摘要：生物多樣性並不是一成不變的，而是在長久的生命歷史中不斷的演變，經歷了長期以來不論是隨著環境的變遷或是物種間相互的捕獵或共存，而到了我們現階段所觀察到的生物多樣性。透過從不同的地質時間點所發現的化石，我們可以清楚地觀察到生物多樣性的演變，不論是新物種的崛起或是當地物種或族群的滅絕等。由於脊椎動物較大的體型，脊椎動物在了解生態及演化歷史中都佔有了一定的角色，此研究計畫也將試著解開台灣及其周圍海域現生脊椎動物多樣性（包含了水生及陸生）的起源。為了要了解現生脊椎動物多樣性的起源，本研究將集中於描述在地質時間中近五百萬年（上新世和更新世，如果也有發現的話，也不排除超過五百萬年前的中新世化石）脊椎動物化石的分布及動物群隨著時間演變的狀況。在台灣及周圍海域所出現的上新世及更新世的脊椎動物化石並不算少，但是很大一部分缺少了系統性的科學辨識及描述阻礙了我們對於過去物種多樣性演變過程的全面性的理解，也造成了我們對於現生脊椎動物多樣性的起源並不夠透徹。在這研究計畫中，我將正式地描述過往生活在台灣及其周圍海域的脊椎動物，將其研究發表到國際性的期刊，讓我們對於在台灣及周圍海域脊椎動物的起源及演變有更完整的了解。
Abstract: Biodiversity is not unchangeable, but constantly evolving along the long history of Life. The current biodiversity that we are observing today is coming from a longterm result of both environmental change and/or interactions among diverse species. By uncovering fossils from different geological periods, we could clearly read the evolution of biodiversity, both resulting from the rise of new species or the demise of local species/populations. This proposal aims to unfold the origin of modern vertebrate diversity (including aquatic and terrestrial), which plays critical ecological and evolutionary roles due to their large body sizes, in Taiwan and its surrounding waters. In order to understand the origin of modern vertebrate diversity, this study would focus on describing the occurrence and the turnover along the geological time-line of fossil vertebrates in the past five million years (i.e. Pliocene and Pleistocene, but not excluding fossil vertebrates from the Miocene if found). Fossil vertebrates from the Pliocene and Pleistocene are not uncommon in Taiwan and its surroundings, but mostly lack of proper and updated scientific identification and description systematically hinders a full understanding of the faunal turnover in the past leading to the emergence of modern vertebrate diversity. During the course of this research proposal, I will be officially describing remains of vertebrates lived in the past of Taiwan and surrounding waters, publishing research papers in the international journals, and then shedding new light on the origin and faunal succession of vertebrate diversity in and around Taiwan.
