The Lionfish Microbiome

A guest post from Julia Stevens, who we are collaborating with on a new lionfish project….

Lionfish have a close relationship with the bacteria living on their skin. Some of these bacteria, seemingly acquired from the environment, are part of a core microbiome that contains similar taxa in both the invaded and native ranges of the lionfish. Overall, the […]

Not Your Average Fish Dissection

Commonplace in many biology courses, laboratory dissections allow students to investigate external and internal anatomy. Unfortunately, many dissection kits contain preserved specimens with faded coloration. At Forfar Field Station on North Andros Island, we have replaced traditional fish specimens with invasive lionfish. Local lionfish removed from Stafford Creek and Fresh Creek provide students with realistically colored models. Students are […]

What else did Columbus bring to The Bahamas?

Another fascinating study out of Rob Dunn’s lab at NCSU. In short, it is an attempt to identify what exotic species may have traveled to the Western World on Columbus’ and other conquistadors’ ships. In Robb’s words: “What we do know is that the ships were likely to have been teeming with thousands of other species, that were incidentally transferred […]

Rats!

Over the last few weeks I’ve been noticing extensive damage to shrubs and small trees. The bark has been removed over long sections of living and (now) dead plants. I wondered what could be doing this.

I had a few ideas. The first possible culprit was pigs. I’ve been seeing a lot of pig sign out in the woods, and marshes. […]

Corn snakes on Great Guana Cay, Abaco?

I was forwarded this photo posted to Facebook that shows a corn snake, Pantherophis guttata, purportedly captured on Great Guana Cay, on or near Baker’s Bay Resort. Corn snakes are native to the Southern US, not The Bahamas.

I haven’t validated the observation so cannot verify its authenticity. However, these snakes appear to travel well in landscaping plants and building […]

What if we are wrong about the lionfish invasion?

The bi-annual Abaco Science Alliance Conference is here. We want to get all posters and talks featured on Abaco Scientist (the first poster is up so far).  One talk on Friday will hopefully generate discussion about conservation priorities, specifically, where do lionfish rank among our most important conservation goals? Here is a draft of the presentation. It […]

Brown anoles invade Bermuda

The most common lizard in The Bahamas, the brown anole (Anolis sagrei), has recently invaded and established itself on Bermuda.

With collaborator James Stroud of Florida International University and with support from the Bermuda Dept. of Conservation and Bermuda Zoological Society, I am examining how this aggressive invader might interact with Bermuda’s only native lizard, the critically endangered Bermuda […]

Controversies and consensus on the lionfish invasion in the Western Atlantic Ocean

A very interesting perspective on the lionfish invasion in this new paper (it is long, but an easy read). The author takes a social science perspective, assessing how the media, resource managers and other stakeholders view the invasion. My favorite parts are some of the extremist quotes she mentions, for example: “It’s like an oil spill that keeps reproducing and will keep […]

Hatchling season is in full swing

An update from Antigua and new NCSU graduate student Andrew Maurer.  Thanks Andrew!

Hatchling season is upon us on Long Island, Antigua. Nests that we saw deposited 50-60 days ago are hatching, often multiple in a night. It usually happens so fast we only see the tracks they leave behind. Seeing tiny hawksbill hatchlings leaves no doubt about it, this is […]
