Waterlogging tolerant tree species exert a critical role in forest preservation and the associated water conservation flood prone areas. Clarifying patterns drivers of uptake by waterlogging trees is crucial for management flood-prone areas, especially scenario precipitation changes estuary delta. Here, we uploaded values δD δ18O obtained from soil xylem waters to Bayesian mixed model (MixSIAR)...

A controlled study using a sand-tank system was conducted to evaluate 10 forage species (bermudagrass, ‘Salado’ and ‘SW 9720’ alfalfa, ‘Duncan’ and ‘Polo’ Paspalum, ‘big’ and ‘narrow leaf’ trefoil, kikuyugrass, Jose tall wheatgrass, and alkali sacaton). Forages were irrigated with sodium-sulfate dominated synthetic drainage waters with an electrical conductivity of either 15 or 25 dS/m. Forage ...

Assembly Bill 1982 provides funding to implement mosquito best management practices (BMPs) at wildlife areas managed by the California Department of Fish and Game. The first year of the program is 2005-2006. A protocol for sampling immature mosquitoes (larvae and pupae) is outlined in this document. The document is intended to focus on three wildlife areas, but is likely applicable to other wil...

Diazotrophs provide the only biological source of fixed atmospheric nitrogen in the biosphere. Although they are the key player for plant-available nitrogen, less is known about their diversity and potential importance in arid ecosystems. We investigated the nitrogenase gene diversity in native and agricultural desert soil as well as within root-associated microbiota of medicinal plants grown i...

Turfgrass selections including 21 paspalums (Paspalum vaginatum Swartz) and 12 zoysiagrasses (Zoysia sp.) were compared with susceptible ‘KY31’ tall fescue (Festuca arundinacea Schreb.) and more resistant common bermudagrass (Cynodon dactylon Pers.) and common centipedegrass [Eremochloa ophiuroides (Munro.) Hack] for potential resistance to fall armyworm [Spodoptera frugiperda (J.E. Smith)], an...

In the present work the presence of Paspalum notatum Flüggé (Poaceae) in Italy was reported for the fi rst time. It is a neophyte native to America, known for applications in phytoremediation. Its typifi cation, ecology and invasiveness status are also presented.
