Michigan Mute Swan Management: A Case Study to Understand Contentious Natural Resource Management Issues

U.S. state fish and wildlife agencies have responded to perceived ecological and social threats posed by mute swans by implementing population control strategies. In Michigan, some stakeholder groups have vocally opposed particular control activities. To better understand and characterize key aspects of the underlying media dialogue about mute swan management in Michigan, one factor in the development of public perceptions about wildlife issues, we conducted a qualitative content analysis of Michigan-specific online news articles. Results revealed tensions between stakeholder groups about management priorities were rooted in differing ideas about healthy social and ecological systems, appropriate wildlife behavior, and the acceptability of lethal control (i.e., shooting living birds). Characterizing which stakeholder groups aligned with particular arguments might allow managers to tailor and direct messaging to specific audiences.     

Seasonal variations in the diet and food selection of the Algerian hedgehog Atelerix algirus

The Algerian hedgehog Atelerix algirus is an insectivorous species. However, the exact composition of its natural diet remains largely undetermined, especially in relation to seasonal variations in food availability. From March to November, we simultaneously analysed the composition of 180 hedgehog faecal samples and food availability in the Soumman Valley, Algeria to assess food selection in this species. The faeces contained 196 different prey species, of which 92% belonged to the class Insecta. The highest prey species diversity was found in the Coleoptera order (100 species recorded) and the highest species occurrence was found in Hymenoptera (65% of the prey items, mainly represented by the harvester ant Messor barbarus, a crop-ravaging species). This study shows that the Algerian hedgehog is mainly a generalist species with a diet that is strongly linked to food availability. However, seasonal variations were observed in prey selection, and a notable shift in food preference was observed during autumn. The exact nature of these changes in feeding behaviour remains to be investigated, notably in relation to changes in energy requirements of this species before hibernation, in terms of quantity and/or quality.     

涉农本科高校畜牧兽医专业双语教学调查分析

双语教学符合经济全球化对高等教育国际化的要求,可为国家培养懂专业又懂外语的复合型人才,是我国高等教育改革的热点之一。论文从师资水平、学习双语课程中的困难、双语教材的使用情况以及课堂教学效果四个方面调查涉农本科高校畜牧兽医专业双语教学现状。调查证实了双语教学在使学生掌握专业知识的同时又能提高学生的英语水平;同时还发现河南省涉农本科高校畜牧兽医专业双语教学存在如下问题:双语教师专业能力较强而外语运用能力较弱,学生双语学习的主要困难在于专业术语和词汇,教材的使用缺乏规范。     

The Status of Library Automation in the 1890 Land-Grant Institutions

ABSTRACT

Seventeen historically black colleges and universities (HBCUs) had the unique distinction of being designated land-grant institutions in 1890. There is surprisingly little information in the library literature describing the state of automation in academic libraries and even less about the state of automation in the seventeen historically black land-grant universities. The authors designed a questionnaire that would serve as the instrument for a base survey of the state of automation in these libraries. The results of this survey are presented in the following article.     

农业文献的翻译方法

随着国际农业交流的日益发展,农业文献翻译正在彰显出愈加重要的作用.在农业文献翻译过程中,通过翻译理论的指导,选择适当的翻译方法,不仅能够保证翻译质量,并且可以加强理解沟通.本论文主要对比分析了Peter Newmark提出的语义翻译和交际翻译这两种翻译方法,对基本农业文献的形式进行了划分归类,并举例说明.文章指出在翻译实践中,对原文形式的正确分析理解和对两种翻译方法特性的灵活掌握,是达到佳翻译效果的有效途径.     

跨区作业经济效益影响因素剖析

根据2004年跨区作业调查,计算了联合收割机跨区机收的经济效益,并着重指出了跨区作业经济效益下降的实际问题;通过深入分析其中的原因,指出影响跨区作业经济效益的两大主要因素,是信息系统不完善和散机的无序流动。     

论农业生态学及其发展趋势

农业生态学是研究农业生物与农业环境之间相互关系及其作用机理和变化规律的农业应用学科。它在促进农业可持续发展等方面起着基础作用、综合作用、带动作用、关键作用和渗透作用。农业生态学的发展经历了萌芽期、产生期、发展期 ,目前已迈入完善期。新世纪农业生态学应朝着以下方面发展 :(1 )研究方法上 ,加强实验研究 ;(2 )实践应用上 ,强调实用性和可操作性 ;(3 )理论研究上 ,深化农业应用基础研究 ;(4 )技术体系上 ,突出系统性、完整性和创新性 ;(5 )硬件建设上 ,加大投入力度 ;(6)软件环境上 ,加强农业生态教育、增强生态意识、提高生态素质 ;(7)人才培养上 ,大力培养具有创新意识和实践能力的复合人才。     

固原市中雨、大雨、暴雨相似预报系统的设计与实现

[目的]设计和推广固原市中雨、大雨、暴雨相似预报系统。[方法]采用C#.Net2005作为开发平台,基于MSSQLSERVER2005数据库系统,统计固原市自1960年以来逐年5～9月出现中雨、大雨、暴雨过程的高空环流形势,以500 hPa为主,700 hPa和地面形势为辅,分别计算500、700 hPa的相似离度,按照历史上出现过的最相似个例来类推预测今后将要出现的天气过程和天气现象。[结果]该系统设置非常人性化和模板化,系统设置仅需要一次设置即可,除非需要更改设置,系统运行一般不需要更改参数,系统会自动读入设好的参数,方便业务人员使用,同时也解决大量数据在一个字段存贮的难题。系统在设计的过程中考虑了推广应用问题,设计上具有通用性和可移植性。[结论]该系统弥补数值预报产品漏报中雨、大雨、暴雨的可能性。
