Two spring-fed swamp deposits in northwestern Tasmania which contain non-marine ostracods are characterized by an alternation of marl, peaty marl and peaty layers: the Pulbeena Swamp deposit (4.80 m thick) was formed over approximately the last 80,000 years, and Mowbray Swamp (2 m thick) over about the last 110,000 years. Fifteen ostracod species have been recovered from 179 samples: three are new, three are in open nomenclature and the others have living representatives. The ostracod data compared with pollen curves for both sites demonstrate, for most levels, a good correlation between the abundance of ostracods and that of Cyperaceae and Potamogeton-Triglochin pollen. This implies that ostracods can be successfully used as indicators of different water regimes for spring-fed swamps. Comparison of the ostracod fauna from the two Tasmanian sites is also made with that of other known Australian and New Zealand swamp deposits. 相似文献
Mays, C. & Cantrill, D.J., January 2018. Protodammara reimatamoriori, a new species of conifer (Cupressaceae) from the Upper Cretaceous Tupuangi Formation, Chatham Islands, Zealandia. Alcheringa XXX, X–X. ISSN 0311-5518.
Isolated conifer female reproductive structures are common fossil elements from Cenomanian (ca 99–94 Ma) charcoal- and resin-rich beds of the Tupuangi Formation, Chatham Islands, southwest Pacific Ocean. Recent findings have proposed that these are the oldest fossil evidence of serotiny, a highly successful fire-adaptive reproductive strategy common among tree species living in fire-prone areas today. Herein, we systematically describe the external morphological and anatomical features of these fossils, by employing a combination of manual extraction and neutron tomography techniques. We propose a new species of conifer, Protodammara reimatamoriori, and a re-examination of fossil material of the Protodammara type species facilitated an emendation of the genus. Protodammara shares numerous features with extant Cunninghamia, Taiwania, Athrotaxis, and several extinct taxa of Cupressaceae, and is interpreted as an extinct lineage of the early-divergent ‘taxodioid Cupressaceae’ stem group.

AbstractA Festa do Boi is a festive celebration linked to the Catholic liturgical calendar, which is celebrated in Allariz (Galicia-Spain). This festival reappears in the 1980s and like other popular festivals, it collects traditional elements and re-builds them into a new festive ritual, more in line with the new temporal and spatial configuration of the late 20th century. They are festivals in which tradition is combined, in representation of the local community, and the tourist approach (Prats, 1997Prats, L. L. (1997). Antropología y patrimonio.Madrid: Alianza.[Google Scholar]). This event can be analysed as a spontaneous communitas (Turner, 1974aTurner, V. (1974a). Dramas, fields and metaphors.New York: Cornell University Press.[Google Scholar]), a happening between hosts and guests (Smith, 1992Smith, V. L. (1992). Anfitriones e invitados (Turismo y sociedad).Madrid: Endymion.[Google Scholar]), where the liminal space can be occupied by tourists as ‘others’ necessary for the identification of ‘ourselves’. The participation of tourists in the festive ritual is carried out from two liminal positions: an unstable state because their daily life has been broken by the movement and involvement required in the festivals with the role of equals, but different. Both actors are required for the exaltation of collective identity. The level of satisfaction of tourists with the liminal experience based on the feeling of belonging and identification with the host community and the hedonistic perception, to provide a more holistic view of the festive ritual. A self-administered on-site survey was conducted on 393 tourists attending the 700th edition of A Festa do Boi in Allariz (Spain). The results suggest that hedonism acts as a precedent for satisfaction evaluation, and satisfaction evaluation for the attendees´ future intentions. In addition, the liminal experience has a two-dimensional structure composed of the individual changes experienced and of the festive ritual. 相似文献
AbstractThe unfolding COVID-19 pandemic has closed borders, grounded planes, quarantined more than half of the world’s population, triggered anxiety en masse, and shaken global capitalism to its core. Scholars of the political ecology of disasters have sought to denaturalize so-called “natural” disasters by demonstrating their uneven consequences. Work in the political ecology of health similarly accounts for how risk of illness and disease are socio-economically mediated. While this scholarship has demonstrated the need to contextualize the unequal fallout from ecological and health disasters in ways that reveal the festering wounds of structural inequality, we know much less about how hope is cultivated in moments of crisis. The current revelatory moment of the COVID-19 pandemic offers an opportunity to find hope in the rubble through the deconstruction of framings of crisis as “error” and by homing in on the current and potential role of tourism to contribute to a more socially and environmentally just society. This reframing the pandemic as an "unnatural" disaster opens new debates at the intersection of tourism geographies and political ecologies of hope in revelatory moments of crisis. 相似文献
Water valuation represents both an opportunity and a challenge for interdisciplinary scholarly research, given that it can mobilize academic work beyond unnecessary cleavages between physical and social sciences. The article revisits the most common valuation approaches – namely, water as an economic resource, entangled in commodification strategies and embedded in cultural heritages – as important, but incomplete, considerations of the multitude of water values. While previous publications have dealt with the values held by different social groups and by the territorialized manifestation of water values, the limitations of prevailing valuation strategies are discussed here and a relational synthesis is proposed. As relevant as the examination of particular values (e.g. economic, non‐economic, religious, cultural, aesthetic values, etc.) is the realization that the valuation of water is articulated according to socionatural interdependencies and the historic‐geographical trajectories of individuals and groups. Water valuation is, therefore, premised on a relational, holistic ontology, in the sense that values are necessarily interrelated and emerge out of concrete, politicized socionatural interactions. Making use of relevant examples, it is argued that the valuation of water is ultimately a political statement that synthesizes mechanisms of cooperation and competition between individuals and social groups for the allocation, use and conservation of water. Such politicized understanding of the interconnections between water values provides a helpful entry point into the causes and consequences of water management problems. These are all profoundly geographical, but also interdisciplinary, questions, as water values reflect multiscale connections between local processes and wider relations of production, consumption and reproduction. 相似文献
The Canine Surrogacy Approach (CSA) is a form of analogy in which stable isotope information from dog remains is used as a proxy for associated human keepers. The approach has garnered increasing attention in recent years due to its capacity to provide information on human diets in contexts where human remains are limited or unavailable. CSA applications have often been conducted on an ad hoc basis and rarely has the human–dog analogy been treated systematically or cohesively. This case study aims to remedy this issue. Using a recently developed CSA interpretive framework (Guiry, 2012), we test the feasibility of using dog bone collagen stable carbon and nitrogen isotope signatures as a proxy for their human keepers among two similar marine oriented Late Archaic populations that occupied the northeastern coast of North America. After characterizing the feasibility of CSA applications in these archaeological contexts, the CSA is then used to reconstruct diet at a culturally related site at which no human remains have been recovered. 相似文献
ABSTRACTThis article shows how the ecology and nature of the Rzuchów Forest (in the Rzuchów district of the Ko?o forestry inspectorate in Greater Poland) was indirectly affected by the extermination of the Jewish population as a result of it being used to camouflage evidence of the crimes. Tracing the environmental history of commemoration in the forested part of the former death camp at Che?mno on the Ner (Che?mno nad Nerem/ Kulmhof an der Nehr) will give an indication of the ecological consequences of efforts to preserve the material traces of the camp and its natural surroundings. These efforts continued into the late 1980s. The ecology of commemoration and environmental commemoration form the two poles of this ecological continuum. It is possible to bring them closer together by furthering debates on the relationship between genocide and ecocide, while also expanding existing narratives on the Holocaust by turning to environmental aspects. This research is guided by the idea that it is necessary to rethink existing (and planned) forms of commemoration of crimes against humanity in the context of environmental ethics, with this approach leading to forms of commemoration at killing sites that give more consideration to the environment. 相似文献
