Pleistocene graminoid-dominated ecosystems in the Arctic
Quaternary Science Reviews, 2011Abstract We review evidence obtained from analyses of multiple proxies (floristics, mammal remains, paleoinsects, pollen, macrofossils, plant cuticles, phytoliths, stable isotopes, and modeling) that elucidate the composition and character of the graminoid-dominated ecosystems of the Pleistocene Arctic.

Shoot growth and morphometric analyses of Serengeti graminoids
African Journal of Ecology, 1985SummaryNine species from the Serengeti National Park, Tanzania, were studied to provide morphometric and growth rate parameters for a simulation model of their growth (Coughenour, McNaughton & Wallace, 1984). Short grasses had a much greater capability than taller species for packing a large number of shoots with a high proportion of lamina on a ...

Leaf mass loss in wetland graminoids during senescence
Oikos, 2005Mass loss of senescing leaves is an important part of plant biomass turnover and has consequences for assessment of ecosystem productivity, ecosystem nutrient use efficiency, and plant nutrient resorption efficiency. Data, however, on mass loss are scarce, and often based on leaf area as the reference base.

Effects of daylength and temperature on root elongation in tundra graminoids
Oecologia, 1977Effects of soil temperature and daylength on root elongation of Carex aquatilis, Dupontia fischeri, and Eriophorum angustifolium were studied under both field and phytotron conditions. Late season decrease in root elongation rate and cessation of root elongation in Dupontia and Eriophorum are shown to be controlled by decreasing daylength.

Spatial and temporal variation in carbon isotope discrimination in prairie graminoids
Oecologia, 1994We present the results of a 5-year examination of variation in the stable carbon isotope composition (δ) of three C3 graminoid species from a Sandhills prairie: Agropyron smithii, Carex heliophila and Stipa comata. Although consistent species-specific patterns for mean δ were seen, there was also significant and substantial among-year and within-season

Developing graminoid cuticle analysis for application to Beringian palaeoecology
Review of Palaeobotany and Palynology, 2010Abstract Much of Beringia was composed of graminoid (grass and sedge) dominated habitats during the Late-Pleistocene, yet the account of the actual gramioids that were present is relatively vague. The spatial and temporal variabilities of palaeoclimate, mega-fauna, archaeology, and vegetation interactions could be significantly enhanced with accounts

Simulation study of east-African perennial graminoid responses to defoliation
Ecological Modelling, 1984Abstract The responses of East African grasses to defoliation at specific heights and frequencies were simulated mathematically over a single optimal growing season. The simulation model used morphological and physiological features of graminoid growth that are known to affect responses to defoliation.

Graminoid community composition and structure within four everglades management areas
Wetlands, 1990Estimates of species density, percentage vegetative cover, biomass, and sawgrass (Cladium jamaicense) height were made in Tall Sawgrass, Medium Sawgrass, and Wet Prairie communities in the SE portion of Water Conservation Area 3A (3A), the SW portion of Water Conservation Area 3B (3B), the NW portion of Northeast Shark Slough (NSS), and the NE portion ...

Can graminoids used for mine tailings revegetation improve substrate structure?
Botany, 2016The seeding of agronomic graminoid species that are tolerant to the compacted and low aeration conditions associated with mine tailings allows for rapid cover of mine waste, which in turn controls erosion. These graminoids can be used as primer-species on mine tailings to improve the rooting of other plant species, which may not tolerate soil ...
