Herbaceous biomass was 1024 to 1876 kg/ha lower and herbaceous plant densities were 64 to 88% lower at the base of redberry junipers than at 6 m beyond their canopy edges. Basal cover of herbaceous plants ranged from 0.0 to 2.0% at juniper stem bases compared to a range of 5.0 to 10.0% 6 m beyond canopy edges. Species richness of grasses and forbs was reduced at juniper stem bases and at mid-canopy on some sites compared to that in the interstitial areas, whereas species richness of shrubs and succulents was greatest beneath juniper canopies. Juniper interference with herbaceous production extended at least 6 m beyond their canopy edges on a shallow, rocky Kimbrough loamy soil, but only to the edge of juniper canopies on a deep Angelo clay loam and to 1 m beyond canopy edges on a deep Tulia loam. Herbaceous biomass increased 4164% at the stem base and 74% 6 m beyond canopy edges 2 yr after mature redberry junipers were killed by soil applications of picloram (4-amino-3,5,6-trichloro-2-pyridinecarboxylic acid) on the Kimbrough soil. Herbaceous biomass responses to juniper control were limited to beneath the dead juniper canopies on the Angelo clay loam and from stem bases to 1 m beyond canopy edges on the Tulia loam. Grass densities increased 293% beneath dead juniper canopies on the Kimbrough soil and 47 and 40% at canopy edges and 1 m beyond canopy edges of dead junipers, respectively, on the Tulia loam. Basal cover of herbaceous species at the base and mid-canopy was 3.5 to 13-fold greater for dead junipers compared to live junipers 2 yr after treatment application. Species richness of grasses was enhanced by juniper control only on the Kimbrough soil. Forb species richness beneath juniper canopies was reduced following juniper control on the Kimbrough and Angelo clay loam soils, whereas there was a trend toward enhanced forb species richness beyond the canopy edges

Sensitivity of the rayleigh criterion in thermoacoustics
No full textThermoacoustic instabilities are one of the most challenging problems faced by gas turbine and rocket motor manufacturers. The key instability mechanism is described by the Rayleigh criterion. The Rayleigh criterion does not directly show how to alter a system to make it more stable. This is the objective of sensitivity analysis. Because thermoacoustic systems have many design parameters, adjoint sensitivity analysis has been proposed to obtain all the sensitivities with one extra calculation. Although adjoint sensitivity analysis can be carried out in both the time and the frequency domain, the frequency domain is more natural for a linear analysis. Perhaps surprisingly, the Rayleigh criterion has not yet been rigorously derived and comprehensively interpreted in the frequency domain. The contribution of this theoretical paper is threefold. First, the Rayleigh criterion is interpreted in the frequency domain with integral formulae for the complex eigenvalue. Second, the first variation of the Rayleigh criterion is calculated both in the time and frequency domain, both with and without Lagrange multipliers (adjoint variables). The Lagrange multipliers are physically related to the system's observables. Third, an adjoint Rayleigh criterion is proposed. The paper also points out that the conclusions of Juniper (Phys. Rev. Fluids, vol. 3, 2018, 110509) apply to the first variation of the Rayleigh criterion, not to the Rayleigh criterion itself. The mathematical relations of this paper can be used to compute sensitivities directly from measurable quantities to enable optimal design
