Unbiased Report Reveals Some Of The Unanswered Questions About SRT1720
Figure 1. Plant species occurrence within and among seed bank samples (blue circle), and aboveground vegetation community samples GDC-941 from 2003�C06 (yellow circle) and 2007�C10 (green circle). Overlapping areas represent shared species; non-overlapping ... Figure 2. Above- and belowground species diversity measures from early (2003�C06) and late (2007�C10) aboveground vegetation communities, and from the soil seed bank: (A) gamma (landscape-level) diversity, (B) species richness, (C) Shannon�CWeiner ... Figure 3. Species accumulation curves for early aboveground (2003�C06), late aboveground (2007�C10) and seed bank observations as a measure of sampling effort. Sample-level or ��-diversity measured both as species richness and as Shannon diversity (H��) was lower for the seed bank than for aboveground samples; the mean seed bank species richness of 6.4 (��0.32 SE) was significantly lower than that of aboveground vegetation in both the early and late sample periods (11.5 �� 0.54 and 9.1 �� 0.38, respectively) (P check details lower than H�� in the early aboveground (1.6 �� 0.06) vegetation (P = 0.002; Fig. ?Fig.2C),2C), but was not significantly different from the late aboveground (1.4 �� 0.04) vegetation. ��-Diversity (the amount of pairwise dissimilarity for samples) was significantly greater (P = 0.003; Fig. ?Fig.2D)2D) in the seed bank (0.85 �� 0.008) than in the early and late aboveground community (0.78 �� 0.008 and 0.75 �� 0.009, respectively), which did not differ significantly (P > 0.05). Community structure and species abundance The structure of the three community groups (seed bank, early and late aboveground) was significantly different (PERMANOVA F2,168 = 20.2, P diglyceride and late aboveground compared observations were the most closely related groups within these Mantel test results (r = 0.38, P = 0.0002). Figure 4. NMDS ordination comparing the within-sample, community composition of the seed bank (black triangles), the aboveground vegetation sampled from 2003 to 2006 (grey circles) and the aboveground vegetation sampled from 2007 to 2010 (red squares). NDMS axes ... Table 2. Mantel test for association between seed bank and aboveground vegetation communities. Mantel tests were completed on Bray�CCurtis distance matrices; values of r and P are based on 5000 permutations.
