A postdoc position is available in Dr. Lou Botsford’s lab at UC Davis, in collaboration with Alan Hastings (UC Davis) and Will White (Oregon State) This position will focus on the dynamics of fished populations inside marine protected areas, and interactions with fishery management. This 2-year position is funded by the California Ocean Protection Council. We seek candidates with strong quantitative skills in population ecology, fisheries, or spatial ecology. See details at link below. Applications should contact Lou Botsford at firstname.lastname@example.org. Full Position Announcement
We are currently recruiting a postdoc to work on population dynamics models for a project at the Guana Tolomato Matanzas NERR, funded by NERR Science Collaborative. This is a 12-month position with the potential for renewal. Ad & application information is here, please contact Dr. White with any questions!
Sophie Perron, NSF REU student in the White lab, presented her summer research today. She used spatial age-structured population models to compare the efficacy of different metrics of larval connectivity information for marine protected area design.
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.

Excited to announce that Victoria Quennessen will join the lab as a MS student in Fall 2018! You should probably follow her on Twitter.
A new paper – in collaboration with David Kimbro (Northeastern) and Chris Stallings (USF) and led by former USF postdoc Tim Pusack (Williams/Mystic) – shows that the southern oyster drill, an important predator on Gulf of Mexico oyster reefs, has lower per capita predation rates in larger groups. This means that oyster mortality during drill outbreaks may be slightly lower than otherwise expected.

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.
