Native Strains

Rhizobia present in soils from western New South Wales and from the New England Tableland were subjected to a series of high temperature survival tests. Rhizobia present in air-dry soils survived temperatures higher than would be experienced under natural conditions. In moist soils the tolerance of medic rhizobia to high temperatures was much lower. Strains of Acacia, Lotus and Psoralea rhizobia from western New South Wales survived higher temperatures than strains from the New England Tableland, but the tolerance to high temperatures of medic rhizobia did not vary with source. This suggests an ecological adaptation of the three native strains not found in the introduced Medicago rhizobium.

Medicago Species

Tests of 84 cultures of root-nodule bacteria isolated from four species of clover growing in the Lismore district of New South Wales (three soil types, 18 localities) showed them to be generally effective in association with white and red clovers, but almost always parasitic on subterranean and crimson clovers. Successful seed inoculation with beneficial strains of rhizobia is, therefore, essential to the introduction of subterranean and crimson clovers in these soils. Field observations have also demonstrated the need to inoculate seed of Medicago species, cowpea, and vetch.

The diets and growth rates of rainbow trout in the Wollomombi and Guy Fawkes Rivers in northern New South Wales were examined. The growth rate of trout in the Wollomombi River was much higher than that of fish in the Guy Fawkes River. Spearman rank correlation coefficients indicated that stream type was more important than fish size in determining the composition of the diet of the trout. Benthic invertebrates formed the largest component of the diet in both streams: 66.0 and 63.0% of ash-free dry weight (AFDW) in the Wollomombi River and the Guy Fawkes River, respectively. Trout in the Wollomombi River consumed more nektonic prey (33.3% of AFDW) than fish in the Guy Fawkes River (3.7% of AFDW). In contrast, surface food (aquatic imagines and terrestrial insects) made up a much higher proportion of the diet of trout in the Guy Fawkes River (33.9% of AFDW) than in the Wollomombi River (0.6% of AFDW). Crayfish were a major component of the diet (in terms of AFDW) in both streams, their proportions increasing with fish size. The significance of crayfish in relation to fish growth is discussed.

Antechinus Stuartii

Previous work on bioclimatic mapping of species within the Antechinus stuartii–A. flavipes complex has been carried out, but this was before A. subtropicus was recognised and a complete taxonomic revision of the complex had been completed. This revised study of bioclimatic modelling of species within the A. stuartii–A. flavipes complex indicates substantial differences between the four species (A. stuartii, A. agilis, A. subtropicus and A. flavipes) in 35 climatic indices. A. stuartii is predicted to have a near-coastal distribution in northern and central New South Wales stretching as far south as Kioloa and as far north as south-eastern Queensland, avoiding the far coastal strip. A. agilis is predicted to have an extensive distribution in Victoria and southern New South Wales as far north as western Sydney; it is also predicted to occur in Tasmania, even though there is no evidence of it ever occurring there. A. flavipes is predicted to have an extensive inland and coastal distribution much larger than its recorded distribution. A. subtropicus is predicted to have a very narrow distribution in areas with high seasonal rainfall and high temperatures with low seasonality. All species are predicted to occur sympatrically, with A. stuartii and A. agilis predicted to have extensive overlap on the coast near Kioloa and to the immediate west and south-west of Sydney.
