Algal Toxins Alter Copepod Feeding Behavior.
Algal toxins alter copepod feeding behavior.
The researchers studied the behavior of the algal cell Karlodinium veneficum, known as a dinoflagellate and found in estuaries worldwide.
There is now considerable evidence for the rapid evolution of population-specific adaptations in cladocerans such as body size, defensive structures, phototactic behavior, resistance to algal toxins, and parasite resistance[ 7, 10- 12].
We previously reported that exposure to DDT or its metabolite DDE during zebrafish neurodevelopment enhances seizure behavior response to the algal toxin domoic acid after completion of brain maturation, a likely exposure scenario for the CSL population of the Channel Islands (Tiedeken and Ramsdell 2009).
The mathematical model exhibited behavior similar to that described in literature for photosynthetic algal hydrogen production by sulfur-deprived algal cultures.
The body burden of CH3Hg+ reaches an apparent steady state after 12 h in this experiment, although variability at each time point was high, possibly due to feeding behavior, and to variable metal distribution in the algal food source.
Considering the varying flocculant concentrations needed to floc the different algal species, the hypothesis that related species (Chlorophyceae) show similar flocculation behavior cannot be positively proved.
We assessed the distribution and behavior of herbivorous fishes in Moorea, French Polynesia in coral and algal turf-dominated fringing reef sites.
Remarkably, we found a similar behavior of telomerases during PEG purification from protein extracts in various algal groups, suggesting their similar biochemical properties.
Thermogravimetry (TG/DTA) of the wet micro algal biomass, micro algal feed stock and bio-oil has also been performed to analyze their thermal behavior.
