Whan, I., G. Bortolussi, and R. Backus. "The impact of innovation on beef production in far northern Australia." Australian Journal of Experimental Agriculture 46, no. 2 (2006): 271. http://dx.doi.org/10.1071/ea05175.
Abstract:
In this paper we examine the forces that have shaped Australia’s far northern (north of 20° south) beef industry over the past 35 years. This is done for the purpose of tracing its transformation from a state of relative isolation to an integral part of the national beef industry. We note that integration is being accompanied by a greater focus, particularly by corporate producers, on specialised breeding in the far north and this is being assisted by innovations that increase herd fertility and raise the meat quality of the progeny, while retaining adaptation of the breeding herd to the local environment. Among a range of technologies, genetic improvement has significant potential to bring about rapid improvement in the meat quality of tropically adapted cattle. With respect to gene-based technology, however, independent producers will have to be convinced about the rigour of the technology and the prospects of economic gains before they make significant management changes. To this end, innovative marketing systems are needed that will reveal the link between expected meat returns and the offer prices applying to groups of growing cattle in any location. Accordingly, there is an urgent need to develop and introduce a descriptive and informative trading language for growing cattle that incorporates inherent qualities including those that influence meat quality. Innovations that will complement those applying to enhancement of meat quality are more general but will significantly raise herd productivity. We also compare the operating systems of both corporate and independent producers in the region.

Copley, P. B., and P. J. Alexander. "Overview of The Status of Rock-wallabies in South Australia." Australian Mammalogy 19, no. 2 (1996): 153. http://dx.doi.org/10.1071/am97153.
Abstract:
The status of Yellow-footed Rock-wallabies (Petrogale xanthopus) and Black-footed Rock-wallabies (P. lateralis) in South Australia was assessed by comparing recent survey and census data with previously collated information about the distribution and relative abundance of each taxon. Petrogale xanthopus has maintained most of its known geographic range within the state; however, its relative abundance has declined significantly and 35 (or 15%) of a total of 229 recorded colonies have become extinct since European settlement. Eight of these colony extinctions have occurred over the past 25 years; three of them since 1981. As this species is continuing to decline it should be regarded as threatened within the state. Petrogale lateralis has at least two sub-species which occur in South Australia. Petrogale lateralis pearsoni is endemic to the state and occurs on offshore islands. Since 1960 its natural occurrence of about 3-500 individuals on North Pearson Island has been expanded to four other islands through translocations and the total population is now about 700-1100 animals. This subspecies, while not occurring in large numbers, is nonetheless relatively secure due to the additional populations established and the fact that these are on islands isolated from most mainland threats. The mainland subspecies, Petrogale lateralis MacDonnell Ranges race, by comparison has suffered a drastic reduction in both geographic range and abundance to the point where it is South Australia’s most critically endangered vertebrate taxon. It has declined from being a very common species in the state’s far north- west to only two known, widely separated, colonies which total less than 100 animals between them. Management and research recommendations are provided.

Abstract:
Every year, millions of migratory birds journey along the East Asian-Australasian Flyway (EAAF). The scope of the EAAF encompasses Asia Pacific nations like Australia, New Zealand, China, Japan, South Korea, Vietnam, Malaysia and Indonesia. The effective conservation of these birds rests upon the implementation of bilateral legal agreements as well as non-binding regional initiatives along this North-South nexus. This article evaluates the implementation of one of the most important bilateral bird agreements in the region – the China-Australia Migratory Bird Agreement (CAMBA). The main obligations in CAMBA are identified; as are the legal initiatives adopted by both China and Australia which reflect CAMBA's obligations. Whilst Australian law makes specific reference to CAMBA, Chinese law is far less direct, though perhaps no less effective. The argument is made that the findings in this article have relevance for an improved understanding of the mechanisms for transboundary governance of migratory birdlife, especially in the Asia Pacific.

Abstract:
Specimens of Phebalium glandulosum Hook. subsp. glandulosum representing the entire geographic range of the subspecies were examined for morphological and anatomical variation. Phenetic patterns were identified with the pattern analysis package PATN, and three distinct groups were identified. One group consists of plants from inland areas of New South Wales, north-western Victoria, and the Yorke and Eyre Peninsulas of South Australia; a second group consists of plants collected from alongside the Snowy River in eastern Victoria and south-eastern New South Wales; and a third group consists of plants from Queensland and northern New South Wales. The climate analysis program BIOCLIM was used to compare climate variables across the geographic range, and showed clear climatic separation in support of the phenetic analysis. The three groups are formally recognised here as distinct subspecies. Plants from Queensland and the Bourke region of northern New South Wales belong to the typical subspecies; plants from north-western Victoria, central New South Wales, and the Yorke and Eyre Peninsulas of South Australia form a cohesive assemblage and are recognised as a new subspecies P. glandulosum subsp. macrocalyx; and plants from the Snowy River in far eastern Victoria and the Southern Tablelands of New South Wales form a distinct and isolated group recognised as a new subspecies P. glandulosum subsp. riparium. These new subspecies are formally described, and an identification key and summaries distinguishing all six subspecies of P. glandulosum are presented.

Abstract:
Two species of rock-wallabies occur in New South Wales; the Yellow-footed Rock-wallaby Petrogale xanthopus in the far west and the Brush-tailed Rock-wallaby Petrogale penicillata in the east. Both species have contracted in distribution and abundance across their former range and are threatened in NSW. The P. xanthopus population in NSW now comprises only two sub-populations. Removal of large numbers of goats, thought to be the primary threat, has not halted the wallaby's decline. Fox and cat predation is now considered the major threat. Fox control is currently being conducted. P. penicillata has undergone a dramatic and continuing decline from being common throughout south-eastern Australia to currently being extremely rare in the southern and western parts of its range and found only in isolated colonies throughout the north of its range. Predation (particularly fox, but including dog and cat), once again, is considered the major threat. A recovery program has been commenced involving the media and wider community in locating extant colonies, as well as developing and implementing Population Management Plans. This program has documented further local extinctions and extremely low numbers of individuals in colonies in the southern and western parts of the range. While no surviving colonies are known between the Shoalhaven area and the Victorian border, there remain more and larger colonies in the north of the state.

Abstract:
Provision of information for the purposes of evaluating and monitoring recreation and tourism land use is a conceptually difficult task for economists and land managers. A range of techniques has been developed since the pioneering work of Clawson and Knetsch in the 1960s to estimate the market value of recreation and tourism in natural areas. These techniques involve a number of conceptual and practical difficulties when used for environmental auditing and evaluation purposes. This article outlines the process of evaluating recreation and tourism on public lands in order to provide information for an environmental audit of the Upper North East region of New South Wales. The range of market and non-market values associated with tourism and recreation on public lands is based on existing studies of the region. The values of commercial production, recreation and tourism on public lands are compared within a structural model (input–output) of the regional economy.

Watson, Mandy, Kasey Stamation, and Claire Charlton. "Calving rates, long-range movements and site fidelity of southern right whales (Eubalaena australis) in south-eastern Australia." J. Cetacean Res. Manage. 22, no. 1 (July 1, 2021): 17–28. http://dx.doi.org/10.47536/jcrm.v22i1.210.
Abstract:
Within New Zealand and eastern Australia, over 58,000 southern right whales were harvested by commercial whalers between 1790 and 1980, with approximately 19,000 harvested from south-eastern Australia. Local extirpation is believed to have led to a loss of cultural memory of calving areas, contributing to the limited recovery of the south-eastern Australian population. While the number of whales observed using the south-eastern Australian coastline is increasing, there has been no change over three decades in the annual abundance of cow-calf pairs at Logans Beach in Warrnambool, Victoria, the only established calving ground in the region. Knowledge of life history parameters of the south-eastern Australian population is lacking. Here, we examine sightings and photo-identification data from southern Australia to investigate calving intervals, long range movements and fidelity to the Logans Beach nursery ground. Sightings data revealed at least 93 calves were born at Logans Beach between 1980 and 2018 (an average of 2.6 per year) with a mean calving interval of 3.5 ± 1.0 years (± SE, n = 34). Comparison between photo-identification catalogues compiled for south-eastern and south-western Australian populations shows that southern right whales are wide ranging within southern Australian waters. Females can be sighted at locations as far apart as 3,800 km across seasons and there is overlap in the wintering range of the south-eastern and south-western populations, with at least 7% of whales using both regions. We also provide the first report of an Australian southern right whale female with strong site fidelity to a calving area in one region relocating long-term to a calving area in another region. This work highlights several knowledge gaps, such as; the location of feeding and conception grounds for this population as well as the degree of mixing between the two Australian populations outside their wintering areas. In addition, the proportion of female calves born at Logans Beach returning to their natal site to calve remains unclear. Our work provides the first assessment of calving rates, movement and site fidelity within the south-eastern Australian population, critical for understanding constraints to recovery and informing conservation management of southern right whales in Australia. Targeted, long-term monitoring programs across the south-eastern Australian region are needed to provide demographic information on which to base predictions of the impacts of anthropogenic threats such as noise disturbance, entanglement and vessel strike.

Barrett, Russell L. "Examining range disjunctions in Australian Terminalia (Combretaceae) with taxonomic revision of the T. canescens and T. cunninghamii species complexes." Australian Systematic Botany 28, no. 1 (2015): 23. http://dx.doi.org/10.1071/sb14026.
Abstract:
Several range disjunctions have been identified in the Australian species of the genus Terminalia L. Field studies and examination of herbarium specimens of taxa with range disjunctions have demonstrated that taxonomic changes are justified. Detailed morphological studies of the Terminalia canescens (DC.) Radlk. species complex showed that four taxa should be recognised. The name Terminalia circumalata F.Muell. is resurrected as a taxon endemic to the Pilbara region, with T. canescens not occurring in that region. The distinction of Terminalia bursarina F.Muell., T. canescens and T. pterocarya F.Muell. is also supported. Terminalia cunninghamii C.A.Gardner has been considered to have a disjunct range between the far north and south-west of the Kimberley region of Western Australia. Terminalia kumpaja R.L.Barrett is described as a new species to accommodate the disjunct southern populations because morphological examination has shown them to be distinct. Terminalia kumpaja is restricted to the Dampier Botanical District. Full descriptions and illustrations of key identifying features are provided for these species. Keys to all Australian Terminalia species are presented. Additional species with disjunct distributions that warrant further study are noted. Lectotypes are selected for Terminalia circumalata and T. rogersii W.Fitzg.

Abstract:
The helminth fauna from 124 water-rats, Hydromys chrysogaster, collected from 33 localities in Queensland was analysed. A total of 45 species of helminths was found, comprising 2 acanthocephalans, 2 cestodes, 13 nematodes and 28 trematodes. The helminth community of the water-rats in the region north of latitude 18˚ (far north) was different from that of water-rats south of 18˚ (central); Sorensen’s Index 45·8% similarity, whereas Holmes and Podesta’s Index gave 32·1% similarity. Comparisons with data from water-rats from southern and Tasmanian regions showed that they were different from each other and from both Queensland regions. The helminth communities were characterised by high diversity, dominated by trematodes in the central and Tasmanian regions, but with nematodes becoming more prominent in the far northern and southern regions. No core or secondary species were found in the Queensland helminth communities, the southern community was suggestive of a bimodal distribution and the Tasmanian had two core species. A checklist of helminth species occurring in water-rats from eastern Australia is provided.

Abstract:
Marine turtles regularly migrate hundreds to thousands of kilometres between nesting beaches and home foraging grounds. Effective conservation of marine turtles requires understanding of migration patterns in order to facilitate regional cooperation across the turtles' migratory range. Indigenous Australians maintain traditional rights and responsibilities for marine turtle management across much of the northern Australian coast. To better understand turtle migrations and identify with whom the Aboriginal people of north-east Arnhem Land (Yolngu) share turtles, we used satellite telemetry to track the migration routes of 20 green turtles (Chelonia mydas) departing from a nesting beach ~45 km south of Nhulunbuy, north-east Arnhem Land, Northern Territory, Australia. All tracked turtles remained within the Gulf of Carpentaria. These results suggest that the foraging habitat for adults of this nesting population may be largely confined to the Gulf, offering an optimistic scenario for green turtle conservation. Given these results and the critical role indigenous people play in conserving and managing marine turtles, we recommend that a formal network of indigenous communities be established as the foundation of a community-based turtle-management strategy for the Gulf of Carpentaria region.

Abstract:
Accompanying CD-ROM inside back cover, includes Appendices. Bibliography: leaves 242-266. This thesis examines the effects on vegetation at selected sites in northern South Australia of excluding various herbivores over a four and a half year period and of two intense but controlled grazing pulses over a six month period followed by an 18 month recovery period in a dune-swale land system. These changes are compared with changes recorded over an 11-year period at the Olympic Dam mine site. It found that short-term changes in vegetation revealed by ordination of periodical cover, density and species richness, are attributable to the periodicity of rainfall and that, under present grazing regimes, rainfall effects override grazing effects. Differences between the effects of sheep and cattle hoof damage are worthy of further investigation, as is the impact of kangaroo grazing. These two factors may have important implications for the management of Australian rangelands.

Douglas, Kirsty. Pictures of Time Beneath. CSIRO Publishing, 2010. http://dx.doi.org/10.1071/9780643100251.
Abstract:
Pictures of Time Beneath examines three celebrated heritage landscapes: Adelaide’s Hallett Cove, Lake Callabonna in the far north of South Australia, and the World Heritage listed Willandra Lakes Region of New South Wales. It offers philosophical insights into significant issues of heritage management, our relationship with Australian landscapes, and an original perspective on our understanding of place, time, nation and science.
Glaciers in Adelaide, cow-sized wombats, monster kangaroos, desert dunes littered with freshwater mussels, ancient oases and inland seas: a diverse group of deep-time imaginings is the subject of this ground-breaking book. Ideas about a deep past in Australia are central to broader issues of identity, belonging, uniqueness, legitimacy and intellectual community. This journey through Australia’s natural histories examines the way landscapes and landforms are interpreted to realise certain visions of the land, the nation and the past in the context of contemporary notions of geological heritage, cultural property, cultural identity and antiquity.
