Isotope hydrology of a tropical coffee agroforestry watershed: Seasonal and event‐based analyses

Impacts of coffee agroforestry management on tropical bee communities

Please cite this article in press as: Jha, S., Vander doi:10.1016/j.biocon.2010.03.017 Though it is undoubted that tropical bees are influenced by habitat composition, few studies have investigated the relative importance of both local and landscape-level habitat parameters in supporting large and diverse bee communities. The conservation of native bee communities within agroforestry landscapes...

Seasonal Isotope Hydrology of Three Appalachian Forest Catchments

Seasonal oxygen-18 variations in precipitation, throughfall, soil water, spring ̄ow and stream base ̄ow were analysed to compare the hydrology of two forested basins in West Virginia (WV) (34 and 39 ha) and one in Pennsylvania (PA) (1134 ha). Precipitation and throughfall were measured with funnel/bottle samplers, soil water with ceramic-cup suction lysimeters and spring ̄ow/base ̄ows by grab and...

Agroforestry practices, runoff, and nutrient loss: a paired watershed comparison.

A paired watershed study consisting of agroforestry (trees plus grass buffer strips), contour strips (grass buffer strips), and control treatments with a corn (Zea mays L.)-soybean [Glycine max (L.) Merr.] rotation was used to examine treatment effects on runoff, sediment, and nutrient losses. During the (1991-1997) calibration and subsequent three-year treatment periods, runoff was measured in...

A review of research dealing with isotope hydrology in Iran and the first Iranian meteoric water line

For more than half a century isotopes have been employed as a powerful tool in studying various aspects of water resources in a largenumber of countries. However, in developing countries like Iran the application of such techniques is in its infancy. The first research inIran was carried out in 1975 to identify the source of saline groundwaters in south Iran, and the first national conference o...
