Spectral Reflectance From A Broccoli Crop With Vegetation Or Soilias Background: Influence On Immigration By Brevicoryne Brassicae And Myzus Persicae, Michael J. Costello
Spectral Reflectance From A Broccoli Crop With Vegetation Or Soilias Background: Influence On Immigration By Brevicoryne Brassicae And Myzus Persicae, Michael J. Costello
Horticulture and Crop Science
Light reflectance in five wavebands of the spectrum was measured from broccoli (Brassicae oleracea var.botrytis [L].) interplanted with leguminous cover crops (cover crop background) or broccoli grown as monoculture (bare soil background), and fertilized with compost or synthetic fertilizer. Alate Brevicoryne brassicae (L.) and Myzus persicae (Sulzer) (Homoptera: Aphididae) were monitored in yellow pan water traps and on broccoli leaves. Reflectance intensity was higher with a background of bare soil at all wavebands except blue (400–455 nm) in the early-season. Intensity decreased as broccoli canopy cover increased at all wavebands except blue and green (515–550 nm), declining-most dramatically in …

Reasserting A Prehistoric Tragedy Of The Commons: Reply To Lyman, Terry L. Jones, William R. Hilderbrandt
Reasserting A Prehistoric Tragedy Of The Commons: Reply To Lyman, Terry L. Jones, William R. Hilderbrandt
Social Sciences
R. Lee Lyman has challenged our assertion that prehistoric hunting of marine mammals along the west coast of North America approximated a prehistoric tragedy of the commons in which highly ranked migratory sea lions and fur seals were reduced by overexploitation, necessitating pursuit of smaller, more elusive harbor seals and sea otters late in time. In response, we review alternative theoretical perspectives, rebut Lyman's characterization of marine mammal reproductive behaviors, reanalyze seal and sea lion NISP data from the California and Oregon coasts, and reinterpret three regional prehistories. Because migratory pinnipeds need to breed on land, are vulnerable to terrestrial …
