1. Fine sediment habitats in southwestern coastal waters seem favor the presence of high species richness and great abundance of individuals but moderate diversity of the brachyuran crab community.

台湾西南近海海域的细沙海底，似乎有利高物种种类数与丰富量的存在，但物种歧异度则属中等。

2. Local distribution patterns and diversity of brachyuran crabs in subtidal soft-bottom habitats of Taiwan were studied from August 1994 to July 1995.

摘要本研究于1994年8月至1995年7月间，进行了台湾亚潮带软质海底栖地之螃蟹区域分布模式与物种歧异度的调查。

3. Patterns and processes of brachyuran crab settlement to Caribbean coral reefs.

新竹香山潮间带的螃蟹。

4. The brachyuran crab community in the deepest sampling station (NFA) had the lowest diversity and least similar in community structure to other sampling stations.

最深采样区（宜兰南方澳）之物种种类数最低，与其他调查区之物种歧异度的相似度亦最低。

5. We determined the mitochondrial DNA sequence of S. yangtsekiense and discussed the phylogenetic status of freshwater crabs in Brachyuran according to gene arrangement features and sequence data sets.

本文以长江华溪蟹为代表，通过对线粒体基因组序列的测定，从基因序列和排列顺序2个方面探讨淡水蟹类在短尾类中的系统地位；

6. Depth and particle size were primary and secondary environment variables that influence the community structure of brachyuran crabs in the present geographic region.

深度与沙粒粒径大小，分别为影响调查区域内螃蟹群聚结构之主要与次要因素。
