Abstract
Recent studies have shown that genetically based traits of plants can structure
associated arthropod and microbial communities, but whether the effects are consistent and
repeatable across years is unknown. If communities are both heritable (i.e., related individuals
tend to support similar communities) and repeatable (i.e., the same patterns observed over
multiple years), then plant genetics may also affect community properties previously thought
to be emergent, such as ‘‘stability.’’ Using replicated clones of narrowleaf cottonwood
(Populus angustifolia) and examining an arthropod community of 103 species, we found that
(1) individual tree genotypes supported significantly different arthropod communities, which
exhibited broad-sense heritability; (2) these findings were highly repeatable over three
consecutive years (repeatability¼0.91) indicating that community responses to individual tree
genotypes are consistent from year to year; (3) differences among tree genotypes in community
stability (i.e., changes in community composition over multiple years) exhibited broad-sense
heritability (H2C
¼0.32). In combination, these findings suggest that an emergent property such
as stability can be genetically based and thus subject to natural selection.
