But over the course of a night, she had an evenness, even a flatness.
This strategy facilitates simulations of different community characteristics such as species evenness and species richness.
Despite these differences in vegetation and soil characteristics, there were no significant differences in species diversity (richness, evenness) or vegetation structure (woody density, frequency, basal area) as a function of distance to forest (two-way ANOVA: P>0.05), most likely due to seed inputs from surrounding early successional habitats.
The three indices that best connected the soundscape with landscape characteristics, ecological condition and bird species richness were acoustic entropy, acoustic evenness and the normalized difference soundscape index.
The different sampling protocols used here could in part explain the differences between lakes and pools, but we stress that our goal is not a comparison of these habitats per se but rather we make use of their characteristics to illustrate how the distribution of size classes in an assemblage influences evenness.
For example, as Chen et al. (2004) and Chen (2007) indicated, due to the presence of toxic pollutants (e.g., textile dyes), mixed communities would not follow characteristics under competitive exclusion principle (or Gause's law), evolving to be in cooperation for maximal species richness and evenness (Chen 2007; Chen and Chang 2007).
Even by Day 14, changes were limited, with no differences in diversity, evenness and richness.
The reason for this phenomenon is that low microphone density cannot provide enough DPD samples to measure the entropy (Pielou's evenness index), and DPD standard deviation representing the average spread of DPDs about zero is more reflective for characteristics of the DPD distribution related to the beamforming gain.
Spatial variation in functional evenness.
The repetition, the evenness, is peaceful.
