Taxonomy of Careproctus (Liparidedae, Pisces) of the Southern Ocean

鲤科是一个广泛分布于北半球和南半球温带和寒冷水域的底栖分类群。最近的研究表明，南大洋的物种数量可能与白令海一样多，白令海以前被认为是物种多样性最高的地区和主要分布中心。Liparidids可能是南大洋物种最丰富的科，这与传统的观点相反，认为南方特有的Nototheniidae科是最丰富的科。属中种类最丰富的是Careproctus，深度最广，可达50 ~ 7200米。它包括大约18个未被描述的南极物种，是唯一一个最近没有被分类审查的南大洋脂类。拟议研究的直接目标是鉴定、描述和重新描述发生在南大洋的Careproctus物种。标准的分类学方法将被使用，但重点将是在liparidid属中寻找以前未使用的独特特征。对南极所有鱼类的识别和描述将有助于更好地了解南极鱼类动物的动物地理和历史，将南极鱼类动物与白令海的动物进行比较，并有助于解释该科为何以及如何实现其两极分布和高物种多样性。准确的物种描述将有助于研究南极鱼类在适应深海生物过程中发生的变化、南大洋及其邻近水域的生态以及南极鱼类的分布和动物地理。

The fish family Liparididae is a widely distributed, benthic taxon in temperate and cold waters of the Northern and Southern Hemispheres. Recent studies show that there may be as many species in the Southern Ocean as in the Bering Sea, previously considered an area of highest species diversity and primary center of distribution. Liparidids are probably the most species-rich family in the Southern Ocean, contrary to the traditional view giving this position to the endemic southern family Nototheniidae. The most species-rich liparidid genus is Careproctus, which has the broadest depth range of 50 to 7200 m. It includes about 18 undescribed Antarctic species and is the only group of the Southern Ocean liparidids not recently reviewed taxonomically. The immediate goals of the proposed research are the identification, description and redescription of Careproctus species occurring in the Southern Ocean. Standard taxonomic methods will be used, but emphasis will be on a search for previously unused distintive characters in the liparidid genus. The identification and description of all Antarctic liparidids will permit studies leading to better understanding of the zoogeography and history of the Antarctic ichthyofauna, comparison of the Antaractic liparidid fauna with that of the Bering Sea, and may help explain why and how the family achieved its bi-polar distribution and high species diversity. Accurate species descriptions will be of great assistance in studying the changes which occur during adaptation to deep-sea life, the ecology of the Southern Ocean and adjacent waters, and the distribution and zoogeography of Antarctic fishes.
