An evolutionary cycle …

Rescan, Lenormand and Roze (2016) recently published new models on the evolution of life cycles in The American Naturalist. Most animals and protists have diploid life cycles in which the haploid stage is reduced to a single-celled gamete. Other organisms, such … Continue reading

An Oedipus complex in mosses?

Nannandrous … phyllodioicous … gotta love botanical terms and these will most definitely find their way into this week’s list of favorite words! Both refer to the tiny epiphytic nature of males situated on much larger female shoots. There may be many … 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

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

Just like an elephant and a manatee …

There is a positive correlation between the time since two lineages have diverged and the strength of the reproductive barriers between them. Rothfels et al. (2015) have described a natural hybridization event between two fern genera that diverged from one … Continue reading
