About Kelle Freel

I'm currently a postdoc working at the Hawai'i Institute of Marine Biology with Dr. Mike Rappé. I'm interested in the biogeography and ecology of microbes, especially of the marine variety. After studying a unique genus of marine bacteria at Scripps Oceanography in grad school, I moved to France, where I worked with a group studying yeast population genomics. In my free time, I like to do outdoorsy stuff, travel, and cook.

When less might be more: The evolution of reduced genomes

Images courtesy of wiki commons The advent of affordable genome sequencing has provided us with a wealth of data. Researchers have sequenced everything from Escherichia coli (4.6 Mbp genome size), to sea urchins (810 Mbp), chimpanzees (3.3 Gbp), and humans (3.2 … Continue reading

Molecular adaptation in a deep-sea alien…*ahem* amphipod

Space: the final frontier…or is it? I was inspired Jeremy’s post yesterday to talk about that deep dark abyss that takes up the vast majority of our mostly blue planet. For the record, I’m in agreement with the assessments for the … Continue reading

Relatively rare tropical trees all agree: avoiding the ‘rain of death’ seems like a good call

When you think of a tropical jungle, what’s the first thing that comes to mind? Probably a lush green landscape with trees, vines, flowers, and let’s be real, at least one toucan. Tropical forests are made up of diverse groups … Continue reading

You can call her queen bee: the role of epigenetics in honeybee development

Insects have social lifestyles that are often organized in castes. Within the insect community, different individuals specialize, each having a unique role. This efficient method of doling out the workload, ultimately, is believed to be why social insect lifestyles are … Continue reading

A sponge and its symbionts, using genomics to unravel complex relationships

The ocean is full of interesting organisms and even more fascinating (as well as difficult to tease apart) are the interactions among them. From deep sea giant tube worms, to the adorable bobtail squid, symbioses have a central role, and … Continue reading

How much wood would a termite chuck…if it was missing its microbial symbionts

Termites get a pretty bad rap, probably because we think of our houses disintegrating when they move in. Ironically, we have a lot to learn from these critters, and their mounds have served as an inspiration for modern architecture. Either … Continue reading

Music to an amniote’s ears, an “accordion” model of genome size evolution

How did we get where we are? Genetically speaking, that is. A few posts ago, that whole genotype-phenotype question was discussed, how do genomes make plants and animals (and don’t forget the microbes!) look and act how they do. Another … Continue reading
