive phenotypes, which are unrelated to body size, territory size or social density. A female's aggressive phenotype, however, has strong links to her mode of paternity acquisition (within- versus extra-pair paternity), with more aggressive females having more offspring sired by extra-pair males than less aggressive females. We discuss the potential mechanisms by which female aggression could underpin mating strategies, such as the pursuit/acceptance of extra-pair copulations. We propose that a deeper understanding of the evolution and maintenance of social and mating systems may result from an explicit focus on individual-level female behavioural phenotypes and their relationship with key reproductive strategies.

Abstract:

Montane (cold-climate) habitats may impose severe thermal constraints on habitat use by ectotherms, favouring strong interspecific convergence in the attributes of suitable shelter-sites. We studied shelter-site use by five species of viviparous scincid lizards in Kanagra Boyd National Park, a montane (1200 m above sea level) forested region 160 km west of Sydney. We scored 21 attributes of 93 shelter-sites (13–20 per species), and the same attributes at unoccupied 'control' sites. These attributes included macrohabitat (e.g. canopy openness, substrate type, distance to waterbodies and logs) as well as shelter-site characteristics (e.g. type of cover-item, size of crevice). Hemispherical-lens photographs and gap-analysis software yielded estimates of solar radiation at each site, and data-loggers recorded temperature profiles in each occupied retreat-site. Principal Components Analysis of the data set identified eight axes of variation. Significant interspecific differences were evident on four of these axes, but with substantial overlap reflecting the broad syntopy of the taxa, plus similarities in characteristics of occupied retreat-sites (e.g. most lizard species utilised sun-exposed shelter-sites with logs nearby). Egernia species (cunninghami, saxatilis, whitii) typically used more open habitats than did Eulamprus (heatwolei, tympanum). Egernia cunninghami used very large crevices, whereas Eulamprus tympanum occupied heavily wooded macrohabitats. At this cold-climate site, interspecific similarities in the characteristics of utilised retreat-sites generated substantial overlap among species in the kinds of sites used, potentially intensifying interference competition among these taxa.
