1. Demonstrating the mechanism involved in changing a colony decision against a pre-existing sub-optimal choice during nest relocation of Myrmencia nipponica (review) By YuYu KISU
2. 1 decision pheromone Myrmecina nipponica Pheromone trail against pre-existing information Cronin (2013a)
3. 2 Possible mechanisms ‘No entry’ pheromone (Robinson et al., 2005) Up/Downregulation of pheromone deposition (Czaczkes et al., 2024; Czaczkes & Heinze, 2015) Quorum threshold change (Cronin, 2013b) etc. Very rare…costly...?! (Goldberg & Bloch, 2023) Simulation analysis & model (Cronin, 2014; Marshall et al., 2009) There are studies… (I haven’t read yet…)
4. 3 Future directions Not really found… (Cronin’s lab member) Worth trying empirically with perturbation!? Worth trying with M. nipponica? 𝑓(𝑥) Wulfila (2008) Choi & Vander Meer (2012)
5. 4 Significance Generated by Microsoft Copilot (2024) • Multi-faced strategies ants use to adapt dynamic environmental conditions • Combined use of pheromone trails and another means of decision making • Social values • Answers to some philosophical questions
