The leopard’s (Panthera pardus) broad geographic range, remarkable adaptability, and secretive nature have contributed to a misconception that this species might not be severely threatened across its range. We find that not only are several subspecies and regional populations critically endangered but also the overall range loss is greater than the average for terrestrial large carnivores. To assess the leopard’s status, we compile 6,000 records at 2,500 locations from over 1,300 sources on its historic (post 1750) and current distribution. We map the species across Africa and Asia, delineating areas where the species is confirmed present, is possibly present, is possibly extinct or is almost certainly extinct. The leopard now occupies 25–37% of its historic range, but this obscures important differences between subspecies. Of the nine recognized subspecies, three (P. p. pardus, fusca, and saxicolor) account for 97% of the leopard’s extant range while another three (P. p. orientalis, nimr, and japonensis) have each lost as much as 98% of their historic range. Isolation, small patch sizes, and few remaining patches further threaten the six subspecies that each have less than 100,000 km2 of extant range. Approximately 17% of extant leopard range is protected, although some endangered subspecies have far less. We found that while leopard research was increasing, research effort was primarily on the subspecies with the most remaining range whereas subspecies that are most in need of urgent attention were neglected.
Marine sediment cores were obtained from in front of the Muller Ice Shelfin Lallemand Fjord, Antarctic Peninsula in the austral summer of 199&91. Sedimentological and geochemical data from these cores document a warm period that preceded the advance of the Miiller Ice Shelf into Lallemand Fjord. The advance of the ice shelf is inferred from a reduction in the total organiccarboncontent and an increase in well-sorted, aeolian, sand in cores proximal to the present calving line. This sedimentological change is paralleled by a change in the foraminifera1 assemblages within the cores. Advance of the ice shelf is indicated by a shift from assemblages dominated by calcareous benthic and planktonic forms to those dominated by agglutinated forms. A I4C chronology for the cores indicates that the advance of the Miiller Ice Shelf took place c. 400 years ago, coincident with glacier advances in other high southern latitude sites during the onset of the Little Ice Age. Ice core evidence, however, documents this period as one of warmer temperatures for the Antarctic Peninsula. We suggest that the ice shelf advance was linked to the exclusion of circumpolar deep water from the fjord. This contributed to increased mass balance of the ice shelf system by preventing the rapid undermelt that is today associated with warm circumpolar deep water within the fjord. We also document the recent retreat of the calving line of the Miiller Ice Shelf that is apparently in response to a recent (four decade long) warming trend along the western side of the Antarctic Peninsula.
Much of the hype associated with the impact of electronic business is associated with the business to business (B2B) model. Analysts believe that enormous cost savings and efficiencies can be achieved through the utilisation of e‐procurement, a component of the B2B model. The role of procurement and the emerging use of large information systems to conduct e‐procurement is analysed and presented with the results of a survey of 38 major Australian organisations. The current direct and indirect procurement practices of the sample organisations will be analysed together with an analysis of the eprocurement drivers and barriers. The main results show that direct procurement is heavily dependant upon traditional practices whilst indirect procurement is more likely to use “e” practices. Small‐medium organisations are more nimble at adopting e‐procurement practices. Technical issues dominate e‐procurement barriers, with cost factors dominating e‐procurement drivers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
