Western Spruce Budworm Outbreak History
Western spruce budworm (Choristoneura occidentalis Freeman) outbreak history was reconstructed for the Sacramento Mountains of south -central New Mexico, at the southern limit of the species distribution range. Six host tree -ring width chronologies (Douglas -fir and white fir) and three non -host control chronologies (ponderosa pine) were used for this reconstruction spanning from 1800 to 1990...
متن کاملSpruce budworm antifreeze protein: changes in structure and dynamics at low temperature.
Antifreeze proteins (AFPs) prevent the growth of ice, and are used by some organisms that live in sub-zero environments for protection against freezing. All AFPs are thought to function by an adsorption inhibition process. In order to elucidate the ice-binding mechanism, the structures of several AFPs have been determined, and have been shown to consist of different folds. Recently, the first s...
متن کاملsecuritization of mortality risks in life annuities
insurers have in the past few decades faced longevity risks - the risk that annuitants survive more than expected - and therefore need a new approach to manage this new risk. in this dissertation we survey methods that hedge longevity risks. these methods use securitization to manage risk, so using modern financial and insurance pricing models, especially wang transform and actuarial concepts, ...
15 صفحه اولEntire solutions of the spruce budworm model
Here N is the spruce budworm population density, rB is the linear birth rate of the budworm and KB is the carrying capacity which is related to the density of foliage available on the trees. The P(N)-term represents predation, generally by birds. To be specific, we take the form for P(N) suggested by Ludwig et al., namely BN2 A2+N2 , where A and B are positive constants, and the dynamics of N(t...
متن کاملA Norway spruce FLOWERING LOCUS T homolog is implicated in control of growth rhythm in conifers.
Growth in perennial plants possesses an annual cycle of active growth and dormancy that is controlled by environmental factors, mainly photoperiod and temperature. In conifers and other nonangiosperm species, the molecular mechanisms behind these responses are currently unknown. In Norway spruce (Picea abies L. Karst.) seedlings, growth cessation and bud set are induced by short days and plants...
