2009 Introduction The State of the Region report describes the natural resources of Kangaroo Island; summarises their condition and the threats to those resources; and outlines the socioeconomic values of the resources. This information is critical in setting the strategic direction for natural resources management on Kangaroo Island for the next 10 years. The report summarises natural resources information under the themes: soils and landscapes water resources native biota terrestrial ecosystems aquatic ecosystems coastal, estuarine and marine ecosystems. The State of the Region report is intended to provide sufficient information to: enable someone with no prior knowledge to gain a overview understanding of the Island’s natural resources and natural resources issues identify key issues

  • The Meeting of Matthew Flinders and Nicolas Baudin
    A Cordial Encounter? 53 A Cordial Encounter? The Meeting of Matthew Flinders and Nicolas Baudin (8-9 April, 1802) Jean Fornasiero and John West-Sooby1 The famous encounter between Nicolas Baudin and Matthew Flinders in the waters off Australia’s previously uncharted south coast has now entered the nation’s folklore. At a time when their respective countries were locked in conflict at home and competing for strategic advantage on the world stage, the two captains were able to set aside national rivalries and personal disappointments in order to greet one another with courtesy and mutual respect. Their meeting is thus portrayed as symbolic of the triumph of international co-operation over the troubled geopolitics of the day. What united the two expeditions—the quest for knowledge in the spirit of the Enlightenment—proved to be stronger than what divided them. This enduring—and endearing—image of the encounter between Baudin and Flinders is certainly well supported by the facts as we know them. The two captains did indeed conduct themselves on that occasion in an exemplary manner, readily exchanging information about their respective discoveries and advising one another about the navigational hazards they should avoid or about safe anchorages where water and other supplies could be obtained. Furthermore, the civility of their meeting points to a strong degree of mutual respect, and perhaps also to a recognition of their shared experience as navigators whom fate had thrown together on the lonely and treacherous shores of the “unknown coast” of Australia. And yet, as appealing as it may be, this increasingly idealized image of the encounter runs the risk of masking some of its subtleties and complexities.

  • The Evolution Dynamics of the Strigiformes in the Mediterranean Islands with the Description of Aegolius Martae N. Sp
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Institutional Research Information System University of Turin ARTICLE IN PRESS Quaternary International 182 (2008) 80–89 The evolution dynamics of the Strigiformes in the Mediterranean islands with the description of Aegolius martae n. sp. (Aves, Strigidae) Ã Marco Pavia Dipartimento di Scienze della Terra, Museo di Geologia e Paleontologia, Via Valperga Caluso 35, I-10125 Torino, Italy Available online 14 June 2007 Abstract Living and fossil owls (Aves, Strigiformes) constitute an important group for understanding the evolutionary dynamics of birds in island environments. After their different trends in island evolution, the Strigiformes can be seen as a representative of insular adaptations of birds as a whole. In fact they respond quickly to isolation with deep changes in body size, including dwarfism and gigantism, and allometric variations, such as reduction of wings, lengthening of hindlimbs and strengthening of digits and claws. The only exception is the loss of the ability to fly, which has never been recorded in Strigiformes. In this paper I report on all the endemic owls found in Mediterranean Islands, both living and fossil, in order to emphasize trends in insular evolution and the relationships between the different species sharing a certain island. The description of Aegolius martae n. sp. completes the guild of endemic Strigiformes of the early Middle Pleistocene of Sicily and allows to use Sicily as the best example of a biogeographical island type with intermediate characteristics between the oceanic and the continental ones, with the presence of some non-flying mammals, but the lack of terrestrial carnivores.
