The need for public investment to address loss of biodiversity in agricultural landscapes is well recognised, yet there is little analysis of the likely benefits of land‐use change for regional biodiversity or the cost effectiveness of different investment options. We estimated benefits for biodiversity and cost effectiveness of different investment scenarios over 50 years for a farming area in south‐eastern Australia. Declines in biodiversity were predicted under status quo land use. Implementing actions in the investment scenarios improved biodiversity status only slightly, compared with status quo land use. Future biodiversity status differed little between biodiversity‐focused investment and salinity‐focused investment. Biodiversity status equalled or exceeded current status only for investment scenarios with much more extensive revegetation than in catchment targets. Cost effectiveness of biodiversity improvement varied greatly between investment strategies. Biodiversity improvement was more cost effective when investment to meet catchment targets was focused on revegetation for salinity management rather than on high conservation value areas, because of lower opportunity costs for salinity management. With enhanced investment, the cost effectiveness of biodiversity improvement was greater when actions were in high conservation areas. Although improvements in biodiversity were small under the changed farming system scenarios, their cost effectiveness was higher than the other investment scenarios. Regional scale improvements in biodiversity in farming areas will require increased stewardship payments or other economic incentives for landholders. 相似文献

During the development project at 20 Fenchurch Street in the City of London, archaeological excavations were undertaken adjacent to Rood Lane. This uncovered part of a 16th- to mid 17th-century brick built cellar which had collapsed sealing in situ pottery, glass, clay tobacco pipes and a stove tile, an event interpreted as the result of the Great Fire of London in 1666. The composition of this artefact assemblage suggests it was derived from a property used to providing large-scale entertainment, with a high proportion of the material associated with drinking. This article situates this group within the context of other similarly dated victualling establishments from the City of London. 相似文献

Of all the long bones in the human skeleton, it is the clavicle which displays the longest period of growth-related activity, rendering it particularly useful for the estimation of age at death in the earlier years. However, because of the universal paucity of documented juvenile remains, most previous studies have, by necessity, not only been based on material of estimated age at death but also restricted to a narrow age range. The aim of the present study was to chart developmental age-related change in the clavicle across its full growth range using juvenile and young adult material of documented age at death. Maximum diaphysial length was recorded for prepubertal individuals and a grading of the progressive alterations in medial epiphysial morphology was recorded for post-pubertal specimens. In this way, age changes in the clavicle were examined across its developmental maturity continuum. 相似文献
