Intermittent rivers comprise a significant proportion of river networks globally and their spatial extent is predicted to increase with rising water abstraction pressures. Despite this, the ecological implications of hydrological modifications within intermittent rivers have received limited research attention. This paper examines macroinvertebrate assemblages across intermittent and perennial ...
Bermudagrass is often overseeded with a cool-season grass species in the fall to provide a green surface during cool weather. Recently, two new turfgrass species, meadow fescue and tetraploid ryegrass, have shown promise for use in overseeding situations. The objective of this study was to determine the performance of herbicides commonly used to remove (transition) perennial ryegrass from an ov...
BACKGROUND Although semi-arid and arid regions account for about 40% of terrestrial surface of the Earth and contain approximately 10% of the global soil organic carbon stock, our understanding of soil organic carbon dynamics in these regions is limited. METHODOLOGY/PRINCIPAL FINDINGS A field experiment was conducted to compare soil organic carbon dynamics between a perennial grass community ...
The USA’s federally funded Conservation Reserve Program (CRP) has largely been successful in restoring many critical ecosystem functions to millions of acres through the conversion of vulnerable croplands to diverse perennial plant communities—primarily to perennial grass and forb plantings. CRP contracts, however, on as much as 6.5 million hectares (ha) are now expiring. Aside from leaving the...
