Although the total dry matter production of an individual genet is usually not curtailed outright by browsing, height growth of browsed seedlings and suckers is then curtailed in favor of increased production of new side shoots or new ramets.
In part, this may be due to reduced short shoot production of browsed plants, as noted above.
This suggests that browsed individuals die because of increased light limitations as they become overtopped by adjacent unbrowsed individuals.
McLaren (1996) also found that shoot-browsed balsam fir is more likely to die when canopy cover was greater than 60% compared to browsed individuals grown under a more open canopy.
mariana) community with an understory of heavily browsed preferred species with increased moose population density.
Such effects on ecosystem properties are widely distributed across the landscape in characteristic patterns: patches of high density browse are heavily browsed, allowing unbrowsed conifers to invade and create coincident patches with lower available nitrogen (Pastor et al.
Danell and Huss-Danell (1985) found greater abundance of a wide variety of insect types on shoots of moderately browsed B.
Increased leaf litter nitrogen and changes in tannin chemistry of browsed Alaskan paper birch (Betula papyrifera var.
pubescens in their diet, and rebrowsed previously browsed individuals more so than did resident moose.
The research reviewed here suggests otherwise, namely that through their foraging decisions moose greatly affect the abundance and distribution of both browsed and unbrowsed plant species and ecosystem properties, and that such interactions produce patterns in the landscape (e.
