An evolutionary cycle …

Posted on 15 Jan, 2016 by Stacy Krueger-Hadfield

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 →

Best laid plans of algae and academics oft go astray

Posted on 4 Dec, 2015 by Stacy Krueger-Hadfield

When you’re stuck in R and feel some procrastination is in order … write another travelogue post! I’ve wanted to spin some yarns about field mishaps. There’s no way we could sample over 45 sites without something going wrong. For our Northeast … Continue reading →
