Community Structure And Production Of The Macrobenthos On Four Artificial Reefs In The Mississippi Sound In Relation To Substrate And Profile Type, Patrick Daniel Gillam 2016 University of Southern Mississippi

Community Structure And Production Of The Macrobenthos On Four Artificial Reefs In The Mississippi Sound In Relation To Substrate And Profile Type, Patrick Daniel Gillam

Master's Theses

In recent years, the Mississippi Department of Marine Resources (DMR) has made a concerted effort to enhance its coastal fishery resources by creating artificial reefs. Through this effort, 73 nearshore reefs have been created across the MS coast. Different substrate types used to construct MS artificial reefs include oyster shell and cement rubble. Two types of reef architecture used include high profile breakwater and low profile submerged structures. This study compared the benthic biota associated with oyster shell and cement rubble substrates among four artificial reefs representing high and low profile structures in summer 2011. Colonized benthic biota were quantified ...

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

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

Student Research Day 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 ...


Ocean Acidification And Predator-Prey Relations: Correlating Disruption Of Predator Avoidance With Chemosensory Deficits, Alexandra FW Sidun 2016 Chapman University

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

Student Research Day 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 ...


Bioavailability Of Dissolved Organic Matter In The North Inlet Estuary, Andrew Mason Gaines Banks 2016 University of South Carolina - Columbia

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

Theses and Dissertations

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 ...


A Comparative Study Of Isolation In Headwater Fishes, Bjorn Victor Schmidt 2016 University of Southern Mississippi

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 ...


Retention Effects Of An Experiential Pedagogical Approach, Kelsea E. Adams 2016 University of Rhode Island

Retention Effects Of An Experiential Pedagogical Approach, Kelsea E. Adams

Senior Honors Projects

The quality and nature of delivery of education, especially at the K12 level is a major focus of the education reform movement. As an aspiring teacher, I am interested in developing a personal understanding of the efficacy of different modes of delivery. A large body of studies has examined the differences between experiential learning versus traditional classroom learning as well as effects on student retention. Traditional classroom learning involves literary texts, PowerPoint presentations and teacher-centered learning. In contrast, experiential learning is a hands-on, real world experience that provides students with an environment to expand their critical thinking skills and apply ...


Examining The Effectiveness Of Coral Restoration Nurseries, Grace Hanson 2016 University of Rhode Island

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 ...


Seed Collection And Germination Strategies For Common Wetland And Coastal Sage Scrub Species In Southern California, Michelle L. Barton, Ivan D. Medel, Karina K. Johnston, Christine R. Whitcraft 2016 California State University Long Beach

Seed Collection And Germination Strategies For Common Wetland And Coastal Sage Scrub Species In Southern California, Michelle L. Barton, Ivan D. Medel, Karina K. Johnston, Christine R. Whitcraft

Bulletin of the Southern California Academy of Sciences

There is a need for a consolidated source of information on native vegetation seed collection and germination strategies in southern California. Published literature on these methods is often experimental, species-specific, and widely scattered throughout online and print media. Planting and restoration strategies may need to be site-specific; however, similar methodological approaches are often utilized allowing for the development of general strategies for seed collection, storage, and germination methods. A better understanding of species-specific seed attributes and growth processes will help restoration ecologists collect high-quality, viable seed, thereby increasing the potential success of the restored vegetation community by reducing plant mortality ...


The Return Of The King Of The Kelp Forest: Distribution, Abundance, And Biomass Of Giant Sea Bass (Stereolepis Gigas) Off Santa Catalina Island, California, 2014-2015., Parker H. House, Brian L.F. Clark, Larry G. Allen 2016 California State University - Northridge

The Return Of The King Of The Kelp Forest: Distribution, Abundance, And Biomass Of Giant Sea Bass (Stereolepis Gigas) Off Santa Catalina Island, California, 2014-2015., Parker H. House, Brian L.F. Clark, Larry G. Allen

Bulletin of the Southern California Academy of Sciences

It is rare to find evidence of top predators recovering after being negatively affected by overfishing. However, recent findings suggest a nascent return of the critically endangered giant sea bass (Stereolepis gigas) to southern California. To provide the first population assessment of giant sea bass, surveys were conducted during the 2014/2015 summers off Santa Catalina Island, CA. Eight sites were surveyed on both the windward and leeward side of Santa Catalina Island every two weeks from June through August. Of the eight sites, three aggregations were identified at Goat Harbor, The V’s, and Little Harbor, CA. These three ...

Nudibranch Range Shifts Associated With The 2014 Warm Anomaly In The Northeast Pacific, Jeffrey Hr Goddard, Nancy Treneman, William E. Pence, Douglas E. Mason, Phillip M. Dobry, Brenna Green, Craig Hoover

Bulletin of the Southern California Academy of Sciences

Abstract.—The Northeast Pacific Ocean was anomalously warm in 2014, despite ENSO-neutral conditions in the tropical Pacific. We documented northern range shifts associated with this anomaly for 30 species of nudibranchs and other shallow-water, benthic heterobranch gastropods from southern California to southern Oregon. Nine of these (Placida cremoniana, Trapania velox, Doriopsilla fulva, Janolus anulatus, J. barbarensis, Flabellina cooperi, Anteaeolidiella chromosoma, A. oliviae, and Noumeaella rubrofasciata) were recorded from new northernmost localities, while the remainder were found at or near northern range limits established mainly during past El Niño events. All 30 species have planktotrophic larval development, and six were observed ...
