FIGURE 2. The n&r of insect families encountered in night collections oj
isoaltitudinal plotsites, plan& Forest Reserve, South &ma, Hawaili. Imu
diately notable is a general decrease of family diversity with increase in
altitude. Exever, data collected from the 4600 ft (1400 m) plotsites do
not fit vd.1 in the txend, creating a "hq" phen-n. This "hmp" is
mst pronounced in data frcnn the rain transect collections, but is present
in all transect collections. Ihe solid lines connect rrean values f m all
plotsites and derronstrate both the general trend and the deviance m the
4600 ft (1400 m) plotsites. The
blackened data points damnstrat
that the percentage of £&lies
appearing by the midpint of tk
collection period decreases witk
altitude, and is similar1
diswrdant at the 4600 ft
(1400 m) level.
