DNA-based methods for pedigree reconstruction and kinship analysis in natural populations
- M. Blouin
- 1 October 2003
The widespread use of microsatellite loci has spurred the recent development of many new statistical methods for inferring kin relationships from molecular data, which could extract far more pedigree information from natural populations than is currently being exploited. Expand
Use of microsatellite loci to classify individuals by relatedness
The simulation results accurately predict results one would obtain from this population in real life by scoring laboratory‐bred full‐ and half‐sib families whose parents were wild‐caught mice from the study population. Expand
Genetic Effects of Captive Breeding Cause a Rapid, Cumulative Fitness Decline in the Wild
The results suggest that even a few generations of domestication may have negative effects on natural reproduction in the wild and that the repeated use of captive-reared parents to supplement wild populations should be carefully reconsidered. Expand
Population structure of Columbia spotted frogs (Rana luteiventris) is strongly affected by the landscape
It is found that mountain Ridges and elevational differences were associated with increased genetic differentiation among sites, suggesting that gene flow is restricted by ridges and elevation in this species. Expand
Fitness of hatchery-reared salmonids in the wild
A simple quantitative genetic model is used to evaluate whether domestication selection is a sufficient explanation for some observed rapid fitness declines in hatchery fish in the wild, and it is shown that if selection acts on a single trait, such rapid effects can be explained only when selection is very strong.

Host movement and the genetic structure of populations of parasitic nematodes.
It appears that host movement is an important determinant of population genetic structure in these nematodes, and large effective population sizes appear to be the most likely explanation for high within-population diversities. Expand
Molecular prospecting for cryptic species of nematodes: mitochondrial DNA versus internal transcribed spacer.
- M. Blouin
- Biology, Medicine
- International journal for parasitology
- 1 May 2002
Mitochondrial sequence divergence was compared with divergence at mitochondrial cox1 or nad4 loci in pairs of congeneric nematode species, finding the difference being most striking in the most closely related species pairs. Expand
Molecular ecology of parasites: elucidating ecological and microevolutionary processes
We review studies that have used molecular markers to address ecological and microevolutionary processes in parasites. Our goal is to highlight areas of research that may be of particular interest in… Expand
A comparison between mitochondrial DNA and the ribosomal internal transcribed regions in prospecting for cryptic species of platyhelminth parasites
Analysis of mitochondrial DNA loci and ribosomal DNA internal transcribed spacers for their use in prospecting for cryptic species of platyhelminth parasites shows a higher level of divergence among species relative to intra-specific variation. Expand
Substitution bias, rapid saturation, and the use of mtDNA for nematode systematics.
- M. Blouin, C. Yowell, C. H. Courtney, J. Dame
- Medicine, Biology
- Molecular biology and evolution
- 1 December 1998
The usefulness of mtDNA for nematode phylogeny reconstruction is examined and data that can be used for a priori character weighting or for parameter specification in models of sequence evolution is provided. Expand
