Long-term responses of ecosystem components to stand thinning in young lodgepole pine forest

Interactions between timber harvesting and swamp wallabies (Wallabia bicolor): Space use, density and browsing impact

“…Similar increases in the density of other mammalian herbivores within 12 months of harvesting have been found in both native forests (St-Louis et al, 2000) and plantations (le Mar and McArthur, 2005), and elevated moose (Alces alces) and mule deer (Odocoileus hemionus) density were positively correlated with increased forage availability resulting from precommercial thinning (Sullivan et al, 2007). Although it was not an objective of this study to quantify the reasons for the observed density effect, qualitative observations suggest that the presence of shelter was important.…”

The role of the wood mouse in Quercus serrata acorn dispersal in abandoned cut-over land

“…Acorn crops and wood mouse abundance are commonly characterized by extreme annual variation at irregular intervals (Miguchi, 1996;Healy et al, 1999;Sone et al, 2002;Constantine et al, 2004;Sullivan et al, 2005). For example, acorn production by Fagus crenata in Japan fluctuates from zero in a poor seed year to about 400 acorns/m 2 in a good mast year (Yasaka et al, 2003).…”

The influence of forest cover on mule deer habitat selection, diet, and nutrition during winter in a deep-snow ecosystem

“…In addition, browse under forest crowns is less likely to be buried by snow (Harestad, 1985), and some conifers such as Douglas-fir (Pseudotsuga menziesii) and western redcedar (Thuja plicata) are fed on by ungulates as are the arboreal lichens attached to their boles and canopy (Dawson et al, 1990;Pauley et al, 1993;Armleder et al, 1994;D'Eon, 2001). Overall, however, there is far less browse under canopies than open habitats (Jameson, 1967;Thomas, 1979;Peek et al, 2001;Sullivan et al, 2007). Ungulates, therefore, must weight the varied benefits of a forest canopy against the costs of an overall lower abundance of browse under dense canopies (Jameson, 1967;Thomas, 1979;Peek et al, 2001;Sullivan et al, 2006Sullivan et al, , 2007.…”
