THE MOST PERFECT EXAMPLE OF AN ALIEN ECOLOGY EVER CONSTRUCTED     

《The Professional geographer》2013,65(4):471-477

Much science-fiction literature is based upon the creation and exploration of alternative environments. Stanley G. Weinbaum's short story, “Parasite Planet,”introduces an unusual environment that may be wrong in the light of recent evidence on Venus but still stimulates the geographical imagination.  相似文献   

Forever transnational: The ambivalence of return and cross‐border activities of the Shan across the Thailand‐Myanmar border          下载免费PDF全文

Amporn Jirattikorn 《Singapore journal of tropical geography》2017,38(1):75-89

Over the past two decades, northern Thailand has experienced a massive influx of Shan ethnic nationals from Myanmar migrating to escape economic hardship and political conflicts at home. Myanmar's recent reforms raise the question of whether these migrants will return. The paper brings together the context of current changes in Myanmar with migrants' prospects of return and the impact of large‐scale migration on homeland politics. On the one hand, the paper explores the possibility that Shan migrants could remain forever transnational, for many of them will most likely never return. On the other hand, it considers the perspective of Shan elites in Myanmar on the fact a large portion of young Shan now spend their adult lives living and working in Thailand. While out‐migration of young Shan threatens the social fabric of Shan community in Myanmar, Shan ethnonationalists strive across the Myanmar border to regain loyalty among the Shan migrant population in Thailand. By examining the two aspects, this paper attempts to shed light on the impact of transnational migration on both migrants and their home country.  相似文献   

Strategies of Successful Anti-Dam Movements: Evidence from Myanmar and Thailand     

Julian Kirchherr 《社会与自然资源》2018,31(2):166-182

Scholars are rarely able to examine anti-dam movements that result in project suspensions or cancellations since these cases are rare empirically. Yet, they are central to understanding how anti-dam movements can succeed. This paper analyzes the movements against Myanmar’s Myitsone Dam and Thailand’s Kaeng Suea Ten Dam. Likely the most successful anti-dam movements in Southeast Asia in recent years, they achieved suspension over 6 and 37 years, respectively. The research is based on 60 semistructured interviews carried out over a period of 8 months. Leveraging thinking from both the constructionist and structural schools within the field of social movement studies, it is found that the framing of the Myitsone Dam as a project threatening the national cultural heritage of Myanmar (in combination with political change in the country in 2010/2011) largely explains the movement’s success. Meanwhile, the set of sophisticated tactics (including inter alia demonstrations, Thai Baan research, 24/7 monitoring of the dam site, and spiritual activities) was decisive for the efficacy of the movement against Thailand’s Kaeng Suea Ten Dam.  相似文献   

泰国近海习见有毒立方水母和钵水母的遗传分析   总被引：2，自引：0，他引：2       下载免费PDF全文

刘瑞娟  肖洁  张学雷  Charatsee Aungtonya 《海洋学报》2016,38(6):51-61

本研究利用线粒体16S rDNA和核基因18S rDNA片段,对泰国沿海常见的有毒水母进行遗传分析,并比较了2个基因片段作为通用分子标记,在研究水母类多个纲的遗传多样性中的应用。研究发现,泰国近海的有毒水母存在较高的遗传多样性,所获得的32个样品可以分为9个种,包括4种钵水母、4种立方水母和1种水螅水母。然而,完全确定各种的分类地位,还需要更多的形态、生活史等方面信息。两个基因片段均能明确区分各种类,但核基因18S序列比线粒体基因片段更为保守。根据16S基因片段序列计算水母种内和种间的K2P(Kimura 2-parameter)遗传距离,发现所研究的9个水母种类,种内遗传距离在0~0.050之间,其中94%的种内遗传距离小于0.040,同纲种间的遗传距离为0.204~0.474,其中91%的种间遗传距离大于0.250;而利用18S基因,种内距离在0~0.002之间,同纲种间距离为0.008~0.066(平均为0.038,SE=0.006)。16S的AT碱基含量明显高于核基因18S,且16S的碱基含量在不同纲之间有显著差异,进一步表明水母线粒体16S基因的突变率相对较高,适合研究水母较低分类阶元以及种下的遗传差异。  相似文献

A survey of imposex in muricids from 1996 to 2000 and identification of optimal indicators of tributyltin contamination along the east coast of Phuket Island,Thailand     

Bech M 《Marine pollution bulletin》2002,44(9):887-896

The present investigation is the most extensive survey of imposex in gastropods from the west coast of Thailand. Imposex in Thais distinguenda increased significantly (p < 0.001; Chi Square test for trend) from 1996 to 2000 at 21 stations in Phangna Bay, Thailand. Females with imposex increased, extending from 3.5 km in 1996 to 10 km from the harbour areas in 1999 and 2000. Increasing intensity of imposex was also observed for Thais bitubercularis from 1996 to 2000. The less sensitive species: Morula musiva, Morula granulata, Morula margariticola and Thais rufotincta only developed imposex at the three main areas of intense shipping activities. T. bitubercularis and T. distinguenda are recommended as indicators of tributyltin (TBT) in Southeast Asia because of their sensitivity and wide distribution in the region. The results suggest that TBT contamination is worsening, against global trends, because regulations prohibiting the use of TBT-based paints, do not exist in Thailand.  相似文献   

The state and its agencies in coastal resources management: The political ecology of fisheries management in Pattani, southern Thailand   总被引：1，自引：0，他引：1  

May Tan-Mullins 《Singapore journal of tropical geography》2007,28(3):348-361

Various stakeholders contribute to the current state of resource management in the inshore fisheries of Pattani, southern Thailand. Taking the state, empowered by national legislation, as the main agent of enforcement, this paper uses an actor-oriented approach derived from political ecology to evaluate how key agents in state agencies at provincial and district levels translate Thai political and legal systems at the local level; more specifically, how cross-scalar institutional linkages and translations affect coastal resources management and the access of village-based, small-scale fishermen to coastal resources. The paper shows that trans-scalar interpretations have created a space of contestation and negotiation in resource governance at the local level that reveals intrastate tensions. Based on extensive fieldwork, the paper demonstrates that access to environmental resources at the local level is highly influenced or regulated by the unequal power relations between different actors at various levels.  相似文献

Healthier Geographies: Mediating the Gaps between the Needs of People Living with HIV and AIDS and Health Care in Chiang Mai,Thailand     

Vincent J. Del Casino  Jr. 《The Professional geographer》2001,53(3):407-421

In this article, I contribute to our understanding of the plurality of approaches that construct the geographies of health care through an examination of the distribution of health care services for people living with HIV/AIDS (PLWHA) in Chiang Mai Province, Thailand. In particular, I focus on the development of a network of support groups for PLWHA in order to examine the differences in the sociospatial organization of these groups, the practices of social actors participating in the groups' activities, and how these activities are mediated through place‐based social relations. The first section of the article analyzes the spatial distribution of PLWHA support groups in relation to the distribution of AIDS cases over two time periods, 1994 and 1997. The second section goes below the surface of the spatial distribution, examining similarities and differences in PLWHA support groups through an analysis of survey data collected on thirty‐five groups in 1997. The final section deepens this examination through an analysis of ethnographic data collected on the outreach efforts of one nongovernmental organization (NGO) and one PLWHA support group with which it worked. Each section offers opportunities for the extension of our understanding of the development of PLWHA support groups, their distribution in relation to the spread of AIDS cases, and their place‐based meanings.  相似文献   

Lithostratigraphy of Permian marine sequences, Khao Pun Area, central Thailand: Paleoenvironments and tectonic history     

Vichai Chutakositkanon  Punya Charusiri and  Katsuo Sashida 《Island Arc》2000,9(2):173-187

Geologic mapping and subsurface lithostratigraphic investigations were carried out in the Khao Pun area (4 km²), central Thailand. More than 250 hand specimens, 70 rock slabs, and 70 thin sections were studied in conjunction with geochemical data in order to elucidate paleoenvironments and tectonic setting of the Permian marine sedimentary sequences. This sedimentary succession (2485 m thick) was re‐accessed and re‐grouped into three lithostratigraphic units, namely, in ascending order, the Phu Phe, Khao Sung and Khao Pun Formations. The Lower to lower Upper Permian sedimentary facies indicated the transgressive/regressive succession of shelf sea/platform environment to pelagic or abyssal environment below the carbonate compensation depth. The sedimentological and paleontological aspects, together with petrochemical and lithological points of view, reveal that the oldest unit might indicate an Early Permian sheltered shallow or lagoonal environment. Then the depositional basin became deeper, as suggested by the prolonged occurrence of bedded chert‐limestone intercalation with the local exposure of shallower carbonate build‐up. Following this, the depositional environment changed to pelagic deposition, as indicated by laminated radiolarian (e.g. Follicucullus sp.) cherts. This cryptic evidence might indicate the abyssal environment during middle Middle to early Late Permian; whereas, previous studies advocated shelf‐facies environments. Following this, the depositional condition might be a major regression on the microcontinent close to Indochina, from the minor transgressive/regressive cycles that developed within a skeletal barrier, and through the lagoon with limited circulational and anaerobic conditions, on to the tidal flat to the sheltered lagoon without effective land‐derived sediments.  相似文献
