The abundance of two dominant plant
species (western wheat grass and blue grama grass) decreased with elevated CO2, which led to the increased presence of subdominant
species and hence greater
evenness in community composition.
Remarkably, the bacterial diversity of recently hatched paralarvae in captivity was similar to that of wild paralarvae and zooplankton, thus suggesting a marked effect of the diet in both the microbial community
species diversity and
evenness.
