Chemoattraction to dimethylsulfoniopropionate throughout the marine microbial food web.
Phytoplankton-produced dimethylsulfoniopropionate (DMSP) provides underwater and atmospheric foraging cues for several species of marine invertebrates, fish, birds, and mammals. However, its role in the chemical ecology of marine planktonic microbes is largely unknown, and there is evidence for contradictory functions. By using microfluidics and image analysis of swimming behavior, we observed ...

Resource patch formation and exploitation throughout the marine microbial food web.
Exploitation of microscale (microm-mm) resource patches by planktonic microorganisms may influence oceanic trophodynamics and nutrient cycling. However, examinations of microbial behavior within patchy microhabitats have been precluded by methodological limitations. We developed a microfluidic device to generate microscale resource patches at environmentally realistic spatiotemporal scales, and...
متن کاملThe neuroecology of dimethyl sulfide: a global-climate regulator turned marine infochemical.
Information transfer influences food-web dynamics in the marine environment, but infochemicals involved in these processes are only beginning to be understood. Dimethylsulfoniopropionate (DMSP) is produced by phytoplankton and other marine algae, and has been studied primarily in the context of sulfur cycling and regulation of global climate. My laboratory has been investigating DMSP and its br...
متن کاملThe possibility of occurrence of the phenomenon “fishing down marine food webs” in the coastal waters of Hormozgan Province (north of the Persian Gulf and Oman Sea)
We examined the temporal trend in mean trophic level (mTL), trophic category landing (TrC) and landing profile (LP) of the exploited marine community (49 species) in the fishing zone of Hormozgan (north of Persian Gulf and Oman Sea) from 2001 to 2011. LP had an increasing trend (r = 0.88, P<0.001), whereas, mTL of the landings showed a significant decrease from 2001 to 2011 (r = -0.69, P<0.05)....
