STUDY SITE The ahupua'a of Manuka, Kaulanamauna, and Kapu'a lie upon the southwestern flank of the Mauna Loa shield volcano in the South Kona district of the island of Hawai'i. These triangular sections of land extend downslope from their common apex at Pu'u Ohohia (1690 m) along the Southwest Rift Zone of Mauna Loa, fan- ning outward to include a 12 km expanse of shoreline at their bases (USGS topographic quadrangles 1967). Transects and sample stations METHODS Field study was conducted from June 15 to July 31, 1977. The survey of insect fauna was one aspect of a holistic ecosystem baseline survey of the Manuka area conducted under the auspices of the National Science Foundation. Twelve sampling stations were established along two parallel transect access lines in altitudinal increments of 290 m running from Pu'u Ohohia downslope. The arrangement of sampling stations is illustrated in Figure 1. This placement established two replicate stations at the 1440, 1150, and 875 m elevations, and one replicate at the 585 m elevation. The study area boundaries precluded establishing replicates at the 1690 m level, while commercial agriculture at one of the 585 m plotsites made consid- erations of sampling at that location moot. Whenever possible, the entomology sampling station plotsites coincided with that of the Manuka Research Project vegetation ecology survey sites, in order to have available detail-ed vegetation data. Sampling techniques In this study, only the night fauna was considered. Night collection commenced at 7:00 PM and ran continuously to 10:OO PM. Each night collection utilized a simple sheet light trap. A Coleman-type lantern provided attractive illumination. A1 1 insects that came to rest upon the sheet were collected during the 3-hour period, and kept for identification. Large insects were collected with sweep nets, while smaller insects were aspirated into vials. Data analysis The number of families encountered at each plot were cumu- lated, and mean values for isoaltitudinal plots were computed. The trends in the diversity of insect communities at the family
level were analysed against altitude distributions of the sample station plotsites via correlation coefficients generated by: = S x ~ where 2xy (covariance). = 1 (Cxiyi - 1 XxiCyi) SxS y n-l n and 2, = hi2 - (CX?) '/n j .-I - sy = jiyi2 - (~yi)~/n n - 1 where 2, and sy are standard deviations, x and y being values of two discrete and changing factors: alfitude and the number of insect families encountered. RESULTS There was a general linear increase in the number of families collected with decreasing altitude (Table 1). Correlation coefficients calculated using the mean number collected at isoaltitudinal plots substantiated of families this linear relationship (r n = 5). - = -0.72, - With decreasing altitude, greater numbers of families appeared during the first half of the collection periods. At the 1690 m station, 50% of families encountered were collected by the midpoint of the collection period. At 1150 m, this figure had increased to 70%. while at 875 m it was 79% and at 585 m, the insects collected by the first half of the collecting period amounted to 84% of the total yield. The rise in this temporal packing correlated with altitude (r - = -0.74, - n = 12). An interesting exception to the linear relationship of both family diversity and temporal packing trends ocurred at the 1440 m elevation, where both diversity and packing exceeded figures characteristic of the 1150 m plots, and were only slightly lower than values at the 875 m level. This "hump" is easily seen in Figure 2. If the data from the 1440 m plots are deleted, and correlation coefficients are again calculated, the linear fit against altitude is far more precise (family diversity/altitude - r = -0.82, - n = 9; temporal packing/altitude - r = -0.91, - n = 9). The distribution of entomology sites, vegetation ecology relevi stations, habitat descriptions, and climatic observations along the altitudinal gradient are presented in Figure 3. The number of vascular plant species and insect families encountered at identical sites are compared in Figure 4. The data is utilized in the discussion to assess vegetational correlations and to incorporate several situations to interpret both general trends and the "hump" phenomenon.
