Microdebris Abundance, Distribution, And Ingestion By Sargassum-Associated Juvenile Fishes In The Gulf Of Mexico, Olivia L. Lestrade, Frank Hernandez
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 …

Monitoring programs can help understand coral disease dynamics. Here, we present results from a national program in the Dominican Republic (DR) aimed at evaluating coral diseases 3 times a year following a nested spatial design. Prevalence of coral diseases in DR varied from sites to regions, suggesting that disease dynamics can be driven by local processes and/or across larger spatial scales. Three diseases were common: Dark Spot (DSD), Yellow Band (YBD) and Stony Coral Tissue Loss Disease (SCTLD). DSD and YBD were more prevalent across the western coast (north and south), whereas SCTLD was restricted for the study period to …

Diatoms Of The Northeastern Gulf Of Mexico: Light And Electron Microscope Observations Of Sulcatonitzschia, A New Genus Of Nitzschioid Diatoms (Bacillariales: Bacillariaceae) With A Transverse Sulcus, James A. Nienow, Akshinthala K. S. K. Prasad
Diatoms Of The Northeastern Gulf Of Mexico: Light And Electron Microscope Observations Of Sulcatonitzschia, A New Genus Of Nitzschioid Diatoms (Bacillariales: Bacillariaceae) With A Transverse Sulcus, James A. Nienow, Akshinthala K. S. K. Prasad
Gulf and Caribbean Research
During a systematic investigation of phytoplankton assemblages in the northeastern Gulf of Mexico (GOM) in the aftermath of the Deepwater Horizon blowout we encountered a population of diatoms morphologically similar to Nitzschia ossiformis (Taylor) Simonsen located about 75 km offshore and concentrated at a depth of 60—120 meters. The density of individuals in the population was sufficient to make detailed observations using light and electron microscopy. Our specimens were frequently united into short ribbon—like colonies. This, plus features of the fine structure of valve (biseriate striae, raphe canal without pores and flush with the valve surface) suggest the GOM population …
Feeding Habits Of The Non-Native Mayan Cichlid, Mayaheros Urophthalmus, In Estuarine Tributaries Of Southwest Florida, Copley H. Smoak, Jeffrey R. Schmid
Feeding Habits Of The Non-Native Mayan Cichlid, Mayaheros Urophthalmus, In Estuarine Tributaries Of Southwest Florida, Copley H. Smoak, Jeffrey R. Schmid
Gulf and Caribbean Research
Foraging habits of the non—native Mayan Cichlid (Mayaheros urophthalmus) were investigated in the tidal tributaries to the Estero Bay and Wiggins Pass estuaries in southwest Florida (USA) during 2011—2013. Dietary analysis was conducted by identifying contents in the digestive tracts of 747 fish and volumetrically measuring the food items. Detritus was the predominant food item by frequency (97–100%), volume (34–48%), and alimentary importance index (47–64%). Bivalves, gastropods, decapod and cirriped crustaceans, coleopterans, serpulid polychaetes, and fish scales frequently (>50%) occurred in samples but volume and importance differed among tributaries. Results indicate that the Mayan Cichlid in southwest Florida tidal …
Gulf Coast Marine Laboratories Past, Present And Future, Donald F. Boesch
Gulf Coast Marine Laboratories Past, Present And Future, Donald F. Boesch
Gulf and Caribbean Research
I spent my nearly 50—year career in marine science working at marine laboratories, most of that as a chief executive officer. So, it is appropriate that my reflections are about marine laboratories, rather than my own science. After relating my career course, I turn my attention to the history and development of marine laboratories along the U.S. coast of the Gulf of Mexico (GOM). Surprisingly, the region’s first laboratory was actually constructed in 1903 at Cameron, LA, but operated less than a decade before closing. It was not until after World War II that the university—affiliated marine laboratories of today …
Diel Activity Patterns And Movement Of Invasive Lionfish (Pterois Volitans/P. Miles) In The Florida Keys Identified Using Acoustic Telemetry, Michael Mccallister, Jeffrey Renchen, Benjamin Binder, Alejandro Acosta
Diel Activity Patterns And Movement Of Invasive Lionfish (Pterois Volitans/P. Miles) In The Florida Keys Identified Using Acoustic Telemetry, Michael Mccallister, Jeffrey Renchen, Benjamin Binder, Alejandro Acosta
Gulf and Caribbean Research
The invasion of Indo—Pacific lionfish (Pterois volitans/P. miles) throughout the Caribbean and southeastern U.S. Atlantic represents a significant ecological threat, yet few studies have examined the daily activity and movement patterns of this invasive species. In this study, passive acoustic telemetry was used to track lionfish at 4 coral reef sites in the Florida Keys. Fourteen lionfish were tagged among the 4 sites, and the total number of days tagged fish were detected ranged from 5 to 141 days. Hourly detection data revealed diel activity patterns with peaks at dawn and dusk. Mixed model analysis of detection data indicated a …

Distribution And Habitat Use Of The Golden Crab Chaceon Fenneri Off Eastern Florida Based On In Situ Submersible And Rov Observations And Potential For Impacts To Deep Water Coral/Sponge Habitat, John K. Reed, Stephanie Farrington, Charles Messing, Andrew David
Gulf and Caribbean Research
This study documents the distribution and habitat preferences of the golden crab, a commercially fished species, in relation to deep-sea coral/sponge ecosystems (DSCEs) at 200-900 m depths off eastern Florida. A total of 386 h of videotapes from 94 submersible and remotely operated vehicle (ROV) dives from 1999 to 2009, covering a total distance of 376 km, were reviewed and characterized for habitat type and presence of crabs. The DSCEs surveyed included Lophelia coral mounds, Miami Terrace, Pourtalès Terrace, and Tortugas Valleys. Video transect data also included environmental surveys of proposed deep-water routes for Liquid Natural Gas (LNG) pipelines, LNG …
The Confluence Of Philosophy And Biology: An Excavation Of Philosophical Issues In Molecular And Developmental Biology, Patrick Johnson Mendie, Emmanuel Bassey Eyo (Ph.D)
The Confluence Of Philosophy And Biology: An Excavation Of Philosophical Issues In Molecular And Developmental Biology, Patrick Johnson Mendie, Emmanuel Bassey Eyo (Ph.D)
Journal of Health Ethics
Philosophical evaluations have played an influential role in the growth and development of molecular and developmental biology to ensure that every individual is born healthy, born wanted and has the privilege to fulfil his or her potentials for a life free from disease and disability. This is why it becomes necessary for biologists to carefully understand human genes, evolution, cells and general human anatomy to fulfil this project. During this process, they are faced with challenges where they also lack the foundation on how to solve them. This challenge gave birth to a philosophical excavation of molecular and developmental biology. …
Effect Of Holothurin On Sarcoma 180 And B-16 Melanoma Tumors In Mice, S.D. Cairns, C.A. Olmstead
Effect Of Holothurin On Sarcoma 180 And B-16 Melanoma Tumors In Mice, S.D. Cairns, C.A. Olmstead
Gulf and Caribbean Research
Holothurin, a biotoxic principle from the Cuvierian glands of the Bahamian sea-cucumber, Actinopyga agassizi, was studied as an anti-tumor agent capable of retarding tumor growth and prolonging the life of tumor-bearing mice. White Swiss mice injected with Sarcoma 180 had a mean survival time of 18.1 days with an average weight gain representing tumor and ascites fluid accumulation amounting to 25.1 grams in 15 days. Of five white Swiss mice with Sarcoma 180 receiving 0.15 mg Holothurin every other day, one was alive at 57 days and the average weight gain of the group was 10.4 grams in 15 …
