Altitude, habitat and tropical insect diversity
1987
Wolda, H.
Sample size and species richness of a series of light-trap samples taken in a number of localities in the Republic of Panama are given. Species richness as well as sample size decreased gradually with increasing altitude over a 100–2200 m range, in contrast to data from the literature which demonstrated a maximum at intermediate elevations. It is suggested that differences in technique, especially the continuous nature of the sampling in the present case are responsible for this discrepancy. Moderate human disturbance, which leaves a relatively high tree species diversity in the area has a surprisingly little, if any, effect on insect diversity. A large perturbation of the environment does, however, decrease species richness of the insect fauna.
