Diverse Range

One of the main objectives of pasture management is to meet the annual feed demand of stock by manipulating the annual feed supply from pasture. This challenge is probably greatest for high country runholders because long cold winters and often dry summers severely disrupt the continuity of pasture growth and create a mismatch between supply and demand. Within each high country run there is generally a diverse range of landscapes environments whose integration with planning, and an appropriate choice of pasture species, and selective management, can help overcome this mismatch.

Managing rangeland enterprises requires balancing socio-economic goals within a production environment characterised by ecological complexity and large climatic variability. Trafalgar Station in north-east Queensland, has been trying to maintain this balance over a period of 80 years and three generations of the one family. This paper explores how management on Trafalgar Station has gone through four evolutionary phases and examines the advantages and disadvantages of each of these stages of development. The first 50 years of management was a technologically constrained era of low stock numbers and poor productivity but there were few resource management problems. Next followed a 20 year period of production maximisation which was made possible by improved cattle genetics and nutritional technologies. With drought feeding occurring more frequently and loss of perennial grasses and soil becoming more evident, there came the realisation that this high stocking strategy was unsustainable. The management of Trafalgar then embarked on a new philosophy based on conservative stocking (similar to historical levels) and increased emphasis on herd, pasture and financial management. This new management philosophy required a transitional phase where stock numbers. and income, were very low to allow pasture condition to improve. Current herd management focuses on maintaining quality rather than quantity, strategic use of supplements for production, and developing a diverse range of markets for sale cattle. Conservative stock numbers have increased opportunities in pasture management with 15 to 20% of the property now annually rested from grazing. Fire has been reintroduced to restrict "thickening" of native woody plants and to control exotic woody weeds. Together with long-term financial planning, these improvements in management are reducing economic risk. The perceived benefits of the current management philosophy are supported by simulation modelling studies of pasture and animal production and analyses of property economics.

Achieving multi-million-hectare commitments from countries around the world to restore degraded lands in resilient and sustainable ways requires, among other things, huge volumes of tree planting material. Seed systems encompassing all forest reproductive material (e.g., seeds, cuttings, stakes, and wildings), are key to ensuring that sufficient planting material with a diverse range of suitable species, adapted to local conditions and capable of persisting under a changing climate, is available for restoration projects. The ideal structure of a seed system integrates five components: seed selection and innovation, seed harvesting and production, market access, supply and demand, quality control, and an enabling environment. We propose 15 indicators to evaluate these key components and trial them by assessing national seed systems in 7 Latin American countries. We conclude that the indicators enable a straightforward assessment of the strengths and weaknesses of national seed systems, thus assisting governments to identify key areas for improvement and opportunities for horizontal learning.

Beef Market

During 1996 and 1997, a survey examined the business activities of 375 selected northern Australian beef producers during the 1991 and 1992 to 1995 and 1996 financial years. The producers represented a broad cross-section of the northern beef industry in terms of geographical location, size of enterprise and herd, and ownership structures. The survey examined the enterprise structures and herd productivity of the participating properties. A diverse range of production activities were carried out with breeding and finishing, of which breeding stores and live cattle export being the most common activities. About 50% of the survey properties were run in conjunction with another property, both of which tended to be located in the same survey region. The additional properties served various purposes, depending on their location. There was evidence of specialist roles for the additional properties. The purchase of store cattle tended to be an opportunistic activity with younger cattle (<2 years old) being most preferred. Survey properties tended to target a range of markets; Northern Territory and northern Western Australian properties being the most likely to target a single market (live export). Aspiring to supply the slaughter markets was of greatest interest to Queensland beef producers. Aspiring to supply the USA manufacturing beef market was lowest where interest in live export was greatest. During the survey period, the USA manufacturing beef market, store and live cattle export markets were important outlets for cattle. Many herd and pasture-related improvements were planned to boost profitability in the 5 years post-survey (1997–2002). Increasing turn-off weight and branding rate, and decreasing turn-off age were of greatest interest to surveyed beef producers. Pasture improvement and improving pasture management also rated highly. The survey data indicated that the female genotype of the northern Australian herd had changed significantly over a 10- and 30-year period, with Bos indicus, Bos indicus cross and Taurindicus breeds being the most commonly reported breeds. The bull breeds present in regional herds suggest crossbreeding is occurring in conjunction with pure breeding. Most herds had more than 1 bull and female breed. Regional patterns were also found to exist for female and bull breeds with Bos indicus being common in herds in the northern parts of the survey area and Taurindicus breeds popular in southern herds. The results of this survey are discussed in relation to future developments in the northern Australian beef industry.

Micro Organisms

Amyloids are insoluble fibrillar protein deposits with an underlying cross-β structure initially discovered in the context of human diseases. However, it is now clear that the same fibrillar structure is used by many organisms, from bacteria to humans, in order to achieve a diverse range of biological functions. These functions include structure and protection (e.g. curli and chorion proteins, and insect and spider silk proteins), aiding interface transitions and cell–cell recognition (e.g. chaplins, rodlins and hydrophobins), protein control and storage (e.g. Microcin E492, modulins and PMEL), and epigenetic inheritance and memory [e.g. Sup35, Ure2p, HET-s and CPEB (cytoplasmic polyadenylation element-binding protein)]. As more examples of functional amyloid come to light, the list of roles associated with functional amyloids has continued to expand. More recently, amyloids have also been implicated in signal transduction [e.g. RIP1/RIP3 (receptor-interacting protein)] and perhaps in host defence [e.g. aDrs (anionic dermaseptin) peptide]. The present chapter discusses in detail functional amyloids that are used in Nature by micro-organisms, non-mammalian animals and mammals, including the biological roles that they play, their molecular composition and how they assemble, as well as the coping strategies that organisms have evolved to avoid the potential toxicity of functional amyloid.

The paper provides a justification of the laws of supply and demand using the concept of a marginal firm (technology) for the case of perfect competition.The ideological factor of excessive attention to the analysis of marginal parameters at the firm level in the introductory economics courses is discussed. The author connects these issues to the ideas of J. B. Clark and gives an alternative treatment of exploitation.
