Ideally studies on the population dynamics of organisms should be holistic, general, precise, and realistic (64). Much too often, however, support for research on forest pests approximates the curveExpand

Waves of Larch Budmoth Outbreaks in the European Alps
Spatially extended population models predict complex spatiotemporal patterns, such as spiral waves and spatial chaos, as a result of the reaction-diffusion dynamics that arise from trophicExpand

Genetic differentiation in Zeiraphera diniana (Lepidoptera: Tortricidae, the larch budmoth): polymorphism, host races or sibling species?
Eleven larch- and pine-feeding populations of the larch budmoth were studied in Western Europe using 24 allozyme loci. Hierarchical F-statistics between larch and pine forms (FST≍0.065) were muchExpand

Tracing the influence of larch-bud-moth insect outbreaks and weather conditions on larch tree-ring growth in Engadine (Switzerland)
Tree-ring analysis of insect-defoliated trees has so far been used for detecting past insect outbreaks only. We hypothesize that the impact of the larch-bud-moth (LBM) Zeiraphera diniana outbreaks onExpand

The Larch Budmoth in the Alps
During the late 1940s, immediately after World War II, the lush green forests of the Engadine Valley, high in the Swiss Alps, turned an ugly red-brown in the midst of the tourist season. This was dueExpand

Why the larch bud-moth cycle collapsed in the subalpine larch-cembran pine forests in the year 1990 for the first time since 1850
The larch bud-moth cycle has been observed in the sub-alpine larch-cembran pine forests 16 times since 1850. Infestation is easily recognized by the characteristic red-brown discoloration of theExpand

The potential for using Larix decidua ring widths in reconstructions of larch budmoth (Zeiraphera diniana) outbreak history: dendrochronological estimates compared with insect surveys
Abstract. In the Alps, larch (Larix decidua Mill.) forests show periodic discolouration due to larch budmoth (LBM) outbreaks (Zeiraphera diniana Guénée, Lepidoptera: Tortricidae). Tree defoliationExpand

A contribution to the explanation of the larch bud moth cycle, the polymorphic fitness hypothesis
Studies of fluctuating insect populations generally discuss the regulating processes at high insect numbers, but very rarely why a cycling population at low densities switches immediately from theExpand

Abstract The likelihood of sympatric speciation is enhanced when assortative mating is a by‐product of adaptation to different habitats. Pleiotropy of this kind is recognized as important inExpand
