武陵洞蛭模式产地的动物群落结构特征及其食物关系的初步研究
Preliminary Investigation of the Characteristics of Animal Community Structure and Food Relationships in the Type Locality of Sinospelaeobdella wulingensis
摘要
Abstract
Sinospelaeobdella wulingensis is a troglobite with special feeding habits.It is of a great signifi-cance to investigate the characteristics of animal community structure and food relationships in the type lo-cality(Shuiniu cave)of this species for cave ecobiology and conservation biology.From September 2022 to August 2023,monthly surveys on animal species and populations were conducted in the cave.The charac-teristics of animal community structure and the trophic level of S.wulingensis were analyzed using biodiver-sity indices and isotopic techniques.The main results were as follows:1)A total of 45 species of cave ani-mals were recorded,belonging to 42 genera,41 families,26 orders,15 classes and 6 phyla;2)The most common dominant species was Diestrammena caverna all around the year;3)The number of species and in-dividuals of cave animals had obvious differences between different light zones during the same period and within the same light zone across different periods;4)The Shannon-Wiener index and Margalef index in the dark zone were significantly higher than those in other light zones during the same period.The light zone exhibited a higher Pielou index but a lower Simpson index,while the weak light zone showed a higher Simp-son index but a lower Pielou index;5)Air humidity was the main meteorological factor affecting the popula-tion size of S.wlingensis;6)The natural enemies of S.wulingensis might be D.caverna,millipedes,Parobisium tiani and Porcellio scaber,with a trophic level of 3.05.This study provides foundational data for the further research on the evolutionary biology of leeches and the conservation of cave biodiversity.关键词
