摘要

2014年3月至2016年2月，采用0.5 mm网目对Teesta河malacofauna进行了调查。共报道7科9种。所有这些物种都属于最不关注(LC)类别。在Teesta河也报道了一种入侵物种Physellaacuta。在这9个物种中，有7个是可食用的软体动物。利用PAST软件进行多样性指数和主成分分析。分类群数、优势度指数、Shannon多样性指数、均匀度指数和Margalef丰富度指数分别为3 ~ 7、0.123 ~ 0.50、0.868 ~ 2.149、0.5659 ~ 0.9531和0.8049 ~ 2.25。Shannon多样性指数和均匀度指数在季风季节最大，在冬季最小。

Diversity and conservation status of malacofauna from the river Teesta,West Bengal, India

A survey on malacofauna in the river Teesta from March 2014 to February 2016 was done by using caste net of mesh size 0.5 mm. A total of 9 species belonging to 7 families were reported. All thesespecies are under Least Concern (LC) category. One invasive species Physellaacuta also reported from the river Teesta. Of the 9 species, 7 are edible molluscs. Diversity indices and PCA were done by PAST software. Number of taxa, dominance index, Shannon diversity index, evenness index and Margalef’s richness index were ranged from3-7, 0.123-0.50, 0.868-2.149, 0.5659-0.9531 and 0.8049-2.25respectively. Shannon diversity index and evenness index were maximum during monsoon and minimum during winter season.

期刊介绍： The AJCB publishes important new ideas and findings that have general implications for the scientific basis of conservation of plants and animals. It includes research papers, reports, comments, subject reviews, and book reviews in the following subjects: -biodiversity -population biology -evolutionary ecology -conservation genetics -conservation biogeography -natural history -conservation economics -conservation management practices -epidemiology -freshwater and marine biology -GIS/spatial analysis in conservation planning The AJCB is essential reading for conservation biologists, policy-makers and students.
