Journal ArticleDOI
Relationships among water column toxins, cell abundance and chlorophyll concentrations during Karenia brevis blooms
Patricia A. Tester,Damian Shea,Steven R. Kibler,Sabrina M. Varnam,Megan N. D. Black,R. Wayne Litaker +5 more
TL;DR: Data substantiate the use of chlorophyll as a proxy for K. brevis cell abundance as aproxy for brevetoxins during blooms and suggest that growth rates may provide a useful indicator for determining the physiological state of the bloom over time.
Journal ArticleDOI
Airborne detection of ecosystem responses to an extreme event: Phytoplankton displacement and abundance after hurricane induced flooding in the Pamlico-Albemarle Sound System, North Carolina
Patricia A. Tester,Sabrina M. Varnam,Mary E. Culver,David L. Eslinger,Richard P. Stumpf,R. N. Swift,James K. Yungel,Megan N. D. Black,R. Wayne Litaker +8 more
TL;DR: In this article, airborne laser-induced fluorescence measurements were used to detect and monitor ecosystem wide changes in the distribution and concentration of chlorophyll biomass and colored dissolved organic matter in the Pamlico-Albemarle Sound system, North Carolina, U.S., following massive flooding caused by a series of three hurricanes in the late summer of 1999.
Journal ArticleDOI
Modeling phytoplankton abundance in saginaw bay, lake huron: using artificial neural networks to discern functional influence of environmental variables and relevance to a great lakes observing system1
David F. Millie,Gary R. Weckman,Ryan J. Pigg,Patricia A. Tester,Julianne Dyble,R. Wayne Litaker,Hunter J. Carrick,Gary L. Fahnenstiel +7 more
TL;DR: Forecasting initiatives within the developing Great Lakes Observing System may be best served by embedding neural networks in mechanistic models to quantitatively initialize variables, qualitatively delineate conditions for projecting ecological structure, and/or estimate deviations from predictability within mechanistic simulations.
Journal ArticleDOI
Pathogenicity Studies with the Fungi Aphanomyces invadans, Achlya bisexualis, and Phialemonium dimorphosporum: Induction of Skin Ulcers in Striped Mullet
Emilio R. Sosa,Jan H. Landsberg,Yasunari Kiryu,Christy M. Stephenson,Theresa T. Cody,Angela K. Dukeman,Heather P. Wolfe,Mark W. Vandersea,R. Wayne Litaker +8 more
TL;DR: This study fulfilled Koch's postulates and demonstrated that ulcers could be experimentally induced in striped mullet after exposure via injection to secondary zoospores of an endemic Florida strain of Aphanomyces invadans.
Journal ArticleDOI
qPCR assays for Alexandrium fundyense and A. ostenfeldii (Dinophyceae) identified from Alaskan waters and a review of species-specific Alexandrium molecular assays
Mark W. Vandersea,Steven R. Kibler,Scott B. Van Sant,Patricia A. Tester,Kate Sullivan,Ginny L. Eckert,Charlayna A. Cammarata,Kim Reece,Gail P. Scott,Allen R. Place,Kris Holderied,Dominic Hondolero,R. Wayne Litaker +12 more
TL;DR: This study identified the toxic Alexandrium species present in Alaska and developed polymerase chain reaction (PCR) assays for use in screening phytoplankton and sediment samples and identified a suite of species-specific Alexandrium assays that can be recommended for evaluation by the global harmful algal bloom community.
