Best laid plans are probably not best laid … As I mentioned before, I had every intention of writing up posts on interesting papers as well as highlighting the hosts gracious enough to house/feed/guide us around this summer. Alas, time … Continue reading

marmap
A couple years ago, Benoit Simon-Bouhet ended up sharing an office with Eric Pante, then a post-doc fellow in his former lab. The two quickly realized they were in a lab in which few people had the expertise or taste for coding. Thus, on … 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

A cladoceran invasion
My posts are about to take on a strong bias towards field work and interviews with the researchers kind enough to offer assistance to our lab as we embark on a Northern Hemisphere tour. Not only will we be sampling seaweeds … Continue reading

Easy as ABC
Determining the whens and hows of biological invasions using genetic data is a major goal of molecular ecology. One such tool is approximate Bayesian computation (ABC) which is being used for inferring invasion histories. In a new paper in Heredity, Benazzo et … Continue reading

When genomes duplicate
Whole genome duplication events have played an important role in the evolutionary history of plants. Vallejo-Marín et al. (2015) describe origins of a new polyploid species, Mimulus peregrines, found on the Scottish mainland as well as the Orkney Islands. It was formed within … Continue reading

Grasping gorgonians
A recent issue of Heredity focused on the brave new world of environmental genomics. After highlighting the special issue, I started chatting to one of the contributors, Eric Pante and became interested in his work on gorgonians. Eric and his co-authors explored the … 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 …
