Transmitter Design

Regulation of the world’s rivers has permanently altered the natural flow regime in many systems. Australia’s rivers have also been subject to extensive modification; however, little is known of the effect altered flows have on many native fish species. Active transmitters offer an effective method of monitoring fish movement but there is little information on tag retention and post-tagging survival for most Australian species. Four fish species from the north-eastern rivers of New South Wales were surgically implanted with dummy transmitters to determine retention and incision healing rates. Eel-tailed catfish (Tandanus tandanus) were implanted with three types of dummy radio transmitters and the transmitter with the shortest externally exited antenna is recommended. In Australian bass (Macquaria novemaculeata), low water temperature, abdominal distention in females and the breakdown of dissolvable sutures contributed to the expulsion of dummy acoustic transmitters. Freshwater mullet (Myxus petardi) and sea mullet (Mugil cephalus) were implanted with dummy acoustic transmitters and healing rates were different between the two species. The present study demonstrated species specificity in tag suitability and recovery rates, the advantages of quarantining fish before release following the surgical implantation of transmitters and the value of controlled experiments to determine optimal transmitter design and post-operative conditions.

A New Species

A new species, Eucalyptus fusiformis Boland et Kleinig, from the north coast of New South Wales is described. Its taxonomic position is in E. subgenus Symphyomyrtus series Paniculatae following the informal classification of eucalypts proposed by Pryor and Johnson (1971). E. fusiformis is characterised by its flowers, fruits and adult leaves. In the bud the staminal filaments are fully inflected while the androecium has outer staminodes and the anthers are cuboid and adnate. The fruits are narrow, often truncate fusiform, tapering into long slender pedicels. The adult leaves are dull grey, concolorous and hypoamphistomatic. The species resembles the more numerous and often co-occurring ironbark E. siderophloia which has similar adult and seedling leaves. The volatile oils of both species are very similar. The ecology, distribution, taxonomic affinities and conservation status are discussed.

Autumn And Winter

The diet of the squirrel glider (Petaurus norfolcensis) was described by qualitative observations of feeding behaviour at a floristically rich site on the north coast of New South Wales. Twelve gliders from six groups were examined over a 10-month period. Flowering and bark-shedding data were also collected. Nectar and pollen were the most important food resources and accounted for 59% of all observations. Banksia integrifolia was the most important source of these foods, but eucalypts were used heavily when in flower and several other genera were also visited. Feeding on arthropods constituted 26% of all feeding observations. Arthropods were harvested in all months of the study from a variety of substrates. Feeding on arthropods was relatively unimportant in May and June when pollen ingestion was presumed to be high. Honeydew was used but was absent from the diet during winter. Acacia gum was obtained from two species in autumn and one, Acacia irrorata, was incised to promote gum production. Corymbia intermedia and Angophora woodsiana were incised for sap in autumn and winter. Sap flows resulting from insect (borer) damage on other species were also used. Fruit, Acacia seeds and arils, and lichens were consumed on a few occasions. The squirrel glider displayed seasonal trends in feeding behaviour that, in part, accorded with observed phenological patterns. The foods used by the squirrel glider during this study were similar to those previously reported for the genus. However, few studies have documented such a diversity of dietary items at one site. Management of the squirrel glider appears to require the maintenance of floristic diversity, and particularly the persistence of midstorey species.

The marine benthic red algae of the Coffs Harbour region are described and illustrated in detail. The survey constitutes the first ever detailed descriptive and illustrative mainland regional monograph of any area along the entire eastern Australian seaboard. Collections made intertidally and to depths of 20 m have included 119 species in 74 genera, 26 families, and 8 orders of Rhodophyta, of which 54 (45%) were previously unrecorded from eastern Australia, 22 (18%) are new records for the whole of Australia (16 being new Southern Hemisphere records), 1 (Dictyothumnion) constitutes a new genus, and 16 (13%) are new species in the genera Gracilaria, Curdiea, Botryocladia, Dictyothamnion, Antithamnion, Ceramium, Callithumnion, Anotrichium, Nitophyllum, Phycodrys, Apoglossum, Dasya, Fernandosiphonia, and Herposiphonia. Also included are major Australian revisions of the genera Martensia and Nitophyllum, and six new combinations are proposed (Chondria infestans, Curdiea angustata, Dasya pilosa, Haraldiophyllum sinuosum, Myriogramme pulchellum, and Stenograrnme phyllophoroides). The Coffs Harbour flora, although related to the north-eastern and, to a lesser degree, southern Australian floras, has a number of species previously known only from much more remote localities, such as Japan (6 species), California (4 species), New Zealand (3 species), India (2 species), South America (2 species), the Galapagos Islands (1 species), China (1 species), South Africa (1 species), and the Mediterranean (1 species). Twelve of the 22 species newly recorded for Australia show a definite western Pacific distribution, a region with which the overall Coffs Harbour flora has strong affinities.

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.

Cattle And Sheep

Two State-wide surveys were carried out in 1978 to detect bluetongue (BLU) virus antibody in cattle and sheep sera in New South Wales (NSW). The first survey showed that BLU group antibody in cattle 18-24 months old was confined to the coastal regions (east of the Great Dividing Range) and the Hunter Valley. However, in the second survey, of cattle more than 5 years old, reactors were much more widely distributed over the north-eastern third of the State and into the western division with prevalences up to 85% in some areas. In contrast, very few reactors were detected in sheep in either survey (less than 1 % of the sheep sera tested).

The Impact

Inputs and losses from Giant Parramatta grass [GPG, Sporobolus indicus (L.) R. Br. var. major (Buse) Baaijens] soil seed banks were quantified on the North Coast of New South Wales. Monthly potential seed production and actual seed fall was estimated at Valla during 1991-92. Total potential production was >668 000 seeds/m2 for the season, while seed fall was >146000 seeds/m2. Seed fall >10000 seeds/m2.month was recorded from January until May, with further seed falls recorded in June and July. The impact of seed production on seed banks was assessed by estimating seed banks in the seed production quadrats before and after seed fall. Seed banks in 4 of the 6 sites decreased in year 2, although seed numbers at 1 damp site increased markedly. Defoliation from mid-December until February, April or June prevented seed production, reducing seed banks by 34% over 7 months. Seed banks in undefoliated plots increased by 3300 seeds/m2, although seed fall was estimated at >114 000 seeds/m2. Emergence of GPG seedlings from artificially established and naturally occurring, persistent seed banks was recorded for 3 years from bare and vegetated treatment plots. Sown seeds showed high levels of innate dormancy and only 4% of seeds emerged when sown immediately after collection. Longer storage of seeds after collection resulted in more seedlings emerging. Estimates of persistent seed banks ranged from 1650 to about 21260 seeds/m2. Most seedlings emerged in spring or autumn and this was correlated with rainfall but not with ambient temperatures. Rates of seed bank decline in both bare and vegetated treatment plots was estimated by fitting exponential decay curves to seed bank estimates. Assuming no further seed inputs, it was estimated that it would take about 3 and 5 years, respectively, for seed banks to decline to 150 seeds/m2 in bare and vegetated treatments.
