Abstract

Interactions between predators and prey species are arguably the most pervasive and important events in ecology. Predators have strong effects on the distribution and abundance of prey in virtually all environments. In the long-term, it is therefore hardly surprising that selective mortality imposed by predators has shaped a wide array of prey behaviors that ...

The Role Of Seasonality, Seaweed Traits, And Seaweed-Herbivore Interactions In Nutrient Cycling In The Southern Gulf Of Maine, Valerie Catlin Perini

Biology Master's Theses

Environmental fluctuations associated with both natural events and anthropogenic impacts can appreciably alter the functioning of ecosystems. For example, in the Gulf of Maine, there is substantial spatial and temporal variation in availability of nutrients that fuel primary production. Macroalgae are important primary producers in intertidal and shallow benthic habitats, and they play essential roles in absorbing nutrients (e.g., inorganic C, N, and P) and mediating their availability (e.g., as organic C, N, and P) to the communities that they support. The ability of macroalgae to take up nutrients depends on nutrient availability. However, sometimes a nutrient in ...

Aerobic Degradation Of Α-, Β-, Γ-Hexachlorocyclohexane By Narragansett Bay Bacterioplankton, Ian M. Rambo

Senior Honors Projects

Hexachlorocyclohexanes (HCHs) are a family of chlorinated organic compounds that were previously used as agricultural insecticides. HCHs are recognized as persistent organic pollutants due to their toxicity, recalcitrant properties, and tendency to bioaccumulate in food webs. Although HCH was first synthesized in 1825, its use was not widespread until the discovery of the insecticidal activity of the γ-HCH isomer in 1942. γ-HCH and its toxic waste isomers α-HCH and β-HCH were banned from production and use by the United Nations in 2009, yet these chemicals still present environmental problems due to their persistence in soils and surface waters. HCHs continue ...

Isolation And Partial Characterization Of Bioactive Fucoxanthin From Himanthalia Elongata Brown Seaweed: A Tlc-Based Approach, Gaurav Rajauria, Nissreen Abu-Ghannam

Articles

Seaweeds are important sources of carotenoids, and numerous studies have shown the beneficial effects of these pigments on human health. In the present study, Himanthalia elongata brown seaweed was extracted with a mixture of low polarity solvents, and the crude extract was separated using analytical thin-layer chromatography (TLC).The separated compounds were tested for their potential antioxidant capacity and antimicrobial activity against Listeria monocytogenes bacteria using TLC bioautography approach. For bio-autography, the coloured band on TLC chromatogram was visualized after spraying with DPPH and triphenyltetrazolium chloride reagents which screen antioxidant and antimicrobial compounds, respectively, and only one active compound was ...

Assessment Of Sea Lice Infestations On Wild Fishes Of Cobscook Bay, Alexander Jensen

Honors College

Sea lice are ectoparasitic copepods on fishes and can negatively impact aquaculture operations. Little work on sea lice, specifically Lepeophtheirus salmonis and Caligus elongatus, has occurred in the northwest Atlantic. This project characterized sea lice infestations on wild fishes in Cobscook Bay during 2012. Trawling, seine netting, and fyke netting occurred from March to November. Netting sites were selected to sample the bay’s three regions: Outer, Central, and Inner Bay. Visual examinations of fish were used to identify wild hosts and characterize sea lice life stage abundances, attachment locations, and infection prevalence and intensity. DNA sequencing was used to ...

Thermal And Spatial Tracking Of Inter-Nesting Loggerhead Turtles (Caretta Caretta) In Kyparissia Bay, Greece, Thomas F. Backof, Stephen J. Morreale, Thomas E. Riggall

IPFW Student Research and Creative Endeavor Symposium

Loggerhead sea turtles are globally endangered cold blooded reptiles. As with all sea turtles, they return to the same beach to nest, making each distinct beach and population important for species survival. Time spent between nesting attempts is referred to as the inter-nesting period and is a short but vital part of a turtle’s life. As turtles are able to behaviorally thermoregulate, temperature is thought to be an important aspect of inter-nesting location. Determining where a turtle spends her inter-nesting period is an important research topic for the conservation of the species. Kyparissia Bay, Peloponnese, Greece is the second ...

Preliminary Satellite Telemetry Of Eastern Pacific Green Turtles Nesting On Playa, Chelsea Clyde-Brockway

IPFW Student Research and Creative Endeavor Symposium

The eastern pacific green turtle (Chelonia mydas agassizi) is endangered and nests along the Pacific coast of Central America. Understanding where turtles are going when they are not nesting on the beach can help us to better preserve the resources and ocean habitats that are important to these species. There are three characteristic behaviors of adult sea turtles when in the water: they are either migrating to or from foraging areas, foraging, or spending time in off-shore habitats in between depositing clutches of eggs. I studied post nesting migrations and interesting movements in eastern pacific green turtles nesting on Playa ...

Recent Mass Mortality Of Strongylocentrotus Purpuratus (Echinodermata: Echinoidea) At Malibu And A Review Of Purple Sea Urchin Kills Elsewhere In California, Gordon Hendler

Bulletin of the Southern California Academy of Sciences

Mass mortalities of intertidal purple sea urchins, Strongylocentrotus purpuratus occurred at Malibu Lagoon State Beach, California, in 2010 and 2011. Both events followed the first heavy rain of the season, and coincided with an illegal breaching of the lagoon. Osmotic shock from low-salinity lagoon water, the likely cause of death, may have acted jointly with stress from exposure during especially low tides. Comparable die-offs of purple sea urchins have occurred at other localities after exposure to brackish water or thermal shock. Annually recurring lagoon ruptures at Malibu, combined with predation by western gulls, can have a profound impact on the ...

Fishery-Dependent Estimates Of Growth, Development, And Reproduction In Gulf Corvina (Cynoscion Othonopterus), Katie E. Gherard, Brad E. Erisman, Octavio Aburto-Oropeza, Kirsten Rowell, Larry G. Allen

Bulletin of the Southern California Academy of Sciences

Gulf corvina, Cynoscion othonopterus, is a vital component of commercial fisheries in the northern Gulf of California, but a lack of information on life history parameters have thus far prevented a comprehensive stock assessment. In this project, 530 specimens of Gulf corvina were collected from commercial gill net fisheries in the Colorado River Delta region in Sonora, Mexico, to characterize population structure, age and growth patterns, age and size at sexual maturity and batch fecundity of Gulf corvina. Fish ranged from 145 mm to 1013 mm in total length and from 1 to 8 years of age. Von Bertalanffy growth ...

Design Of An Underwater Video And Gps Mapping System For The Exploration Of Streambed Aquatic Populations, William Barbour

EURēCA: Exhibition of Undergraduate Research and Creative Achievement

This design project was initiated due to the need for an underwater video mapping system optimized for exploration along the streambed or riverbed and under rocks. Such a system would be used for population mapping of fish and other aquatic species. The system also needed to incorporate global positioning system data with the visual data. The current prototype successfully fulfills the requirements for underwater practicality and visual and GPS data collection. It incorporates a compact waterproof camera with Sony lens, two Fenix high-intensity waterproof flashlights for illumination, a handheld DVR for recording video, and a Garmin 60CSx GPS unit. The ...

Economic Efficiency In Fisheries And Aquaculture, Paul Molyneaux

The Catch

Reflection of the author as a worker looking to make the best use of his time and energy. His innate understanding of the principles of ecological economics followed by exposure to the discipline’s advancing theories leads to a revelation regarding the backwards logic of fisheries and aquaculture policy thus far, and the decline in real seafood production.Along with many others, Molyneaux looks to ecological economics to create a new paradigm for sustainable fisheries.

Assessment Of Genetic Connectivity And Potential Management Plans For The Coral Reef Ecosystems Of Guna Yala, Panama, Molly Mcentee

Independent Study Project (ISP) Collection

Genetic connectivity between three populations of the common reef sea urchin, Echinometra lucunter located in fringing reefs off the islands of Ukuptupu, Wichupwala and Porvenir in western Guna Yala was analyzed to give insight into population distribution and the most effective conservation management plans for the area. The reefs of Guna Yala are facing many threats on a global or regional scale including global warming, ocean acidification, sea level rise, disease and severe storms. On a local level, increasing stress is being placed on these reef ecosystems from human activity including coral mining, overfishing, and pollution. In order to prevent ...

Dietary Contribution Of Polychlorinated Biphenyl Contaminated Ulva To Fundulus Heteroclitus In The New Bedford Harbor, Ma, Superfund Site, Elizabeth Sly

Biology Master's Theses

Macroalgal blooms are associated with a wide range of negative consequences impacting the growth and survival of primary producers and benthic consumers, but are generally not viewed as serious threats to higher trophic level consumers. A recently discovered polychlorinated biphenyl (PCB) contaminated Ulva bloom located in the New Bedford Harbor (NBH), MA, Superfund site challenges this idea, but its potential to increase the bioavailability of PCBs to the upper NBH food web has not previously been evaluated. In this investigation, the dietary contribution of Ulva to the common NBH mid-trophic consumer Fundulus heteroclitus was assessed between fall 2011 and fall ...
