Purpose of Review

Assisted migration is increasingly proposed as a proactive management strategy to mitigate the consequences of maladaptation predicted under climate change. Exploring the social and academic structure of the field, its research gaps, and future research directions can help further the understanding and facilitate the implementation of assisted migration strategies. Here we used bibliometric analysis to examine the intellectual, social, and conceptual structures of assisted migration research to identify gaps and opportunities for future research. Bibliometric data based on publications on assisted migration were collected from Scopus and Web of Science databases using assisted migration and climate change or their synonyms as queries. Metadata were merged, processed and several networks were constructed.

Recent Findings

Co-citation and keyword co-occurrence networks identified three major clusters focused on (i) theory and risk of assisted migration of threatened and endangered species, (ii) impact of climate change on realized and fundamental climate and geographic niches, and (iii) assisted population migration. Collaboration network analysis identified three social core hubs: North America, Europe, and Australia, with the USA and Canada being the most productive and the most collaborative countries.

Summary

We conclude that future research is expected to concern mainly the assessment of physiological response of species and populations to extreme climate events such as drought and frost, and the contribution of non-climatic factors and biotic interactions in local adaptation and population performance under climate change. Social core hubs distinguished in this work can be used to identify potential international research and training collaborators necessary to address gaps and challenges underlying assisted migration implementation.

辅助移民研究的结构和演变的文献计量分析

审查目的

辅助移民越来越多地被提议作为一种积极的管理策略，以减轻气候变化下预测的适应不良的后果。探索该领域的社会和学术结构、研究差距和未来的研究方向，有助于进一步理解和促进辅助移民战略的实施。在这里，我们使用文献计量分析来检查辅助移民研究的知识、社会和概念结构，以确定未来研究的差距和机会。使用辅助移民和气候变化或其同义词作为查询，从 Scopus 和 Web of Science 数据库收集基于辅助移民出版物的文献计量数据。元数据被合并、处理并构建了几个网络。

最近的发现

共引和关键词共现网络确定了三个主要集群，重点是 (i) 受威胁和濒危物种辅助迁移的理论和风险，(ii) 气候变化对已实现和基本气候和地理生态位的影响，以及 (iii)协助人口迁移。协作网络分析确定了三个社会核心中心：北美、欧洲和澳大利亚，其中美国和加拿大是生产力最高和协作能力最强的国家。

概括

我们得出的结论是，未来的研究预计主要关注物种和种群对干旱和霜冻等极端气候事件的生理反应评估，以及非气候因素和生物相互作用对气候变化下局部适应和种群表现的贡献。在这项工作中突出的社会核心中心可用于确定潜在的国际研究和培训合作者，以解决协助移民实施背后的差距和挑战。
