Do leaf-cutter ants Atta colombica obtain their magnetic sensors from soil?

How animals sense, process, and use magnetic information remains elusive. In insects, magnetic particles are candidates for a magnetic sensor. Recent studies suggest that the ant Pachycondyla marginata incorporates iron-containing particles from soil. We used leaf-cutter ants Atta colombica to test...

Homeward orientations under shifted fields suggest that ants calculated a path-integrated vector using proprioceptive information. Strikingly, ants from the soil-free colony also had magnetic particles; yet, as observed by ferromagnetic resonance, these particles differed from those in soil-exposed ants and were not associated with a magnetic compass sensitive to this experimental manipulation.application/pdfhttps://doi.org/10.1007/s00265-013-1621-7ISSN: 0340-5443EISSN: 1432-0762https://repository.urosario.edu.co/handle/10336/25915engSpringer Nature6255Behavioral Ecology and SociobiologyVol. 68Behavioral Ecology and Sociobiology, ISSN:0340-5443;EISSN:1432-0762, Vol.68 (January, 2014); pp.55-62https://link.springer.com/article/10.1007/s00265-013-1621-7Restringido (Acceso a grupos específicos)http://purl.org/coar/access_right/c_16ecBehavioral Ecology and Sociobiologyinstname:Universidad del Rosarioreponame:Repositorio Institucional EdocURHomingNavigationOrientationPath integrationProprioceptionDo leaf-cutter ants Atta colombica obtain their magnetic sensors from soil?¿Las hormigas cortadoras de hojas Atta colombica obtienen sus sensores magnéticos del suelo?articleArtículohttp://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/resource_type/c_6501Riveros Rivera, Andre JosafatEsquivel, Darci M.
