The spatio-temporal dynamics of populations of two 9-10 year cyclic-outbreaking geometrids, Operophtera brumata and Epirrita autumnata in mountain birch forests in northern Fennoscandia, have been studied since the 1970´s by a Swedish-Norwegian rese

1.We show that the population ecology of the 9- to 10-year cyclic, broadleaf-defoliating winter moth (Operophtera brumata) and other early-season geometrids cannot be fully understood on a local scale unless population behaviour is known on a Europea

Seven cases of presumed epimeletic behaviour of adult Common Swifts toward flying young were recorded. The behaviour varied from adults escorting the young, over episodes when part of the colony swirled around the newcomer, to instances when an adult

1. In recent studies, it has been argued that sunspot activity forces the Epirrita autumnata 9-10-year outbreak periodicity in the mountain birch forest of Fennoscandia. For the following reasons, we challenge this conclusion. 2. With a 10-year outbr

Important findings, e.g. in ecology, should be questioned and debated. Our findings that defoliating looper outbreaks travel as waves across Europe and the response here to such a questioning could be a start of a debate (photo: winter moth carterpil

Variation in in situ growth performance of the mountain birch as indicated by the widths of annual rings was analysed and related mainly to temperature and herbivory using ring width series from five heath forest sites in the Lake Tornetrask area, no

Mountain birch (Betula pubescens ssp. czerepanovii) forest in the Abisko valley of northern Sweden was completely defoliated by Epirrita autumnata caterpillars during an outbreak in 1954–1955. The defoliation resulted in an 80–90% mortality of th

1. In the early 1990s, birch Betula pubescens L. forests in north-western Norway were damaged by the bud- and shoot-mining larvae of Argyresthia retinella not previously known for outbreaks. In 1993–96, the outbreak was mapped and changes in attack

1 Abundance of leaf-mining larvae of the outbreak species Eriocrania spp. was monitored in northern Sweden in 1955–67 and 1984–92 in a mountain birch forest rejuvenated by an Epirrita autumnata outbreak in 1954–55. 2 Eriocrania mine density flu

The supercooling point (SCP) of individual Epirrita autumnata eggs (approx. 60 eggs batch−1) was tested each month from September (eggs newly laid) to April under laboratory conditions simulating winter temperatures in the field (from + 4 to −30
