Assessing the potential for intraguild predation among taxonomically disparate micro-carnivores: marsupials and arthropods
For the first time, we present evidence that competition and intraguild predation may be occurring between taxa as disparate as marsupials and spiders. Despite small sample sizes, major overlap (>75% similarity) was found in diet and temporal activity, and moderate overlap in microhabitat use between wolf spiders (<i>Lycosa</i> spp.) and the lesser hairy-footed dunnart (<i>Sminthopsis youngsoni</i>). This study represents a new and unique insight into the intricacies of complex desert ecological interactions and has the potential to represent the most taxonomically disparate example of intraguild predation that has been reported.
