Reconnecting to the Biosphere
It is suggested that the Millennium Development Goals need to be reframed in such a planetary stewardship context combined with a call for a new social contract on global sustainability.
Sexual Dimorphism and Biotic Interactions
In the last decade, an increasing number of studies have suggested that males and females of dioecious plants may be differentially affected by competition, herbivory, and parasitism. In dioecious
Feeding by insects and hares on birches earlier affected by moose browsing
Les arbres broutes anterieurement par Alces alces sont generalement plus infestes par les insectes that les non-broutes, notamment par les lievres.
Effects of simulated herbivory and intraspecific competition on the compensatory ability of birches
The results indicate that there is little value in asking whether herbivory has a positive or negative effect on plant growth, and suggest that overcompensation should not generally be considered as an adaptive response that has evolved as a consequence of natural selection due to Herbivory, but rather as an indirect consequence of selection for competitive ability.
Diet choices made by free-ranging moose in northern Sweden in relation to plant distribution, chemistry, and morphology
The diets of 41 moose in northern coastal Sweden contained 75% Scots pine (Pinus sylvestris) and willow and the remaining proportion equally divided among five deciduous browse species and common juniper (Juniperus communis).
The Role of Moose as a Disturbance Factor in Managed Boreal Forests
We review the interactions between moose (Alces alces) and native tree species in Fennoscandia. The Fennoscandian boreal forests have been intensively managed for wood production over decades. Moose
Predicting bite size selection of mammalian herbivores: a test of a general model of diet optimization
A model that predicts a quantitative solution to 'optimal bite size' based on constraints in harvesting and digesting foods and suggests possible ways to enhance the model and how it can be used to assess forage availability, potential diet quality, and the vulnerability of trees to herbivory.
Disturbance by large herbivores in boreal forests with special reference to moose.
Moose and reindeer occur in large populations in the Fennoscandian boreal forests, and also roe deer occurs in dense populations in Sweden and Norway. These large herbivores affect the structure and
Herbivore avoidance by association: vole and hare utilization of woody plants
The probability that an individual plant will be attacked by a herbivore depends not only on the characteristics of the individual plant, but also on the quality and abundance of its neighbours.
Interactions between Browsing Moose and Two Species of Birch in Sweden
Responses ofjuvenile birches to moose browsing and the responses of moose to browsed trees found no support for the occurrence of induced defense in juvenile trees; those that had been browsed during the previous winter were more palatable than previously unbrowsed trees.
