Organisms can use heuristics (\u2018rules of thumb\u2019) based on available information to decide when to leave the patch. Here we investigate proximate patch departure heuristics in two species of giant, brainless amoeba: the slime moulds Didymium bahiense and Physarum polycephalum. We explicitly tested the importance of information obtained through experience by eliminating chemosensory cues of patch quality. In Physarum polycephalum, patch departure was influenced by the consumption of high, and to a much lesser extent low, quality food items such that engulfing a food item increased patch residency time. Physarum polycephalum also tended to forage for longer in darkened, \u2018safe\u2019 patches. In Didymium bahiense, engulfment of either a high or low quality food item increased patch residency irrespective of that food item's quality. Exposure to light had no effect on the patch residency time of D. bahiense. Given that our organisms lack a brain, our results illustrate how the use of simple heuristics can give the impression that individuals make sophisticated foraging decisions.<\/jats:p>","DOI":"10.1242\/jeb.116533","type":"journal-article","created":{"date-parts":[[2015,2,27]],"date-time":"2015-02-27T02:17:15Z","timestamp":1425003435000},"source":"Crossref","is-referenced-by-count":21,"title":["Slime moulds use heuristics based on within-patch experience to decide when to leave"],"prefix":"10.1242","author":[{"given":"Tanya","family":"Latty","sequence":"first","affiliation":[{"name":"Department of Plant and Food Science, Faculty of Agriculture and the Environment, University of Sydney, NSW, 2015, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Madeleine","family":"Beekman","sequence":"additional","affiliation":[{"name":"Behaviour and Genetics of Social Insects Lab and Centre for Mathematical Biology, School of Biological Sciences A12, University of Sydney, NSW 2006, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"237","reference":[{"key":"2021042509135821500_JEB116533C1","doi-asserted-by":"publisher","first-page":"413","DOI":"10.1086\/603629","article-title":"Bumblebees learn to forage like Bayesians","volume":"174","author":"Biernaskie","year":"2009","journal-title":"Am.
