Figure 2. Release points and end points of spiders released into the open pine 
stand (solid circles indicate release point, open circles indicate where the spider was 
seen last). 
However, a significant difference did exist in the amount of vegeta- 
tion between 1-3 m high and over 3 m, with the deciduous area 
having more of this taller vegetation than the pine stand (t-test, p < 
0.01). Of the other environmental parameters measured, only insect 
length showed a significant difference between habitats (Table 3). A 
Mann-Whitney U test indicates that no significant difference existed 
in humidity or ambient temperature levels between the deciduous 
forest and the pine stand (p > 0.01). Likewise, a Mann-Whitney U 
test on the number of insects caught each day at each sticky trap 
indicates no difference between habitats (p > 0.01).
