Correlations Between Insects and Birds in Tallgrass Prairie Riparian Habitats
Previous observations in riparian habitats of Kings Creek, Konza Prairie Research Natural Area, Kansas indicated that emerging aquatic insects represent a concentrated source of food for insectivorous birds, particularly the flycatcher and gleaner guilds. This hypothesis was tested by concurrent measurements of net insect emergence (total emergence minus adults returning to the stream) and dens...
متن کاملEffectivity of arbuscular mycorrhizal fungi collected from reclaimed mine soil and tallgrass prairie
We examined suitability of arbuscular mycorrhizal fungi (AMF) associated with cool-season nonnative forages on reclaimed surface-mined land in southeast Ohio for establishment of native warm-season grasses. The goal of establishing these grasses is to diversify a post-reclamation landscape that is incapable of supporting native forest species. A 16-week glasshouse study compared AMF from a 30-y...
متن کاملTallgrass Prairie: Remnants and Relicts
The tallgrass prairie once was continuous throughout the eastern Great Plains. Now, scattered remnants remain. The distribution of some of the most interesting and socially valuable remnants occur along the base of the Rocky Mountains as relicts from a past era. When the species composition of these Colorado grasslands is compared with that of the eastern tallgrass prairie by an index of simila...
متن کاملMycorrhizal fungal identity and richness determine the diversity and productivity of a tallgrass prairie system.
We investigated the effects of arbuscular mycorrhizal fungal (AMF) species richness and composition on plant community productivity and diversity, and whether AMF mediate plant species coexistence by promoting niche differentiation in phosphorus use. Our experiment manipulated AMF species richness and identity across a range of P conditions in tallgrass prairie mesocosms. We showed that increas...
متن کاملNitrogen and phosphorus dynamics of a tallgrass prairie ecosystem exposed to elevated carbon dioxide
A tallgrass prairie ecosystem was exposed to ambient and twice-ambient COz concentrations in open-top chambers and compared to unchambered ambient CO* during the entire growing season from 1989 through 1991. Dominant species were Andropogon gerardii (Cd), A. scoparius (Cd), Sorghastrum nutans (CA) and Pea pratensis (CA). Nitrogen and phosphorus concentrations in A. gerardii, P. pratensis and di...
