In crested wheatgrass, the species Agropyron cristatum includes populations that are diploid and tetraploid, either naturally or artificially induced. The species Agropyron desertorum is tetraploid and there are culitvars that are hybrids between A. cristatum and A. desertorum. The goal of this study was to compare the morphology (height, crown width, tiller density, tiller weight and tiller angle) of populations from the two species and hybrids, including S9240, a recently developed colchicine induced tetraploid A. cristatum. Data were collected in 1999 and 2000 from several different sward-seeded and spaced-planted trials. The four tetraploid crested wheatgrasses (A. cristatum “Kirk” and “S9240”, A. desertorum “Nordan”, and A. desertorum × A. cristatum “CD-II”) were significantly (P < 0.05) taller, narrower in row width, and produced fewer, heavier tillers than the diploid A. cristatum “Parkway”. Among the tetraploid populations, S9240 was significantly (P < 0.05) taller and produced fewer tillers. S9240 also produced significantly (P < 0.05) heavier tillers than CD-II and Nordan, and also than Kirk, one year of two. Row widths were variable among populations, but S9240 generally produced a narrower crown than other populations. Key words: Crested wheatgrass, polyploidy, plant height, crown diameter, tiller characteristics

Productivity and durability of 29- to 38-year-old stands of crested wheatgrass, Agropyron cristatum Gaertn., were assessed. Crested wheatgrass consistently outyielded the grass and sedge component of Mixed Prairie native range vegetation by a ratio that ranged from 12.42 to 1.08. Analysis of soils showed that exhaustion of N was not a factor in persistence of stands. The data indicated that, in the study area, seeded stands of crested wheatgrass became a permanent part of the vegetation and that yield was dependent mainly on current rainfall.

Habitat alteration by exotic plant species can have profound effects on vertebrates, but its effects on invertebrates are less well-known. Crested wheatgrass (Agropyron cristatum (L.) Gaertn.) is a perennial grass that has been planted on >106ha of the Great Plains. We tested the hypothesis that invertebrate communities (especially ants) differed between native grasslands and A. cristatum stands, using pitfall traps in Saskatchewan and Montana. Ant species composition differed significantly between native grasslands and A. cristatum stands, but there were no differences in total ant abundance, the abundance of functional groups, or species richness. Ant species richness was significantly greater in Montana than Saskatchewan. In Saskatchewan, bare ground was positively related to total ant abundance and the abundance of “cold-climate specialist” and “opportunist” functional groups of ants. In Montana, the cover of forbs was positively related to total ant abundance. The abundances of individual ant species were not predicted by any vegetation characteristics, except for Formica obscuripes Forel, 1886, which increased significantly with litter. The total abundance of other invertebrates was greater in native grasslands than in A. cristatum stands, although not significantly so. Within each vegetation type, variation in ant communities may depend either directly on the effects of vegetation species composition, or indirectly via the effect of vegetation on other factors such as temperature. The results suggest that ant community composition was influenced more by variation within grasslands and between locations than by differences between native and exotic grasslands.
