Phylogenetic Systematics of North American Fossil Caninae

9707555泰德福德犬科动物是犬科动物中现存的一员，由一群形形色色的捕食者(狐狸、野狼、狼、猎犬和家犬)组成，它们属于犬亚科。狗的家族包括另外两个亚科(Hespercyoninae和Borophahinae)，这两个亚科都已经灭绝。美国自然历史博物馆的特德福德和王将对北美犬科化石的系统发育关系和生物地层学进行全面研究，这是他们对犬科动物从始新世晚期(约4000万年前)到现在的长期、高分辨率研究的最后一章。他们将从化石和现存的犬类中获取形态数据，并将利用最近可用的分子系统学来描述新的分类群，并记录犬类的多样性、生物年代学和动物地理学。这项研究的材料将来自几个哺乳动物化石收藏，包括美国博物馆全面的查尔兹·弗里克收藏。该项目彻底描绘了北美卡尼亚族的历史，并对其来往于其他大陆的复杂运动进行了分析和记录。该项目还将建立一个数据库，以便对包括地质演替、功能形态和对短期和长期环境变化的反应在内的许多主题进行调查。

9707555 Tedford The living members of the dog family (Canidae) consist of a diverse group of predators (foxes, jackals, wolves, hunting dogs, and domestic dogs) that belong to a closely knit group, the subfamily Caninae. The dog family includes two other subfamilies (Hesperocyoninae and Borophahinae), both of which are extinct. Tedford and Wang of the American Museum of Natural History will undertake a comprehensive study of the phylogenetic relationships and biostratigraphy of North American fossil canines as the final chapter of their long-term, high-resolution study of the evolution of the family Canidae from the late Eocene (roughly 40 million years ago) until present. They will acquire morphological data from both fossil and extant canines and will utilize recently-available molecular phylogenies to describe new taxa and to document canine diversity, biochronology, and zoogeography. The material for the study will come from several collections of fossil mammals, including the comprehensive Childs Frick Collection at the American Museum. The project thoroughly delineates the history of Caninae in North America and permits analysis and documentation of their complex movements to and from other continents. The project also will engender a database that will allow investigation of a number of topics including geological succession, functional morphology, and response to short and long-term environmental change.
