Northern Beef Research Update Conference 2013 Organising Committee: Kiri Broad, Ed Charmley, Michael Lyons, Janine King, Jackie Kyte, Tim McGrath, Michael Quirk, Ian Watson. ii FOREWORD It is again my great pleasure to introduce these proceedings for the 2013 Northern Beef Research Update Conference (NBRUC). In so doing I’m acutely aware just how precious are each of the contributions made to the improvement of the northern Australian beef industry. These contributions are made all the more precious by the continued decline in R,D and E capability amongst our leading provider organisations and the gradual ageing of our R,D and E and producer populations. The North Australia Beef Research Council continues to be a force for collaboration and change to enable the greatest benefit to be achieved from our collective effort. This NBRUC is an opportunity to share our ideas and research outcomes and to celebrate our shared vision and passion for the northern beef industry. May it also be an affirmation to those who work tirelessly for the industry, and in the pursuit of progress. I certainly wish to take the opportunity to thank you all for your contribution, not only to this conference, but to a better tomorrow. My thanks to the committee which has made this conference happen under the Chairmanship of Michael Lyons. It remains for us to hope that the results presented at and derived from this conference will make a significant positive impact on how the industry operates in these most trying of times, and show producers struggling in those times that much has been and will continue to be done with their best interests at heart. Once again, my congratulations and thanks to all concerned.

    Investigation of Mitochondrial-Derived Plastome Sequences in the Paspalum Lineage (Panicoideae; Poaceae) Sean V

    Burke et al. BMC Plant Biology (2018) 18:152 https://doi.org/10.1186/s12870-018-1379-1 RESEARCH ARTICLE Open Access Investigation of mitochondrial-derived plastome sequences in the Paspalum lineage (Panicoideae; Poaceae) Sean V. Burke1* , Mark C. Ungerer2 and Melvin R. Duvall1 Abstract Background: The grass family (Poaceae), ca. 12,075 species, is a focal point of many recent studies that aim to use complete plastomes to reveal and strengthen relationships within the family. The use of Next Generation Sequencing technology has revealed intricate details in many Poaceae plastomes; specifically the trnI - trnL intergenic spacer region. This study investigates this region and the putative mitochondrial inserts within it in complete plastomes of Paspalum and other Poaceae. Results: Nine newly sequenced plastomes, seven of which contain an insert within the trnI - trnL intergenic spacer, were combined into plastome phylogenomic and divergence date analyses with 52 other species. A robust Paspalum topology was recovered, originating at 10.6 Ma, with the insert arising at 8.7 Ma. The alignment of the insert across Paspalum reveals 21 subregions with pairwise homology in 19. In an analysis of emergent self- organizing maps of tetranucleotide frequencies, the Paspalum insert grouped with mitochondrial DNA. Conclusions: A hypothetical ancestral insert, 17,685 bp in size, was found in the trnI - trnL intergenic spacer for the Paspalum lineage. A different insert, 2808 bp, was found in the same region for Paraneurachne muelleri. Seven different intrastrand deletion events were found within the Paspalum lineage, suggesting selective pressures to remove large portions of noncoding DNA. Finally, a tetranucleotide frequency analysis was used to determine that the origin of the insert in the Paspalum lineage is mitochondrial DNA.

    Managing Bird Damage Managing Bird Managing Bird Damage Bird damage is a significant problem in Australia with total to Fruit and Other Horticultural Crops damage to horticultural production estimated at nearly $300 million annually. Over 60 bird species are known to damage horticultural crops. These species possess marked differences in feeding strategies and movement patterns which influence the nature, timing and severity of the damage they cause. Reducing bird damage is difficult because of the to Fruit and Other Horticultural Crops Fruit and Other Horticultural to unpredictability of damage from year to year and a lack of information about the cost-effectiveness of commonly used management practices. Growers therefore need information on how to better predict patterns of bird movement and abundance, and simple techniques to estimate the extent of damage to guide future management investment. This book promotes the adoption of a more strategic approach to bird management including use of better techniques to reduce damage and increased cooperation between neighbours.

    Lose the Plot: Cost-Effective Survey of the Peak Range, Central Queensland

    Lose the plot: cost-effective survey of the Peak Range, central Queensland. Don W. Butlera and Rod J. Fensham Queensland Herbarium, Environmental Protection Agency, Mt Coot-tha Botanic Gardens, Mt Coot-tha Road, Toowong, QLD, 4066 AUSTRALIA. aCorresponding author, email: [email protected] Abstract: The Peak Range (22˚ 28’ S; 147˚ 53’ E) is an archipelago of rocky peaks set in grassy basalt rolling-plains, east of Clermont in central Queensland. This report describes the flora and vegetation based on surveys of 26 peaks. The survey recorded all plant species encountered on traverses of distinct habitat zones, which included the ‘matrix’ adjacent to each peak. The method involved effort comparable to a general flora survey but provided sufficient information to also describe floristic association among peaks, broad habitat types, and contrast vegetation on the peaks with the surrounding landscape matrix. The flora of the Peak Range includes at least 507 native vascular plant species, representing 84 plant families. Exotic species are relatively few, with 36 species recorded, but can be quite prominent in some situations. The most abundant exotic plants are the grass Melinis repens and the forb Bidens bipinnata. Plant distribution patterns among peaks suggest three primary groups related to position within the range and geology. The Peak Range makes a substantial contribution to the botanical diversity of its region and harbours several endemic plants among a flora clearly distinct from that of the surrounding terrain. The distinctiveness of the range’s flora is due to two habitat components: dry rainforest patches reliant upon fire protection afforded by cliffs and scree, and; rocky summits and hillsides supporting xeric shrublands.

    Purnululu National Park

    World Heritage Scanned Nomination File Name: 1094.pdf UNESCO Region: ASIA AND THE PACIFIC __________________________________________________________________________________________________ SITE NAME: Purnululu National Park DATE OF INSCRIPTION: 5th July 2003 STATE PARTY: AUSTRALIA CRITERIA: N (i)(iii) DECISION OF THE WORLD HERITAGE COMMITTEE: Excerpt from the Report of the 27th Session of the World Heritage Committee Criterion (i): Earth’s history and geological features The claim to outstanding universal geological value is made for the Bungle Bungle Range. The Bungle Bungles are, by far, the most outstanding example of cone karst in sandstones anywhere in the world and owe their existence and uniqueness to several interacting geological, biological, erosional and climatic phenomena. The sandstone karst of PNP is of great scientific importance in demonstrating so clearly the process of cone karst formation on sandstone - a phenomenon recognised by geomorphologists only over the past 25 years and still incompletely understood, despite recently renewed interest and research. The Bungle Bungle Ranges of PNP also display to an exceptional degree evidence of geomorphic processes of dissolution, weathering and erosion in the evolution of landforms under a savannah climatic regime within an ancient, stable sedimentary landscape. IUCN considers that the nominated site meets this criterion. Criterion (iii): Superlative natural phenomena or natural beauty and aesthetic importance Although PNP has been widely known in Australia only during the past 20 years and it remains relatively inaccessible, it has become recognised internationally for its exceptional natural beauty. The prime scenic attraction is the extraordinary array of banded, beehive-shaped cone towers comprising the Bungle Bungle Range. These have become emblematic of the park and are internationally renowned among Australia’s natural attractions.

    CYTOLOGICAL STUDIES IN THE GRAMINEIE D. N. SINGH and M. B. E. GODWARD Botany Department, Queen Mary College, London Received5.iv.60 THERE are still many tropical and warm temperate grasses, particularly those of Asia, Australia and Africa whose nuclear cytology has not been fully investigated and whose taxonomy is still difficult or has been subject to recent investigation. A cytological study of some of these has been begun. The investigation of special problems which have been suggested by Mr W. D. Clayton and Mr J. K. O'Byrne of the Herbarium, Kew, and Mr W. H. Foster, Samaru, Nigeria, will be published elsewhere. Root-tips of seedlings and young anthers have been used for chromosome counts in 53 species belonging to 25 genera of the family Gramine (table i).For two genera, Cal)ptochloa of Queensland, Australia and Tetrapogon of Kenya, and 29 species the counts are new. Others differ from those found by previous workers (see Darlington and Wylie, 1955). NOTESON TABLE i.ANDROPOGON: Species Hybrids Material of Andropogon gqyanus Kunth, showing morphological differences has been collected by Mr W. H. Foster from different parts of Nigeria. Morphological differences seem to be associated with polyploidy and aneuploidy. The distribution of these forms found by Mr Foster in Nigeria appears to be such that the diploid A. gajvanus Kunth (2n =20)are in the north of the country, and diploid A. tectorum Schumach and Thonn in the south. The tetraploids (2n =40)and the aneuploids (2n =35to 43) are between them. These latter are presumably hybrids. These plants are being grown on for further studies and further collections are being made in Nigeria.
