Journal ArticleDOI
One hundred years of eruptions of house mice in Australia: a natural biological curio
TL;DR: The house mouse has adapted well to the cereal crops of south-eastern Australia where populations show aperiodic outbreaks over large areas where a reduced diversity of diseases partially accounts for the ability of mice to increase rapidly to extreme population densities.
Journal ArticleDOI
Europe-wide dampening of population cycles in keystone herbivores

TL;DR: Using a large compilation of time series of vole abundances, it is demonstrated consistent cycle amplitude dampening associated with a reduction in winter population growth, although regulatory processes responsible for cyclicity have not been lost.
Journal ArticleDOI
The Puzzles of Population Cycles and Outbreaks of Small Mammals Solved
TL;DR: This work synthesizes the recent knowledge of three key aspects of these animals' population cyles: periodicity, amplitude, and spatiotemporal synchrony; (2) reproduction and survival; and (3) underlying mechanisms.
Journal ArticleDOI
Microhabitat use, giving-up densities and temporal activity as short- and long-term anti-predator behaviors in common voles
Jens Jacob,Joel S. Brown +1 more
TL;DR: Microhabitat differences in GUDs reflect short-term strategies of predator avoidance and the trapping data reflect long-term patterns of anti-predator behavior, which suggests that predators are more abundant or effective in the mowed grass at night and in the unmowed grass during the day.
