High Resolution Study Of The Spatial Distributions Of Abyssal Fishes By Autonomous Underwater Vehicle, Rosanna Milligan, K. J. Morris, B. J. Bett, J. M. Durden, D. O. B. Jones, K. Robert, H. A. Ruhl, D. M. Bailey May 2016

High Resolution Study Of The Spatial Distributions Of Abyssal Fishes By Autonomous Underwater Vehicle, Rosanna Milligan, K. J. Morris, B. J. Bett, J. M. Durden, D. O. B. Jones, K. Robert, H. A. Ruhl, D. M. Bailey

Marine & Environmental Sciences Faculty Articles

On abyssal plains, demersal fish are believed to play an important role in transferring energy across the seafloor and between the pelagic and benthic realms. However, little is known about their spatial distributions, making it difficult to quantify their ecological significance. To address this, we employed an autonomous underwater vehicle to conduct an exceptionally large photographic survey of fish distributions on the Porcupine Abyssal Plain (NE Atlantic, 4850 m water depth) encompassing two spatial scales (1–10 km2) on and adjacent to a small abyssal hill (240 m elevation). The spatial distributions of the total fish fauna and that …

An Alternate Trawling Method: Reduced Bycatch And Benthic Disturbance Achieved With The Wing Trawling System, Geoffrey Udoff May 2016

An Alternate Trawling Method: Reduced Bycatch And Benthic Disturbance Achieved With The Wing Trawling System, Geoffrey Udoff

LSU New Orleans Theses and Dissertations

The Wing Trawling System (WTS) was tested as an alternative to traditional shrimp capture methods in the Gulf. Compared to an otter trawl, this trawl was conceived to reduce bycatch, retain shrimp catch, and minimize seafloor disturbance. Through seventy-one paired tows, the WTS was assessed against a standard otter trawl. The WTS was found to reduce bycatch by 63-65% and reduce shrimp catch by 30-35%. Additionally, I measured the depth of the scars produced by both trawls and quantified the turbidity of the plumes behind them. The scars left by the WTS and the otter trawl were between 9.9 …

Rapid Lateral Extraction Of Otoliths That Maintains The Integrity Of Fish Product To Improve Access To Catches And Reduce Potential Sampling Biases, Corey B. Wakefield, Dion K. Boddington, Stephen J. Davies May 2016

Rapid Lateral Extraction Of Otoliths That Maintains The Integrity Of Fish Product To Improve Access To Catches And Reduce Potential Sampling Biases, Corey B. Wakefield, Dion K. Boddington, Stephen J. Davies

Fisheries Research Articles

The capacity to sample otoliths of fish from commercial, recreational, artisanal or subsistence catches can be constrained if the dissection process results in alterations to their external appearance and thus reduces its value and/or shelf life. There can also be significant biases incorporated into the collection of otolith samples if access is only granted relative to the size of the fish (i.e. if smaller fish are sold whole). To reduce such limitations, we herein describe a rapid and simple method of lateral otolith extraction that maintains the integrity of the fish product, and thus reduces potential biases in sample …

Ocean Acidification And Predator-Prey Relations: Correlating Disruption Of Predator Avoidance With Chemosensory Deficits, Alexandra Fw Sidun, William G. Wright May 2016

Ocean Acidification And Predator-Prey Relations: Correlating Disruption Of Predator Avoidance With Chemosensory Deficits, Alexandra Fw Sidun, William G. Wright

Student Scholar Symposium Abstracts and Posters

One of the most destructive effects of global climate change is the increased carbon sequestering and consequential acidification of our world’s oceans. The impacts of ocean acidification on marine organisms are still relatively unknown, especially effects on behavioral ecology. Avoiding predation has emerged from recent behavioral ecology literature as a critical feature in the life history of a wide array of animal species; experiments on marine fishes suggest acidic water compromises their predator-avoidance abilities. Recent assays in our lab suggest predator-induced behavior is reduced by weakly acidic water. These experiments do not address the potential factor of generalized malaise caused …

Connecting The Physiological And Behavioral Response To Heat Stress On A Warming Planet, Anastasia Kalyta May 2016

Connecting The Physiological And Behavioral Response To Heat Stress On A Warming Planet, Anastasia Kalyta

Student Scholar Symposium Abstracts and Posters

Intertidal communities are considered good models of the biological effects of climate change on ecosystems, as their resident organisms are subjected to heat spells during daytime low tides. The increasing heat exposure can elicit behavioral as well as physiological responses in intertidal organisms. We studied the relationship between these responses to heat stress in the blue-banded hermit crab, Pagurus samuelis, by inducing a “heat shock” with elevated water temperature of 29 °C for 2.5 h. The behavioral effect of heat-shock was quantified using a 30-minute feeding assay, measuring the mass of a standard squid pellet consumed by individual hermit crabs. …

Bioavailability Of Dissolved Organic Matter In The North Inlet Estuary, Andrew Mason Gaines Banks May 2016

Bioavailability Of Dissolved Organic Matter In The North Inlet Estuary, Andrew Mason Gaines Banks

Senior Theses

Dissolved organic matter (DOM) is an important source of carbon and energy for microbial food webs in estuaries. The export of DOM from estuaries to the coastal ocean influences shelf productivity and biogeochemical cycles. Chromophoric dissolved organic matter (CDOM) is an important component of the DOM pool that absorbs light, and is photoreactive. There are various optical properties of CDOM that can be used to indicate the sources of DOM, such as whether or not it is derived from terrestrial or marine environments. In this study, the sources and bioavailability of DOM were characterized in the North Inlet estuary near …

Comparative Use Of A Caribbean Mesophotic Coral Ecosystem And Association With Fish Spawning Aggregations By Three Species Of Shark, Alexandra E. Pickard, Jeremy Vaudo, Bradley M. Wetherbee, Richard S. Nemeth, Jeremiah Blondeau, Elizabeth Kadison, Mahmood S. Shivji

Marine & Environmental Sciences Faculty Articles

Understanding of species interactions within mesophotic coral ecosystems (MCEs; ~ 30–150 m) lags well behind that for shallow coral reefs. MCEs are often sites of fish spawning aggregations (FSAs) for a variety of species, including many groupers. Such reproductive fish aggregations represent temporal concentrations of potential prey that may be drivers of habitat use by predatory species, including sharks. We investigated movements of three species of sharks within a MCE and in relation to FSAs located on the shelf edge south of St. Thomas, United States Virgin Islands. Movements of 17 tiger (Galeocerdo cuvier), seven lemon (Negaprion …

A Comparative Study Of Isolation In Headwater Fishes, Bjorn Victor Schmidt May 2016

A Comparative Study Of Isolation In Headwater Fishes, Bjorn Victor Schmidt

Dissertations

Headwater resident fishes may be prone to a high rate of population fragmentation within river networks because large streams have habitat conditions outside of their preferred ecological niche and may limit gene flow in the dendritic ecological network. To investigate patterns of population structure, asymmetrical gene flow, and influences on genetic distance and isolation from connecting habitat pathways, species specific ecological traits, and basin scale characteristics, a multi-species, multi-regional study was performed. Six headwater species of fish from four taxonomic groupings were sampled for genetic material in three regions of paired neighbor drainages and then genotyped for eight microsatellite loci. …

Examining The Effectiveness Of Coral Restoration Nurseries, Grace Hanson May 2016

Examining The Effectiveness Of Coral Restoration Nurseries, Grace Hanson

Senior Honors Projects

Numerous ecosystems throughout the world are declining and facing conservation challenges. A variety of techniques have been developed in response with active restoration being one of them. Active restoration usually involves planting vegetation in order to restore the area to its previous state. It has been used in multiple ecosystems including seagrasses, forests, and salt marshes. Coral reefs have experienced severe declines worldwide and active restoration has been utilized to help combat their decline. It is generally done by collecting healthy fragments of coral and either transplanting them directly to a declining reef or placing them on a nursery allowing …

Potential And Timescales For Oxygen Depletion In Coastal Upwelling Systems: A Box-Model Analysis, Cheryl S. Harrison, B. Hales, S. Siedlecki, R. M. Samelson May 2016

Potential And Timescales For Oxygen Depletion In Coastal Upwelling Systems: A Box-Model Analysis, Cheryl S. Harrison, B. Hales, S. Siedlecki, R. M. Samelson

School of Earth, Environmental, & Marine Sciences Faculty Publications

A simple box model is used to examine oxygen depletion in an idealized ocean-margin upwelling system. Near-bottom oxygen depletion is controlled by a competition between flushing with oxygenated offshore source waters and respiration of particulate organic matter produced near the surface and retained near the bottom. Upwelling-supplied nutrients are consumed in the surface box, and some surface particles sink to the bottom where they respire, consuming oxygen. Steady states characterize the potential for hypoxic near-bottom oxygen depletion; this potential is greatest for faster sinking rates, and largely independent of production timescales except in that faster production allows faster sinking. Timescales …

Turning Performance In Squid And Cuttlefish: Unique Dual-Mode, Muscular Hydrostatic Systems, Rachel A. Jastrebsky, Ian K. Bartol, Paul S. Krueger

Biological Sciences Faculty Publications

Although steady swimming has received considerable attention in prior studies, unsteady swimming movements represent a larger portion of many aquatic animals' locomotive repertoire and have not been examined extensively. Squids and cuttlefishes are cephalopods with unique muscular hydrostat-driven, dual-mode propulsive systems involving paired fins and a pulsed jet. These animals exhibit a wide range of swimming behavior, but turning performance has not been examined quantitatively. Brief squid, Lolliguncula brevis, and dwarf cuttlefish, Sepia bandensis, were filmed during turns using high-speed cameras. Kinematic features were tracked, including the length-specific radius of the turn (R/L), a measure of maneuverability, and …

Collected Faculty Scholarship

Horseshoe crabs are xiphosuran chelicerates, the sister groupto arachnids. As such, they are important for understandingthemost recent common ancestor of Euchelicerata and the evolution and diversification of Arthropoda. Limulus polyphemus is the most investigated of the four extant species of horseshoe crabs, and the structure and function of its visual system have long been a major focus of studies critical for understanding the evolution of visual systems in arthropods. Likewise, studies of genes encoding Limulus opsins, the protein component of the visual pigments, are critical for understanding opsin evolution and diversification among chelicerates, where knowledge of opsins is limited, and …

Systematic Patterning Of Sediments In French Polynesian Coral Reef Systems, Andrew Calhoun Apr 2016

Systematic Patterning Of Sediments In French Polynesian Coral Reef Systems, Andrew Calhoun

HCNSO Student Theses and Dissertations

Through a discipline termed “comparative sedimentology”, modern carbonate depositional environments have been used extensively as analogs to aid in the interpretation of equivalent fossil systems. Using field samples, GIS and remote sensing data for three isolated carbonate platforms in the Pacific, this thesis seeks to examine relationships between grain texture and grain type and their environment of deposition. The motivation is to highlight relationships that have the potential to better understand facies relations on carbonate platforms, and thereby reduce uncertainty and increase accuracy of subsurface exploration. The results of this study show that on Raivavae, Tubuai, and Bora Bora: French …

Assessment Of Recent Eastern Oyster (Crassostrea Virginica) Reef Restoration Projects In The Great Bay Estuary, New Hampshire: Planning For The Future, Raymond E. Grizzle, Krystin M. Ward Apr 2016

Assessment Of Recent Eastern Oyster (Crassostrea Virginica) Reef Restoration Projects In The Great Bay Estuary, New Hampshire: Planning For The Future, Raymond E. Grizzle, Krystin M. Ward

PREP Reports & Publications

Current oyster populations in New Hampshire total less than 10% of what they were in the 1980s, and the causal factors for the declines include disease, sedimentation, and human harvest. The two major results from a population ecology perspective have been dramatic losses of oyster shell (the major substrate on which oyster larvae typically settle) as well as juvenile annual recruitment to the remaining reefs. Experimental scale oyster restoration projects addressing these two limitations (substrate and natural recruitment) were initiated in the state in the early 2000s by scientists at the University of New Hampshire (UNH). Since the mid-2000s, the …

"Patterns In The Abundance Of Benthic Algae In Streams", Courtney Wright Apr 2016

"Patterns In The Abundance Of Benthic Algae In Streams", Courtney Wright

Honors Theses

Benthic, microscopic algae are the main drivers of primary productivity in streams. The relationship between the abundance and productivity of benthic algae in streams and lakes and the availability of limiting nutrients, especially soluble reactive phosphorus (SRP), has been extensively studied (reviewed in Allan and Castillo 2007, Larned 2010). However, nearly all of this research has been conducted on the periphyton assemblage found on hard substrates (e.g., stones, wood), while very little work has addressed the factors affecting the abundance of epipelic algae (i.e., the algae associated with depositional (soft) sediments such as sands and silts). One of the few …

Sea Turtle Conservation: Reviewing The Efficacy Of Land- And Sea-Based Management Strategies For Loggerhead (Caretta Caretta) And Leatherback (Dermochelys Coriacea) Sea Turtles, Glenn D. Goodwin

HCNSO Student Capstones

As cosmopolitan species, loggerhead and leatherback turtles are confronted with a multitude of threats as they progress through their respective life stages. These range from depredation and poaching of eggs, hatchlings, and females on nesting beaches, to incidental hooking in pelagic longline fisheries and capture in trawl fisheries. Some threats are species specific on regional scales, though most impact both species. To confront these threats, various conservation strategies have been developed and implemented, including monitoring and caging of nests and changes to hook shape and trawl design. Here, current conservation methods are presented and discussed on a global scale for …
