The study of the ecosystems in the survival and recovery time in the Early Triassic following the end-Permian mass extinction becomes a hotspot. It was also the leading topic at the International Symposium on Triassic Chronostratigraphy and Biotic Recovery held in Chaohu, Anhui Province from 23rd to 25th May 2005. All of the oral presentations are here summarized one by one and some key scientific subjects and the development in the field are abstracted. One of the key subjects reported at the symposium is the Early Triassic chronostratigraphy, esp. the GSSP for the Induan-Olenekian boundary; the second is the expression and process of biotic and environmental events during the Permian-Triassic transition; the third is the calcimicrobialite and the specific ecosystems at the Permian-Triassic boundary and in the Early Triassic; the fourth is the evolution and lineages of some key taxonomic groups in the Early Triassic; the fifth is the recovery process and pattern of the ecosystems at the beginning of the Mesozoic; and the sixth is the causes of the delayed biotic recovery in the Early Triassic.
