Magick as an Alternative Symbolic: Enacting Transhuman Dialogs

This essay examines Neo-Pagan practices of magick and, via Rogers's criteria for a transhuman theory of communication, argues that these practices enact a transhuman dialog that has potential to enhance environmentally sustainable ways of living. Magick helps to re-member immanence in all entities through learning to exercise modes of sensation that have become dormant. Of central importance to the practice of magick is taking eros seriously while expanding awareness beyond the human to the other-than-human. Such sensory experiences and relationships serve to recover the concrete from the dominance of the abstract, eros from the dominance of rationality, the material from the dominance of the ideational, and the natural from the dominance of culture. This essay works to bridge theoretical and practical implications of dialogs with nature by identifying practices that can overcome trained incapacities that block sensual, dialogic relations with the other-than-human world, while also acknowledging limitations in the transformative potential of Neo-Pagan ideologies and practices.

Contribution of tourism development to protected area management: local stakeholder perspectives

Ecotourism in protected areas plays an important role in establishing mutually beneficial relationships among local people, the protected area, and tourism that are essential in protected area management. However, to properly manage protected areas, local people should be major stakeholders in order to maximize local economic benefits and obtain support for conservation efforts. This study assesses the current status of local people's economic participation in tourism in the Wolong Nature Reserve using a questionnaire survey. Through evaluation of geographic origin, income, and occupational distribution of operators engaged in tourism-related business, we identified and discussed constraints and opportunities for economic participation of local people. Economic inequity was found among local people, as well as between locals and non-locals, due to limited startup capital and operational skills. At present, only a small percentage of local people receive revenue directly from tourism. In addition, economic leakage and local dependence on natural resources still exist in the study area. To promote ecotourism and sustainable development, the relationships among tourism, local people, and biodiversity conservation in the study area must be strengthened. According to the findings, some suggestions are offered to protected area managers to foster better relationships.     

双台河口自然保护区滨海湿地的维管束植物区系特征

辽宁双台河口自然保护区滨海湿地维管束植物区系中有56科117属155种维管束植物,有蔷薇科、菊科、禾本科、蓼科、豆科、唇形科、香蒲科、眼子菜科、莎草科等9大科51属76种,9大科的属数、种数占区系总属数和总种数的43.59%、49.03%;区系内小科、单种属多,说明科、属的分化程度较高。区系中有15种盐生植物、25种水生植物、34种湿生植物、79种中生植物和4种旱生植物,湿地植被的优势种和建群种均为盐生植物、水生植物和湿生植物,这表明保护区内滨海湿地植被的形成不仅受海水、土壤盐渍化影响,更受辽河径流淡水的影响。区系中有地面芽植物、地下芽植物72种,占总种数的46.45%,说明冷湿气候对保护区内滨海湿地植被的形成有重要作用。区系中有世界分布属31属,占区系总属数的26.50%,这反映了湿地植被的隐域性;有温带分布属57属、热带分布属23属,分别占区系总属数的48.72%、19.66%,这分别表明保护区滨海湿地植被具有一定的地带性特征,雨量充沛、冬季气温较高的海洋性气候特征对湿地中起源于热带的维管束植物生存限制较小。     

Optimization of tourism impacts within protected areas by means of genetic algorithms

The search for a balance between nature conservation and tourism development within protected areas is becoming an increasingly multifaceted problem worldwide, as outlined by an increasing number of authors and highlighted at several international events. Since it is unlikely that all management objectives will reach their optimum values simultaneously, an optimization approach is required to meet multiple, conflicting goals and to obtain an overall trade-off in terms of the conceived objectives.     

What makes affirmative action‐based hiring decisions seem (un)fair? A test of an ideological explanation for fairness judgments

Studies show that Whites tend to show the lowest level of support for affirmative action (AA) policies. Opponents of AA often argue that this is because it violates principles of meritocracy. However, self‐interest (based on social identification with those adversely affected) could also explain their opposition. In three studies, we varied whether an Asian or White male is adversely affected by AA to test another explanation; namely, that Whites' fairness judgments are based on both the adversely affected person's race and the fairness evaluator's ideological beliefs. Although we found some support for the meritocratic explanation, this was not sufficient to explain why Whites view AA as (un)fair. Instead, we found strong support for our prediction that Whites who are opposed to equality perceive more unfairness when a White (vs. Asian) was harmed by AA, whereas Whites who endorse egalitarian ideologies perceive the opposite. This finding suggests that neither self‐interest nor meritocratic explanations can fully account for Whites' opposition to AA. Copyright © 2014 John Wiley & Sons, Ltd.

滨海湿地类自然保护区的成本-效益研究——以江苏盐城湿地珍禽国家级自然保护区为例

以江苏盐城湿地珍禽国家级自然保护区为例,分析了滨海湿地生态系统所提供的生态系统服务及保护该系统所产生的成本.采用市场价值法、影子工程法和专家评估法估算了保护区内滨海湿地生态系统服务价值.2010年盐城保护区内滨海湿地生态系统产生的保护成本为8.18× 109元,其中管理成本为1.95× 107元,机会成本为8.16× 109元;保护区产生的效益为1.83× 1010元.结果表明,盐城保护区获得的效益远大于其付出的成本,盐城保护区的存在具有经济学上的收益优势.因此,在盐城滨海湿地建立自然保护区具有巨大的生态效益,这种优势更多地体现为长期的综合效益,且难以用货币形式直接兑现.对待自然保护区建设与管理应形成整体、长期的理念,不能因短期利益和局部利益而牺牲自然保护区,真正做到对保护区的永久保护和持续利用.     

鄱阳湖大型底栖动物群落结构的空间分布及影响因子研究

由于受人类活动干扰的加强以及受与长江干流之间"江湖关系"变化的影响,近年来鄱阳湖水生生态系统的状况及变化受到较多关注。对底栖动物群落结构的研究将有助于了解鄱阳湖生态系统结构现状及影响因子,对鄱阳湖保护对策的制定形成有效支撑。2016年7月,对鄱阳湖湖区(分别于鄱阳湖保护区和南矶山保护区)的底栖动物群落结构及相关环境因子进行了调查。调查共发现大型底栖动物27种,隶属于5门8纲,平均密度为48.40 ind.·m-2,其中主要以软体动物门为主;平均生物量为28.12 g·m-2,亦主要由软体动物门贡献。湖区主要优势种为河蚬(Corbicula fluminea)(优势度y=0.0655)、铜锈环棱螺(Bellamya aeruginosa)(y=0.0336)、霍甫水丝蚓(Limnodrilus hoffmeisteri)(y=0.0268)。底栖动物密度、生物量及多样性指数均呈现出鄱阳湖保护区高于南矶山保护区的格局,且二者在群落组成上有明显差异,鄱阳湖自然保护区主要以腹足纲和寡毛纲为主,南矶山自然保护区主要以瓣鳃纲和腹足纲为主。典范对应分析的结果显示,鄱阳湖保护区主要受到高水深、低浊度及高溶氧的影响;南矶山保护区各样点之间群落相似性较差,分别受不同因子的影响,这表明在各区域内部,局域微生境在局域群落结构的塑造上起主要作用,因此该区域内生态系统的保护应适当考虑空间尺度。     

A herbivore specific grazing capacity model accounting for spatio-temporal environmental variation: A tool for a more sustainable nature conservation and rangeland management

Grazing with livestock is a common feature of nature and rangeland management. Although both aim at different, seemingly opposing goals, i.e. maintenance of biodiversity values versus maximization of animal production, they nonetheless have a common interest in maintaining the rangeland or natural environment in a state that ensures either the first or the second goal. In order to accomplish an effective and efficient grazing management, in terms of grazer density, grazer composition, grazing seasonality, and to prevent under- and overgrazing, a grazing capacity model (GCM) was developed, that should be applicable in both rangeland and nature conservation management conditions and that takes spatio-temporal environmental variation into account. This spatio-temporally dynamic model considers crucial variables at both the terrain and the grazer level, such as (seasonally) fluctuating forage yield, forage quality, plant palatability, accessibility of the area, soil erosion vulnerability, animal nutritive requirements, animal behaviour and general habitat condition. It predicts the optimal grazer species and density, taking into account the seasonal variation in animal needs and fluctuating terrain characteristics. A sensitivity analysis was conducted to define each parameter's relative impact on the final outcome of the model.We present the GCM outline and illustrate the functionality of this model for Shetland ponies and Highland cattle, grazing in a temperate coastal dune environment. According to the model, seasonal fluctuations in optimal grazer densities occur: the area can support higher densities in summer and autumn than it can during winter and spring. With the current density of grazing animals and the choice for year-round grazing at non-fluctuating animal densities, the model consequently predicts overgrazing in winter and undergrazing in summer and autumn. Both undergrazing and overgrazing scenarios might lead to non-sustainable situations in the future.
