Small Mammal Study
||1) To study the relationship between gypsy moth and white-footed
2) To study the density and diversity of the white-footed mouse
in relation to habitat.
||Terminated in 1994.
||Bryant Mountain near Salisbury, VT. Slope was divided into
3 gradients according to the resistance to potential gypsy moth
defoliation. In 1978, the stands were 65 to 86 year old mixed
hardwoods, chiefly oak, hickory and black birch.
||3 1.44-hectare plots were established along an altitudinal
gradient. Within each plot, 49 flagged stations were established
on a 15 m grid and used as reference points for trapping small
mammals. One Sherman live trap was at each station and one pitfall
tap was at every other station to sample small mammal populations.
Plots were designed according to susceptibility to defoliation
by gypsy moths.
1) resistant plot of lower slope 210 m.
2) intermediate plot of midslope 241 m.
3) susceptible plot on ridge 341 m.
|Likelihood of Locating Study Areas:
||100% if located by the original scientist.
||None besides natural defoliation from gypsy moths.
||A 5-day census was taken twice during June and July each year.
|Variables and Sampling Frequency:
||Independent: Gypsy moth habitat.
Dependent: white-footed mouse headcount through mark and
recapture: 1979 to 1994.
||Data was entered into computer programs that have automated
||raw and summarized on DG in ASCII.
|Global Change Research Applications:
||Studies of Ecosystem Processes
