摘要

摘要:2017年3月至12月，在美国德克萨斯州的16个地点对有刺软壳龟(Apalone spinifera)、普通鳄龟(Chelydra serpentina)和红耳滑龟(Trachemys scripta elegans)进行了水蛭调查。共发现5种水蛭(15种刺麻3种，9种蛇形水蛭4种，55种细纹水蛭3种)，代表3个新的寄主记录和1个新的地方记录。通过主成分分析、逐步回归和模型选择，将水蛭丰度与水体参数(氨、二氧化碳、氯化物、溶解氧、硬度、亚硝酸盐、硝酸盐、pH、盐度、温度和浊度)和定性环境变量(植被、沉积物、纬度、经度、季节和水体)进行比较。我们发现沉积物组成和季节对水蛭丰度有显著影响。这项研究增加了关于德州水蛭寄主关联、分布和多样性的新数据。

Distribution and Diversity of Glossiphoniid Leeches on Three Common Species of Freshwater Turtles from Texas, U.S.A.

abstract: Spiny softshell turtles (Apalone spinifera), common snapping turtles (Chelydra serpentina), and red-eared sliders (Trachemys scripta elegans) were surveyed for leeches at 16 sites across Texas, U.S.A., from March to December of 2017. Five species of leeches were found (3 from 15 A. spinifera sampled, 4 from 9 C. serpentina sampled, and 3 from 55 T. scripta elegans), representing 3 new host records and 1 new locality record. Leech abundance was also compared to water parameters (ammonia, carbon dioxide, chloride, dissolved oxygen, hardness, nitrite, nitrate, pH, salinity, temperature, and turbidity) and qualitative environmental variables (vegetation, sediment, latitude, longitude, season, and water body) through principle components analysis, stepwise regression, and model selection. We found significant effects of sediment composition and seasonality on leech abundance. This study adds novel data on leech–host associations, distributions, and diversity in Texas.

期刊介绍： Comparative Parasitology (continuing the Journal of the Helminthological Society of Washington in its 67th volume) focuses on parasitological research of a comparative nature, emphasizing taxonomy, systematics, ecology, biogeography, evolution, faunal survey, and biological inventory within a morphological and/or molecular context. The scope of Comparative Parasitology extends to all parasitic faunas, including helminths, protistans and arthropods.
