This preliminary study indicates, for each of the United States and Canadian provinces, the leading physical features, meteorological conditions, biological zones, summarises the associated flora and fauna, and mentions the areas suitable for Nature reserves.
Macrobenthic communities are known to show zonation patterns across sandy beaches and many studies highlighted the existence of three biological zones.
Ecological restoration (reconstruction) must have a scientific basis on the biological zones of vegetation mainly controlled by the climatic factors (humidity and thermal conditions) and the sere of it.
At genus level, there were 3 differential abundant taxa (i.e. uncultured bacterium PeM15, Methanosaeta and Bellilinea) in the anoxic-zone among the 3 biological zones.
Power utilization in the rural regions is assessed to be higher in the waterfront region (27 %) and forest (19 %) biological zones than in the savannah (4.3 %) regions of the nation.
The monitored results of the activated sludge sampled from six full-scale WWTPs indicated that Proteobacteria, Chloroflexi, Bacteroidetes, Actinobacteria, Verrucomicrobia, Acidobacteria and Nitrospirae were dominant phyla, and Nitrospira was the most abundant and ubiquitous genus across the three biological zones.
Methanosarcinales showed statistically significant differences in the anoxic-zone among the 3 biological zones might be caused by the high acetate concentrations (Anderson et al. 2009), which were added into the anoxic-zone as external carbon source to enhance the denitrification process.
The LEfSe analysis result indicated only13 microbial clades within an archaeal phylum of Euryarchaeota and two bacterial classes of γ-proteobacteria (with the highest LDA score) and Actinobacteria, showed statistically significant differences in the anoxic-zone among the 3 biological zones (Fig. 5).
Furthermore, the phylogeny-based UniFrac analysis (Fig. 1), clustering network analysis (Fig. 4), and LEfSe analysis (Fig. 5) demonstrated that the activated sludge samples were certainly similar between those taken from the same type of plant (i.e. the different biological zones).
A pack of pit bulls has been killing and eating wild cattle in this nature sanctuary framed by mountains and watered year-round by a river roiling through overlapping biological zones including sandy desert, boulder fields, grasslands and forests.
