项目摘要

Habitat destruction, environmental change, and invasive species are causing the extinction of species faster than scientists can find and record them. Of all the major animal groups, snails have the highest extinction rates, and most of these losses have occurred in the Pacific islands. Hawaii, a diversity hotspot, supports one of the world's most spectacular land snail radiations with more than 750 species and numerous species still unknown to science. However, the number of species is declining rapidly, and extinction estimates are already 50% or more. The Oahu Tree Snails (Achatinellidae) are the most diverse and iconic snails in the Hawaiian Islands. Research on these snails has contributed to development of evolutionary theory and island biology, yet basics about the biology and diversity of the group is still lacking. This project uses morphological, molecular, and biogeographic data from museum and recently collected specimens to clarify the taxonomy of this important land snail family, and provide insights into their evolution and conservation. Accurate and updated understanding of the identities and relationships of these snails is critical to the welfare of the ecosystem. Training will be integrated throughout this project, ensuring the development of the next generation of scientists.The project will assess the systematics of the highly threatened and iconic Achatinellidae, providing a revised and updated classification that will be the foundation for a better understanding of their diversification and conservation. The project will provide training for one postdoctoral researcher, one Ph.D. student, and numerous university undergraduates and high schoolers while addressing the three primary research objectives: 1) produce revised and updated subfamily and generic monographs of the Hawaiian Achatinellidae, including descriptions of 13 new species; 2) develop the first comprehensive, Pacific-wide phylogenetic hypothesis for the Achatinellidae using a modern morphological and molecular approach; 3) assess the biogeographic history of the Hawaiian Achatinellidae and their conservation. High school, undergraduate and graduate students from underrepresented groups in STEM will learn a range of techniques from molecular phylogenetics to anatomical analyses and museum curation and digitization, thereby linking science education with hands-on research, while growing and sustaining essential expertise in taxonomy. Trainees will be heavily involved in development of web-based products providing biogeographic, ecological and taxonomic data for each species, accessible to researchers and the public, and used to develop museum exhibits for broader access.

栖息地破坏，环境变化和入侵物种正在使物种的灭绝速度比科学家所能找到的要快，并记录下来。在所有主要动物群体中，蜗牛的灭绝率最高，其中大多数损失发生在太平洋岛屿。多样性热点夏威夷支持世界上最壮观的土地蜗牛辐射之一，其中有750多种，并且许多物种仍然不知道科学。但是，物种数量正在迅速下降，灭绝估计已经为50％或更高。瓦胡岛蜗牛（Achatinellidae）是夏威夷群岛上最多样化和标志性的蜗牛。这些蜗牛的研究有助于发展进化论和岛屿生物学，但仍缺乏有关该群体的生物学和多样性的基础知识。该项目使用博物馆的形态，分子和生物地理数据，并最近收集了标本来阐明这个重要的土地蜗牛家族的分类学，并为其进化和保护提供了见解。对这些蜗牛的身份和关系的准确和更新的理解对于生态系统的福利至关重要。培训将在整个项目中整合，确保下一代科学家的发展。该项目将评估受威胁和标志性的Achatinellidae的系统学，提供经过修订和更新的分类，这将是对他们的多元化和保护的更好理解的基础。该项目将为一位博士学位博士提供培训。学生和众多大学的本科生和高中生在解决三个主要研究目标的同时：1）生产夏威夷achatinellidae的修订和更新的亚科和通用专着，包括13种新物种的描述； 2）使用现代的形态学和分子方法为Achatinellidae开发了第一个全面的，太平洋范围的系统发育假设； 3）评估夏威夷achatinellidae及其保护的生物地理历史。 STEM中代表性不足的群体的高中，本科生和研究生将学习从分子系统发育学到解剖学分析以及博物馆的策划和数字化的一系列技术，从而将科学教育与动手研究联系起来，同时在分类学领域成长和维持基本的专业知识。受训者将大量参与基于网络的产品的开发，为每个物种提供生物地理，生态和分类数据，可供研究人员和公众访问，并用于开发博物馆展览以进行更广泛的访问。
