Unraveling the assembly mechanism is a core research topic of microbial ecology. Abundant and rare communities are crucial for diversity, function host health in given ecosystem, but few studies focused on their strategies. Here, we explored diversity abundant water, shrimp intestine sediment habitats cultural ponds. Our results found that numbers operational taxonomic units (OTUs) (6,003, 4,56...

The diagram showing off-center nested spheres which is traditionally used to illustrate the Doppler effect, misleading and its trigonometric analysis leads errors concerning light, because electromagnetic aberration effects conform a wavefront surface that not sphere but an ellipsoid stretched along trajectory of source. Cartesian polar equations spherical ellipsoidal wavefronts are compared he...
