项目摘要

The Late Cretaceous period of North America (~8566 million years ago) witnessed an explosion in the diversity of dinosaurs and other vertebrates (animals with backbones), followed by a decline in some groups leading up to the end-Cretaceous mass extinction that killed the non-avian dinosaurs. Biological processes, like niche partitioning (differential resource use), and environmental processes, like sea level and climate change, are among the factors that have been invoked to account for the rise and subsequent fall of this biodiversity. My research addresses these important issues using a threefold approach: (1) The identification of fossil species and their evolutionary relationships, (2) The placement of fossil species in the context of time and space, and (3) The study of past influences on fossil community structure and evolution. My research is collaborative in nature, and involves experts from throughout the world. It also presents Canadian students with the opportunity to do fieldwork in the classic badlands of Alberta, and to make innovative advancements in the disciplines of ecology and evolution. My research program has important implications for pressing conservation issues today, particularly those regarding long-term species coexistence and the effects of climate and sea-level change on biodiversity, which concern Canadians and the world at large.

北美洲白垩纪晚期（约 85.66 亿年前）见证了恐龙和其他脊椎动物（有脊椎的动物）多样性的爆炸式增长，随后一些群体的数量减少，最终导致白垩纪末期大规模灭绝，导致了恐龙和其他脊椎动物的灭绝。非鸟类恐龙。生态位划分（不同的资源利用）等生物过程和海平面和气候变化等环境过程是解释生物多样性兴衰的因素之一。我的研究使用三重方法解决这些重要问题：（1）化石物种的识别及其进化关系，（2）化石物种在时间和空间背景下的位置，以及（3）过去对人类的影响的研究化石群落结构和演化。我的研究本质上是协作性的，涉及来自世界各地的专家。它还为加拿大学生提供了在阿尔伯塔省经典荒地进行实地考察的机会，并在生态学和进化论领域取得创新进展。我的研究项目对当今紧迫的保护问题具有重要意义，特别是那些涉及长期物种共存以及气候和海平面变化对生物多样性的影响的问题，这些问题关系到加拿大人和全世界。
