Limulus In The Limelight: Exploring An Ancient Species, John Tanacredi Ph.D. 2018 Molloy College

Limulus In The Limelight: Exploring An Ancient Species, John Tanacredi Ph.D.

Dr. John T. Tanacredi

In an era when sports numbers shatter historical ceilings (especially in baseball) and fall by the wayside like fall leaves, a most enduring record of life continues to crawl along emerging from the sea early each spring pronouncing their incredible "record" of existences... over 350 million years. Now there is a number that even the rarified air of baseball salaries can admire. Yet, today the remarkable sea creature which endured over 100 million years of dramatically changing earth history prior to the existence of the dinosaurs, and which is comprised of only four species globally, is being tested for its ...


Rotating Biological Contractors As An Effective Removal System Of Waste Petroleum Hydrocarbons From Untreated Wastewaters, John Tanacredi Ph.D., R. C. Cardenas 2018 Molloy College

Rotating Biological Contractors As An Effective Removal System Of Waste Petroleum Hydrocarbons From Untreated Wastewaters, John Tanacredi Ph.D., R. C. Cardenas

Dr. John T. Tanacredi

A staged, partially submerged rotating biological disk system was assessed to determine its performance in the reduction of detectable concentrations of polynuclear aromatic hydrocarbons (PAH0 attributable to waste crankcase oils (WCCO) in wastewater effluent. Results indicate that such biological systems for the removal of WCCO aromatic hydrocarbons may be a viable alternative to secondary treatment systems commonly being employed.


Managing Birds And Controlling Aircraft In The Kennedy Airport–Jamaica Bay Wildlife Refuge Complex: The Need For Hard Data And Soft Opinions, John Tanacredi Ph.D., Kevin Brown, R. Michael Erwin, Milo E. Richmond, P A. Buckley, Dave Avrin 2018 Molloy College

Managing Birds And Controlling Aircraft In The Kennedy Airport–Jamaica Bay Wildlife Refuge Complex: The Need For Hard Data And Soft Opinions, John Tanacredi Ph.D., Kevin Brown, R. Michael Erwin, Milo E. Richmond, P A. Buckley, Dave Avrin

Dr. John T. Tanacredi

During the 1980s, the exponential growth of laughing gull (Larus atricilla) colonies, from 15 to about 7600 nests in 1990, in the Jamaica Bay Wildlife Refuge and a correlated increase in the bird-strike rate at nearby John F. Kennedy International Airport (New York City) led to a controversy between wildlife and airport managers over the elimination of the colonies. In this paper, we review data to evaluate if: (1) the colonies have increased the level of risk to the flying public; (2) on-colony population control would reduce the presence of gulls, and subsequently bird strikes, at the airport; and (3 ...


Petroleum Hydrocarbons From Effluents: Detection In Marine Environment, John T. Tanacredi Ph.D. 2018 Molloy College

Petroleum Hydrocarbons From Effluents: Detection In Marine Environment, John T. Tanacredi Ph.D.

Dr. John T. Tanacredi

The marine environment has become the primary disposa ground for an increasing quantity of petroleum wastes. Mushrooming demands for petroleum products and the lack of economic incentive to recycle waste oil will increase the concentrations of detrimental petroleum hydrocarbons in the marine environment

Although a continuous, low-level discharge of waste petroleum hydrocarbons into the marine environment may not be as dramatic as a major oil spill, the consequences could be more devastating over an extended period. As noted by Blumer, earlier interpretations of the environmental effects of oil must not be reevaluated in the light of recent evidence of its ...


Liver Lesions In Winter Flounder (Pseudopleuronectes Americanus) From Jamaica Bay, New York: Indications Of Environmental Degradation, John T. Tanacredi Ph.D., Thomas P. Augspurger, Roger L. Herman, Jeff S. Hatfield 2018 Molloy College

Liver Lesions In Winter Flounder (Pseudopleuronectes Americanus) From Jamaica Bay, New York: Indications Of Environmental Degradation, John T. Tanacredi Ph.D., Thomas P. Augspurger, Roger L. Herman, Jeff S. Hatfield

Dr. John T. Tanacredi

Liver sections of winter flounder (Pseudopleuronectes americanus) collected from Jamaica Bay and Shinnecock Bay, New York, in 1989, were examined microscopically to determine the pervasiveness of liver lesions observed previously in Jamaica Bay winter flounder. Neoplastic lesions were not detected in fish from Jamaica Bay or the Shinnecock Bay reference site. Twenty-two percent of Jamaica Bay winter flounder examined (n=103) had unusual vacuolization of hepatocytes and biliary pre-ductal and ductal cells (referred to hereafter as the vacuolated cell lesion). The lesion, identical to that found in 25% of Jamaica Bay winter flounder examined in 1988, has previously been identified ...


Questioning Ecosystem Assessment And Restoration Practices In A Major Urban Estuary: Perpetuating Myths Of Degradation In Spite Of Facts, John T. Tanacredi Ph.D., Martin P. Schreibman, Kevin McDonnell 2018 Molloy College

Questioning Ecosystem Assessment And Restoration Practices In A Major Urban Estuary: Perpetuating Myths Of Degradation In Spite Of Facts, John T. Tanacredi Ph.D., Martin P. Schreibman, Kevin Mcdonnell

Dr. John T. Tanacredi

The Jamaica Bay ecosystem is a dichotomy. It encompasses more than 12,000 acres of coastal estuarine marshes and an ecological diversity rivaling any coastal environment in the world. It is considerably altered, and is affected by a variety of ecological insults directly related to the fact that more than 14 million people live in its vicinity. Environmental protection institutions responded to the challenge of protecting the bay, surrounding wetlands and recreational benefits by addressing the increasing load of contaminants into the ecosystem. Billions of dollars have been spent during the past five decades on restoration attempts, including upgrading wastewater ...


Phytosociological Analysis Of Restored And Managed Grassland Habitat Within An Urban National Park, John T. Tanacredi Ph.D., Andrew M. Greller, Celestine Durando, Leslie F. Marcus, D. Siril A. Wijesundara, Michael D. Byer, Robert Cook 2018 Molloy College

Dr. John T. Tanacredi

Floyd Bennett Field (FBF), 579 ha in extent, is a division of Gateway National Recreation Area. It is the site of a former airfield, constructed by filling salt marshes with dredged materials. Except for the portion known locally as the “North Forty,” all sections of FBF have been cut over to maintain low vegetation. A grassland management plan (GRAMP) for 165 ha was initiated in 1986, to maintain habitats for open-country birds. Over the next few years, encroaching woody vegetation was removed manually and mechanically from the management area. Since then, it has been maintained as a grassland and receives ...


Naphthalenes Associated With Treated Wastewater Effluents In An Urban National Wildlife Refuge, John T. Tanacredi Ph.D. 2018 Molloy College

Naphthalenes Associated With Treated Wastewater Effluents In An Urban National Wildlife Refuge, John T. Tanacredi Ph.D.

Dr. John T. Tanacredi

Our coastal enviornments have become the invariable recipient of petroleum and petroleum wastes. Demands for petroleum products coupled with a lack of economic incentive to recycle waste oil, will increase the probability of greater concentrations of petroleum derived hyrdrocarbons entering our estuaries (CEQ Report, 1983).


Biodepuration Of Polynuclear Aromatic Hydrocarbons From A Bivalve Mollusk, Mercenaria Mercenaria L, John T. Tanacredi Ph.D., Raul R. Cardenas 2018 Molloy College

Biodepuration Of Polynuclear Aromatic Hydrocarbons From A Bivalve Mollusk, Mercenaria Mercenaria L, John T. Tanacredi Ph.D., Raul R. Cardenas

Dr. John T. Tanacredi

Mercenaria mercenaria, exposed in vitro for 48 h to nine parent polynuclear aromatic hydrocarbons (PAHs) found in waste crankcase oil (WCCO) and analysed by multiparametric analysis over a 45- day depuration period in an activated carbon filtration aquaria system, did not depurate PAHs, but rather maintained them at detectable levels. Uptake of PAHs was shown to be directly related to clam weight. A cluster analysis of empirical results reaffirmed a biostabilization in PAH groupings in clam tissue over a 45-day depuration period and exhibited no evidence of a decreasing trend in total PAHs when subjected to ANOVA. Due to the ...


Changes In Reproductive Morphology And Physiology Observed In The Amphipod Crustacean, Melita Nitida Smith, Maintained In The Laboratory On Polluted Estuarine Sediments, John T. Tanacredi Ph.D., B. Borowsky, P. Aitken-Ander 2018 Molloy College

Changes In Reproductive Morphology And Physiology Observed In The Amphipod Crustacean, Melita Nitida Smith, Maintained In The Laboratory On Polluted Estuarine Sediments, John T. Tanacredi Ph.D., B. Borowsky, P. Aitken-Ander

Dr. John T. Tanacredi

An earlier study showed that the amphipod crustacean Melita nitida Smith maintained on sediments dosed with waste crankcase oil developed physiological and morphological abnormalities. Most notably, mature females developed abnormal setae along the edges of their brood plates. The present study was conducted to determine whether similar abnormalities might be induced in animals maintained on polluted field sediments containing petroleum by-products among other toxic substances. In the laboratory, heterosexual pairs were maintained on three sediments taken from Jamaica Bay (New York) plus one control sediment and one toxic substratum (Ulva lactuca (L.) thalli). The results mirrored the results of the ...


Characterization Of Polycyclic Aromatic Hydrocarbons (Pahs) By The Kinetics Of Depuration In Bivalve Molluscs, Mercenaria Mercenaria, John T. Tanacredi Ph.D., C Sato, H Kim 2018 Molloy College

Characterization Of Polycyclic Aromatic Hydrocarbons (Pahs) By The Kinetics Of Depuration In Bivalve Molluscs, Mercenaria Mercenaria, John T. Tanacredi Ph.D., C Sato, H Kim

Dr. John T. Tanacredi

The objectives of this study were to examine depuration aspects of polycyclic aromatic hydrocarbons (PAHs) in a hard-shell clam Mercenaria mercenaria, and to characterize PAHs by the depuration kinetics. In this investigation, clams were exposed to artificial sea water containing a mixture of eight PAHs (i.e., naphthalene, fluorene, phenanthrene, flouranthene, pyrene, benz[a]anthracene, chrysene, benzo[a]pyrene) for 48 hours. The clams were then transferred into clean (PAH-free) artificial seawater for release, and sampled at predetermined intervals. The target PAHs were extracted from the clam tissue and quantified by a gas chromatograph equipped with a capillary glass column ...


Habitat Use Of Sympatrically Nesting Fish Crows And American Crows, John Tanacredi Ph.D., Brook Lauro 2018 Molloy College

Habitat Use Of Sympatrically Nesting Fish Crows And American Crows, John Tanacredi Ph.D., Brook Lauro

Dr. John T. Tanacredi

We examined habitat use of sympatric Fish Crows (Corvus ossifragus) and American Crows (C. brachyrhynchos) nesting in the vicinity of waterbird breeding locations at the Rockaway Peninsula, New York City. Fish Crows nested significantly more often at natural habitats, including coastal dunes and salt marsh islands; American Crows nested significantly more often at residential and recreational areas. In regard to potential foraging areas, Fish Crows nested closer to waterbird colonies and to the water's edge while American Crows nested closer to a garbage source and to lawns. Fish Crows nested significantly more often in deciduous trees that were native ...


An Examination Of Predatory Pressures On Piping Plovers Nesting At Breezy Point, New York, John Tanacredi Ph.D., Brook Lauro 2018 Molloy College

An Examination Of Predatory Pressures On Piping Plovers Nesting At Breezy Point, New York, John Tanacredi Ph.D., Brook Lauro

Dr. John T. Tanacredi

This study examines predatory threats to Piping Plovers (Charadrius melodus) nesting at Breezy Point, Gateway National Recreation Area, New York. Several methods used include: 1) an evaluation of reproductive success data with documentation of predation to eggs and chicks, 2) predator surveys, and 3) an artificial nest study. The range of breeding pairs nesting from 1988-1996 was 11-19, with an average of 15.8 (SE ± 0.79) pairs/season. The average number of eggs hatched and chicks fledged per year for pairs was 2.2 ± 0.23 and 0.8 ± 0.16 respectively. Reasons for egg losses often went undetected ...

Mitotic Instability In Triploid And Tetraploid One-Year-Old Eastern Oyster, Crassostrea Virginica, Assessed By Cytogenetic And Flow Cytometry Techniques, Jt De Sousa, Sk Allen, Bm Wolfe, Jm Moss

VIMS Articles

For commercial oyster aquaculture, triploidy has significant advantages. To produce triploids, the principal technology uses diploid x tetraploid crosses. The development of tetraploid brood stock for this purpose has been successful, but as more is understood about tetraploids, it seems clear that chromosome instability is a principal feature in oysters. This paper is a continuation of work to investigate chromosome instability in polyploid Crassostrea virginica. We established families between tetraploids-apparently stable (non-mosaic) and unstable (mosaic)-and normal reference diploids, creating triploid groups, as well as tetraploids between mosaic and non-mosaic tetraploids. Chromosome loss was about the same for triploid juveniles ...


Crayfish Harvesting Practices In The Southern Atchafalaya River Basin: Quantitative And Qualitative Assessment Of Harvester Techniques And Hydrologic Connectivity Influence On Harvesting Strategies, Ivan A. Vargas-Lopez 2018 Louisiana State University and Agricultural and Mechanical College

Crayfish Harvesting Practices In The Southern Atchafalaya River Basin: Quantitative And Qualitative Assessment Of Harvester Techniques And Hydrologic Connectivity Influence On Harvesting Strategies, Ivan A. Vargas-Lopez

LSU Master's Theses

Fisheries produce important impacts around the world through the exploitation of a wide range of species. In Louisiana, crayfish is the most emblematic crustacean and supports a multi-million industry based on pond culture and harvest from natural habitats. Although the economic value (USD) of wild-harvested crayfish has decreased from 10% to 3% of total crayfish value from 2013 to 2015, wild harvested crayfish are highly desired by many consumers and have a strong socio-cultural importance in Louisiana and other Gulf of Mexico coastal regions. This project evaluated harvesting practices by: 1) field observation and mapping of harvest sites in southwestern ...

Insights Into Teleost Sex Determination From The Seriola Dorsalis Genome Assembly, Catherine M. Purcell, Arun S. Seetharam, Owyn Snodgrass, Sofia Ortega-García, John R. Hyde, Andrew J. Severin

Office of Biotechnology Publications

Background: The assembly and annotation of a genome is a valuable resource for a species, with applications ranging from conservation genomics to gene discovery. Genomic resource development is especially important for species in culture, such as the California Yellowtail (Seriola dorsalis), the likely candidate for the establishment of commercial offshore aquaculture production in southern California. Genomic resource development for this species will improve the understanding of sex and other phenotypic traits, and allow for rapid increases in genetic improvement for and economic gain in culture production.

Results: We describe the assembly and annotation of the S. dorsalis genome, and present ...
