    Abstract. Plant functional traits provide one tool for predicting the effects of grazing on different ecosystems. To test this approach, we compared plant traits and grazing response across analogous climatic gradients in sagebrush steppe, USA (SGBR), known to have a short evolutionary history of grazing, and Patagonian steppe, Argentina (PAT), where generalist herbivores exerted stronger.

    Further, three species, P. spicata, A. thurberianum and P. secunda, appear to be especially important determinants of such resistance. P. spicata and A. thurberianum are dominant deep‐rooted bunchgrasses with most active growth in later spring, whereas P. secunda is a shallow‐rooted bunchgrass that is active in late winter and early by: The steppe species of gastrointestinal nematodes of small ruminants, with a focus on Marshallagia: climate as a key determinant Les espèces de nématodes gastro-intestinaux des petits ruminants de la steppe, avec une attention particulière pour Marshallagia: le climat comme déterminant essentielCited by:

George Van Dyne's grasp of ecosystem science led him to produce and edit a book entitled, The Ecosystem Concept in Natural Resource Management.   Ecophysiological traits of Prosopis juliflora (Sw.)

Brenan, were studied to understand the invasive species’ success in caatinga, a seasonally dry tropical forest ecosystem of Cited by:

Ecology of the Shortgrass Steppe: A Long-Term Perspective summarizes and synthesizes more than sixty years of research that has been conducted throughout the shortgrass region in North America.

The shortgrass steppe was an important focus of the International Biological Program's Grassland Biome project, which ran from the late s until the mids. Several aspects of photosynthetic adaptation to temperature were examined in four graminoid species from the Colorado shortgrass steppe.

The experimental species were chosen to provide examples of a variety of in situ seasonal phenology patterns. The cool season grass, Agropyron smithii (C3), exhibited higher photosynthesis rates when grown in a cool temperature regime Cited by: Ecology of the Shortgrass Steppe: A Long-Term Perspective summarizes and synthesizes more than sixty years of research that has been conducted throughout the shortgrass region in North America.

Elevated CO2 in the shortgrass steppe Morgan, Jack A. 3 1 INTRODUCTION 2 Atmospheric [CO2] has been rising steadily from approximately µL L 3 -1 at the start of the industrial 4 revolution to over µL L-1 today, and is predicted to exceed µL L by the end of the century (IPCC, ).

5 Most plant species exhibit increased production when [CO2] is increased above present ambient. There is a lack of information on how best to restore areas of the shortgrass steppe region of the United States that have been degraded by disturbances. In a previous set of short-term studies we explored restoration approaches based upon novel seeding approaches.

In these studies we used new species combinations and new seeding rates based on emerging ecological principles. The next ecological book written on the shortgrass steppe will need to focus on important human-landscape interactions as the urban conflagrations of Cheyenne, Fort Collins, Greeley, Denver, Colorado Springs, and Pueblo continue their spread eastward.

In the meantime, this book is a “must-have” operating guide for understanding. We examined the importance of plant species and plant cover (i.e., plant covered microsites vs. bare soil) on nutrient cycling in shortgrass steppe of northeastern Colorado. We tested the effects of both plant species and cover on soils in an area of undisturbed shortgrass steppe and an area that had undergone nitrogen and water additions from Cited by: Ecology of the Shortgrass Steppe: A Long-Term Perspective summarizes and synthesizes more than sixty years of research that has been conducted throughout the shortgrass region in North America.

Develop some hypotheses that explain why the vegetation in the shortgrass steppe is so very different than in the Rocky Mountains and foothills, which are fewer than miles to the west.
