Extinction of island endemics: it is not inbreeding depression

It Is Not worth Learning If It Is Not Remembered:

The collation, storage and retrieval of information are essential components of successful learning. Whether information is retained depends on a variety of factors, including how the information fits with an individual’s existing knowledge, the way in which information is presented, and its complexity. Some of these factors are under the direct control of the e-learning designers and developer...

Inbreeding Depression Is Purged in the Invasive Insect Harmonia axyridis

Bottlenecks in population size reduce genetic diversity and increase inbreeding, which can lead to inbreeding depression. It is thus puzzling how introduced species, which typically pass through bottlenecks, become such successful invaders. However, under certain theoretical conditions, bottlenecks of intermediate size can actually purge the alleles that cause inbreeding depression. Although th...

Detecting inbreeding depression is difficult in captive endangered species

During the past two decades, pedigree analysis has documented inbreeding depression in many captive populations. This and subsequent research has led to a recognition that inbreeding depression is a potentially important determinate of small population fitness, in both captivity and the wild. Modern captive-breeding programmes now universally avoid inbreeding. We use simulation to investigate h...
