Bacterial Communities On The Northern Gulf Of Mexico Continental Shelf Are Influenced By Sediment Characteristics Affected By The Mississippi River, Priya Bhattacharya, Stephen C. Landers, Joong-Wook Park
Gulf of Mexico Science
Benthic bacteria in the Gulf of Mexico serve the base of the sediment food chain as a food source for various marine organisms. In this paper, we analyzed the bacterial community and sediment characteristics from 14 sediment samples collected along the continental shelf of the northern Gulf of Mexico. Using the bacterial community to assess relationships among our sites, the data revealed groupings of sites that correlated to the sediment characteristics, generally grouped as western sites in Louisiana near the outflow of the Mississippi River and eastern Florida sites more distant from the outflow. Cluster analysis and multidimensional scaling demonstrated …

Patterns Of Maturity, Seasonal Migration, And Spawning Of Atlantic Croaker In The Western Gulf Of Mexico, Joel Anderson, Dusty Mcdonald, Britt Bumguardner, Zachary Olsen, Jason W. Ferguson
Gulf of Mexico Science
Atlantic croaker (Micropogonias undulatus) are one of the more common finfishes in the Gulf of Mexico. They are a significant component of Gulf bait fisheries and an important midtrophic component of nearshore food webs. In this study, life-history parameters associated with growth, maturity, and seasonal migration were estimated for Atlantic croaker in Texas and integrated into previously described data throughout the rest of the species range. The major findings of this work were the following: (1) a majority (>76%) of age-1 female Atlantic croaker were sexually mature; (2) egress of adults from inshore habitats took place in …

Assessing The Efficacy Of Marsh Restoration Via Terracing By Comparing Vegetation Density And Nekton Abundance Before And After Restoration, Jacob B. Loveless, Delbert Lee Smee
Gulf of Mexico Science
Nueces Bay, a Texas estuary, has been heavily affected by human activities including habitat destruction, pollution, and restriction of freshwater input, leading to a loss of nearly all structured habitats in the bay. To create additional habitat and recover some lost ecosystem services, 160 acres of salt-marsh habitat were created in Nueces Bay in 2010 using marsh terracing. Mounds of marine sediment, or terraces, suitable for growth of Spartina alterniflora, an important foundation species in marshes, were constructed. Several volunteer events involving planting of S. alterniflora occurred in 2011, 2012, and 2013, allowing S. alterniflora to become established. The …

Habitat Selection Among Fishes And Shrimp In The Pelagic Sargassum Community: The Role Of Habitat Architecture, Chelsea O. Bennice, W. Randy Brooks
Gulf of Mexico Science
The pelagic Sargassum community represents an excellent model system to advance our understanding of how a complex habitat can influence biotic interactions. This study examined the habitat architecture of pelagic Sargassum fluitans to determine its effects on habitat selection for one shrimp species (Leander tenuicornis) and two fish species (Stephanolepis hispidus and Histrio histrio). Specifically, we manipulated interthallus spacing and depth of Sargassum habitats independently (i.e., in separate experimental trials) to test whether spatial components of habitat architecture influence habitat selection by these animal inhabitants. Additionally, two differing habitats (Sargassum vs intermingled seagrass species, Thalassia …

Validation Of Image-Based Species Identifications Of Black Corals (Order Antipatharia) On Mesophotic Rocks, Marissa F. Nuttall, Dennis M. Opresko, Emma L. Hickerson
Gulf of Mexico Science
Biodiversity, an important measure of ecosystem health, is challenging to ascertain using sampled specimens in remote deep-sea environments. As image-based identifications become a predominant method for deep-sea species characterizations, there is a need to evaluate the accuracy of species- and genus-level identifications from video and still images to provide a reliable measure of biodiversity. This study presents a validation of the ability to make accurate image-based identifications of black coral species in the northwestern Gulf of Mexico from standard-definition video collected by a remotely operated vehicle. Results indicate that the greatest number of misidentifications occurred at species-level groupings (42.2% error), …

Leaf Growth Rates (Thalassia Testudinum, Banks Ex Koning) As An Indi, Eric C. Milbrandt, Jeff Siwicke
Gulf of Mexico Science
In southwest Florida, changes in hydrology have fundamentally changed the timing and amount of freshwater delivered to the estuarine ecosystem. Biological indicators such as oyster and submerged aquatic vegetation distribution and abundance have been used to establish minimum and maximum discharges to the estuary. These indicators are robust long-term indicators for comparing interannual and climatological changes; however, they lack sensitivity to variable freshwater flows that occur over the course of months or seasons. Seagrass leaf growth rates could provide an integrated biological response for evaluating events caused by climatological shifts (e.g., El Niño) or to evaluate the biological responses to …

Gulf of Mexico Science
Seagrasses provide ecosystem services such as nursery habitats, refuge, and biogeochemical cycling. However, because seagrass communities are in decline, restoration efforts have increased. The seagrass restoration and monitoring programs at the Florida Department of Environmental Protection (FDEP) transplanted plugs of salvaged seagrasses from dock and marine construction sites. In this study, we used a 2-yr-old FDEP transplant site at Big Lagoon, Pensacola, FL, to compare primary production, respiration, and nutrient fluxes in mixed seagrass beds of Thalassia testudinum (turtle grass) and Halodule beaudettei (shoal grass) with intact, native beds of these seagrasses. We placed light and dark incubation chambers in …

Gulf of Mexico Science
Information on the biodiversity and geographic patterns of mesophotic, sessile, epibenthic communities on banks around and at the edge of the continental shelf, northern Gulf of Mexico, has been limited. These communities vary in their environments and are prone to disturbance from Outer Continental Shelf oil- and gas-related activities and fishing (trawling and long-lining). We surveyed these communities on the flanks of 13 banks to determine species richness, species composition, similarities between benthic communities, and geographic patterns in community structure. We sampled to ≤ 181 m in depth via a remotely operated vehicle using a vertically mounted digital camera bearing …
A Historical Perspective Of The Biology And Conservation Of The Kemp's Ridley Sea Turtle, Thane Wibbels, Elizabeth Bevan
A Historical Perspective Of The Biology And Conservation Of The Kemp's Ridley Sea Turtle, Thane Wibbels, Elizabeth Bevan
Gulf of Mexico Science
The history of the critically endangered Kemp’s ridley sea turtle (Lepidochelys kempii) has presented scientists and conservationists with a variety of questions and challenges originating in part from the species’ limited distribution and single primary nesting beach. Although the species was initially brought to the attention of the scientific community in 1880 by Richard Kemp, more than 80 yr passed before Henry Hildebrand revealed the location of its primary nesting beach at Rancho Nuevo, Mexico in the western Gulf of Mexico. By the time scientists began estimating the number of females nesting at Rancho Nuevo, it appeared that …

Gulf of Mexico Science
Kemp’s ridley (Lepidochelys kempii) is the world’s most endangered sea turtle species, and nests primarily on the Gulf of Mexico coast in Mexico. In 1978, a binational project was initiated to form a secondary nesting colony of this species in south Texas at Padre Island National Seashore (PAIS), as a safeguard against extinction. During 1978–2014, we documented 1,667 Kemp’s ridley nests in Texas, with 56% found at PAIS. Most nests (89%) found in south Texas were from wild-stock turtles; south Texas is the northern extent of the documented historic nesting range for the species. We documented nesting in …

We developed a Kemp’s ridley (Lepidochelys kempii) stock assessment model to evaluate the relative contributions of conservation efforts and other factors toward this critically endangered species’ recovery. The Kemp’s ridley demographic model developed by the Turtle Expert Working Group (TEWG) in 1998 and 2000 and updated for the binational recovery plan in 2011 was modified for use as our base model. The TEWG model uses indices of the annual reproductive population (number of nests) and hatchling recruitment to predict future annual numbers of nests on the basis of a series of assumptions regarding age and maturity, remigration interval, …
