In contrast, Schmitz [10] found that subtle differences in evenness had large consequences for ecosystem function in terrestrial old-field communities, where grazers decoupled evenness from other diversity indices.
Surprisingly, we recorded an increase in passerine community evenness from 1998 to 2002, further indicating that many more passerine species than is commonly accepted could be resilient to WNV.
Using linear mixed-effects models, we found that the Shannon diversity index decreased from 2.5 to 0.5 when the percentage of pastureland in a 2-km buffer around the sampling site increased from 0 to 80% and the annual mean temperature decreased from 16 to 4 °C, while Pielou's measure of species evenness decreased from 0.94 to 0.18 with an increase in the percentage of pastureland.
But over the course of a night, she had an evenness, even a flatness.
Pielou's index (J') of evenness varied from 0.8 to 1.0, with both transects on the flank showing lower values than other transects along the study area.
However, the opposite pattern is observed among passerines, with evenness increasing from 1998 to 2002 F1,1288 = 11.25, P = 0.001) with no difference in this increase in counties that do or do not report human WNV cases (F1,128 = 0.475, P = 0.492).

Previous theoretical work has established how changes in plant community structure (defined herein as changes in species identity, richness or evenness), either from shifts of dominance within an ecosystem, immigration or extinction, may drive ecological feedbacks on long-term time scales (Smith et al. 2009) that are relevant for global change predictions.
Finally, we intersected the gene lists established from the evenness calculation and from the human-chimpanzee microarrays and calculated a combined variation score (product of 1-evenness and score of differences).
The average number of nuclei was similar in the asexual spores of both tested heterokaryons, with a higher deviation from evenness in the spores originating from heterokaryon DE (Table 1).
To evaluate the synchronization of figs within a tree, the evenness index, modified from Smith and Bronstein (1996) was used.
