Abstract

ABSTRACT Substrate variety and host preference of the epizoic limpet Lottia tenuisculpta were investigated based on specimen and field observations. Specimen observation revealed the presence of the limpet on 33 species of Mollusca and two species of Crustacea, and it predominantly used Tegulidae and Muricidae throughout its geographic range. Some of the substrate molluscs had radula traces and home scars probably engraved by L. tenuisculpta. Field observations conducted on the rocky shore of Shirahama, Wakayama, Japan, revealed the presence of L. tenuisculpta on 12 species of molluscs. The tegulid Omphalius nigerrimus and the muricid Reishia clavigera were its major substrates in the locality. The results of both sets of observations suggest that L. tenuisculpta is a host-general facultative epizoite and its host preference is family-specific. The choice of host species by L. tenuisculpta might be determined by the abundance and morphological and biological restrictions of the preferred substrates in each locality. The host-general and facultative nature of the limpet allows it to show geographical host conversion and contribute to favouring epizoic behaviour. Home scars of L. tenuisculpta on the hosts suggest that the limpet inhabits the same individual of the substrate species for an extended period.

表生界帽贝Lottia tenisculpta的基质多样性和寄主偏好（帕特洛腹足目：Lottidae）

摘要基于标本和野外观察，研究了狭棱棱贝(Lottia tenuisculpta)的基质多样性和寄主偏好。标本观察发现，帽贝生活在33种软体动物和2种甲壳类动物上，在其地理分布范围内，帽贝主要生活在Tegulidae和Muricidae。部分底栖软体动物有斑纹痕迹和家痕，可能为细纹乳藻所刻。在日本和歌山市白滨的岩石海岸进行的野外观察发现，在12种软体动物身上存在L. tenuisculpta。其在当地的主要底物为杀菌剂黑线虫和杀虫雷氏菌。这两组观察结果表明，L. tenuisculpta是一种寄主-一般兼性辉长石，其寄主偏好具有科特异性。柽柳寄主的选择可能是由每个地区的首选底物的丰度和形态和生物学限制决定的。帽贝的宿主-一般和兼性性质使其能够显示地理宿主转换，并有利于动物行为。帽贝在寄主上的家痕表明，帽贝长期居住在同一底物物种的个体上。

期刊介绍： Molluscan Research is an international journal for the publication of authoritative papers and review articles on all aspects of molluscan research, including biology, systematics, morphology, physiology, ecology, conservation, biogeography, genetics, molecular biology and palaeontology. While the scope of the journal is worldwide, there is emphasis on studies relating to Australasia and the Indo-west Pacific, including East and South East Asia. The journal’s scope includes revisionary papers, monographs, reviews, theoretical papers and briefer communications. Monographic studies of up to 73 printed pages may also be considered. The journal has been published since 1957 (as the Journal of the Malacological Society of Australia until 1993). It is free to members of the Malacological Society of Australasia and the Society for the Study of Molluscan Diversity.
