Can Swimming Depth Data From Multiple Pacific Herring Individuals Be Used To Estimate Characteristics Of Their School? Verification By Micro Bio-Loggers, Makoto Tomiyasu, Yuki Iino, Hokuto Shirakawa, Kazushi Miyashita

Journal of Marine Science and Technology–Taiwan

Bio-logging and bio-telemetry are effective methods for monitoring the activity of aquatic animals. Tagging technology has recently advanced, and it is now possible to use tracking devices on small fish and multiple individuals. For species that live in schools such as small pelagic fish, analyzing the activity of multiple individuals may help to further our understanding of school activity in nature. In this study, we tracked the swimming depth of multiple individuals of schooling Pacific herring and examined whether the school’s characteristics and activity can be estimated from the individuals’ swimming depth in the laboratory and a set net experiment. …

New Records Of Three Deep-Sea Bathymodiolus Mussels (Bivalvia: Mytilida: Mytilidae) From Hydrothermal Vent And Cold Seeps In Taiwan, Meng-Ying Kuo, Dun- Ru Kang, Chih-Hsien Chang, Chia-Hsien Chao, Chau-Chang Wang, Hsin-Hung Chen, Chih-Chieh Su, Hsuan-Wien Chen, Mei-Chin Lai, Saulwood Lin, Li-Lian Liu

Journal of Marine Science and Technology–Taiwan

The deep sea mussel genus, Bathymodiolus Kenk & Wilson, 1985, contains 31 species, worldwide. Of which, one endemic species (Bathymodiolus taiwanesis) was reported from Taiwan (MolluscaBase, 2018). Herein, based on the mitochondrial COI results, we present 3 new records of the Bathymodiolus species from Taiwan, namely Bathymodiolus platifrons, Bathymodiolus securiformis, and Sissano Bathymodiolus sp.1 which were collected from vent or seep environments at depth ranges of 1080-1380 m. Therefore, a total of four species in the genus of Bathymodiolus are now known from Taiwan.

Bioluminescent Flashes Drive Nighttime Schooling Behavior And Synchronized Swimming Dynamics In Flashlight Fish, David F. Gruber, Brennan T. Phillips, Rory O'Brien, Vivek Boominathan, Ashok Veeraraghavan, Ganesh Vasan, Peter O'Brien, Vincent A. Pieribone, John S. Sparks

Publications and Research

Schooling fishes, like flocking birds and swarming insects, display remarkable behavioral coordination. While over 25% of fish species exhibit schooling behavior, nighttime schooling has rarely been observed or reported. This is due to vision being the primary modality for schooling, which is corroborated by the fact that most fish schools disperse at critically low light levels. Here we report on a large aggregation of the bioluminescent flashlight fish Anomalops katoptron that exhibited nighttime schooling behavior during multiple moon phases, including the new moon. Data were recorded with a suite of low-light imaging devices, including a high-speed, high-resolution scientific complementary metal-oxide-semiconductor …

High-resolution satellite images of ocean color and sea surface temperature reveal an abundance of ocean fronts, vortices and filaments at scales below 10 km but measurements of ocean surface dynamics at these scales are rare. There is increasing recognition of the role played by small scale ocean processes in ocean-atmosphere coupling, upper-ocean mixing and ocean vertical transports, with advanced numerical models and in situ observations highlighting fundamental changes in dynamics when scales reach 1 km. Numerous scientific publications highlight the global impact of small oceanic scales on marine ecosystems, operational forecasts and long-term climate projections through strong ageostrophic circulations, large …

Incidence And Prevalence Of Francisella Noatunensis Subsp. Orientalis (Fno) Pathogenic Infections In Feral Hawaiian Tilapia, Daquille Peppers

Biology Theses

Aquaculture has become a major food source for many countries and continues to grow each year. However, many of the fishes that are farmed are susceptible to pathogenic infections such as Francisellosis, a bacterial infection that contributes to disease and high mortality rate in many populations of farmed and wild fish around the world. In 1994, feral and farmed populations of tilapia (e.g. Oreochromis mossambicus) on Oahu, Hawaii were found to be infected with a novel Francisellosis strain, Francisella noatunensis subsp. orientalis (Fno). To prevent the spread of this pathogen, the Hawaii Department of Aquaculture (HDOA) initiated …

Fucus Distichus: Investigating Humidity And Temperature Between Tides, Jason Thomas, Andrew Chang, Julia Blum, Chela Zabin

STAR Program Research Presentations

Environmental elements such as changing rapidly changing temperature, prolonged periods of low to no water exposure, desiccation, predation and increased wave action can influence the diversity of microhabitats that inhabit the littoral zones. When making observations of various shorelines, specifically the physical conditions of the surrounding marine vegetation (i.e. Fucus distichus), an inquiry is made as to the role of Fucus in the amelioration of stressors on the marine habitat during low tide (MLLW), however, due to time considerations, temperature and humidity are the focus of this study. Using temperature and humidity probes, monitoring data shows that Fucus provides …

The Campeche Sound is the major offshore oil producing area in the Southern Gulf of Mexico (SGoM). To evaluate the impact of oil related activities in the ocean floor sediments, we analyzed the geochemical (major and trace element, organic carbon and hydrocarbon concentrations) and biological (benthic foraminifera) composition of 62 superficial sediment samples, from 13 to 1336 m water depth. Cluster and Factor analysis of all the variables indicate that their distribution patterns are mainly controlled by differences between the terrigenous and carbonate platforms in the SGoM. Benthic foraminiferal assemblages were abundant and diverse, and their distribution patterns are mainly …

Characterization Of Red Mangrove Proproot Epibiont Communities Of St. Johns Usvi, Alan M. Buob

Theses, Dissertations and Culminating Projects

In May 1989, Hurricane Hugo impacted St. Johns USVI destroying the Red Mangrove (Rhizophora mangle) Forest of Great Lameshur Bay. The impact restricted the tidal flow and caused massive destruction in the mangroves. Hurricane Marilyn (1995) hit St. John causing the storm wall formed by Hugo to be washed out. It returned limited tidal flow to the dead forest. It was not until a subsequent hurricane in 2010 broke down the sediment wall and natural flow returned. Up to that point, water quality restricted any fouling organisms’ survival on the prop roots. By using photo identification, three different bays of …

Evaluating Responses Of Benthic Macrofauna To Artificial Reef Presence In The Gulf Of Mexico, Douglas Faircloth

Theses and Dissertations

Artificial reef research has long concerned itself with the interactions of fishes and has tended to favor commercially valuable species. Because of this, a larger yet less known group that heavily benefits fishes have been overlooked; benthic macrofauna. Benthic macrofauna are marine invertebrates that live below the sediment-water interface and play many roles in the ecosystem. Macrofauna are important prey items, ecosystem engineers, and bioindicators, as well as being ubiquitous in the marine environment. Since macrofauna have been largely ignored in this field, not much is known regarding their interaction with the placement of artificial reefs. To try and fill …

Developing Multispectral Imaging Techniques To Determine Canopy Coverage And Carbon Storage Of Seagrasses In The Gulf Of Mexico, Ivy Michelle Hinson

Theses and Dissertations

Although seagrass beds provide global ecosystem services, coverage is in rapid decline, with the capacity of seagrasses to sequester carbon of special concern. Current seagrass monitoring methods are labor intensive and may not offer a complete picture of coverage. Remote sensing offers the ability to oversee landscapes but water in coastal environments presents challenges, as the commonly used near-infrared wavelength dissipates in water.

This project aimed to provide reliable methodology to assess seagrass coverage using multispectral imagery taken from an unmanned aerial vehicle and to provide evidence for the link between seagrass coverage and stored belowground carbon for common seagrasses …

Spatial And Temporal Variation In The Diet Composition Of Zooplankton In Mission Bay, Bryanna Paulson

Theses

Analyses of quantitative data on zooplankton diets are vital for understanding the drivers of zooplankton abundance within an ecosystem. Such analyses also provide insight into trophic pathways within the lower planktonic food web, which support populations of higher trophic level species. This study used carbon and nitrogen stable isotope ratios of size-fractionated plankton in Mission Bay, San Diego, CA to examine the spatial and temporal variation in zooplankton trophic ecology and determine potential environmental drivers of zooplankton community structure. Carbon stable isotopes reflect primary production sources in an organism’s diet, and nitrogen stable isotope ratios can be used to estimate …

Reconstruction Of Northeastern Pacific Ocean Holocene Production Using Marine Mammal Archaeofauna, Andrea M. Traffichini

HCNSO Student Theses and Dissertations

Changes in marine production play a key role in determining the trophic structure of the northeastern Pacific Ocean. This is a region of great environmental fluctuations due to modern, historical, and paleo-environmental variability recorded throughout the Holocene. These fluctuations are recorded in the bone collagen of the marine mammals that reside in these waters. Marine mammal remains from four previously excavated archaeological deposits on Unalaska Island, Alaska are used as a proxy for marine production changes throughout the Holocene (4,500 BP to 350 BP). Historic and modern samples from museum collections, subsistence harvests, and previously published data provide a distinct …

A Characterization Of A Southeast Florida Stony Coral Assemblage After A Disease Event, Nicole K. Hayes

HCNSO Student Theses and Dissertations

Coral reefs have declined globally due to anthropogenic stressors increasing the frequency and severity of bleaching and disease events. In 2014, a stony coral tissue loss disease (SCTLD) outbreak occurred off the coast of southeast Florida and subsequently spread throughout the region. Data collected by the Southeast Florida Reef Evaluation and Monitoring Project (SECREMP) were used to examine the regional impacts of the disease event on the Southeast Florida stony coral assemblage. A long-term annual monitoring project, SECREMP samples permanent sites along the Southeast Florida Reef Tract (SEFRT) from Miami-Dade County north to Martin County. Analysis of stony coral demographic …

Spatial And Temporal Trends In The Xestospongia Muta (Giant Barrel Sponge) Population On The Southeast Florida Reef Tract, Alanna D. Waldman

HCNSO Student Theses and Dissertations

Xestospongia muta, the giant barrel sponge, is a key component of coral reef benthic communities in Southeast Florida and the Caribbean. Xestospongia muta increases habitat complexity and stability, and filters large volumes of water, enhancing water quality and facilitating nutrient cycling. Therefore, it is important to investigate trends in the X. muta population on Southeast Florida reefs in response to anthropogenic stressors, changing environmental conditions and acute disturbances and how these events affect its ecological role in the benthic community. This study identified trends in X. muta population density, volume, and size class distribution over time and across reef …

SLRad data generated include sample activity as disintegrations per minute per gram(dpm/g) of 1) Excess Thorium-234 (234Thxs) activity, which is calculated by measuring the total Thorium-234 (234ThTot) activity and the subtraction of the measured or estimated “Supported” Thorium-234 (234ThSup) activity, 2) Excess Lead-210 (210Pbxs) activity, which is calculated by measuring the total …

Timing And Potential Drivers Of Symbiont Selection In The Early Life Stages Of The Massive Starlet Coral Siderastrea Siderea, Sarah G. Koerner

HCNSO Student Theses and Dissertations

The ability of corals to build reefs can be attributed to their relationship with single-celled algae of the familySymbiodiniaceae.Through the process of photosynthesis, these algae can provide their coral hosts with over 90% of their daily energy requirements. Most coral species acquire multiple species of symbionts from the surrounding water during their larval stage or immediately after settling. However, over time, the coral will select a dominant symbiont speciesthat can depend on the local environment. Until this study, the size or age of the coral at which this transition from multiple Symbiodiniaceaespecies to one dominant species occurs has remained …

Shallow- Water Hardbottom Communities Support The Separation Of Biogeographic Provinces On The West- Central Florida Gulf Coast, Shelby Eagan

HCNSO Student Theses and Dissertations

Several studies have found separation of biogeographic provinces on the West Florida Shelf (WFS), but the location of this separation differs depending on different organisms with faunal boundaries proposed at Apalachicola, Cedar Key, Anclote Key. Tampa Bay, Charlotte Harbor, Cape Romano, or Cape Sable. Biogeographic boundaries can be gradual over a given space and are often species-specific. Analyses of marine benthic mapping and community characterization of Florida’s West-central coast shallow water (depth) hardbottom habitats indicate a major shift in the benthos across Tampa Bay. Quantitative benthic surveys of 29 sites yielded a total of 4,079 individuals of nine stony coral …

Desperate Coral Larvae? Behavioral Responses To Settlement Cues In Aging Agaricia Agaricites Larvae, Helena Sasha Fulmore

HCNSO Student Theses and Dissertations

The global stressors of ocean warming and acidification, as well as local stressors such as eutrophication, overfishing, and coastal construction, have all contributed to the severe decline in coral populations worldwide. Recovery of coral reefs depends partly on recruitment, which relies on the response of larvae to settlement cues indicative of habitat quality; however, it remains unclear whether recruitment in disturbed areas will be compromised. Specifically, as reefs become more disturbed and dominated by macroalgae, it is important to understand larval behavior in response to changes in habitat quality. In this study, we first assessed the settlement success of newly …
