Grazing by captive Barnacle geese affects graminoid growth and productivity on Svalbard

open access: yesGrazing by captive Barnacle geese affects graminoid growth and productivity on Svalbard
P(論文) Migratory geese breed in Svalbard in summer and return to Western Europe for the winter, feeding on wetlands and agricultural fields. Recent changes in climate, land use and the implementation of protective measures dramatically improved the birds' ability to survive the winter, increasing population sizes and thus the potential grazing impact on

Pleistocene graminoid-dominated ecosystems in the Arctic

Quaternary Science Reviews, 2011
Abstract 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, 1985
SummaryNine 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, 2005
Mass 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, 1977
Effects 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, 1994
We 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
