In Australia, baiting with 1080 (sodium fluoroacetate) is widely used to reduce predation of native wildlife by the red fox. However, such control programs may place some native carnivores at risk, particularly the spotted-tailed quoll in eastern Australia. We measured the mortality in a total of 57 quolls fitted with mortality radio-transmitters during four experimental fox baitings with Foxoff® 1080 baits containing Rhodamine B in north-east New South Wales. In all experiments quolls visited bait stations regularly and removed a total of 20 baits. All but one of these baits was found in the vicinity of the bait station, indicating that quolls did not ingest baits. This was confirmed by the absence of Rhodamine B in the vibrissae of all quolls retrapped after baiting. The only quoll that may have died from a bait had eaten a cached bait some six weeks after baiting concluded. Thus, baiting did not threaten any of the quoll populations sampled. Therefore it appears that most restrictions imposed to protect spotted-tailed quolls during fox baiting are unnecessary as long as this bait type is used.

The removal of non-toxic baits was monitored during a simulated trail-baiting programme for foxes and wild dogs in the central tablelands of New South Wales. Ninety-one buried baits were removed by a number of species including spotted-tailed quolls, Australian brush-turkeys, superb lyrebirds, small mammals, wild dogs and a red fox. Spotted-tailed quolls were significantly less likely to remove baits buried under the ground surface than baits buried in raised mounds of soil. By means of remote photography, individual quolls were identified removing 3–4 baits in one night from bait stations 400 m apart. The results of this study show that spotted-tailed quolls and other non-target species may face substantial risk of consuming baits intended for wild dogs and foxes. However, the risk of poisoning spotted-tailed quolls may be significantly reduced by appropriate planning. Recommendations are made to increase the target-specificity of baiting programmes in areas with populations of spotted-tailed quolls.

Melaleuca Leucadendra

Nematodes of the genus Fergusobia Currie (Tylenchida : Neotylenchidae) and flies of the genus Fergusonina Malloch (Diptera : Fergusoninidae) together form the only known mutualistic association between insects and nematodes that induces galls in young meristematic tissues in Myrtaceae. Six new species of Fergusobia are described (F. quinquenerviae, sp. nov., F. cajuputiae, sp. nov., F. dealbatae, sp. nov., F. leucadendrae, sp. nov., F.�nervosae, sp. nov., and F. viridiflorae, sp. nov.) and partial descriptions are presented for a further two species. Together, these taxa form a putative monophyletic group, apparently restricted to species of Melaleuca in the broad-leaved M. leucadendra-complex, from coastal Queensland and north-east New South Wales, Australia. Each species of nematode has a mutualistic association with a particular species of Fergusonina fly and (with one exception) each association is apparently restricted to one particular species of Melaleuca.

We present the first photographic evidence of the presence of the giant manta ray Manta birostris in east Australian waters. Two individuals were photographed off Montague Island in New South Wales and off the north east coast of Tasmania, during summer 2012 and 2014, respectively. These sightings confirm previous unverified reports on the species occurrence and extending the range of M. birostris to 40ºS. We discuss these findings in the context of the species’ migratory ecology, the regional oceanography along the south eastern Australian coastline and local productivity events.

Results from a long-term radio-tracking study of pteropodid fruit-bats are reported. Grey-headed fruit bats (Pteropus poliocephalus) captured from seven colonies in eastern New South Wales, Australia, were fitted with collar-mounted radio transmitters to permit their movements to be monitored over the following year. The sheepskin-lined leather collars were well tolerated by the bats over periods of 6-18 months. Bats moved between major colony sites for distances of up to 750 km, with movements occurring in both northerly and southerly directions. One bat from Lismore had a feeding range of 25 km, whereas in Sydney bats flew up to 17 km each night to feeding sites. There was considerable interchange between bats in adjacent colonies.

Surveys for juvenile Mythimna convecta throughout the agricultural and arid regions of eastern Australia were conducted from 1986 to 1989. Armyworm populations north of 33 degrees S were generally dominated by M. convecta, and further south by Persectania ewingii. M. convecta was most widely distributed in spring. Incidence during autumn and winter ranged from very low in Victoria to high in northern New South Wales and southern Queensland. Summer infestations were found mostly on the south-east coast where favourable habitats were abundant. Colonised habitats included extremely arid regions, where small numbers of larvae were associated with grasses in temporary watercourses, and the higher-rainfall, eastern regions. The largest infestations occurred in south-east Queensland and north central and north-east New South Wales, particularly after heavy autumn rains. There appeared to be two generations of M. convecta over the autumn/winter period: the first a synchronised event starting on the autumn rains and the second commencing in June/July and comprising a wide spread in age distribution. The progeny of the winter generation are probably the source of most economic outbreaks. Mythimna convecta larvae were collected from subtropical and temperate grasses. In the former, most larvae were found in tussocks, particularly of Dichanthium sericeum and Chloris truncata, which provided a dense, fine-leaf crown and canopy. After good autumn rainfall and vegetative growth, the wiry-stemmed tussocks, including Astrebla spp. and C. ciliaris, were also common hosts. The temperate grasses, particularly Avena fatua and Hordeum leporinum, were the main winter hosts although the greatest densities were found only in thick swards of growth, particularly those that contained dried grass. Two of the largest surveys, in autumn 1987 and 1988, followed periods of heavy rain and provided strongly contrasting results. The 1987 survey of central and south-west Queensland located no M. convecta larvae, indicating that densities were below detection thresholds. The paucity of larvae was attributed to lack of suitable atmospheric conditions to assist moth immigrations and absence of adequate populations in potential source areas. The 1988 survey revealed a major outbreak of M. convecta larvae in south-east Queensland and northern New South Wales. The area received record rains during early April of that year, and the outbreak probably arose from moth migrations from the east and south-east coast. An outbreak of similar scale occurred after further heavy autumn rains in 1989.

The movement patterns of ten feral goats fitted with radio transmitters were examined over a 20 month period in a semi-arid woodland of western New South Wales. The mean distance between locations (fixes) was 3.1 km at 42 day intervals. The mean interfix distance for male goats was 1.1 km greater than for females. The mean home range for the five males was 29.4 km2 and 10.9 km2 for the five females (95% convex polygon). The movement patterns of feral goats in this woodland system were predictable. Goats usually moved small distances and remained close to intermittent lakes and creeks with abundant tree and shrub cover. Goats commercially harvested in this area were likely to have come from local populations living in an area of 15-35 km2, an area encompassed by 1-2 paddocks on a single property.

Wide Road

The installation of glide poles to enable gliding mammals to cross wide road corridors has become a common feature of highway upgrades in eastern Australia. While frequent use by small species has been well documented, records of use by large glider species are scant. During 15 months of camera monitoring of two glide poles in the median of the Pacific Highway at Halfway Creek, north-east New South Wales, yellow-bellied gliders (Petaurus australis) were detected on nine occasions. On three of these occasions, video footage captured glide launches across the northbound carriageway. Our study provides the first definitive evidence of repeated use of wooden glide poles by the yellow-bellied glider to cross a highway corridor. Glide poles, therefore, have the potential to restore functional connectivity for yellow-bellied gliders at locations where major roads bisect forest habitat.

Tracking Period

During 1970-74, radio transmitters were attached to five adult and four juvenile dingoes trapped on the escarpment 50 km east ofArmidale, N.S.W. These animals were radio-tracked for a total of 515 (10-83) days, and 4058 fixes (6-1248 per animal) were obtained. Some of the animals were tracked almost continuously for periods of 100 h. The dingoes exhibited two types of movement: one, dubbed searching movement, appeared to be associated with hunting; the other, dubbed exploratory movement, was used when shifting the hunting locality and in traverses of the home range. These traverses are postulated to be related to maintaining communication between animals. The dingoes were active throughout the day with peaks of activity at dawn and dusk. The distances travelled per hour in the diurnal and nocturnal periods were equal. Activity periods were short (65% <1 hour) and interspersed with shorter rest periods. During the radio-tracking period, the average home range of adults was 2700 ha. There was evidence that this size of range did not increase over periods longer than the radio-tracking. The implications of this for control programs are discussed.

Bait Stations

Novel bait stations can be used as a targeted method of delivering bait by exploiting behavioural traits of the target species. On Muttonbird Island, New South Wales, the black rat (Rattus rattus) has been baited to aid the conservation of the island’s wedge-tailed shearwater (Ardenna pacifica) colony, which may result in poisoning of the sympatric swamp rat (Rattus lutreolus). We aimed to design a bait station that R. rattus could reach, but that R. lutreolus could not. We found that 11 (92%) of 12 captive R. rattus reached the bait chambers by climbing a 50-cm vertical pipe, whereas only four (18%) of 22 R. lutreolus reached these bait stations. In a field trial on Muttonbird Island R. rattus entered the bait chamber on an average of 5.3 events per night of vertical bait station deployment, but R. lutreolus did not enter the stations. In a field trial on the mainland at a site with a high density of R. lutreolus, this species was detected in one vertical bait station five times, equating to an average of 0.017 events per night of vertical bait station deployment. We conclude that R. rattus readily climbs a 50-cm pipe to enter the bait station, whereas R. lutreolus rarely or never does on Muttonbird Island or at the mainland site.
