New Host Records

The ectoparasites of northern quolls, Dasyurus hallucatus, are reported from 79 animals live-trapped at Kapalga Research Station, Kakadu National Park, during 1992–95. The ecto- and endoparasites are reported from 62 dead D. hallucatus during the same period; these were mostly road-kills collected from an 88-km section of the Arnhem Highway between Jabiru and the Northern Entry Station of Kakadu National Park. Tissues from 28 of the road-kills were examined histologically. Additionally, 214 scat samples were examined for ecto- and endoparasites. Seven species of ectoparasite, including two species of tick, a larval trombiculid mite, a louse and two (possibly three) species of flea, and 17 species of endoparasite including a trematode, a larval cestode, 13 species of nematode, a larval pentastome and a protozoan were recorded from D. hallucatus. Sarcocystis sp. was found in tissues but neither Toxoplasma gondii nor Trichinella pseudospiralis were detected in histological sections or tissue digests. Ticks, mites and nematodes were found in scats. The tick Haemaphysalis bancrofti, the flea Echidnophaga aranka and possibly E. ambulans, and the nematodes Mackerrastrongylus peramelis and Cylicospirura heydoni represent new host records for D. hallucatus. Although parasitism was common in D. hallucatus, few individuals harboured large burdens. Consequently, it appears unlikely that parasitism is a major factor contributing to the decline of northern quolls in this region.

Host Parasite

Seven new taxa in two families of metastrongyloid nematodes are described from the lungs of five host species belonging to the Dasyuridae, Phalangeridae and Macropodidae. Filaroides (Filaroides) athertonensis, sp. nov., (Filaroididae) is described from Thylogale stigmatica Gould in north Queensland. The following species of Marsupostrongylus Mackerras & Sandars, 1953, (Angiostrongylidae) are described as new: M. parallelus, sp. nov., from Satanellus hallucatus (Could) in the Northern Territory; M. pseudominesi, sp. nov., from Trichosurus vulpecula johnstonii (Ramsay) in north Queensland; M. vandiemeni, sp. nov., from macro pus rufogriseus rufogriseus (Desmarest) in Tasmania; and M. wallabiae, sp. nov., from Wallabia bicolor (Desmarest) and Macropus rufogriseus banksianus (Quoy & Gaimard) in New South Wales. To the formerly monotypic genus Filostrongylus Mackenas, 1955, (Angiostrongylidae) is added F. tridendriticus, sp. nov., described from Trichosurus vulpecula (Kerr) in Tasmania. The genus Cosmostrongylus (Angiostrongylidae) is described as new, with a single species C. conspectus, sp. nov., from Thylogale stigmatica Gould in north Queensland. Durikainema sp. (Muspiceoidea: Robertdollfusidae) is diagnosed in histological sections of the lungs of Phascolarctos cinereus (Goldfuss), Macropus agilis (Could) and M. giganteus Shaw. Keys to the genera of lung parasites and to all species of Filaroides, Marsupostrongylus and Filostrongylus known from Australian marsupials, new host and new geographic records of known taxa, and a host-parasite list of lung parasites of Australian marsupials, including those known only from histological sections of lung tissue, are provided.

New Host Records

A natural population of Deroceras laeve was examined regularly for the presence of Cosmocercoides dukae (Holl, 1928) Travassos, 1931. Transmission of C. dukae in D. laeve occurred in late spring and early summer before adult slugs from the previous year died in July. Transmission to juvenile slugs (hatched from eggs laid in spring) continued in late summer and fall. Histological sections of slugs exposed experimentally to larvae of C. dukae revealed that larvae penetrate slug tissues. Arion fasciatus, Arion hortensis, and Zonitoides nitidus represent new host records for C. dukae.

In this study, we present an analysis of the ecto- and endoparasite fauna of Zyzomys argurus from Queensland and the Northern Territory. The finding of the louse Hoplopleura zyzomydis, and the nematodes Syphacia abertoni and S. boodjamullaensis, together with the new host records for Nippostrongylus sp., Aspiculuris tetraptera and Raillietina sp., have increased the number of parasites known from Z. argurus from 18 to 24, and provide the first records of parasites from Z. argurus from central and eastern Australia. Analysis of the assemblage of parasites found from Z. argurus appears to indicate that, while intraspecific transmission of parasites is relatively common, host-switching from other species is not. The ecology of Z. argurus appears to be the main determinant of its depauperate parasite fauna.

New Host Records

The northern hairy-nosed wombat Lasiorhinus krefftii is now restricted to a single population of less than 70 individuals at Epping Forest National Park, North Queensland, Australia, and is listed as critically endangered. We examined six trapped animals for ectoparasites, and 197 faecal samples for endoparasites. All ectoparasites (the tick Ambylomma triguttatum, the flea Echidnophaga cornuta and the louse Boopia dubia) were new host records. Nematode eggs and larvae were found in every faecal sample and the number of eggs varied significantly among months sampled. Cestode proglottids were also found. There was no indication that parasites were causing disease and few species were detected. This last remaining population of L. krefftii may be relatively immunologically na�ve, and we suggest that removing them from their natural environment to other areas as part of a captive breeding program should be attempted with caution.

New Host Records

The rhinonyssid and kytoditid mite fauna in the endangered finch E. gouldiae and 6 co-occurring species (long-tailed finches (Poephila acuticauda), masked finches (P. personata), pictorella manikins (Heteromunia pectoralis), zebra finches (Taeniopygia guttata), double-barred finches (T. bichenovii) and budgerigars (Melopsittacus undulatus)) in Northern Territory, Australia, were surveyed over a 3-year period to assess prevalence and intensity of infection and to determine the stability in these parameters over space and time. These data were used to examine the likelihood that prevalence and intensity of infection by the rhinonyssid mite Sternostoma tracheacolum in E. gouldiae are in any way aberrant. 12 new host records for rhinonyssid and kytoditid mites are reported from 2 localities in the Northern Territory. Kytonyssus andrei is a new genus record and S. paddae and Kytodites amandavae are new species records for Australia. S. tracheacolum was found to infect E. gouldiae, P. personata, M. undulatus and H. pectoralis. The other nasal mites found were Sternostoma sp., Ptilonyssus astrildae, P. neochmiae and P. emberizae. Prevalence and intensity of infection with S. tracheacolum were significantly higher in E. gouldiae than in Poephila personata and M. undulatus, but were not significantly higher than those found in H. pectoralis. The frequency distribution of infrapopulation sizes of S. tracheacolum in pooled E. gouldiae samples was significantly different from that found in pooled M. undulatus and P. personata samples but not from pooled H. pectoralis samples. Prevalence and intensity of infection by rhinonyssid mites in E. gouldiae were significantly higher than infection in all other host species examined, except H. pectoralis. Significant increases in the intensity of infection in H. pectoralis were detected between 1992-94, suggesting that this species may also be under threat from parasitism by S. tracheacolum.

<p>In 51 specimens of lane snapper, <em>Lutjanus synagris</em>, captured in Santiaguillo Reef, Veracruz Reef National Park System, State of Veracruz, in the Southern Gulf of Mexico, a total of 25 helminth species were recovered, as follows: 9 digeneans (8 adults, and 1 metacercaria), 7 monogeneans, 6 nematodes (4 adults, and 2 larvae), 2 cestodes (both larvae), and 1 acanthocephalan (juvenile). Out of the 25 species, 11 are new host records; 2 have prevalence &gt; 50%, and mean intensity &gt; 4.7; <em>Haliotrematoides cornigerum</em> (monogenean) had the highest prevalence, 94.11%, followed by <em>Euryhaliotrema tubocirrus </em>with prevalence of 66.67%. Richness (<em>S</em> = 25) and diversity (Shannon index <em>H’</em> = 2.13) at component community, and endoparasites infracommunity level (<em>S</em> = 6.27 ± 2.5, Brillouin index<em> H</em> = 1.07 ± 0.42), and ectoparasites infracommunity level (<em>S</em> = 3.6875 ± 1.87, Brillouin index <em>H</em> = 0.74 ± 0.4), were similar to those found in other marine fish. Results suggests that the host feeding habits determine the endoparasites composition, while the ectoparasites composition is associated to the environmental conditions.</p>

Eighty-one H. chrysogaster from nineteen localities in Victoria and South Australia were examined for helminths. One acanthocephalan Corynosoma stanleyi: and one cestode, Hymenolepis diminuta, were found. Of the trematodes six were identified to species: Echinoparyphium hydromyos, Fibricola minor, F. intermedius, Microphaflus minutus, Maritrema oocysta and Plagiorchis jaenschi; two were placed in the families Heterophyidae, and Psilostomidae, both new locality records; and two new species Notocotylus sp. nov. and Paramonostomum sp. nov. were found. There were six nematode species: Synhimantus australiensis, Antechiniella suffodiax, Antechiniella sp., Woolleya hydromyos as well as Parastrongyloides sp. and a heteroxynematid both new host records. H. diminuta was the most prevalent helminth, with M. minutus and S. australiensis the most prevalent trematode and nematode respectively. A checklist of helminths from H. chrysogaster is given and comparisons between infections of Tasmanian, Victorian and South Australian hosts are made. Thirty-three of these water rats, trapped live in Victoria, were also examined for protozoa. Klossiella hydromyos, Toxoplasma gondii and Sarcocystis sp. were found. Twenty of the Victorian hosts were examined for ectoparasites. Three mites; Paraspeleognathopsis derricki, Murichirus parahydromys, and Radfordia sp.; one tick, Zxodes tasmani; one louse, Hoplopleura bidentata; and three flea species, Acanthopsylla rothschildi and Echidnophaga spp. were found.

Fire has a long history in Australia and is a key driver of vegetation dynamics in the tropical savanna ecosystems that cover one quarter of the country. Fire reconstructions are required to understand ecosystem dynamics over the long term but these data are lacking for the extensive savannas of northern Australia. This paper presents a multiproxy palaeofire record for Marura sinkhole in eastern Arnhem Land, Northern Territory, Australia. The record is constructed by combining optical methods (counts and morphology of macroscopic and microscopic charcoal particles) and chemical methods (quantification of abundance and stable isotope composition of pyrogenic carbon by hydrogen pyrolysis). This novel combination of measurements enables the generation of a record of relative fire intensity to investigate the interplay between natural and anthropogenic influences. The Marura palaeofire record comprises three main phases: 4600–2800 cal BP, 2800–900 cal BP and 900 cal BP to present. Highest fire incidence occurs at ~4600–4000 cal BP, coinciding with regional records of high effective precipitation, and all fire proxies decline from that time to the present. 2800–900 cal BP is characterised by variable fire intensities and aligns with archaeological evidence of occupation at nearby Blue Mud Bay. All fire proxies decline significantly after 900 cal BP. The combination of charcoal and pyrogenic carbon measures is a promising proxy for relative fire intensity in sedimentary records and a useful tool for investigating potential anthropogenic fire regimes.
