Does flagship species tourism benefit conservation? A case study of the golden snub-nosed monkey in Shennongjia National Nature Reserve

Tourism has been widely used as a conservation strategy that directly compensates local people or management authorities, thereby contributing to development and creating incentives to preserve the landscape. Reserves or parks that are inhabited by flagship species may be able to generate more revenue through tourism than those without such species because flagship species have great potential for raising funds and creating publicity for conservation goals. In this paper, we examine flagship species tourism...     

广西元宝山自然保护区黑熊春季觅食生境特征

在广西元宝山自然保护区野外设置了82个20 m×20 m样方,初步分析黑熊春季觅食地生境特征,对16个生态因子进行主成分分析和单因子适合度检验。结果表明：黑熊觅食地生境特征的主要影响因子为水源距离、海拔和灌木密度;次要因子为食物丰富度因子(树径、乔木密度、乔木距离、灌木距离)、地理性因子(坡向、坡位、坡度)、干扰性因子(树桩密度、树桩距离、倒木距离、人为干扰距离)和微生境因子(避风性、郁闭度)。对黑熊的生境喜好程度分析发现：水源丰富、一定海拔、避风性适中、植物茂盛(乔木密度、灌木密度、乔木距离、灌木距离)、坡向向阳、郁闭度好(30 %～80 %)、坡度较大的山嵴和山坡位为其最适生境。由于人类活动增加,干扰因子(树桩密度、树桩距离、倒木距离、人为干扰距离)成为影响黑熊生境选择的重要因素。     

从CSSCI看《自然辩证法研究》的学术影响

基于中文社会科学引文索引CSSCI1998—2004年的统计数据,从被引规模—频次分布、历年的被引次数、被引半衰期、高频被引著者等角度,对《自然辩证法研究》作了文献计量学分析,计量结果可为作者、编者和读者提供参考。     

湖北网湖湿地自然保护区两栖爬行动物资源调查

2004年对湖北省阳新县网湖湿地自然保护区的两栖类和爬行类进行了系统调查,分别记录到两栖类27种、爬行类38种．对它们的物种组成、地理区系特点和保护等级进行了研究,并提出了保护建议．     

恩格斯《自然辩证法》科学方法论及其当代意蕴

恩格斯《自然辩证法》是一部马克思主义经典著作,以辩证唯物主义认识论为指导,对自然科学发展情况进行了全面考查,系统地论述了科学方法论,总结了科学方法论的理论特征,对科学方法论的运用、创立和发展作出了重大贡献。今天我们学习和研究自然辩证法,掌握科学方法论,对于推动社会进步、促进科技发展、贯彻新的发展理念和提高科学素养具有重要意义。     

生态自然观与当代全球性生态危机反思

生态自然观是系统自然观在人类生态领域的具体体现,是辩证唯物主义自然观的现代形式之一。当代全球性生态危机是系统的辩证的生态自然观确立的现实根源;而现代生态自然观的践行为缓解生态危机提供了重要的哲学依据。当前,面临生态危机的严重威胁,我们必须重新审视人与自然的关系,从理论的层面寻找解决生态危机的可实施的良策。本文以生态自然观为理论根基,试图用系统思维方式探究走出生态困境的有效路径。

存款准备金率变动对股市影响的实证研究

运用VAR模型的G ranger因果检验和脉冲响应函数分析研究了中央银行存款准备金率变动对沪深300指数的影响,并通过方差分解分析前者对后者的贡献度。得出的结论是存款准备金率变动对股市波动在短期内存在一定负方向的影响,股市波动对存款准备金率则无影响。但在长期内,存款准备金率变动对股市影响很小。最后在此基础上提出相关的货币政策的建议。     

The amphibians and reptiles of Nosy Be (NW Madagascar) and nearby islands: a case study of diversity and conservation of an insular fauna

Surveys of the amphibians and reptiles on Nosy Be (an island off north-west Madagascar) and nearby islands were undertaken between 1991 and 2001 and are discussed here in view of biodiversity considerations and conservation efforts. Since Nosy Be is the type locality of several amphibian and reptile taxa, their exact status is of crucial importance for the nomenclatural stability of many groups of the Madagascan herpetofauna. A total of 20 amphibian and 61 reptile species (excluding marine reptiles) was confirmed for this archipelago. Other species (Mantidactylus horridus, Androngo elongatus, Typhlops madagascariensis, T. reuteri, Micropisthodon ochraceus and Pararhadinea melanogaster) were not found during these inventories, but are quoted in the literature or housed in herpetological collections, and are considered as likely to be present at Nosy Be. A further 18 taxa are tentatively excluded from its fauna, due to biogeographic incongruence and/or lack of reliable voucher specimens. Few taxa are so far only known from the island; they may represent endemics or may have been overlooked on the adjacent mainland. They are respectively Stumpffia pygmaea, Mabuya lavarambo, Lygodactylus h. heterurus, Lycodryas granuliceps and Typhlops reuteri. Heterixalus tricolor too is likely to be present on Nosy Be only, but the difference with respect to taxa present on the mainland needs to be confirmed. Several species are known from nearby islands and islets surveyed (11 amphibians and 26 reptiles). A few of them (Heterixalus 'variabilis', Kinixys belliana, Furcifer oustaleti, Mabuya comorensis, Paracontias milloti) are present on some of these islands but have not yet been found on Nosy Be. Much of the field research was conducted at Lokobe, a strict nature reserve still characterized by good forest coverage (typical of the Sambirano Domain), and an important area of biodiversity. With 15 amphibian and 45 reptile species, Lokobe hosts 81% of the overall Nosy Be herpetofauna: of the species found during our surveys, only Heterixalus tricolor, Hoplobatrachus tigerinus, Gehyra mutilata, Phelsuma dubia and Crocodylus niloticus were only found outside the reserve. In view of this, the protection of Lokobe should be assured and reinforced. Except for Lokobe, habitats on Nosy Be are largely anthropogenic, and have a lower species diversity, especially where there is intensive agriculture. At other sites (e.g. ylang-ylang and coffee plantations) and in forested bands along roads, species diversity is still high: careful management of these anthropogenic habitats might also assure the survivorship and conservation of a diverse herpetofauna outside the protected area.
