摘要
生物入侵是一项严峻的全球性挑战,它对生态系统产生了深远影响,并推动了环境变化。虽然入侵动物或植物物种的分布已受到广泛关注,但我们对入侵藻类和蓝藻在全球大陆淡水生态系统中的流行情况的了解仍然有限。为了研究有多少淡水藻类和蓝藻被检测为入侵者,我们进行了一次全面的文献计量分析。结果显示,有 72 个物种被报告为入侵物种,其中主要是 R. raciborskii、D. geminata 和 C. furcoides。只有 52% 的报告对环境影响进行了量化或分析。在已记录的影响和环境变化中,浮游植物结构和多样性的变化是最常见的报告,其次是毒素的产生,尤其是与入侵蓝藻物种有关的毒素。从地域上看,报告明显集中在非洲和亚洲。同时,捷克共和国和波兰在被列为入侵物种的数量上遥遥领先。这种地域偏差表明,我们对入侵淡水藻类和蓝藻物种真实分布情况的了解还存在很大差距。
Invasive freshwater algae and cyanobacteria are overlooked: insights from a bibliometric study
Biological invasions represent a critical global challenge, profoundly impacting ecosystems and driving environmental change. While the distribution of invasive animal or plant species has received considerable attention, our understanding of the global prevalence of invasive algae and cyanobacteria in continental freshwater ecosystems remains limited. With the aim of studying how much freshwater algae and cyanobacteria are being detected as invaders, we conducted a comprehensive bibliometric analysis. It revealed 72 reported species as invasive, with R. raciborskii, D. geminata, and C. furcoides emerging as principal ones. Only 52% of the reports quantified or analyzed environmental impacts. Among the documented impacts and environmental alterations, changes in phytoplankton structure and diversity were the most frequently reported, followed by toxin production, particularly associated with invasive cyanobacteria species. Geographically, there is a noticeable concentration of reports, with Africa and Asia being underrepresented. Meanwhile, the Czech Republic and Poland emerge as leaders in the number of species classified as invaders. This geographical bias suggests a significant gap in our understanding of the true distribution of invasive freshwater algae and cyanobacteria species.
期刊介绍:
Hydrobiologia publishes original research, reviews and opinions regarding the biology of all aquatic environments, including the impact of human activities. We welcome molecular-, organism-, community- and ecosystem-level studies in contributions dealing with limnology and oceanography, including systematics and aquatic ecology. Hypothesis-driven experimental research is preferred, but also theoretical papers or articles with large descriptive content will be considered, provided they are made relevant to a broad hydrobiological audience. Applied aspects will be considered if firmly embedded in an ecological context.
