The evolutionary palaeoecology of species and the tragedy of the commons
PD Roopnarine, KD Angielczyk - Biology Letters, 2012 - royalsocietypublishing.org
The fossil record presents palaeoecological patterns of rise and fall on multiple scales of
time and biological organization. Here, we argue that the rise and fall of species can result …

Confidence intervals for the duration of a mass extinction
SC Wang, AE Zimmerman, BS McVeigh, PJ Everson… - Paleobiology, 2012 - cambridge.org
