Numbers and Biomass of Selected Insect Groups on Burned and Unburned Sand Prairie

Student Database

Author: Anderson, Roger C.; Leahy, Theresa; Dhillion, Shivcharn S. Description: Abundance and biomass of selected insect groups were sampled on adjacent burned and unburned sand prairie for 3 years following a single spring burn. The abundance of all insects combined was significantly lower on the burned site than on the unburned site in the 1st yr postburn but not in subsequent years of the study. Of the selected insect groups, ants were significantly (P < 0.05) more abundant on the burned site than the unburned site for the 1st yr…

Evolutionary Ecology across Three Trophic Levels: Goldenrods, Gallmakers, and Natural Enemies

Student Database

Author: Abrahamson, Warren G.; Weis, Arthur E. Description: In a work that will interest researchers in ecology, genetics, botany, entomology, and parasitology, Warren Abrahamson and Arthur Weis present the results of more than twenty-five years of studying plant-insect interactions. Their study centers on the ecology and evolution of interactions among a host plant, the parasitic insect that attacks it, and the suite of insects and birds that are the natural enemies of the parasite. Because this system provides a model that can be subjected to experimental manipulations, it has allowed…
