The geographic distribution of life on Earth supports a general pattern of increase in biodiversity with increasing temperature. However, some previous analyses of the 540-million-year Phanerozoic fossil record found a contrary relationship, with paleodiversity declining when the planet warms. These contradictory findings are hard to reconcile theoretically. We analyze marine invertebrate biodi...

An experiment was designed to test whether different individuals produce similar voice patterns when they read the same emotional passage. Quantitative scoring criteria were developed that reflect the extent to which different individuals consistently produce similar constellations of acoustic attributes in response to the same emotional context. The scoring procedure was applied to the voice t...

Cities in North America have been building bicycle infrastructure, in particular cycle tracks, with the intention of promoting urban cycling and improving cyclist safety. These facilities have been built and expanded but very little research has been done to investigate the safety impacts of cycle tracks, in particular at intersections, where cyclists interact with turning motor-vehicles. Some ...
