Forest Fragmentation as Cause of Bacterial Transmission among Nonhuman Primates, Humans, and Livestock, Uganda
|Variance component||Observed partition
||φ statistic||p value†|
|Among species||0.672||7.76||φCT = 0.078||<0.001|
|Among locations within species||0.592||6.84||φSC = 0.074||<0.001|
|Within locations||7.395||85.41||φST = 0.146||<0.001|
*Bacterial isolates were collected from 5 species in 3 locations. Locations were defined as Bugembe, Kiko 1, and Rurama fragments, and species were defined as humans, livestock (cattle and goats), black-and-white colobus, red colobus, and red-tailed guenons. Data consisted of bacterial genotypes represented as series of binary loci scored for the presence/absence of bands at each of 97 electrophoretic positions, by using the “bandmatch” procedure of the computer program BioNumerics, version 4.0 (Applied Maths, Inc., Austin, TX, USA) and optimized analytical parameters (30). Analysis of molecular variance was performed with the computer program Arlequin, version 3.0 (31).
†Probability of having a more extreme variance component and φ statistic than the observed value by chance alone; probabilities were calculated from 16,000 random permutations of the data by using Arlequin, version 3.0 (31).
