In a common garden study on the desert shrub Chrysothamnus
nauseosus, Donovan and Ehleringer (1994) found, contrary to the results in this study, that the phenotypic correlation between water-use efficiency (measured as carbon isotope ratio) and vegetative biomass was positive in well-watered treatments and 0 in water-limited treatments, though the genetic correlation in each treatment was positive.

Another impact of periodic droughts is the small number of shrubs present in this environment, which includes Atriplex canesens (saltbush), Chrysothamnus

Historically, the Snake River Plain of southwestern Idaho was dominated largely by native shrubs (Atriplex, Artemisia, Ceratoides, Chrysothamnus
, and Purshia) interspersed with native perennial bunchgrasses (Stipa, Poa, Oryzopsis, Festuca, Sitanion, and Elymus; Yensen 1982).

Habitat was characterized by scattered shrubs including Chrysothamnus
nauseosus (rabbitbrush), Sarcobatus vermiculatus (greasewood), and Gutierrezia sarothrae (snakeweed), and an assortment of weeds on the roadside and severely deteriorated grassland of the Ninemile Valley adjacent to road 804 (Walker et al.
These differences are due to variation in the quantity and type of nutrients each shrub species provides to herbivores, and to qualitative differences in secondary compounds that presumably deter herbivory; Artemisia secondary compounds are primarily sesquiterpene lactones, whereas Chrysothamnus
produces latex (McArthur and Welch 1986).
