The oldest and most widespread\nmode of animal communication is chemical communication, which is particularly\nuseful in aquatic environments. In animals that are fully aquatic for only\npart of their lives, like amphibians, chemical communication at the larval stage is\ninteresting because it has not evolved for an immediate sexual advantage, making\nbehavioural assays easier to interpret. Dendrobates tinctorius is a neotropical poison\nfrog whose males transport tadpoles to small water pools where they develop until\nmetamorphosis. This study aims to determine with behavioral laboratory experiment\nwhich communication mode(s) are used by D. tinctorius tadpoles to detect\nanother individual. I hypothesized that tadpoles use a combination of visual and\nchemical cues for that purpose, as shown in other poison frog species. This detection\nshould manifest as an increased activity of tadpoles. Surprisingly, I found that tadpoles\nare the most active when exposed only to visual cues, indicating that tadpoles\nmight be more motion-orientated than previously thought. Tadpoles exposed exclusively\nto visual cues also di ered in their space use when compared to the control\ngroup (exposed to no cues): they spend more time closer to the individual they are\nseeing, which indicates that they are using their vision to gather more information\nabout their surroundings and possible threats.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2022-01-21T06:23:35Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2022-01-21T06:23:35Z (GMT).
