Range Of Variation

Xanthosia pilosa Rudge is a common shrub found ineastern Australia. The species complex displays a wide range of variation inleaf and inflorescence morphology which has resulted in the application ofnumerous species names and its informal division into numerous variants in New South Wales. As part of a revision of the genus, the history of the speciescomplex is reviewed and the morphology of the numerous variants, examined bothin the field and herbarium, is discussed.Xanthosia pilosa sens. lat. is here divided into fourspecies: two new species (X. scopulicola J.M.Hart & Henwood and X. stellataJ.M.Hart & Henwood) are described and illustrated, a substitute name(X. ternifolia J.M.Hart & Henwood) is providedfor the illegitimate X. tasmanica Gand., andX. pilosa s.s., which remains a polymorphic species inwhich further segregation of variants is not recommended. A key toXanthosia species in eastern Australia is provided.

Original Concept

Digitate-leaved specimens of the genus Glycine from across southern Australia that have been determined as G. clandestina J.C.Wendl. encompass a wide range of morphological variation. Re-evaluation of this material has resulted in the conclusion that three species should be recognised. The original concept of G. clandestina (digitate-leaved plants with long, c. nine-seeded pods) can be applied only to plants from Queensland, New South Wales, Victoria and Tasmania. Two new species, G. peratosa B.E.Pfeil & Tindale and G. rubiginosa Tindale & B.E.Pfeil, are described from Western Australia and South Australia, respectively. Variation in G. clandestina s.s. is discussed in relation to contact zones with three other closely related species.

Summary Ficophagus from collecting trips in eastern Australia, made over 15 years, are summarised and show that species of the genus occurred widely in sycones of Ficus, subgenus Urostigma, section Malvanthera. Two new species (based on morphological differences and molecular sequencing) are described: Ficophagus elizabethae sp. n. from Ficus macrophylla, F. rubiginosa and F. obliqua, and Ficophagus richardi sp. n. from Ficus obliqua; and a morphospecies, Ficophagus Morphospecies malandicus from Ficus obliqua. Ficophagus elizabethae sp. n. is characterised by having the excretory pore (EP) opening from the level of the junction of the conus and shaft of the stylet to that of the knobs, a relatively long procorpus (1.0-2.5 times length of stylet), female tail with an obliquely truncate tail with a hyaline area and a finely to broadly rounded tip which may be mucronate; post-vulval uterine sac (PUS) ca one vulval body diam. (VBD) in length; rose-thorn-shaped spicule with distinct rostrum and prominent condylus; and genital papillae arranged as largest pair adcloacal, second pair posterior to mid-tail length, and third small pair near tail tip; and was collected from Sydney in New South Wales, to Bundaberg in Queensland (QLD). Ficophagus richardi sp. n. is characterised by having the EP opening at the level of the junction of the stylet shaft and conus, a labial cap which is raised around the opening for the stylet; procorpus 0.8-1.7 times length of the stylet, PUS <1 VBD in length, long uterus, and female tail with a V-shaped hyaline area at the bluntly rounded tip; rose-thorn-shaped spicule with a small rostrum and prominent condylus, three pairs genital papillae, first and largest on anterior cloacal lip, second at 70% of tail length measured from cloacal aperture, and third near tip, and was collected from Ban Ban Springs in the south to the Bundaberg region in the mid-north of QLD. In addition, in the absence of pertinent molecular sequences, a morphospecies is described. Ficophagus Morphospecies malandicus is characterised by having the EP opening anterior to the junction of the stylet conus and shaft, procorpus 0.9-2 times length of stylet, a short PUS usually <1 VBD long, short uterus, rose-thorn-shaped spicule with a raised condylus and prominent rostrum, and three pairs of subventral papillae on the tail (one adcloacal, one posterior to mid-tail and one near tail tip); and was collected from the Atherton Tableland, QLD. A table comparing morphological characteristics is provided to help with identification of Ficophagus nematodes from figs of the section Malvanthera in eastern Australia.

Occurrence Records

Concepts of the distribution of the greater broad-nose bat (Scoteanax rueppellii) have changed significantly as occurrence records have accumulated over the years. Early accounts of the species' distribution suggested that it was restricted to the heavily timbered areas of eastern Australia, and occurred over a wide range of altitudes. However, recent summaries of the distribution of the species differ significantly from these early accounts. To reconcile these discrepancies, I collated records from museum collections and wildlife databases. These data clearly indicate that stated altitudinal limits for the species are not correct. The currently known southern limit of the species is near Eden, New South Wales (NSW). The distribution of the species was modelled using the DOMAIN climate matching algorithm. The model indicates that S. rueppellii may occur in East Gippsland, Victoria, suggests its likely occurrence in inland Queensland and northern NSW, but a low likelihood of occurrence in inland southern NSW. However, the data show strong spatial and temporal biases that restrict the confidence that may be placed in the model. It is argued that species distributions must be regarded as open and evolving hypotheses.

Two new species of Achilini from eastern Australia are described and keys to the genera of Achilini in Australia, and species of the genus Anabunda, are provided. In addition, the type species of Anabunda is redescribed and the recorded distribution extended. The new species are Anabunda murrayfletcheri sp. nov. from Queensland, and A. minuta sp. nov. from New South Wales and Queensland. Both represent short-range endemic species, possibly under threat because of rapid urbanisation within their ranges. Biogeography and plant associations are discussed briefly.

Test Result

To further investigate the non-target impact of baiting using sodium monofluoroacetate (compound 1080) to control wild dogs, a population of radio-collared spotted-tailed quolls was subject to an experimental aerial baiting exercise. The trial was conducted at a site on the New England Tablelands, New South Wales, without a recent history of that practice. Sixteen quolls were trapped and radio-collared before baiting. Fresh meat baits were delivered from a helicopter at a rate of 10–40 baits km–1. In addition to 1080 (4.2 mg), each bait contained the bait marker rhodamine B (50 mg), which becomes incorporated into growing hair if an animal survives bait consumption. Two quoll mortalities were recorded following aerial baiting. Both quolls died 3–5 weeks after baiting when baits, on average, retained little 1080. None of the carcasses contained traces of 1080, but the test result is less reliable for the quoll that was found 19 days after its death although tissue was well preserved because of the cool weather. Nevertheless, given that this animal died 34 days after bait delivery, it appears likely that none of the radio-collared quolls succumbed to baiting. In contrast, vibrissae samples collected from 19 quolls captured after the baiting showed that 68% had eaten baits and survived. Furthermore, multiple bait takes were common, with up to six baits consumed by one female. The results demonstrate that most, if not all, quolls survived the baiting trial, including those that consumed dog baits. Hence bait consumption figures per se are not indicative of mortality rates attributable to poisoning.

Response To Temperature

E. nitens is a minor species of south-eastern Australia, having the growth potential for afforestation purposes. Variation was studied in seedlings raised under a wide range of temperature regimes with seed from six representative provenances. The results suggest that the species can be readily divided into three broad groupings, the two northern outlier occurrences of Ebor and Barrington, those in southern New South Wales, and the most southerly occurrences in Victoria. Leaf shape was found to be the best discriminatory character as it was independent of temperature. The provenances could also be distinguished on the basis of leaf area, but only when plants were raised under uniform temperature conditions.

History Of

Australian beachworms, recognized by specialists as one species Onuphis teres (Ehlers 1868), and by fishermen as a number of forms, were studied to determine whether more than one species was involved. Monthly sampling at a study site (Narrabeen, New South Wales) and collections from other localities were undertaken to study the morphology of beachworms, electrophoretic mobility of glucosephosphate isomerase and aspects of their life history. Three forms of beachworms-slimy, stumpy and kingworm-occur at the study site. Stumpies were found to be young kingworms, while slimy represents a separate species. The two species belong to Americonuphis Orensanz, 1974; the name is preoccupied and is replaced with Australonuphis. The holotype of A. teres is a kingworm and the closely related slimy is described as A. Parateres, sp. nov. Four other forms of beachworms were collected from northern New South Wales and Queensland: stripey, giant, wiry and white-headed wiry. These forms are referred to Onuphis. Stripey and giant are morphologically distinct and are described as O. taeniata, sp. nov., and O. gygis, sp. nov., respectively. Wiry and white-headed wiry belong to a polymorphic species described as O, mariahirsuta, sp. nov.

Shoot Blight

AbstractA young provenance/progeny trial of spotted gums, which are major hardwood plantation species in subtropical eastern Australia, was studied for growth, form, and damage from Quambalaria shoot blight. The trial contained a wide range of genotypes, mainly of Corymbia citriodora subsp. variegata, with between one and 21 families per provenance. Genetic parameters were calculated from 23 provenances with four or more families. Provenances superior for growth included four well-represented C. citriodora subsp. variegata provenances, all from south-east Queensland, which also had a high proportion of superior families. Overall, Queensland provenances had significantly higher mean diameter and height than those from New South Wales (NSW), although there were several superior NSW families. Provenances superior for growth also displayed good straightness and relatively fine branching. Relatively low Quambalaria shoot blight damage was recorded for four Queensland provenances and one coastal NSW provenance, which all had high proportions of families with low damage. Provenances that were putative intergrades between C. citriodora subsp. variegata and C. maculata tended to have high damage levels. However, some mediocre provenances contained superior families potentially useful for breeding. Regressions of Quambalaria damage index (QDI) on latitude, and mean height growth on QDI, were highly significant and moderately strong (0.51 and 0.58, respectively), indicating increasing damage in more southern material, and a retarding effect (although not striking) of damage on growth. Individual heritability estimates were low (zero to 0.14) for growth and form, and moderate for QDI (0.31). The genetic correlations for QDI with growth traits were strong and negative (-0.77 and -0.88), supporting a strategy of selecting vigorous trees for breeding programs from provenances and families superior for these traits.

Species Specific

Deep-water sharks have low biological productivity and are vulnerable to exploitation with species-specific regional life history required to enable effective management. The present study describes the life history of two squalids collected from Australia: (1) the piked spurdog (Squalus megalops) from the tropical Great Barrier Reef; and (2) the Philippine spurdog (S. montalbani) from New South Wales. Maximum observed ages for males and females were 18 and 25 years for S. megalops and 28 and 27 years for S. montalbani. Multiple growth models were all well supported and indicated very slow growth rates for both species. The tropical S. megalops population was smaller and older at maturity than previously reported temperate populations. Males were mature at 352-mm stretched total length (LST) and 12.6 years, whereas females were mature at 422mm LST and 19.1 years. Squalus montalbani males were mature at 700mm LST and 21.8 years, whereas females were mature at 800mm LST and 26 years. Fecundity was lower for S. megalops than S. montalbani with two to three compared with nine to 16 embryos. Both species have a conservative life history, although in the event of overfishing the longer-lived, later-maturing and deeper-dwelling S. montalbani is likely to take longer to recover than S. megalops.
