REVSYS: Systematic revision of onchidiid slugs (Mollusca, Gastropoda, Pulmonata)

本计画将对螺类（软体动物门、腹足类、肺螺类）进行系统学分析，并修正分类。在腹足类动物中，有着独特的生态多样性，包括生活在海洋、淡水和陆地上的物种。因此，对Onchidiidae的研究将为该项目提供一个独特的机会，以研究水生和陆生栖息地之间以及密切相关的物种之间的一般进化过渡。总的物种多样性和分布是目前未知的（147种已被描述在世界各地，其中大部分在热带印度-西太平洋），并将在这里记录一个新的分类修订的基础上形态和分子数据。实地考察将为系统和生态分析提供新的材料。研究结果将以论文和专题修订版以及分类鉴定检索表的形式发表。研究和教育将通过一系列涉及主办机构本科生的创新活动进行整合。一名博士生和至少两名本科生将接受野外采集、解剖解剖、扫描电子显微镜、分子系统学和分类学理论问题的培训。增强的onchidid系统学将有利于不同领域的科学家-例如，生理学家使用onchidids作为模型来研究感光性，保护生物学家使用onchidid slu作为严重威胁的沿海栖息地的多样性和生态的关键指标。

This project will analyze the systematics and revise the taxonomy of onchidiid slugs (Mollusca, Gastropoda, Pulmonata). Onchidiid slugs are unique within gastropods for their ecological diversity - including species that live in the sea, fresh water, and on land. As such, research on Onchidiidae will provide a unique opportunity for this project to study general evolutionary transitions between aquatic and terrestrial habitats and between closely related species. Total species diversity and distribution are currently unknown (147 species have been described worldwide, most of which in the tropical Indo-West Pacific), and will be documented here with a new taxonomic revision based on both morphological and molecular data. Field expeditions will provide fresh material for systematic and ecological analyses. Results will be published as articles and monographic revisions, as well as taxonomic identification keys.Research and education will be integrated through a series of innovative activities involving undergraduate students from the host institution. One PhD student and at least two undergraduate students will be trained in field collecting, anatomical dissection, Scanning Electron Microscopy, molecular systematics, and theoretical issues in taxonomy. Enhanced onchidiid systematics will be beneficial to scientists from different fields - for example, physiologists using onchidiids as a model to study photoreception, and conservation biologists using onchidiid slugs as a keystone indicator of the diversity and ecology of heavily-threatened coastal habitats.
