A Lopingian (Late Permian) brachiopod fauna from the Qubuerga formation at Shengmi in the Mount Qomolangma region of Southern Xizang (Tibet), China

A small fauna of 11 species belonging to 10 genera of Permian Brachiopoda from the lower part of the Qubuerga Formation outcropping near Shengmi village in the Qomolangma region of southern Xizang (Tibet) is figured and new taxa are described. New taxa are Quinquenella semiglobosa and Costatumulus shengmiensis. The fauna is most likely of Wuchiapingian (Djhulfian) age as indicated by the majority of the brachiopod species.

Physical activity in three regional communities in Queensland

Objective
To describe physical activity participation in three Queensland regional communities.

Design
Cross-sectional mail survey of randomly selected residents, stratified by age and sex.

Setting
Esk, Mareeba and Mount Isa.

Participants
1219 (58% women) adults, with a mean age 46.7 (standard deviation 14.7) years.

Main outcome measures
Proportion of people inactive, meeting Australian activity guidelines (a minimum of 150 min week−1 and five sessions week−1) and walking a dog daily; time spent walking and cycling for transport; location and type of recreational physical activities.

Results
Overall, 18% of respondents were inactive, with the highest proportions among women (22.3%) and older adults in Mount Isa (24.3%). The proportion meeting activity guidelines was 47%, with the lowest proportion among women in Mount Isa (40.4%). Although 63% reported owning a dog, only 22% reported walking a dog daily. Few people reported walking or cycling for transport. The most common types of activities were walking, home-based exercise, running/jogging and swimming, and the most common location was at or near home.

Conclusions
Physical activity levels were lower in these regional communities than the state average. The findings indicate a need for physical activity policy and intervention strategies targeting regional and rural areas. This could focus on women and older adults, dog walking and physical activity opportunities in or near the home.

The challenges of addressing an Aboriginal responsibility for Country in land-use and national park planning: a South East Queensland case study

This paper presents research insights on the challenges that Australian Aboriginal communities living within the South East Queensland (SEQ) metropolitan region face in seeking to exercise their contemporary responsibilities to care for Country in land-use and national park planning. A case study design was adopted to analyse the incorporation of two Aboriginal communities connections to Country in state-based planning systems, and to explore the responsibilities Aboriginal communities ethically seek to adhere to in maintaining Country from their own understandings.
Country, from an Aboriginal understanding, involves a deep ecological, cultural, economic and social comprehension of ‘law’ guided by a responsibility for Country. Otherwise known as customary law and custom, Country is that which both Aboriginals and their communities are intrinsically connected to. Country is the moral value that guides Aboriginal obligation to care and this obligation could well conflict
with mainstream contemporary Western management policy and legislation.
This research draws on insights from Quandamooka Country (North Stradbroke Island) and Jagera Country (Brisbane City and Ipswich), located within the Brisbane metropolitan region in South East Queensland of Australia. During this research, it was concluded that, in both Quandamooka Country and Jagera Country, the respective Owners are operating within a sphere of increasingly complex challenges that impact upon their ability to conserve and have recognized the values of their obligations to Country care in planning. Common themes occurring on Country identified in this research included issues relating to a neglect of care to maintain Country by planners and government officials, and interactions that prevent Traditional Owners from having their obligation of caring for Country on their terms expressed through land-use planning legislation. Political agendas of the Queensland State that influences the interactions of planners and government with Traditional Owners were also concluded to be detrimental, and to damaging trust, ongoing discussions and understandings. These insights indicate that Aboriginal communities are facing an increasing conflicting range of perceptions and comprehensions that are hindering the expression and execution of their moral responsibility embodied in their deep ecological law to care for Country in Western planning legislative obligations. It illustrates that the responsibilities given to practicing planners and government officials to care for Country under Western law are commonly not adhered to It concludes with the suggestion that for some progress to recognize an Aboriginal responsibility to Country in planning, state-Traditional Owner relations and collaboration is now needed to help transcend the legislative challenges underpinning Western planning law.

Water, weeds and autumn leaves : learning to be drier in the alpine region

Our paper explores how and what adults living and working in the Alpine region of Victoria understand and are learning about the changes to water availability, in a time when the response to water availability is subject to extensive debate and policy attention. Interviews for this study were conducted in the towns of Bright and Mount Beauty, with participants drawn from across the Alpine region. The interviews focused on what local stakeholders from the Alpine region understood about water availability in the region and how and what they had learned about living and working with climatic changes in their local area.

The findings of our study see that there was evidence of a strong understanding of the direct and indirect impact of climate change on participants' local community area. The study also sees evidence of learning through a community 'frames of reference' as outlined by Berkhout, Hertin and Dann et al.

Lichen flora of the Mount Donna Buang Scenic Reserve, Victoria

This report investigated the lichen flora of the Mt Donna Buang Scenic Reserve in Victoria, There were several aims: to describe the lichens of the region, to produce a pictorial key enabling field identification and to determine any distribution patterns. A floristic survey covering approximately 50 square km was undertaken to determine lichen diversity of the region generally. Lichens were sampled along roads, tracks, walking trails and in sections of bush, taking into account forest type and, particularly, areas that were lichen rich. Seventy-five lichen species in 43 genera and 27 families were identified and described from the region. An unknown, species H, also was described. Of the 76 lichen species, 22 were crastose and the remainder macrolichens. The best represented families were: Cladoniaceae (8 species), Hypogymniaceae (6), Lobariaceae (7), Lecideaceae (6), Pannariaceae (6) and Parmeliaccae (6). This study described 12 species (17%) which previously were not known for Victoria and which are a first record for the state. These include: Cladonia sarmentosa (J.D. Hook & Taylor) Dodge, Graphis librata Knight, Parmelinopsis neodamaziana (Elix & Johnston) Elix & Hale, Pertusaria novaezelandiae Szatala, Placopsis pardlina f. microphylla Lamb, Porina leptalea AX. Sm., Pseudocyphellaria ardesiaca Galloway, Trapeliopsis congregant (Zahlbr.) Brako, Menegazzia myriotrema (Mull. Arg.) P. James, Bunodophoron scrobiculatum (Church. Bab,) Wedin, Parmelia testacea Stirton and Menegazzia purpurascens S. Louwhoff sp. nov.. The last eight species are new to the mainland and, apart from Menegazzia purpurascens, previously were known only from Tasmania. Five main elements of distribution were identified for the lichen flora of the Mt Donna Buang Scenic Reserve: cosmopolitan, austral/australasian, paleotropical, pantropical and western pacific. The majority of species (68%) had austral/australasian distributions, eleven (16%) were endemic to Australia and nine (13%) occurred only in Tasmania , Victoria and New Zealand. A pictorial, dichotomous key was constructed for the lichen flora of the Mt Donna Buang Scenic Reserve. Previously, keys to the lichen flora of Tasmanian rainforests were suggested as appropriate to similar areas in Victoria, however, the Victorian forests include a significant sclerophyll element The key presented is specific for the study site but is appropriate to similar regions in Victoria and has been tested in a number of these areas. The key was designed to be ‘user-friendly’ so that the experienced and inexperienced alike are able to use it. A more detailed investigation of the lichen flora of the Mt Donna Buang Scenic Reserve was carried out in order to determine distribution. A total of 50 quadrats, each 20m x 20m in size, were sampled. Within each, the dominant vegetation type was determined and individuals were identified and location noted. The cover abundance of each lichen species on each individual tree was estimated using a modified Braun-Blanquet scale. A total of 710 trees, representing 13 different species, were examined. Nothofagus cunninghamii (Hook.) Oerst, Eucalyptus regnans R Mull., Acacia dealbata Link, A. melanoxylon R. Br., Hedycarya angustifolia A. Cunn. and Atherosperma moschatum Labill. were the six most common tree species encountered at the study site. Nothofagus cunninghamii supported the greatest lichen diversity (39 species), although most species occurred on less than 10% of the trees. The majority of lichens occurring on N. cunninghamii A. melanoxylon, A. dealbata and H. angustifolia were foliose or crustose, those on Ł. regnans fruticose and foliose and those on A moschatum crustose. Bunodophoron australe was the only lichen species at the study site to occur on one host, Nothofagus cunninghamiL Many occurred on a number of different hosts, but were most common on one particular tree species. The distribution of lichens at the study site was analysed with a rnultivariate statistical package (PATN) which dealt with ‘pattern analysis’. The program ‘SSH’ in PATN which uses the Bray-Curtis ordination technique, was used to create scatterplots displaying the degree of dissimilarity between quadrats in terms of presence/absence of lichen species. The program ‘TWAY’ in PATN was used to construct a two way table to display which lichen species occurred in each vegetation type. The pattern analysis revealed that the lichens of the Mt Donna Buang Scenic Reserve were not restricted to any particular forest type, but particular lichens, or groups of lichens, tended to predominate in certain vegetation communities. This concurs with work done by others in Tasmanian forests. Quadrats which were situated in cool temperate rainforest were grouped more closely with each other than with quadrats in other vegetation types. These also supported the greatest number of lichen species. This was not surprising since N. cunninghamii the dominant tree species in cool temperate rainforest, supported the greatest lichen diversity.

Ordovician nautiloid fossils of Xainza region, Tibet

The Taerma bridge-Zhakang in the Xainza area is the second spot of Ordovician in northern Tibet based on the discovery of some reliable fossils. The strata contain a large amount of fossils of many taxa, which developed well enough to attain reliable support for era and distinctive boundary. It is the best spot for the fossil study of the Ordovician in the northern Tibet up to now and provides important clues to the classification and correlation of the Ordovician and to the paleogeography distribution as well as to the tectonic evolution of the northern Tibet. 29 species of Nautiloid fossils, which belong to 3 orders, 8 families and 15 genera, have been identified. Among them,3 genera and 9 species are new. Here only one new genus Eneoceras gen. nov. and six new species are described in detail as example. Other two new genera Taremaocera's and Variabioceras will be described in other papers.Genus Eneoceras gen.nov.Diagnosis:The new genus Eneoceras gen. nov. is characterized by the features as “Conch orthoconic, medium in size. The surface is decorated with annulus which array in a distance as the septa. Conch enlarging slowly. Compressed laterally. Circular in cross section. Siphuncle small, situated central from ventral in position. Spetal neck subcyrtochoanitic. Slightly expanded in connecting rings. Siphuncle appears as a string of beads with thin parietal deposits in it. Medium in spetal density. Thin epithecal and hypothecal deposits developed in cameras

Darumbal voyaging: intensifying use of central Queensland's Shoalwater Bay islands over the past 5000 years

Island archipelagos of the tropical coast of central Queensland include the most distant offshore islands used by Aboriginal Australians. Excavations on Collins, Otterbourne and High Peak Islands, located up to 40 km from the mainland, reveal evidence of offshore voyaging and marine specialisation in the Shoalwater Bay region for at least 5200 years. A time lag of up to 3000 years between island formation and systematic island use may reflect delayed development of key marine resources. Expansion of island use commencing around 3000–3500 years ago is linked to population increases sustained by synchronous increases in marine resources. Occupational hiatuses variously between 1000 and 3000 years ago are associated with increased ENSO activity. Intensified island use within the past 1000 years is primarily a social phenomenon associated with continuing demographic pressures and the development of more coastally and marine-focused mainland groups, with settlement patterns increasingly encompassing adjacent islands. The viability of risky offshore canoe voyaging was underwritten by two key high-return subsistence pursuits – hunting green turtles and collecting turtle eggs. In addition to subsistence and quartz quarrying, a key motivation for island visitation may have been socially restricted (e.g. ceremonial) practices.

Prospects of renewable energy in semi-arid region

Continuous usage of fossil fuels and other conventional resources to meet the growing demand has resulted in in-creased energy crisis and greenhouse gas emissions. Hence, it is essential to use renewable energy sources for more reliable, effective, sustainable and pollution free transmission and distribution networks. Therefore, to facilitate large-scale integration of renewable energy in particular wind and solar photovoltaic (PV) energy, this paper presents the feasibility analysis for semi-arid climate and finds the most suitable places in North East region of Victoria for re-newable energy generation. For economic and environmental analysis, Hybrid Optimization Model for Electric Re-newables (HOMER) has used to investigate the prospects of wind and solar energy considering the Net Present Cost (NPC), Cost of Energy (COE) and Renewable fraction (RF). Six locations are selected from North East region of Victo-ria and simulations are performed. From the feasibility analysis, it can be concluded that Mount Hotham is one of the most suitable locations for wind energy generation while Wangaratta is the most suitable location for solar energy generation. Mount Hotham is also the best suitable locations in North East region for hybrid power systems i.e., com-bination of both wind and solar energy generation.
