In the northern biosphere

As regular readers will know, I’ve spent the summer traveling around the Northern Hemisphere sampling the red seaweed Gracilaria vermiculophylla, an introduced alga in North America and Europe. I’ve rewound to the beginning of the summer in order to highlight our … Continue reading

Dōmo arigatō

Along with my collaborators, Erik Sotka, Courtney Murren, Allan Strand and our battery of students, we have embarked on an intense summer field season. Erik and I are leading the effort of sampling populations of the introduced red seaweed Gracilaria … Continue reading

Clonal conundrum, part deux

In the second installment of the clonal conundrum, one hallmark of clonality is one that surprisingly hasn’t been validated that many times using species that have both sexually and asexually reproducing populations. Theoretically, clonal reproduction should generate massive … Heterozygote excess … Continue reading

Clonal conundrum, part un

Molecular ecologists are faced with a clonal conundrum when we wish to investigate the evolutionary ecology of clonal organisms. An attack of the clones is not something that should frighten one away …

Haploid-diploidy, a (brief?) history

Haploid-diploid life cycles are not only good exercise for the brain, but they’re also fantastic study systems to investigate a myriad of questions. Yet, the majority of molecular studies have focused on the diploid-dominated life cycles of animal and plant … Continue reading
