A competitive ELISA to detect brevetoxins from Karenia brevis (formerly Gymnodinium breve) in seawater, shellfish, and mammalian body fluid.
We developed a competitive enzyme-linked immunosorbent assay (ELISA) to analyze brevetoxins, using goat anti-brevetoxin antibodies obtained after immunization with keyhole limpetExpand
Multiple defensive roles for triterpene glycosides from two Caribbean sponges
Abstract. Despite their high nutritional value and a lack of physical defenses, most marine sponges appear to be minimally affected by predators, competitors, and fouling organisms, possibly due toExpand
Does the red tide dinoflagellate Karenia brevis use allelopathy to outcompete other phytoplankton
Monospecific blooms of phytoplankton can disrupt pelagic communities and negatively affect human health and economies. Interspecific competition may play an important role in promoting blooms, and soExpand
Macroalgal terpenes function as allelopathic agents against reef corals
During recent decades, many tropical reefs have transitioned from coral to macroalgal dominance. These community shifts increase the frequency of algal–coral interactions and may suppress coralExpand
Effects of harmful algal blooms on competitors: Allelopathic mechanisms of the red tide dinoflagellate Karenia brevis
Because competitive interactions may have led to adaptations enabling bloom-forming phytoplankton to dominate pelagic communities, we explored the allelopathic effects of one red tide dinoflagellate,Expand
Seaweed resistance to microbial attack: A targeted chemical defense against marine fungi
Pathogenic microbes can devastate populations of marine plants and animals. Yet, many sessile organisms such as seaweeds and sponges suffer remarkably low levels of microbial infection, despiteExpand
Desorption electrospray ionization mass spectrometry reveals surface-mediated antifungal chemical defense of a tropical seaweed
Organism surfaces represent signaling sites for attraction of allies and defense against enemies. However, our understanding of these signals has been impeded by methodological limitations that haveExpand
Chemically mediated competition between microbes and animals: microbes as consumers in food webs.
Microbes are known to affect ecosystems and communities as decomposers, pathogens, and mutualists. However, they also may function as classic consumers and competitors with animals if they chemicallyExpand
New fish-killing alga in coastal Delaware produces neurotoxins.
Ten fish mortality events, involving primarily Atlantic menhaden, occurred from early July through September 2000 in several bays and creeks in Delaware, USA. Two events involved large mortalitiesExpand
Chemical defense of the red tide dinoflagellate Karenia brevis against rotifer grazing
In order to test whether phytoplankton such as the red tide dinoflagellate Karenia brevis negatively affect rotifer grazers and what mechanisms are involved in these interactions, we conductedExpand
