Here, we tested whether lycosids have relatively high energy or nutrient contents compared to other invertebrates, and hence whether these aspects of food quality can explain selective predation of lycosids by <i>S.youngsoni</i>. Energy, lipid and protein composition of representatives of 10 arthropod families that are eaten by <i>S. youngsoni</i> in the Simpson Desert were ascertained using microbomb calorimetry, chloroform-methanol extraction and Dumas combustion. Differences between invertebrate groups were assessed using separate analyses of variance (ANOVAs) and appropriate post-hoc tests. These analyses were performed using this data. {"type": "Polygon", "coordinates": [[[138.40768, -23.74104], [138.75649, -23.74104], [138.75649, -23.54228], [138.40768, -23.54228], [138.40768, -23.74104]]]} 138.40768 138.75649 -23.74104 -23.54228 Arid ecology Behavioural Ecology Molecular Ecology Predator-Prey Interactions Species documentDigital TXT Species_list_scientific documentDigital TXT Energy_Nutr_data documentDigital XLSX ro-crate-metadata.json documentDigital HTML Unnamed resource documentDigital PNG
