Consumers desire low-input turfgrasses that have tolerance to both shade and drought stresses. Several sedges ( Carex sp.) nimblewill Muhlenbergia schreberi ) are native plants prevalent in dry woodland ecosystems Oklahoma, USA, may potential as alternatives conventional species shaded turfgrass systems. To evaluate selected for this purpose, a multilocation field trial was conducted Stillwater...

Water-level fluctuations are critical in maintaining diversity of plant communities Great Lakes wetlands. Sedge-grass meadows especially sensitive to such fluctuations. We conducted vegetation sampling a sedge-grass dominated Lake Michigan drowned river mouth wetland 1995, 2002, and 2010 following high lake levels 1986 1997. also photointerpretation studies 16 years dating back 1965 include res...

Abstract. Arctic warming and permafrost degradation are modifying northern ecosystems through changes in microtopography, soil water dynamics, nutrient availability, vegetation succession. Upon degradation, the release of deep stores nutrients, such as nitrogen phosphorus, from newly thawed stimulates production. More specifically, wetter lowlands show an increase sedges (as part graminoids), w...

To understand long-term changes in Chicago region wetlands, in 2002 we investigated the status of 31 high quality grassor sedge-dominated wetland plant communities that were originally sampled in 1976. Our objectives were to quantify vegetation changes over time by resampling transects and then correlating changes with site fire histories, as well as other factors linked with compositional and ...

Soil samples from 15 eutrophic, 26 herb-rich, 15 tall-sedge, and 11 low-sedge drained peatland sites were analysed for easily soluble and aluminum, iron, and calcium bound phosphorus (P) using the Chang and Jackson sequential fractionation method. Compared to earlier investigations, where only total and easily soluble P contents (e.g. NH4OAc or dilute H2SO4 extractable P) in peat have been anal...

Since it was established that the early hominins of Cradle Humankind in South Africa ate 13C-enriched foods may have included sedges with C4 photosynthetic pathways, much work has focused on reconstruction hominin dietary ecologies both southern and eastern Africa. Through years emphasis placed Cyperus papyrus as a possible source, even inspiring an ‘aquatic diet’...
