Effects of elevated CO2 and temperature on plant growth and herbivore defensive chemistry
Concentration of atmospheric CO2 and temperature have both been rising for the last three decades. In this century, the temperature has been predicted to rise by 2–5 °C and the CO2 concentration toExpand
Effects of reindeer browsing on tundra willow and its associated insect herbivores
Summary 1 Browsing by large mammals may strongly constrain the growth and reproduction of woody plants, and may alter the food quality and resource availability for herbivorous insects. TheExpand
Phenolic glucosides as feeding cues for willow‐feeding leaf beetles
The effects of individual phenolic glucosides and total glucoside fractions on the feeding behaviour of three willow‐feeding leaf beetles (Coleoptera: Chrysomelidae) were tested in the laboratory.Expand
The influence of windthrow area and timber characteristics on colonization of wind-felled spruces by Ips typographus (L.)
Abstract Leaving wind-felled Norway spruces in forests is one way to increase the amount of dead wood. Many forest species would benefit because of these actions but unfortunately also forest pestsExpand
EVOLUTION OF GALL MORPHOLOGY AND HOST‐PLANT RELATIONSHIPS IN WILLOW‐FEEDING SAWFLIES (HYMENOPTERA: TENTHREDINIDAE)
Abstract.— There are over 200 species of nematine sawflies that induce galls on willows (Salix spp.). Most of the species are monoor oligophagous, and they can be separated into seven or eightExpand
Terrestrial trophic dynamics in the Canadian Arctic
The Swedish Tundra Northwest Expedition of 1999 visited 17 sites throughout the Canadian Arctic. At 12 sites that were intensively sampled we estimated the standing crop of plants and the densitiesExpand
HOST-PLANT PREFERENCE OF AN INSECT HERBIVORE MEDIATED BY UV-B AND CO2 IN RELATION TO PLANT SECONDARY METABOLITES
Abstract Leaves of European silver birch (Betula pendula Roth) seedlings subjected both to ambient and increased levels of CO2 concentration (350 and 700 ppm) with no UV-B and supplementary UV-BExpand
HOST PREFERENCE AND ALLOZYME DIFFERENTIATION IN SHOOT GALLING SAWFLY, EUURA ATRA
Adaptive responses to various plant species may be a primary mechanism that leads to the formation of host races or sibling species among plant-feeding insects(Bush, 1969, 1975;Price and Willson,Expand
Tropical phenology: bi‐annual rhythms and interannual variation in an Afrotropical butterfly assemblage
Temporal variation and phenology of tropical insect communities and the role of environmental factors controlling this variation is poorly understood. A better understanding is needed, for example,Expand
Leaf litter decomposition differs among genotypes in a local Betula pendula population
Ecosystem processes, such as plant litter decomposition, are known to be partly genetically determined, but the magnitude of genetic variation within local populations is still poorly known. We usedExpand
