Minor extinction events occurred sporadically throughout the Cambrian Period.

This would have made pterosaur diversities specialised, and thus vulnerable to minor extinction events.

Last year's paper by Kirchner and a colleague, showing it takes 10 million years for biodiversity to be renewed following an extinction event Commentary by Douglas Erwin on that paper Milwaukee Public Museum's Geologic Time Scale Diversity Through Time graphic based on Sepkoski's work Cycles of mass and minor extinctions on Earth, from the Hooper Virtual Paleontological Museum.

Optical microscopy of these particles shows minor undulatory extinction of olivine and plagioclase, suggesting minor shock metamorphism (shock stage: S2).

All these particles show minor undulatory extinction of olivine and plagioclase, and the estimated shock stage is S2.

An epidemic starting with one index case in a completely susceptible population without intervention grows exponentially, if it survives early extinction (minor epidemics).

Moreover, there seems to be a link between the number of originations and extinctions, although not within one time interval but rather with a minor delay of the extinction curve.

It was the pioneering work of Dr. J.

Here we show that evolution of sex-specific dispersal could enhance persistence of hosts that experience infection by male-killing endosymbionts in two different ways: (i) by decreasing host extinction probabilities (minor effect) and (ii) by inducing curing of the host (major effect) through the combined action of increased male and decreased female dispersal.

In order to more specifically identify factors influencing the proportion of minor epidemics (accounting for early extinction) we also calculate partial rank correlation coefficients (PRCC) for this variable.
