| Abstract: | During May 1999, feces baited pit-fall traps were run at the Welder Wildlife Refuge near Sinton, Texas, duplicating, in part, earlier sur veys of 1974 –75 and 1985. The results show a decline in the number of species of Scarabaeinae and a shift in species compo- sition. Possible explanations for the changes include vegetational-climatic differences over time and the recent increase in the number of the red imported fire ant. |
