Condition Of Larval Spanish Mackerel Scomberomorus Maculatus In Relation To The Deepwater Horizon Oil Spill, John Timothy Ransom, J.E. Filbrun, Frank J. Hernandez Jr.
Condition Of Larval Spanish Mackerel Scomberomorus Maculatus In Relation To The Deepwater Horizon Oil Spill, John Timothy Ransom, J.E. Filbrun, Frank J. Hernandez Jr.
Faculty Publications
The Deepwater Horizon oil spill (DWHOS) coincided with the pelagic larval stages of many valued commercial and recreational fishes in the northern Gulf of Mexico. Larval fish survival and eventual recruitment into adult populations may have been impacted directly through toxicity or indirectly through changes in the planktonic food web caused by the release of oil and chemical dispersants during the DWHOS event. Using samples from a long-term ichthyoplankton survey off the coast of Alabama, USA, in a region impacted by the DWHOS, the abundance and condition of larval Spanish mackerel Scomberomorus maculatus were compared during summer months in years …
Condition Of Larval Red Snapper (Lutjanus Campechanus) Relative To Environmental Variability And The Deepwater Horizon Oil Spill, Frank J. Hernandez Jr., J.E. Filbrun, J. Fang, John Timothy Ransom
Condition Of Larval Red Snapper (Lutjanus Campechanus) Relative To Environmental Variability And The Deepwater Horizon Oil Spill, Frank J. Hernandez Jr., J.E. Filbrun, J. Fang, John Timothy Ransom
Faculty Publications
The Deepwater Horizon oil spill(DWHOS)spatially and temporally overlapped with the spawning of many fish species, including Red Snapper, one of the most economically important reef fish in the Gulf of Mexico. To investigate potential impacts of the DWHOS on larval Red Snapper, data from a long-term ichthyoplankton survey off the coast of Alabama were used to examine: (1)larval abundances among pre-impact (2007–2009), impact(2010), and post-impact (2011, 2013) periods; (2) proxies for larval condition (size-adjusted morphometric relationships and dry weight) among the same periods; and (3) the effects of background environmental variation on larval condition. We found that larval Red Snapper …
Land Cover Data For The Mississippi-Alabama Barrier Islands, 2010-2011 Arcgis V10.3 Geodatabase, Gregory A. Carter, Carlton P. Anderson, Kelly L. Lucas, Nathan L. Hopper
Land Cover Data For The Mississippi-Alabama Barrier Islands, 2010-2011 Arcgis V10.3 Geodatabase, Gregory A. Carter, Carlton P. Anderson, Kelly L. Lucas, Nathan L. Hopper
Land Cover Data for the Mississippi-Alabama Barrier Islands, 2010-2011
Land cover on the Mississippi-Alabama barrier islands was surveyed in 2010-2011 as part of continuing research on island geomorphic and vegetation dynamics following the 2005 impact of Hurricane Katrina. Results of the survey include sub-meter GPS location, a listing of dominant vegetation species and field photographs recorded at 375 sampling locations distributed among Cat, West Ship, East Ship, Horn, Sand, Petit Bois and West Dauphin Islands. The survey was conducted in a period of intensive remote sensing data acquisition over the northern Gulf of Mexico by federal, state and commercial organizations in response to the 2010 Macondo Well (Deepwater Horizon) …

For individuals living in environmentally heterogeneous environments, a key component for adaptation and persistence is the extent of phenotypic differentiation in response to local environmental conditions. In order to determine the extent of environmentally induced morphological variation in a natural population distributed along environmental gradients, it is necessary to account for potential genetic differences contributing to morphological differentiation. In this study, we set out to quantify geographic morphological variation in the moon jellyfish Aurelia exposed at the extremes of a latitudinal environmental gradient in the Gulf of Mexico (GoM). We used morphological data based on 28 characters, and genetic data …
Age, Growth, Reproduction, And Diet Of The Finetooth Shark, Carcharhinus Isodon, In The Northern Gulf Of Mexico, Jeremy Michael Higgs
Age, Growth, Reproduction, And Diet Of The Finetooth Shark, Carcharhinus Isodon, In The Northern Gulf Of Mexico, Jeremy Michael Higgs
Master's Theses
The current study examined life history parameters of the finetooth shark, Carcharhinus isodon, in the northern Gulf of Mexico (nGOM) to provide an accurate description of the species’ reproductive biology, age, growth and diet composition. A total of 1,489 finetooth sharks (830 female; 659 male) were collected from coastal waters of the nGOM between Apalachicola Bay, Florida (29.873° N and 84.514° W) and East Bay, Louisiana (28.959° N and 89.279° W) from June 2006 through October 2013. Peak reproductive development occurred during May/June for both males and females, which was followed by mating and an 11-12 month gestation period. …
Fishery And Population Dynamics Of Mississippi’S Spotted Seatrout, David Arthur Dippold
Fishery And Population Dynamics Of Mississippi’S Spotted Seatrout, David Arthur Dippold
Master's Theses
Spotted Seatrout (Cynoscion nebulosus) is the most popular recreational inshore fishery in Mississippi coastal waters. Because of the popularity of Spotted Seatrout in Mississippi as a recreational target and the magnitude of harvest, quantitative approaches to describe the population and fishery dynamics of the Mississippi stock are needed to continue the sustainability of the stock. Quantitative approaches to describing stock dynamics are useful because they can help describe population characteristics, assess the current status of the stock, and be used to evaluate alternative management strategies. In this thesis, I use a suite of quantitative methods to describe, evaluate, …
