Abstract:: Most higher plants have evolved with an obligatory symbiotic relationship with my corrhizal fungi. Epigeous mycorrhiza formers have their spores dispersed by air currents, but hypogeous mycorrhizal fungi are dependent upon small mammals as primary vectors of spore dissemination. Mammalian mycophagists defecate within the coniferous forest ecosystem, spreading the viable...

Abstract:: An expression for the ratio of the upwelling nadir radiance L(π, z) and the downwelling scalar irradiance Eod(Z) is derived from the following equation of radiative transfer. This expression is given by RSR(z)=[L(π, z)]/Eod(Z) = [fb(z)bb(z)]/2π[k(π, z) + c(z) – fL(z)bf(z)], where bb(z) is the backscattering coefficient, k(π, z) is...

Abstract:: Prior studies of modem scientific internationalism have been written primarily from the point of view of scientists, with little regard to the influence of the state. This study examines the state's role in international scientific relations. States sometimes encouraged scientific internationalism; in the mid-twentieth century,t hey often sought to restrict...

Abstract:: An exact expression for the remotely sensed reflectance (RSR, upwelling radiance divided by downwelling scalar irradiance) just beneath the surface of the ocean is derived from the equation of radiative transfer. It is shown that the RSR at a given depth in the ocean depends only on the inherent optical...

Creator:: Zaneveld, J. Ronald
Abstract:: An expression is derived for the rate at which the diffuse attenuation coefficient for vector irradiance approaches its asymptotic value in a homogeneous medium. The asymptotic approach rate is shown to be a function of boundary conditions at the surface and the asymptotic diffuse attenuation coefficient which is an inherent...

Abstract:: The lipid composition of an ammonium oxidizing bacterium isolated from Alaskan waters was examined at 2 different growth temperatures (5 and 25 °C). The composition was surprisingly simple with palmitic acid (C ₁₆:₀) and a monounsaturated isomer, palmitoleic acid, comprising about 90 % of the total lipids. There was a...

Abstract:: Theoretical scattering computations are performed on a phytoplankton model consisting of three concentric spheres. The outer sphere represents the wall, membrane, or frustule and is assigned a relatively high index of refraction with no absorption. The middle layer represents the chloroplasts and is assigned a relatively low index of refraction...
