Ecological correlates of achene mass variation in Chrysothamnus
2003) also reported disequilibrium between plant and soil water potentials in plants from the genera Chrysothamnus
Other common vegetation species in this ecoregion include rabbitbrush Chrysothamnus
sylvestrus (Dipsacaceae) with 14 species associations, Chrysothamnus
Two males and 21 females were collected from Chrysothamnus
and Artemisia in Redmond, Deschutes County, Oregon (AMNH).
The phylogenetic method in taxonomy: The North American species of Artemisia, Chrysothamnus
, and Atriplex.
Other genera of composites that contain many cold desert subshrubs include Mausolea (close to Artemisia), which occurs in the sands of central Asia; Ajania, from the stony deserts of central Asia; Chrysothamnus
, of the deserts of North America; Haplopappus, of the deserts of North and South America; and Baccharis and Senecio, both in the deserts of South America.
The relationship between biomass and water-use efficiency (measured as carbon isotope ratio) has been explored in both well-watered and water-limited environments in a common garden study on the desert shrub Chrysothamnus
nauseosus (Donovan and Ehleringer 1994).
Sampled plants included the following forage types and genera: shrubs (Artemisia, Chrysothamnus
, Eriogonum, Krascheninnikovia, Salix, Sarcobatus); forbs (Alyssum, Atriplex, Phlox); grasses (Agropyron, Bromus, Oryzopsis, Poa); sedges-rushes (Carex); conifers (Juniperus); and lichens.
viscidiflorus) and open woodland (Juniperous osteosperma) at higher elevations.
Por ultimo, debe indicarse que Chrysothamnus
nauseosus (Palias) Britt.
Many other shrubs grow mixed in with the shadescale--the chenopods Atriplex spinescens and Sarcobatus baileyi, Chrysothamnus
viscidiflorus (Asteraceae), and Ephedra nevadensis (Ephedraceae).
