During the last decade, we developed ground beetles (Coleoptera: Carabidae) as a new paleoenvironmental proxy in high mountains of low latitudes. We showed that the combination of ecological and phylogenetic information from species groups endemic to the Himalayan-Tibetan orogeny (HTO) allows for the development of scenarios of the spatio-temporal evolution of paleoenvironments and thus, for regional surface uplift in the HTO. To understand the environmental evolution of the central part of the HTO, the Tibetan Plateau (TP), information about timing of trans-Tibet distribution events in wingless ground beetle species groups are particularly informative. The detailed phylogenetic study of these species-groups in combination with a fossil based molecular clock approach and investigation of the habitat preferences of the species will indicate timing of the development of high montane and alpine environments on the TP. The here proposed study will thus provide new data and insight for a better understanding of the paleoecology and paleotopography of the HTO during different stages of orogenesis.

近十年来，我们在低纬度的高山地区发现了一种新的古环境代用品——地甲虫（鞘翅目：甲虫科）。对这些类群进行详细的系统发育研究，结合基于化石的分子钟方法和物种栖息地偏好的调查，将揭示青藏高原高山地和高山环境发育的时间。本文的研究将为更好地认识HTO不同造山阶段的古生态和古地形提供新的数据和见解。
