Expanded response data from Perrin et al. - Contrasts in Public Perception of the Role of Alien Species in Climate Driven Species Turnover

Responses given by 30 respondents from 3 different interest groups on their attitudes to climate change driven species turnover in Norwegian freshwater lakes. The groups are a) recreational fishers, b) individuals responsible for management decisions regarding freshwater lakes or rivers and c) academics involved in research regarding freshwater lakes or rivers. Use of square brackets indicates details have been altered so as to preserve anonymity of respondents. A total of 30 interviews were conducted between August of 2019 and April of 2020. Interviews lasted anywhere from 10 to 50 minutes. Of the 30 interviews, 16 were conducted in person, with the remaining 14 conducted via web meeting. Interview respondents were chosen using the snowball method, as described by Miles and Huberman (1994). This requires an initial pool of contacts, who subsequently nominate other respondents that are suitable for the study. In compliance with requirements of the Norwegian National Research Ethics Committee, all respondents were given an overview of the topic beforehand, assured that their responses would be anonymous, and informed of the intended use of their responses. All interviews were anonymously recorded and subsequently transcribed verbatim. Any details which might have allowed the individuals to be identified based on descriptions of their roles or locations were removed. As interviews were anonymous, ethics approval from the Norwegian National Research Ethics Committee was not required.本数据集包含来自3个不同兴趣群体的30名受访者针对挪威淡水湖泊气候变化驱动物种更替的态度反馈。三个群体分别为：a) 休闲垂钓者；b) 负责淡水湖泊或河流管理决策的人员；c) 从事淡水湖泊或河流研究的学者。使用方括号表示已对细节进行调整，以保护受访者的匿名性。2019年8月至2020年4月期间共开展30次访谈，单次访谈时长介于10至50分钟之间。其中16次为线下访谈，剩余14次通过网络会议完成。本次访谈的受访者采用滚雪球抽样法（snowball method）选取，该方法如Miles与Huberman（1994）所述，需先构建初始联系人池，再由联系人提名符合研究要求的其他受访者。本研究遵循挪威国家研究伦理委员会的相关要求，所有受访者提前获知研究主题，其答复将被匿名处理，并被告知答复的预期用途。所有访谈均进行匿名录音，并随后逐字转录。所有可能通过角色或地点描述识别受访者身份的细节均已被移除。由于本次访谈采用匿名形式，因此无需获得挪威国家研究伦理委员会的伦理审批。
