There is increasing concern over the possibility of adverse cumulative watershed effects from intensive forest management. It is impractical to address many aspects of the problem experimentally because to do so would require studying large watersheds for 100 yr or more. One such aspect is the long-term effect of forest management strategies on erosion and(More)

It is impractical to address the long-term effect of forest management strategies on erosion, sedimentation, and the resultant damage to fish habitat experimentally because to do so would require studying large watersheds for a century or more. Monte Carlo simulations were conducted on three hypothetical 10 000 ha, fifth-order forested watersheds. One(More)
The root-lesion nematodes (RLN) Pratylenchus thornei and P. neglectus are widely distributed in Australian grain producing regions and can reduce the yield of intolerant wheat cultivars by up to 65 %, costing the industry ~123 M AUD/year. Consequently, researchers in the northern, southern and western regions have independently developed procedures to(More)
Introduction: Twenty-five years after the discovery of meteoritic nanodiamonds, their origins are still unknown. Isotopic anomalies in Xe, Ba, Pd, and Te found in bulk samples of nanodiamonds can be only explained by stellar nucleosynthesis and hence indicate a presolar origin [1–4]. In contrast, C and N isotopic ratios of bulk nanodiamonds are close to(More)
The Gaia-ESO Survey is a large public spectroscopic survey that aims to derive radial velocities and fundamental parameters of about 10 5 Milky Way stars in the field and in clusters. Observations are carried out with the multi-object optical spectrograph FLAMES, using simultaneously the medium resolution (R∼20,000) GIRAFFE spectrograph and the high(More)
A study of air quality was performed using a compact, aircraft aerosol lidar designed in the Science Directorate at NASA Langley Research Center and MODIS AOD retrievals. Five flights of lidar measurements conducted in the Hampton-Norfolk-Virginia Beach region showed complex regional aerosol distributions. Comparisons with MODIS AOD at 10x10-km and 5x5-km(More)
