Dear Sponge – I Am Breaking Up With You

To help us understand the complexities of nature, we often use simple classifications to help wrap our minds various intricacies. Think about how we classify species interactions: predation, mutualisms, parasitisms, commensalisms, etc. Simple. But complications linger in the background. Former NCSU PhD student Stephanie Archer (along with current student Enie Hensel) demonstrated one such complexity in a recent study (full […]

Antigua to Bahamas hawksbill migration

After finishing nesting on Long Island, Antigua this past summer, this satellite-tagged hawksbill traveled for more than a month to Long Island, Bahamas. The Long Island-to-Long Island migration covered some 1,600 km, one of the longest migrations we have documented at the early stages of our satellite tracking efforts. A cool way to connect study areas among Layman Lab members! […]

Hear the roar of the lionfish recorded for the first time

Here is a popular press piece (link here) on the first documented sound production in lionfish. The original paper well qualifies that these data are just preliminary, but very interesting what role this sound production may play. Here is a paragraph from the article with some speculation:

Sound is a critical component of fish social behaviour and sound production […]

Artificial reefs in Haiti – ampil poisson!

We have been reporting on our long-term artificial reef research in Haiti for a few years now. This year we were pleased to learn that not only did our reefs survive the massive hurricane Mathew, but they also had substantially more fish on them than they did last year. This is a really positive sign that the reefs are providing […]

Fish pee on coral reefs in the Caribbean makes Canadian Broadcasting Company

An interview I did a few months ago for Quarks and Quirks on CBC radio recently aired.  Yes, of course, it is more about fish pee, but I thought I would post it all the same.  It is pretty funny. Scroll down a bit for the actual interview.

Recent work on Nassau Grouper spawning aggregations asks us to rethink current fishing regulations

An exciting new publication just came out helping us better understand Nassau grouper populations in The Bahamas (article here). Using acoustic telemetry data, Dr. Craig Dahlgren and others recorded the movements of different sized Nassau grouper to examine when and where individuals would migrate to spawning aggregations. They found that individuals did not migrate to aggregation sites until they […]
