Abstract

Crabs are the most dominant groups in mangrove ecosystem and play a vital role in building and sustaining the structure and function of the mangrove ecosystems. However, a systematic evaluation of global research status of mangrove crabs is still lacking. Here, a bibliometric analysis based on the Science Citation Index Expanded (SCI-E) was carried out to provide insights into research activities, tendencies, and challenges of the mangrove crabs from 1980 to 2016. The results showed that the average annual output of the publications was low. Brazil took a leading position out of the 63 countries/territories with the largest number of publications, followed by USA, Australia, China, and Germany. Journal of Experimental Marine Biology and Ecology was the most popular journal. The reproductive ecology (e.g., reproduction), population ecology (e.g., population structure), and their relationship were the mainstream. The estuarine ecosystem and the method of stable isotope received ecologists’ favor. Behavioral ecology (e.g., bioturbation), ecosystem function (e.g., carbon), and the ecological effect among them were the main issues in this field. Biodiversity was a new hot topic. Brazil, Australia, USA, China, and Kenya were the top five hot regions among the 53 hot countries on a global scale. Different regions have different hot topics. The breeding ecology was the most popular theme in the Americas region, the ecological effects of crabs were the most hotstops in the Africa-East Asia region and the East and South Asia-Oceania region. The challenges of the development were not comprehensive and uneven on a global scale. There was a certain number of countries with mangrove distributions were still outside this field, such as most of the western and northeastern countries of Africa (e.g., Angola), some Central American countries (e.g., Guatemala), and some western and southeast Asian countries (e.g., Cambodia). Furthermore, we found that some topics were ignored or lagged in each territory. Our results highlight that the global research status of mangrove crab is still at a relatively backward stage, and regional development is extremely unbalanced.

绘制全球红树林蟹类的时空动态,揭示其现状与挑战:1980-2016年研究成果的文献计量评估
螃蟹是红树林生态系统中最具优势的类群,对红树林生态系统结构和功能的建立和维持起着至关重要的作用。然而,对全球红树林蟹类的研究现状仍缺乏系统的评价。基于科学引文索引扩展(SCI-E),对1980 - 2016年红树林蟹类的研究活动、趋势和挑战进行了文献计量分析。结果表明,我国期刊年平均产出量较低。在发表论文最多的63个国家/地区中,巴西排名第一,其次是美国、澳大利亚、中国和德国。《实验海洋生物学与生态学杂志》是最受欢迎的杂志。生殖生态学(如繁殖)、种群生态学(如种群结构)及其关系是主流。河口生态系统和稳定同位素方法受到生态学家的青睐。行为生态学(如生物扰动)、生态系统功能(如碳)及其之间的生态效应是该领域的主要研究内容。生物多样性是一个新的热点话题。在全球53个热点国家中,巴西、澳大利亚、美国、中国和肯尼亚是排名前五的热点地区。不同的地区有不同的热点话题。美洲地区最关注的是养殖生态,非洲-东亚地区和东亚-南亚-大洋洲地区最关注的是蟹类生态效应。发展的挑战在全球范围内并不全面和不平衡。有一定数量的红树林分布的国家仍在这一领域之外,如非洲西部和东北部的大部分国家(如安哥拉)、中美洲的一些国家(如危地马拉)和一些西部和东南亚国家(如柬埔寨)。此外,我们发现在每个领域都有一些主题被忽略或滞后。研究结果表明,全球红树林蟹的研究现状仍处于相对落后的阶段,区域发展极不平衡。
