Oceanic diel vertical migration (DVM) constitutes the daily movement of various mesopelagic organisms migrating vertically from depth to feed in shallower waters and return deeper water during day. Accurate classification taxa that participate DVM remains non-trivial, there can be discrepancies between methods. DEEPEND consortium (www.deependconsortium.org) scientists have been characterizing diversity trophic structure pelagic communities northern Gulf Mexico (nGoM). Profiling has included...
An HPLC method was developed for the quantification of biogenic amines in insect hemolymph. The major challenge analysis is that a typical sample only contains few hundred pictograms amine. A C18 column and electrochemical detection used. eluent an aqueous 0.06 M phosphate buffer (pH- 6.7) mixed with 10-15% methanol ion-pairing reagent. With this method, can be detected at picogram levels. However, there are hundreds compounds biological fluid and, some cases, another electro-active species...
Seascape genomics provides a powerful framework to evaluate the presence and strength of environmental pressures on marine organisms, as well forecast long term species stability under various perturbations. In highly productive North Pacific, forage fishes, key trophic links across ecosystems, are also contending with rapidly warming climate litany associated oceanographic changes (e.g., in salinity, dissolved oxygen, pH, primary production, etc.). These can place substantial selective...
