研究了西太平洋两个古岩礁中发现的新生代介形虫。很大比例的分类群被限制在单个的小丘上,从而支持了最近的证据,即在这些水深隔离的地点记录的高度地方性是真实的,而不仅仅反映了对该地区缺乏了解。详细介绍了介形类组合的变化(多样性、丰度、优势度、特有性、动物群更替),并分析了恢复的主要类群的演变。由于特有分类群的高发生率,生物地层解释受到限制。然而,从这些介形类中出现的初步证据表明,介形类组合中的区域“事件”可以追溯到不同的岩礁上。
The Cenozoic Ostracoda recovered from two guyots in the western Pacific Ocean are investigated. A high percentage of the taxa have been restricted to the individual guyots, thus supporting recent evidence that high levels of endemism documented on these bathymetrically isolated sites are real and do not simply reflect lack of knowledge in that region. Changes in the Ostracoda assemblages (diversity, abundance, dominance, endemism, faunal turnover) are detailed, together with an analysis of the evolution of the major groups recovered. Biostratigraphical interpretatio ns are limited as a result of the high incidence of endemic taxa. Preliminary evidence is emerging from these Ostracoda, however, of regional "events" in the Ostracoda assemblages that can be traced on different guyots.
