This project tested the hypothesis that this disproportionate predation is a product of frequent encounter rates between the interactants due to high overlap in their diets and use of space and time. This data set focuses on overlap in the use of different microhabitats of wolf spiders (<i>Lycosa spp.</i>) and the lesser hairy­footed dunnart (<i>Sminthopsis youngsoni</i>) in the Simpson Desert, south­western Queensland Australia. Microhabitat use was determined by estimating the percentage cover of seven microhabitat variables and distance to nearest cover along trails left by individuals of each species­ group and a randomly orientated (control) trail for each actual trail as a measure of the availability of each microhabitat within the local environment. Trail length was also recorded and data was collected across 16 trapping grids at Main Camp during July and October (winter and Spring) in 2017. Differences in microhabitat use between trail types (actual vs control) and species (lycosids vs dunnarts) were assessed using non­metric multidimensional scaling (NMDS) and permutational analyses of variance (PERMANOVA). 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 <i>Lycosa spp.</i> <i>Sminthopsis youngsoni</i> Arid ecology Behavioural Ecology Predator-Prey Interactions AEKOS_species_common _names documentDigital TXT Potter_Dunnartlycosid_microhabitat_data documentDigital XLSX AEKOS_species documentDigital TXT ro-crate-metadata.json documentDigital HTML Unnamed resource documentDigital PNG
