Elaborate patterns of vertical
zonation provide a range of sunny and cooler conditions for different species111.
Using the University of Miami's Research Vessel F.G. Walton Smith as a platform for daily dives with the NOAA Marine Sanctuaries Foundation's Mohawk ROV, scientists from the U.S. and Cuba specializing in corals, sponges, algae and fish logged thousands of dive notes, underwater photos and video, documenting the geomorphology, biological
zonation and diversity of marine organisms.
«We hope this tool, which displays
zonation of carbohydrate and nitrogen metabolism, in addition to drug detoxification and alcohol degradation, will improve our ability to understand and predict the effects of toxins and new drugs on the liver.»
«Since there is this high climatic
zonation in the tropics and narrow thermal tolerances, there are more opportunities for populations to become divergent and isolated, which is what you need for speciation to happen,» Gill explained.
Notably, both in hphep cells and enhanced hiPS - HEP cultures, only a subset of hepatocytes is strongly stained for glycogen storage — again in agreement with the metabolic
zonation observed in the liver lobe (Figure 3, Panel A).

zonation and disease of the liver.
Notably, both in hphep cells and the enhanced hiPS - HEP cultures, only a subset of hepatocytes is strongly stained for glycogen storage (shown by Periodic acid - Schiff staining, below)-- again in agreement with the metabolic
zonation observed in the liver lobe.
REEF
ZONATION: A trip from west (lagoon side) to east (ocean side) across the Belizean reef complex will reveal a distinct
zonation of substrates and organisms that reflect the subtle environmental changes due to water depth and prevailing wave and current regimes which affect temperature, salinity, light, sedimentation and mechanical stress.
