“…Maintenance of crown size also has important implications for long-term survival and regrowth. Graminoid crowns are the site of both carbohydrate and nutrient storage (Adams & Wallace, 1985). Most of the dormant buds for future tiller production are located here as well.…”

SUMMARYFumigated and non-fumigated plots were planted with several species of either mycorrhizal or non-mycorrhizal grasses. These plots were either inside or outside enclosures which allowed grazing by native North American ungulates and longhorn cattle. The morphology and growth of plants as well as the level of vesicular-arbuscular mycorrhizal (VAM) development were followed over one growing season during which growing season precipitation was 50 % of the normal level. Grazing was the most important treatment effect, greatly reducing plant size and relative growth rates. Mycorrhizal colonization had no effect upon plant growth rates or size. Even in grazed plots where nutrient content and soil moisture were higher, no mycorrhizal effect on plant growth was observed. Grazing did not influence VAM colonization, although grazed plants which were growing in non-fumigated soil had significantly lower colonization levels than any other treatment.

“…However, plants sampled were two years post-fire and dormant. Thus, most nutrients were probably already translocated belowground (Adams and Wallace 1985;Seip and Bunnell 1985) and fire effects may be reduced in winter forage.…”

Scale of heterogeneity of forage production and winter foraging by elk and bison

et al. 1995

The relationship between fine-scale spatial patterns of forage abundance and the feeding patterns of large ungulates is not well known. We compared these patterns for areas grazed in winter by elk and bison in a sagebrush-grassland landscape in northern Yellowstone National Park. At a fine scale, the spatial distribution of mapped feeding stations in 30 m • 30 m sites was found to be random where there were no large patches devoid of vegetation. In areas similar to the mapped sites, the underlying spatial distribution pattern of biomass was also determined to be random. At a broad scale, forage biomass differed among communities across the northern range but forage quality did not. These results suggest that ungulates are feeding randomly within forage patches (fine scale) but may select feeding sites based upon forage abundance at broader, landscape scales. Contrary to what has been suggested in other systems, ungulates were not 'overmatching' at finer scales.

“…By mapping these known morphological, anatomical, physiological, and ecological traits on the PCA patterns, certain plant types emerged (Kindscher and Wells 1995). Prairie species group mainly by metabolism and life form (Coppedge et al 1998), so that Bromus tectorum is the only annual grass among the other perennial grasses and the only C 3 grass among the other grasses which are all C 4 grasses (Adams and Wallace 1984). In addition, B. tectorum is an exotic species that is rapidly invading many prairie areas and affecting numerous ecosystem properties (Ogle and Reiners 2003), including productivity and decomposition (Myster 2002;Ogle et al 2004).…”

How does the precipitation gradient interact with common disturbances to structure prairies?

How plant communities are structured, and the relative roles of gradients and disturbances in that structuring, has long been of interest. Here I use plots in replicate tallgrass, mixedgrass, and shortgrass prairies across Northern Oklahoma to address this issue by sampling plant percent cover three years after applying treatments realizing common prairie disturbances of burning, grazing, and soil turnover. I found (1) shortgrass plots had the least amount of aboveground biomass (AGB), with burning and soil turnover plots also having low AGB in the other two prairies, (2) tallgrass plots had the most total cover, with soil turnover plots having the least in the other two prairies, (3) tallgrass plots had the most species, with soil turnover plots having the least in the other two prairies, (4) control plots in mixedgrass had the smallest evenness and plots in shortgrass had the highest, and (5) a high degree of functional similarity in all three prairies. In addition to controlling these different aspects of population and community structure in prairies, results also show that the most severe disturbances can lead to a prairie plant composition and structure more similar to that found in the drier, most western prairie areas.
