World squid and octopus populations on a rise

Finally some good news.  With all the drastic changes that are occurring in the worlds oceans, there are clear winners and losers.  A recent article has provided definitive proof that all cephalopods, a group that includes octopus, squid, and cuttlefish, are clear winners. Researchers concluded that cephalopods from New England to Japan have boomed since the 1950s.  What is interesting […]

Sigatoka on Banana

Black and Yellow Sigatoka are two of the most common fungal diseases that infect bananas and plantains. Both diseases have the potential to cause major yield losses if left unchecked. These diseases cause lesions on leaves that greatly reduce the photosynthetic capacity of leaves, thus reducing the availability of food for the plant itself. These diseases are widespread and present in […]

Our Plastic Problem is making the news

As a graduate student I have email alerts for various marine science subjects to try and keep up to date with the latest articles, news posts, blogs, etc. Well, this past week I had an influx of alerts regarding the tremendous amount of plastic that is going into our oceans and wanted to share. Here an article predicts that by 2050 the ratio to plastic mass: fish mass will exceed 1; currently the ratio is 1:5. More so, another article [here] summarizes Jan Zalasiewicz et al. 2016 findings in how humans have created a ‘plastic planet’. […]

Spawning Aggregations

Here is a short video from Natural Numbers that beautifully illustrates how commercial fishing on spawning aggregations, like the Nassau grouper, can often lead to a diminished fishery. Enjoy!

History of Food Web Ecology Paper Out

Working with a group of NCSU graduate students, we put together a brief history of “food web ecology”, i.e., model networks of consumer-resource interactions among a group of organisms, populations, or aggregate trophic units. We framed the study through contributions of 14 accomplished food web ecologists.  The journal posted a pre-print of the paper on-line (still needs a few final […]

Are Lionfish Numbers Up or Down?

In talking with others over recent months, and based on my own observations, lionfish population size seemed to be dropping around Abaco.  But much evidence to the contrary this trip.  There was at least 1 lionfish, and as many as 6, on the small reefs we built back in 2009.  And yesterday I checked some of the sites we used […]

Invasive Lionfish in the Marketplace: Challenges and Opportunities

NCSU graduate student headed up this summary document from the  66th annual meeting of the Gulf and Caribbean Fisheries Institute.  Lots of information, from ciguatera to the economics of the fishery.

Illegal Poaching

If one created a qualitative ratio of “severity of problem” to “general public awareness”, I speculate illegal fishing would be far ahead of any other issue in The Bahamas. A post here on this issue here.

Reef Construction in Haiti Needs No Narrative

Pictures tell the story of an amazing field day.  A tad different from the barge deployment of reefs on Abaco.  Sorry the the video is sideways, but worth flipping your laptop around.

Shrinking conch: size-selective harvest and rapid evolutionary change



Figure 1. Growth of Strombus pugilis, and measures of size and maturity used in this study. (g) is an example of a large mature animal from contemporary populations, while (h) is one of the larger animals from Prehuman populations, exemplifying the shift in size due to human harvest.

A recent paper in Proceedings of the Royal Society B (O’Dea et al. 2014) documents a decrease in the mean size of maturity of West Indian Fighting Conch off the coast of Panama. The study compared fossilized material from time periods prior to (7000 YBP) and following early human occupation of the area as well as materials from contemporary populations. […]
