Relicts from Tertiary Australasia: undescribed families and subfamilies of songbirds (Passeriformes) and their zoogeographic signal.
A number of hitherto unrecognized, deeply divergent taxa of Australasian songbirds have been revealed by DNA sequence studies in the last decade. Differentiation among them is at levels equivalent to family and subfamily rank among songbirds generally. Accordingly, the purpose of this paper is to name and describe eleven of them formally under Articles 13.1, 13.2, 16.1 and 16.2 of the Internati...

We live in a technology driven society where, each one of us continuously leaves digital traces behind. Our mobile phones, for example, continuously sense our movements and interactions. This sociogeographic data could be continuously captured by millions of people around the world and promises to reveal important behavioral clues about humans. Mining patterns of human behavior from large-scale...

متن کاملTallgrass Prairie: Remnants and Relicts
The tallgrass prairie once was continuous throughout the eastern Great Plains. Now, scattered remnants remain. The distribution of some of the most interesting and socially valuable remnants occur along the base of the Rocky Mountains as relicts from a past era. When the species composition of these Colorado grasslands is compared with that of the eastern tallgrass prairie by an index of simila...
متن کاملYoung relicts and old relicts: a novel palaeoendemic vertebrate from the Australian Central Uplands
Climatic change, and in particular aridification, has played a dominant role in shaping Southern Hemisphere biotas since the mid-Neogene. In Australia, ancient and geologically stable ranges within the vast arid zone have functioned as refugia for populations of mesic taxa extirpated from surrounding areas, yet the extent to which relicts may be linked to major aridification events before or af...
