A new paper – led by Northeastern MS student Harriet Booth and in collaboration with David Kimbro (Northeastern), Chris Stallings (USF), and Tim Pusack (Williams/Mystic) – uses a combination of field observations and field experiments to show that a recent increase in the abundance of an oyster predator (crown conch) has unexpectedly not led to the collapse of oyster populations in a Florida estuary, evidently because predation rates decrease at high predator densities.

A new paper – led by Harbor Branch/FAU postdoc Lysel Garavelli and in collaboration with Iliana Chollet (Smithsonian) and Laurent Chérubin (FAU) – applies population dynamics theory to larval connectivity simulations from computational ocean circulation models to find that some northern Caribbean spiny lobster populations may be self-persistent, despite widespread larval disperal.

A new paper – led by UNCW PhD student Verena Wang and in collaboration with Fred Scharf (UNCW) and Steve Arnott (SCDNR) – uses otolith chemistry analysis to show that southern flounder do not return to their natal estuary after spawning migrations. This is additional evidence that the stock is well mixed across the US South Atlantic, and should not be managed as single-state unit stocks.

Will’s research on the relationship between salinity and oyster population dynamics  in Apalachicola Bay, Florida (including Kimbro et al. and Pusack et al.) was brought up during oral arguments in the matter of Florida vs. Georgia before the U.S. Supreme Court. Long story short, more water from Georgia would have mitigated the 2012 oyster fishery collapse, and Florida did not overharvest oysters prior to 2012.
