Description and power analysis of two tests for detecting recent population bottlenecks from allele frequency data.
When a population experiences a reduction of its effective size, it generally develops a heterozygosity excess at selectively neutral loci, i.e., the proportion of loci with heterozygous excess is significantly larger than expected at mutation drift equilibrium. Expand
Computer note. BOTTLENECK: a computer program for detecting recent reductions in the effective size using allele frequency data
New methods employing multilocus genotypes to select or exclude populations as origins of individuals.
A new method for assigning individuals of unknown origin to populations, based on the genetic distance between individuals and populations, was compared to two existing methods based on the… Expand

BOTTLENECK: A Computer Program for Detecting Recent Reductions in the Effective Population Size Using Allele Frequency Data
BOTTLENECK (current version 1.2) is a population genetics computer program that conducts four tests for identifying populations that have recently experienced a severe reduction in effective… Expand
Estimating the probability of identity among genotypes in natural populations: cautions and guidelines
Individual identification using DNA fingerprinting methods is emerging as a critical tool in conservation genetics and molecular ecology. Statistical methods that estimate the probability of sampling… Expand

We use population genetics theory and computer simulations to demonstrate that population bottlenecks cause a characteristic mode-shift distortion in the distribution of allele frequencies at… Expand
Conservation and the genetics of populations

Landscape genetics: combining landscape ecology and population genetics
Understanding the processes and patterns of gene flow and local adaptation requires a detailed knowledge of how landscape characteristics structure populations. This understanding is crucial, not… Expand

The estimation of effective population size from one sample of genotypes has been problematic because most estimators have been proven imprecise or biased. We developed a web‐based program, onesamp… Expand
