متن کاملPenguin eggshell membranes reflect homogeneity of mercury in the marine food web surrounding the Antarctic Peninsula.
Remote regions such as the Antarctic have become increasingly important for investigations into far-reaching anthropogenic impacts on the environment, most recently in regard to the global mercury cycle. Spatial patterns of mercury availability in four regions of the Antarctic Peninsula were investigated using three species of sympatrically breeding Pygoscelis penguins as biomonitors. Eggshells...
متن کاملAntarctic marine biology
David K.A. Barnes and Andrew Clarke Primer interfering with the ability of a second species to locate mates. This could be the result of the one species’ calls simply masking those of the other, or it could be that the calls confuse individuals of the second species and cause them to approach heterospecific callers rather than those of their own species. Such signal jamming can also occur withi...
متن کاملChemoattraction 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 ...
