The species composition had changed from the initial community of the agricultural field, but was still different from a late successional target community.
When comparing the relative abundance of amoA in the initial community of the successful cultivation to the unsuccessful community (Additional file 1: Figure S6), there is 1.69 log2 fold greater representation of amoA in the unsuccessful cultivation.
To quantify community similarity progressively (i.e., year-to-baseline), we designated p as the abundance of the initial community of a route, defined as the average abundance by species for the years 1985–1987, and q as the community of the same route in each subsequent year.
Doubling the mean size of the initial communities to 20 (with standard deviation 5, rewiring (p=0.4)), we observe very similar behavior (see Fig. 4 for (text {OAS}_{text {mg}})).
Since the VSS concentrations remain relatively constant throughout cultivation, the increase in organic nitrogen and ammonium and increase in cyanobacterial 16S rRNA genes (CYAN) around day 10 14 may suggest a decay of the initial community in favor of new phototrophic growth.
Our experimental results also are consistent with epidemiological models in which adding a single non-reservoir species to an initial "community" consisting solely of the reservoir host reduces infection prevalence in the reservoir, sometimes to zero [25].
The initial community engagement goals of this SAX CAB were to i) protect participants and the Xhosa community from any research-related risks posed by the project through instrumental goals, and to ii) promote respect for Xhosa people with schizophrenia and their traditional Xhosa beliefs through intrinsic goals.
A number of factors influence successional pathways, including the composition of the initial community that can affect the success of subsequent colonists.
The survival of anecics remained constant irrespective of initial conditions, with no effect of initial community structure, food supply or initial biomass.
Because of SARS' likely place of origin, the initial "community" included Chinese persons who then kindled the chain of transmission to other communities throughout the world.
