摘要:

目的 分析全球生物多样性信息网络(GBIF)平台上我国福寿螺出现记录的时空分布特征及其与遗传溯源的关联,为福寿螺热点定殖区和风险区的精准监测防控提供参考。 方法 收集2001—2024年GBIF平台上我国福寿螺有效出现记录,采用SPSS 26.0软件进行描述性统计分析;系统检索同时间段内我国福寿螺遗传溯源研究文献,提取种群遗传结构与溯源证据,综合分析二者关联性。 结果 共筛选有效记录1 785条,覆盖我国17个省级行政区。记录类型以人类观察为主(1 669条,93.50%),坐标不确定度均值为70.42 m,空间精度较高。有效记录的纬度范围为18.298 967°N(海南)至32.078 623°N(江苏),经度范围为100.787 644°E(云南)至121.924 861°E(台湾),呈现“南多北少”的分布特征。台湾(1 435条,80.39%)、湖南(108条,6.05%)和广东(85条,4.76%)为3大核心记录热点地区。时间上呈“零星发展-缓慢起步-暴发增长”3个阶段变化特征,2001—2010年共记录4条;2011—2020年共记录503条(年均50.3条),2021—2024年记录数激增至1 278条(年均319.5条),2024年达峰值386条,其中台湾贡献364条(占94.30%,364/386)。文献复习纳入9篇遗传溯源研究,结果显示小管福寿螺为我国绝对优势种,来源均指向南美洲阿根廷和巴西,台湾种群遗传结构最为复杂,长江下游(江苏、上海)小管福寿螺遗传多样性较高(单倍型多样性 = 0.627),部分GBIF记录热点与遗传多样性高值区高度吻合。 结论 部分GBIF记录热点与福寿螺高遗传多样性区域空间分布高度一致,台湾为核心扩散起点,长江下游存在独立入侵事件和持续北扩态势。

Abstract:

Objective To analyze the spatiotemporal distribution characteristics of Pomacea snail presence records in China in the Global Biodiversity Information Facility (GBIF) platform and their associations with genetic tracing, so as to provide insights into precise monitoring and control of hotspot colonization and risk areas of Pomacea snails. Methods Records of valid Pomacea snail presence in China from 2001 to 2024 were collected from the GBIF platform, and a descriptive statistical was performed using the software SPSS 26.0. In addition, publications regarding genetic tracing of Pomacea snails in China were systematically retrieved during the same study period, and population genetic structure and tracing evidence were extracted from publications to comprehensively examine their correlations. Results A total of 1 785 valid records were screened, covering 17 province-level administrative regions in China. The records were predominantly based on human observations (1 669 records, 93.50%), with a mean coordinate uncertainty of 70.42 m, indicating high spatial accuracy. The latitudes of valid records ranged from 18.298 967°N (Hainan) to 32.078 623°N (Jiangsu) and the longitudes ranged from 100.787 644°E (Yunnan) to 121.924 861°E (Taiwan), exhibiting a distribution pattern of a higher density in the southern region and a lower density in the northern region. Taiwan (1 435 records, 80.39%), Hunan (108 records, 6.05%), and Guangdong (85 records, 4.76%) emerged as the three primary hotspots for records. Temporally, a three-phase progression characteristic of “sporadic development” “slow initial growth” and “explosive growth” was found. From 2001 to 2010, a total of 4 records were documented; from 2011 to 2020, 503 records (an annual average of 50.3) were recorded. The record counts surged to 1 278 during the period between 2021 and 2024 (an annual average of 319.5), peaking in 2024 (386 records), with Taiwan as the primary contributor (364 records, 94.30%). A literature review of nine studies on genetic tracing revealed P. canaliculata as the overwhelmingly dominant Pomacea species in China, with origins traced to Argentina and Brazil in South America. Pomacea snail populations in Taiwan exhibited the most complicated genetic structure, while Pomacea snail populations from the lower reaches of the Yangtze River (Jiangsu and Shanghai) showed high genetic diversity (Hd = 0.627). In addition, some hotspots recorded in GBIF strongly coincided with areas with a high genetic diversity. Conclusion Some hotspots recorded in GBIF are spatially consistent with areas with a high genetic diversity of Pomacea snails. Taiwan serves as the core dispersal origin, while the lower reaches of the Yangtze River exhibit independent invasion events and a sustained northward expansion trend.
