| plant species diversity and composition of wetlands within an upland forest. | though often overlooked, small wetlands in an upland matrix can support diverse plant communities that increase both local and regional species richness. here we characterize the full range of wetland vegetation within an upland forest landscape and compare the diversity and composition of different wetland plant communities. in an old-growth forest reserve in southern quebec, canada, we sampled wet habitats including lakeshores, permanent and seasonal ponds, swamps, glades, and streamsides. we ... | 2008 | 21632326 |
| infection by the systemic fungus epichloë glyceriae alters clonal growth of its grass host, glyceria striata. | parasites and pathogens are hypothesized to change host growth, reproduction and/or behaviour to increase their own transmission. however, studies which clearly demonstrate that parasites or pathogens are directly responsible for changes in hosts are lacking. we previously found that infection by the systemic fungus epichloë glyceriae was associated with greater clonal growth by its host, glyceria striata. whether greater clonal growth resulted directly from pathogen infection or indirectly from ... | 2003 | 12908979 |
| potential for using native plant species in stormwater wetlands. | spartina pectinata (prairie cordgrass) was grown under five hydroperiods (wet-dry cycles) to determine its potential for use in stormwater wetlands, particularly as an alternative to the highly invasive phalaris arundinacea (an exotic grass). rhizomes planted in outdoor microcosms grew vigorously in all treatments, namely, weekly flooding in early summer, weekly flooding in late summer, flooding every three weeks throughout the summer, weekly flooding throughout the summer, and no flooding. neit ... | 2002 | 11830768 |
| photosynthesis in grass species differing in carbon dioxide fixation pathways: ii. a search for species with intermediate gas exchange and anatomical characteristics. | thirty-three grass species were examined in two experiments in an attempt to locate plants with photosynthetic responses to o(2), co(2) compensation concentrations, and leaf anatomy intermediate to those of c(3) and c(4) species. species examined included seven from the laxa group in the panicum genus, one of which, p. milioides nees ex trin., has been reported earlier to have intermediate characteristics. the species with o(2)-sensitive photosynthesis typical of c(3) plants showed more than 37% ... | 1979 | 16660944 |
