Figure 1.
Bacterial growth in pure cultures.
Time-course changes in abundance of A. agilis, A. hydrophila, Brevundimonas sp., Flavobacterium sp., and L. planktonicus (invader) grown in pure cultures either in low- (LCC) or in high-carbon concentration (HCC) treatments. Note different scales of y-axes in different panels. Values are means of triplicates, error bars = SD.
Figure 2.
Temporal changes in abundances of total bacteria grown in control community or in the community invaded by L. planktonicus either in low- (LCC) or in high-carbon concentration (HCC) treatments. Note different scales of y-axes in different panels. Values are means of triplicates, error bars = SD.
Figure 3.
Bacterial growth in communities.
Temporal changes in abundances of A. agilis, A. hydrophila, Brevundimonas sp., Flavobacterium sp., grown in control community (A) or in the community invaded by L. planktonicus (B) either in low- (LCC) or in high-carbon concentration (HCC) treatments. Note different scales of y-axes in different panels. Values are means of triplicates, error bars = SD.
Figure 4.
Numerical ratio of abundance of A. agilis, A. hydrophila, Brevundimonas sp. and Flavobacterium sp. achieved in invaded community compared to that in control community either in low- (LCC) or in high-carbon concentration (HCC) treatments. Asterisks above or below bars indicate significant differences in abundance of bacterial strains in the invaded community from that in the control community (two-way repeated measures ANOVA). * P<0.05, *** P<0.001.
Figure 5.
Shannon-Wiener (H’) diversity index in control and invaded communities. For consistency, H’ in invaded communities was determined without regards of the relative contribution of L. planktonicus. Calculations were made both, for low- (LCC) and high-carbon concentration (HCC) treatments. Values are means of triplicates, error bars = SD. Asterisks above plots indicate significant differences in diversity index in the invaded community from that in the control community (two-way repeated measures ANOVA). * P<0.05, ** P<0.01, *** P<0.001.
