Vegetation Species And Bed Position May Drive Epifaunal But Not Nekton Habitat Use In Estuarine Submerged Vegetation In The Mobile-Tensaw River Delta, Alabama, Steven Vroljik, Kathryn O'Shaughnessy, Ashley Mcdonald, Zoey Hendrickson, Bethany Kiley, Anna Reimer, Sierra Robertson, Samantha Smith, Edward Sullivan, Charles Martin
Gulf and Caribbean Research
Submerged aquatic vegetation (SAV) supports nekton and epifaunal macroinvertebrates, sustaining food webs and ecosystem services in estuaries. Invasive SAV can alter these dynamics by displacing native vegetation and restructuring communities. In Alabama’s Mobile-Tensaw Delta (MTD), Eurasian milfoil (Myriophyllum spicatum) is rapidly expanding and outcompeting native wild celery (Vallisneria americana). This study compared nekton and epifaunal assemblages between M. spicatum and V. americana, focusing on edge versus interior positions. Nekton surveys identified 22 taxa (M. spicatum, n = 13; V. americana, n = 18), but assemblages did not differ significantly between vegetation types …
The Critical Role Of Near-Surface Dynamics In Identifying Spawning Areas Of Atlantic Bluefin Tuna In The Gulf Of Mexico, Donald R. Johnson, William J. Teague, Harriet Perry, James S. Franks
The Critical Role Of Near-Surface Dynamics In Identifying Spawning Areas Of Atlantic Bluefin Tuna In The Gulf Of Mexico, Donald R. Johnson, William J. Teague, Harriet Perry, James S. Franks
Gulf and Caribbean Research
Atlantic Bluefin Tuna, Thunnus thynnus (ABFT), migrate long distances to broadcast spawn in the Gulf of Mexico (GOM) basin, the Mediterranean Sea and the Slope Sea (NW Atlantic). These areas have commonalities including a highly dynamic upper ocean eddy environment that draws nutrients from shallow thermoclines and adjacent continental shelves and can provide temporal sanctuaries from some larval predators. In the GOM basin, the Loop Current (LC) and its energetic spin—off eddies sweep weak swimming predators such as jellyfish (Pelagia noctiluca) into lines and aggregations, leaving relatively open areas as temporal sanctuaries for ABFT larvae during the vulnerable …
Oyster Drill (Stramonita Haemastoma Complex) Habitat Preferences In A Shallow Coastal Estuary, Coen Mcgarrah, Cynthia Lupton, Eric Sparks, Jennifer L. Debose
Oyster Drill (Stramonita Haemastoma Complex) Habitat Preferences In A Shallow Coastal Estuary, Coen Mcgarrah, Cynthia Lupton, Eric Sparks, Jennifer L. Debose
Gulf and Caribbean Research
Southern oyster drill snails (Stramonita haemastoma complex) are nuisance organisms within the Gulf of Mexico. This is due to their damaging impact on recovering and farmed oyster (Crassostrea virginica) populations, which are one of the drills’ main food sources. Oyster reef recovery and increased aquaculture production are priorities for Mississippi and the wider northern Gulf coast. The Grand Bay National Estuarine Research Reserve (NERR) hosts multiple oyster reef restoration sites within its boundaries, yet no comprehensive survey of oyster drill abundance has been conducted in this area to date. Additionally, knowledge of oyster drill preferences for sediment …

Between 2006 and 2012, seagrass coverage across Sarasota Bay expanded by 1,108 ha, a 28% increase. During the subsequent years of 2012−2020, 830 ha of seagrass were lost, a 16% decline. In response to these findings, resource management efforts focused on determining the likely reason(s) why those 2 periods had such contrasting trends, to come up with strategies to reverse these losses. Based on results from the seagrass data, the 7—y period of 2006−2012 was designated a “reference period” and water quality data were compared against the subsequent 7—y designated “degraded period” of 2013−2019. Annual average chlorophyll-a (chl-a …

Non-Native Seagrass, Halophila Stipulacea, Reaches Northern Caribbean, Elizabeth R. Whitman, Elizabeth W. Stoner, Stephanie K. Archer
Gulf and Caribbean Research
Halophila stipulacea, a seagrass native to the western Indian Ocean, has become an established invader throughout the western Atlantic, where it often outcompetes native seagrass species across diverse environmental conditions. Here, we report its presence in the northern Bahamas, ca. 2300 km northwest of the first Caribbean record in Grenada and 304 km northeast of the recent observation in Florida, USA. This range expansion represents the northernmost Caribbean record to date and highlights the species’ capacity for long-distance dispersal and continued spread within the region. Our observation underscores the need for coordinated monitoring efforts to track the trajectory of …

Evaluating Donor Site Recovery Following Halodule Wrightii Harvest For Restoration In Northwest Florida, Katie M. Konchar, Becca A. Hatchell, Colin P. Shea, Bradley T. Furman, Kent Smith
Gulf and Caribbean Research
Bare‑root harvesting of Halodule wrightii is widely used to supply donor material for seagrass restoration, yet the capacity of donor meadows to recover in near‑temperate systems remains poorly documented. We evaluated donor‑site recovery following bare‑root harvesting in St. Andrew Bay, northwest Florida—an estuary at the northern extent of Tropical Atlantic Bioregion 2 where H. wrightii exhibits strong seasonal senescence and a shortened growing season. Thirty harvest impact sites were monitored for 388 days to quantify changes in shoot density, percent frequency, and sediment elevation relative to nearby reference conditions. Shoot density and percent frequency at harvested sites converged with reference …

The Bahia Grande is a 6,500—acre tidal basin located at the southernmost tip of Texas. Tidal flow into this coastal estuary was cut off in the 1930s, causing the basin to dry up for ~70 y. A pilot channel connecting the Bahia Grande to tidal waters was constructed in 2005, allowing flooding of the basin to occur. Throughout the period reported herein (2005–2019), the system remained characterized by persistent spatial and temporal episodes of extreme hypersalinity (>70)—a critical factor influencing estuarine community composition and driving key ecological processes. With additional rehabilitation actions forthcoming, characterization of the estuary is essential …

Gulf and Caribbean Research
Once vibrant ecosystems, coral reefs are degrading at unprecedented rates due to natural and human—induced disturbances, necessitating immediate restoration and conservation efforts. Evaluating the success of these projects often involves assessing changes in reef biodiversity. Bioacoustics has emerged as a promising, non—invasive method for such evaluations, though its efficacy remains debated. This study aimed to determine whether the diurnal soundscapes of restored coral reefs are consistent across different time frames (months) and spatial scales (reefs), which is crucial for developing reliable monitoring tools for reef health. To achieve this, 2 commonly used acoustic indices, the Acoustic Complexity Index (ACI) and …
The Effects Of A River Closure On A Snook (Centropomus Spp.) Nursery Community In The Rio Grande River, Texas, Ethan Getz, Perry Trial, Catherine Eckert, Joel Anderson
The Effects Of A River Closure On A Snook (Centropomus Spp.) Nursery Community In The Rio Grande River, Texas, Ethan Getz, Perry Trial, Catherine Eckert, Joel Anderson
Gulf and Caribbean Research
Snook (Centropomus spp.) support important fisheries in the Gulf of Mexico and populations are increasing in Texas. However, a primary snook nursery, the Rio Grande River, remains one of the most imperiled rivers in North America. In 2001—2002, low flows led to the formation of a sandbar and the complete blockage of the Rio Grande, eliminating exchange with coastal waters. Here, data collected by the Texas Parks and Wildlife Department were used to determine how the Rio Grande closure affected juvenile and subadult snook and the estuarine community. Seine and trawl samples were collected prior to (1992—1997) and during …

Gulf and Caribbean Research
Previously the algal community of Cuban mesophotic coral reef ecosystems (MCEs) has not been characterized quantitatively. The objective of this study was to explore the distribution of macroalgae around Cuba and their depth profiles within the mesophotic zone (30−150 m). Data on the algal community were obtained in 2017 during 43 ROV (remotely operated vehicle) dives around Cuba’s shelf. Scientists specializing in algal taxonomy watched the live ROV video on board the ship and recorded algal presence every ~5—10 min in a database. Algae were identified to the lowest possible taxa, and algal presence/absence was analyzed in 20 m depth …

Ina Scuba: Mobilization Of French West Indies Scuba Diving Clubs To Rapidly Improve Knowledge On Threatened Marine Species. Case Of The White-Spotted Eagle Ray (Aetobatus Narinari)., Océane Beaufort, Rocio Prieto González
Gulf and Caribbean Research
The White—Spotted Eagle Ray (Aetobatus narinari), listed as Endangered on the IUCN Red List since 2021, is experiencing alarming population declines, underscoring the urgent need for targeted conservation efforts. This species, which plays a vital ecological role in marine food webs, has biological and ecological characteristics that make it particularly vulnerable to habitat degradation and anthropogenic pressures, particularly fishing, tourism, and maritime traffic. In the French West Indies (FWI), the paucity of data on the White—Spotted Eagle Ray remains a major obstacle to the development of effective, island—specific conservation strategies. To address this gap, the INA Scuba participatory …

3d-Printed Polylactide Structures Do Not Affect The Demography Of The Threatened Coral Acropora Cervicornis, Gabriela Baerga-Jiménez, Alex E. Mercado-Molina
Gulf and Caribbean Research
The development of artificial structures using emerging 3D printing technology has been proposed as a possible strategy to promote the recovery of degraded coral reef ecosystems. Current technologies allow 3D printers to faithfully replicate the morphology of coral reef attributes (e.g., substrate and coral colonies). Thus, 3D printing can be used to create artificial structures that replicate microhabitats resembling those found by reef organisms in nature. However, the use of 3D printing technology for reef conservation and restoration purposes is still in its early developmental stages. Consequently, the potential benefits or detriments of the technology on coral reef health and …

Use Of Light Traps To Assess The Taxonomy And Seasonality Of Early Life Stages Of Fishes Recruiting To Upper Matagorda Bay In Texas, Polly Hajovsky, Joel Anderson, Damon Williford
Gulf and Caribbean Research
Detecting the ingress of larval and early juvenile fishes into estuaries is crucial for understanding the early life stages and population dynamics of species—specific recruitment seasonality. However, monitoring these early life stages presents challenges due to their small size, seasonal variability, spatial patchiness, and their use of structurally complex habitats. Although plankton nets have been widely used to sample larval fishes, light traps have been found to have more flexibility, durability, and cost—effective. This study aimed to assess the effectiveness of light traps for sampling larval and early juvenile fishes in a Texas estuary. The objectives of this study were …

Permanent monitoring programs are valuable to identify drivers of ecosystem trends. For example, in 2021, we reported the first record of Stony Coral Tissue Loss Disease (sctld) along the northeastern coast of the Dominican Republic, affecting major reef—building coral species with a prevalence above 30%. However, a few sites such as Carenero remained unaffected by sctld for almost 2 years. The average coral cover in this site was about 18—25% (mean 18.3% ± sd 1.5), and disease prevalence did not exceed 7% in the coral community. During the first quarter of 2022, a few colonies (

An Aggregation Of The Pandalid Shrimp, Heterocarpus Ensifer, On Deep Reef Habitats Of The West Florida Slope, Eastern Gulf Of Mexico, Steve W. Ross
Gulf and Caribbean Research
Heterocarpus ensifer A. Milne—Edwards (1881) (Crustacea: Pandalidae), armed nylon shrimp, is widely distributed in the western and eastern North Atlantic Ocean. In the western Atlantic this shrimp occurs from off North Carolina to Brazil and in the Gulf of Mexico (GOM), western Bahamas, and Caribbean Sea at depths of 170—885 m. Despite its widespread occurrence, ecology or biology information for this species are sparse, and in situ observations of abundance, behavior and habitat preferences are particularly lacking. During extensive submersible and ROV observations on and near deep—reefs in the north—central and eastern GOM, a remarkably large aggregation of H. ensifer …

Benthic colonial hydroids often serve as a host to a large variety of invertebrate taxa. The colonial hydroid Eudendrium carneum Clarke, 1882 is host to a variety of epifauna, including the recently described nudibranch Dondice jupiteriensis García—Méndez & Valdés, 2022. Like many species of heterobranch sea slugs, little is known about the natural history and population biology of D. jupiteriensis. Here we describe a year—long study recording the population density and size structure of D. jupiteriensis on E. carneum colonies in Tampa Bay, FL USA. We found that the D. jupiteriensis population persists year—round but is the densest during …

Estuarine submerged aquatic vegetation (SAV) provides vital habitat for macroinvertebrate communities that support diverse food webs and subsequent ecosystem services. Invasive SAV, however, has the potential to alter estuarine food webs through competition with native SAV, resulting in different associated biological communities. In the Mobile-Tensaw Delta (Alabama, USA), the invasive Eurasian milfoil, Myriophyllum spicatum, is fast becoming the dominant SAV, out-competing native SAV such as wild celery, Vallisneria americana. This study investigated the above- and belowground macroinvertebrate assemblages associated with these SAV habitats. We found significantly different assemblages between the SAV, with V. americana supporting more even and …

Data—limited stock assessment methods have the potential to positively impact livelihoods of fishermen around the world by providing management recommendations that aim to optimize sustainable yields from fisheries. Some years ago, a novel length— based (LB) method was developed for the assessment of spawning potential ratio (SPR), a measure of the reproductive capacity of fish stocks. We applied the LB—SPR method to 5 important target species of the coastal gillnet fishery in Guyana and Suriname. Nebris microps (Smalleye Croaker; 32% SPR) and Macrodon ancylodon (King Weakfish; 34% SPR) had the highest spawning potential, but remained below the 40% target level …

Microdebris Abundance, Distribution, And Ingestion By Sargassum-Associated Juvenile Fishes In The Gulf Of Mexico, Olivia L. Lestrade, Frank Hernandez
Gulf and Caribbean Research
Holopelagic Sargassum is a critical nursery habitat for the early life stages of many marine fishes, including several federally managed species in the United States and Caribbean. Sargassum is often aggregated along surface convergence features where microdebris (synthetic, semi—synthetic, and naturally—derived particles size) have also been found in relatively high concentrations. In this study, we collected microdebris from Sargassum and adjacent open water habitats (in 2018), and juvenile fishes from Sargassum (in 2017 and 2018) in the northern Gulf of Mexico to quantify habitat—specific microdebris concentrations and the degree to which Sargassum—associated juvenile fishes ingest microdebris. Microdebris concentrations within …

Since 2012, the benthic communities of the Pigeon Islets (Guadeloupe Island, Lesser Antilles) have been monitored biannually by the National Park of Guadeloupe using photo—quadrats. This monitoring was carried out at 12 coral reef stations distributed around the islets. The data collected from 2012 to 2021 highlight the significant events that disrupted the coral communities of Guadeloupe. Among these remarkable phenomena, an episode of coral bleaching occurred in 2019, followed by the appearance of a new coral disease, Stony Coral Tissue Loss Disease (SCTLD), in 2020. As a result of these threats, a drop of 54% of coral cover was …
