As in other areas, invertebrates dominate both the terrestrial and aquatic faunas of the mallee in terms of numbers of individuals, numbers of species and biomass. For example, over 150 species of ant, a dominant mallee group, have been found in a 50 x 50m square over one year. Invertebrates have an essential role in ecosystem structure and function; they are involved in feeding on plants, nutrient recycling, parasitism, predation, scavenging, pollination, and by occupying the lower levels of the food chain, they are the main food of many species of reptiles, birds and mammals. No systematic invertebrate studies or surveys have been undertaken on Gluepot Reserve as yet. However, some information is available on ant species:  The Ants of Gluepot
