WebFeb 4, 2024 · Sigmoidal growth curves. Last Updated on Sat, 04 Feb 2024 Species Richness. In addition, curves of the type shown in Figure 5.8a and b may be used to suggest the pattern by which a population might increase from an initially very small size (e.g. when a species colonizes a previously unoccupied area). This is illustrated in Figure 5.8c. WebDec 7, 2024 · The unstandarized BAI sigmoidal growth model avoids detrending and standardizing employed in traditional calculation of ring-width indices (RWI) (Esper et al. 2002; Salzer et al. 2009). We employed individual tree BAI to produce mean unstandardized BAI series of all sampled trees for each year.
