Abstract:
Crop yield in the sandy soils of the Western Australian wheatbelt is influenced strongly by the plant-available water (PAW) and strength of subsoils. The fabric of hard subsoils of fluvial and aeolian origin has been compared with that of in situ saprolite materials that also occur as subsoils in Western Australia. A fabric classification was developed and relationships between, fabric, water retention, and strength were examined. The clay matrix of hard subsoils is denser and is less porous than in saprolite. Hard subsoils contain rounded quartz grains and transported, rounded aggregates of c

Abstract:
In reality, there can be no generic definition of an “ideal soil” because a soil’s performance is influenced by the local climate, landscape characteristics, grape variety, and cultural practices and is judged in the context of a winegrower’s objectives for style of wine to be made, market potential, and profitability of the enterprise. This realization essentially acknowledges the long-established French concept of terroir: that the distinctiveness or typicity of wines produced in individual locations depends on a complex interaction of biophysical and human cultural factors, interpreted by many as meaning a wine’s sense of place. As discussed in “Soil Variability and the Concept of Terroir” in chapter 1, because of this interaction of factors that determine a particular terroir, it is not surprising that no specific relationships between one or more soil properties and wine typicity have been unequivocally demonstrated. While acknowledging this conclusion, it is still worthwhile to examine how variations in several single or combined soil properties can influence vine performance and fruit character. These properties are: • Soil depth • Soil structure and water supply • Soil strength • Soil chemistry and nutrient supply • Soil organisms Provided there are no subsoil constraints, the natural tendency of long-lived Vitis vinifera, on own roots or rootstocks, to root deeply and extensively gives it access to a potentially large store of water and nutrients. In sandy and gravely soils that are naturally low in nutrients, such as in the Médoc region of France, the Margaret River region in Western Australia, and the Wairau River plain, Marlborough region, New Zealand, the deeper the soil the better. A similar situation pertains on the deep sandy soils on granite in the Cauquenas region, Chile. However, such depth may be a disadvantage where soils are naturally fertile and rain is plentiful, as in parts of the Mornington Peninsula, King and Yarra Valley regions, Victoria, Australia, and the Willamette Valley region in Oregon (see figure 1.11, chapter 1), because vine growth is too vigorous and not in balance.

Abstract:
The biodiversity of Mediterranean-climate ecosystems is of particular interest and concern, not only because all five of these regions (the Mediterranean basin, California, central Chile, Cape Province of South Africa, western and southern parts of Australia) are among the thirty-four hotspots of species diversity in the world (Mittermeier et al. 2004), but they are also hotspots of human population density and growth (Cincotta and Engelman 2000). This relationship is not surprising because there is often a correlation between the biodiversity of natural systems and the abundance of people (Araùjo 2003; Médail and Diadema 2006) and this, inevitably, raises conservation problems. Within the larger hotspot of the Mediterranean basin as a whole, ten regional hotspots have been identified. They cover about 22 per cent of the basin’s total area and harbour about 44 per cent of Mediterranean endemic plant species (Médail and Quézel 1997, 1999), as well as a large number of rare and endemic animals (Blondel and Aronson 1999). A key feature of these Mediterranean hotspots as a whole is their extraordinarily high topographic diversity with many mountainous and insular areas. Not surprisingly this results in high endemism rates and they contain more than 10 per cent of the total plant richness (see the recent synthesis of Thompson 2005). However, of all the mediterranean-type regions in the world, the Mediterranean basin harbours the lowest percentage (c.5%) of natural vegetation considered to be in ‘pristine condition’ (Médail and Myers 2004; Chapter 7). With an average of as many as 111 people per km2, one may expect a significant decline in biological diversity in the Mediterranean basin—a region that has been managed, modified, and, in places, heavily degraded by humans for millennia (Thirgood 1981; Braudel 1986; McNeill 1992; Blondel and Aronson 1999; Chapter 9). There are two contrasting theories that consider the relationships between humans and ecosystems in the Mediterranean (Blondel 2006, 2008). The first one is the ‘Ruined Landscape or Lost Eden’ theory, first advocated by painters, poets, and historians in the sixteenth and seventeenth centuries, and later by a large number of ecologists.

Abstract:
The kava plant, Piper methysticum Forst. f., is an attractive shrub in the pepper family, Piperaceae (figure 12.1). Known by various names in tropical Pacific, such as yagona, kava, kava kava, ’awa, seka, and sakau, it is propagated vegetatively, as are most of the traditional crops in the region. Kava has been used for many centuries to produce psychoactive preparations. Its active principles, several lipidlike substances known as kavalactones, are concentrated in the rootstock and roots. These psychoactive chemicals are ingested traditionally by Pacific islanders as cold-water infusions of chewed, ground, pounded, or otherwise macerated kava stumps and roots. Mind-altering kava preparations are, or once were, imbibed in a wide range of Pacific Ocean societies. These include peoples living in some lowland areas on the large Melanesian island of New Guinea in the western Pacific to very isolated islands such as those in Polynesian Hawai’i, 7,000 kilometers to the northeast (figure 12.2). Beyond this widespread local use in the tropical Pacific, utilization of kava in parts of Europe as a plant source for medicinal preparations has a relatively lengthy history. In Europe it has been used as a sedative, tranquilizer, muscle relaxant, relief from menopausal symptoms, and treatment for urinary tract and bladder ailments (Lebot et al. 1999). Over the past decade, there has been rapidly increasing interest in kava well beyond the areas of traditional use among Pacific Islanders (figure 12.3). This includes a huge surge in the use of kava products in Europe, North America, Australia, and elsewhere. Within the past 3 to 5 years there has been widespread recognition of its potential to emerge as a mainstream herbal product. Modern cultivation and use of kava in the Pacific has significantly expanded in some traditional use areas such as Vanuatu, Fiji, Tonga, Samoa, and Pohnpei. There are also significant signs of rejuvenated interest in kava cultivation in some traditional areas of use where it had been abandoned because of depopulation, political prohibition, or zealous missionary denunciation. Increasing use and cultivation of kava on these Pacific islands has been stimulated by local consumption rates and rising demand for commercial export.

"in Kununurra; indeed, occasional seroconversions have been recorded in every month of the year. Elsewhere in the Kimberley region, seroconversions occur in most years towards the end of the wet season at all sites monitored, but the overall frequency tends to be less than that observed in Kununurra, except when flooding is extensive and widespread. Until about 1990, most seroconversions in sentinel chickens in the Pilbara region were due to infections with Kunjin virus, but over the next three years seroconversions to MVE virus showed a significant increase in incidence, suggesting that virus movement from the Kimberley region may be occurring more often. Since 1993, however, Kunjin virus activity has once again become more prevalent in the Pilbara area. Mosquito collections Continuing studies in 1976 and 1977 in the Ord River area using bait traps showed that while Culex annulirostris continued to dominate the mosquito fauna of the area, other species such as Coquillettidia xanthogaster, Mansonia uniformis and Anopheles bancroftii increased in number following stabilization of the margins of Lake Kununurra and the prolific growth of aquatic plant species (Wright 1981). Studies in the West Kimberley area in 1977 in the Derby area also found that Culex annulirostris was the dominant mosquito species (Wright et al. 1981). A major advance in mosquito trapping in the north of Western Australia was the introduction of the EVS-CO light trap in 1978, which replaced the use of bait traps after 1979. This resulted in a ninefold increase in the number of mosquitoes being collected, and a significant increase in the species diversity, although Culex annulirostris remained the dominant species (Stanley 1979). Annual mosquito collections have continued to be undertaken in the Ord River area and at other sites in the Kimberley region since 1978, particularly at the end of the wet season although also at other times if unusual environmental conditions such as cyclones or early wet season flooding have occurred. With the stabilization of Lakes Argyle and Kununurra and of the area under irrigation, the results obtained have provided a clearer association between environmental conditions, mosquito numbers and virus activity (see below). Although the mosquito density, and thus the number collected, is always relatively high in the Ord River area, heavy wet season rainfall and flooding result in a significant increase in the mosquito density. In other areas of the Kimberley, a similar pattern has emerged but the increase in the mosquito density is often more marked than in the Ord River area, and the proportion of different mosquito species tends to vary considerably. Nevertheless, regardless of the study area, Culex annulirostris dominates after widespread heavy rainfall and flooding, but if the rainfall is more localized, other floodplain breeding species such as Aedes normanensis may dominate initially (e.g. Broom et al. 1992)."
