Neves, J.P., Anelli, L.E., Pagani, M.A. & Simões, M.G., 2014. Late Palaeozoic South American pectinids revised: biostratigraphical and palaeogeographical implications. Alcheringa 38 ISSN 0311-5518.A revision of the late Palaeozoic South American pectinid Heteropecten multiscalptus (Thomas) and the establishment of Heteropecten paranaensis sp. nov. have important implications for the relationship between faunal realms within South America. Late Palaeozoic bivalve faunas occur in three distinct realms in South America: a Central Gondwanic Realm with endemic taxa showing affinities to Australia, New Zealand, South Africa and Namibia, a cold Perigondwanic Realm, and a warm Extragondwanic Realm with tethyan-like affinities similar to faunas of the American Midcontinent. In South America, faunas east of the southern Andes belong to the first two realms and previous interpretations of bivalve faunas suggested biocorrelations with those of the Extragondwanic Realm because they shared the taxon Heteropecten multiscalptus (Thomas). A revision of the Peruvian and Brazilian material does not confirm this. Instead, a re-analysis suggests that two species are present, rather than one: Heteropecten multiscalptus in the Cerro Prieto Formation, Amotape Mountains (Peru; Extragondwanic Realm), and Heteropecten paranaensis sp. nov. in the upper part of the Itararé Group, Paraná Basin (Brazil; Central Gondwanic Realm). Thus, the correlation between the late Palaeozoic faunas of the Central Gondwanic and Extragondwanic Realms in South America can no longer be supported. Heteropecten paranaensis sp. nov. lived in a siliciclastic-dominated, cold, epeiric sea of Brazil and Argentina, and is morphologically similar to some Australian species, whereas the Peruvian H. multiscalptus thrived in the warm seas of the Extragondwanic Realm.Jacqueline P.

Environmental opposition groups have often formed in rural communities as a response to sweeping environmental regulations. They do not match the stereotypes of nongovernmental organizations funded by extractive resource industries, but have a solid grass-roots membership that is stalling, if not altogether thwarting, the momentum of the environmental movement. 相似文献

Paleoclimatic data from the tropical Pacific islands are compared to archaeological evidence for fortification construction in the Holocene. The results suggest that in some regions, people constructed more fortifications during periods that match the chronology for the Little Ice Age (AD 1450–1850) in the Northern Hemisphere. Periods of storminess and drought associated with the El Niño Southern Oscillation have less temporal correlation with the emergence of fortifications in the Pacific, but significant spatial correlation with the most severe conditions associated with this cycle. These temporal and spatial correlations require additional study to investigate possible causal relationships. 相似文献

Recent multidisciplinary investigations document an independent emergence of agriculture at Kuk Swamp in the highlands of Papua New Guinea. In this paper we report preliminary usewear analysis and details of prehistoric use of stone tools for processing starchy food and other plants at Kuk Swamp. Morphological diagnostics for starch granules are reported for two potentially significant economic species, taro (Colocasia esculenta) and yam (Dioscorea sp.), following comparisons between prehistoric and botanical reference specimens. Usewear and residue analyses of starch granules indicate that both these species were processed on the wetland margin during the early and mid Holocene. We argue that processing of taro and yam commences by at least 10,200 calibrated years before present (cal BP), although the taro and yam starch granules do not permit us to distinguish between wild or cultivated forms. From at least 6950 to 6440 cal BP the processing of taro, yam and other plants indicates that they are likely to have been integrated into cultivation practices on the wetland edge. 相似文献

The focus of this contribution is the Hong Kong Special Administrative Region (HKSAR) of China, and more particularly the processes of environmental reform in the region. The authors discuss developments in environmental policy over the past three decades and explore the utility of Ecological Modernization Theory as a basis for future environmental reform at the local level and as a mechanism for tackling broader regional environmental concerns. The contribution also explores linkages between technology policy and the environment in Hong Kong, arguing that while the SAR possesses certain competitive advantages, greater attention must be given to fostering and facilitating technological innovation in the environmental sector. 相似文献

This article explores the impact of globalization in the context of human rights enforcement within the European Union. It argues that despite the growing impact of transnational forces and supranational institutions, national mechanisms are still crucial in enforcing international obligations, so that states remain critical players rather than diminishing entities. The article considers the development of human rights as a fundamental norm within the European Union, and explores the relevance of this norm for third country (i.e. non-European) nationals. It argues that restrictionist policies designed to curtail immigration and exclude asylum seekers override international human rights obligations voluntarily entered into by the European member states. Even the concept of European Union citizenship, designed in part to address the rights deficit within Europe, has not so far created a base of fundamental rights capable of trumping state interests, but rather functions primarily as an exclusionary concept directed against non-Europeans. 相似文献
