Linking gene expression and phenotype in an emerging model organism
Last week in his post “Transcriptomics in the wild (populations),” TME contributor Noah Snyder-Mackler focused on a recent paper by Alvarez et al. that reviews the last decade of transcriptomic research including the goal of linking gene expression and phenotype. Researchers today routinely collect transcriptomic data for non-model … Continue reading

Rejection, Academics, and Success.
With the holiday season in full swing, I thought that I share a link to a recent post on weathering the rejection storm that almost invariably accompanies grant and publication reviews. those of you getting rejections are in great company. … Continue reading

haploidy, diploidy, polyploidy … not a problem
Investigating pairwise relatedness is fundamental to the characterization of the mating system and inferring genetic structure. If no pedigree exists, then relatedness is estimated from genetic markers (e.g., microsatellite loci) using method-of-moment or maximum-likelihood methods. However, not all individuals in … Continue reading
Sweeping for Sweeps
Reduction in genomic diversity around a site has been attributed to one of two mechanisms – (1) sites linked to positively selected mutant alleles are often `swept’ to fixation, in a process often called genetic hitchhiking, and/or (2) background selection … Continue reading

A molecular how-to for hibernating this winter
As the academic semester ends, I see the tell-tale signs of the upcoming holiday hibernation. The weary eyes of teaching assistants peeking over piles of final exams. Students who may have mentally been on break before finals even started. A little … Continue reading
This post is for the birds
Note: this post was has been corrected to reflect the fact that Flamingoes and Pigeons are not sister species, but members of sister clades. Darwin’s favorite bird, the pigeon, has a new sister (clade) that includes Flamingoes and Grebes. This … Continue reading

LSUMNS researchers are at the top of the list for new species discoveries in 2014
2014 was an exciting year for describing new biodiversity for researchers at the Louisiana State University Museum of Natural Science (LSUMNS). Top ten lists are ubiquitous this time of year and two such lists documenting the top new species of 2014 … Continue reading

Identifying and correcting errors in draft genomes
Over the past decade we have seen an exponential increase in the number of sequenced, assembled, and annotated genomes. These these genomes are essential for pretty much any genomics research. If you want to sequence the genome, transcriptome, epigenome, or … Continue reading

Exotic gene flow surveillance
Exotic forest plantations often cover large areas and, as such, may contribute female gametes, male gametes and/or zygotes to native stands. In seed plants, these three components of exotic gene flow have not been distinguished, though they will have different … Continue reading
