AbstractDEB 0415277Marymegan DalyThis revision of the sea anemone subfamily Edwardsiinae (Cnidaria: Anthozoa: Actiniaria) addresses the diversity of one of the most speciose and poorly known groups of sea anemones. Edwardsines are burrowing anemones, and they inhabit some of the most threatened inshore habitats, including tidal marshes and mud flats; the pressures on these sensitive ecosystems has led to the documented decline of edwardsine populations in Australia, Ireland, the United Kingdom, and the United States. Elsewhere, edwardsines dominate macrofaunal communities, reaching densities of hundreds or thousands of individuals per square meter. Edwardsiinae is one of the few truly cosmopolitan groups of sea anemones, with all genera comprising species found in soft sediments at all depths in all oceans. The diversity and global distribution of edwardsines permits a variety of ecological, biogeographic, and evolutionary hypotheses to be examined, including: the correlations between habitat type and life history attributes, the relationship of polar and deep sea taxa, and evolution of burrowing. This project is the first such examination for any member of Actiniaria.The described diversity of Edwardsiinae centers on the North Atlantic, with a handful of species known from tropical and polar oceans. Because edwardsines are globally distributed and may be locally abundant, edwardsines are frequently collected during biodiversity surveys, oceanographic expeditions, and in ecological monitoring projects. Most specimens of Edwardsiinae in museum collections are unidentified, either because they belong to undescribed species or because identification is difficult, relying on attributes accessible only through histological examination. This project will document and describe species collected in the Pacific and Southern Oceans and re-evaluate the status of species from the North Atlantic and Arctic oceans, providing a comprehensive assessment of the biodiversity of Edwardsiinae. The establishment of identity for samples collected during faunal surveys and monitoring projects increases the value of such studies, and allows for more nuanced comparisons between sites. By describing species from under-studied regions and by producing electronic keys to the species of Edwardsiinae that facilitate identification by non-specialists, both bottlenecks in the identification of edwardsines are addressed.

摘要DEB 0415277Marymegan Daly 对海葵亚科 Edwardsiinae（刺胞动物门：Anthozoa：Actiniaria）的修订解决了最特殊且鲜为人知的海葵类群之一的多样性问题。 爱德华氏海葵是穴居海葵，它们栖息在一些最受威胁的近海栖息地，包括潮汐沼泽和泥滩；这些敏感生态系统所承受的压力已导致澳大利亚、爱尔兰、英国和美国的爱德华辛种群数量下降。 在其他地方，爱德华兹动物在大型动物群落中占主导地位，其密度达到每平方米数百或数千只。 爱德华氏海葵亚科是为数不多的真正世界性的海葵类群之一，其所有属均包含在所有海洋各个深度的软沉积物中发现的物种。 爱德华辛的多样性和全球分布允许对各种生态、生物地理学和进化假设进行检验，包括：栖息地类型和生活史属性之间的相关性、极地和深海类群的关系以及穴居进化。 该项目是对海葵属成员的首次此类检查。所描述的爱德华氏藻亚科多样性集中在北大西洋，其中有少数物种来自热带和极地海洋。 由于爱德华辛在全球分布，并且可能在当地丰富，因此在生物多样性调查、海洋探险和生态监测项目中经常收集爱德华辛。 博物馆收藏的大多数爱德华氏菌亚科标本都未经鉴定，要么是因为它们属于未描述的物种，要么是因为鉴定很难，依赖于只能通过组织学检查才能获得的属性。该项目将记录和描述在太平洋和南大洋收集的物种，并重新评估北大西洋和北冰洋物种的状况，从而对爱德华兹亚科生物多样性进行全面评估。 动物群调查和监测项目期间收集的样本的身份确定增加了此类研究的价值，并允许在地点之间进行更细致的比较。 通过描述来自未充分研究地区的物种并通过生成爱德华兹亚科物种的电子密钥以方便非专业人士识别，爱德华兹鉴定中的两个瓶颈都得到了解决。
