Spruce budworm outbreaks and the incidence of vagrancy in eastern North American wood-warblers
The Tennessee (Vermivora peregrina), Cape May (Dendroica tigrina), Bay-breasted (D. castanea), and Canada (Wilsonia canadensis) warblers and the Ovenbird (Seiurus aurocapillus) appear to show positive numerical responses to outbreaks of the spruce budworm (Choristoneura fumiferana); the Magnolia (D. magnolia), Black-throated Green (D. virens), and Blackburnian (D. fusca) warblers may occur in l...
متن کاملWestern 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 کاملEntire 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 کاملComposition of the Spruce Budworm (Choristoneura fumiferana) Midgut Microbiota as Affected by Rearing Conditions
The eastern spruce budworm (Choristoneura fumiferana) is one of the most destructive forest insect pests in Canada. Little is known about its intestinal microbiota, which could play a role in digestion, immune protection, communication and/or development. The present study was designed to provide a first characterization of the effects of rearing conditions on the taxonomic diversity and struct...
متن کاملMulti-century regional western spruce budworm outbreak patterns.
D endrochronology's rich tradition has foundations rooted in the works of da Vinci and MalpighF. Although the main stem of principles was developed by A.E. Douglass (see Ref. 1), one branch of dendrochronology actually pre-dates his work. The association between narrow tree rings and damage by insects, hail and frost was recognized by Hartig in Europe at the end of the last century!. The impact...
