Dimethyl sulfide triggers search behavior in copepods
The oceans are nutritionally dilute, and finding food is a major challenge for many zooplanktonic predators. Chemodetection is necessary for successful preycapture, but little is known about the infochemicals involved in the interaction between herbivorous copepods and their phytoplankton prey. We used females of Temora longicornis to investigate chemodetection of dimethyl sulfide (DMS) in this...
متن کاملBioaccumulation of polonium-210 in marine copepods
210Po, a naturally occurring radioisotope that is ubiquitous in seawater, is especially enriched in proteinaceous tissues of marine organisms and may therefore be useful as a tracer of organic carbon flux in marine systems. Due in part to its biomagnification in marine food chains, 210Po provides the largest radiation dose to any organism under natural conditions. To better understand the exten...
متن کاملEvolution of bioluminescence in marine planktonic copepods.
Copepods are the dominant taxa in zooplankton communities of the ocean worldwide. Although bioluminescence of certain copepods has been known for more than a 100 years, there is very limited information about the structure and evolutionary history of copepod luciferase genes. Here, we report the cDNA sequences of 11 copepod luciferases isolated from the superfamily Augaptiloidea in the order Ca...
متن کاملPhysical constraints of chemoreception in foraging copepods
The small-scale spatial and temporal dynamics of phycosphere-sized chemical signals entrained within the feeding current of copepods is quantified here by combining flow visualization techniques with electrochemical technology (IVEC-10). Using the 30-mm electrochemical probe sampling at 50 Hz and the velocity gradients created by two marine copepods, we evaluated how odor deformation improves t...
متن کاملJustifying Investments in It
Traditional accounting techniques such as return on investment and net present value are often used when deciding investments in information technology. We examined both academic and trade literature to determine the utility of such techniques and to recognize alternatives. Findings reveal that this survey is needed and is important for information systems managers facing heightened scrutiny of...
