“…They adjusted their activity level due to environmental stimulation (Gordon, 1996). As leafcutting ants do mass foraging, the mechanisms to organize the collective behavior in order to learn spatio-temporal cues are imbedded in the main means of navigation, the integration of paths and reference points (Wehner et al, 1990;Collett, 1992) and our experimental setup was designed for ants to use them. The increase in "pre-feeding" flow in the sucrose trail can be interpreted as anticipation.…”

“…Linnaeus’ floral clock (Gardiner, 1987) demonstrates the adaptive value of anticipating floral opening patterns, crucial for finding resources under specific environmental conditions (Crystal, 2009). In fact, the ability to anticipate the search for periodically available resources is observed in several animals, including rats (Wall et al, 2019), birds (Tello-Ramos et al, 2015), bees (Murphy and Breed, 2008; SILVA et al , 2008; SILVA et al, 2021) and neotropical ants (Schatz et al, 1999). Anticipation improves performance in environmental challenges (Reznikova, 2007), allowing preparation for stimuli and increasing the chance of a successful response (Cipolla-Neto et al, 1988).…”

The ability to anticipate periodically available resources is observed in several animals and improves performance in obtaining resources and adaptability. Spatio-temporal learning occurs when they associate the correct time and location of future events. We evaluate whether leaf-cutting antsAcromyrmex subterraneuscan anticipate the presence of sucrose and examine potential anticipatory effects. Five colonies were used in an experimental setup where, from a central tray, two trails in opposite directions gave access to either the sucrose or to nothing. For 21 consecutive days sucrose was offered at the same place and the same time. Cameras recorded the flow of individuals at 4 different phases: before feeding (10h00-11h00), pre-feeding (11h30–12h00), feeding (12h00-13h00) and after feeding (14h00-15h00). On the 22ndday sugar was not supplied. On the 21stday the ants were marked and the next day, observed. Our results shows that: (1) the ants responded positively to the stimulus presented by forming the foraging trail to collect sucrose; (2) before feeding there was no significant difference in ant flow between the trails, but after feeding, the ant flow was consistently higher on trail that led to sucrose, which we called a keep going behavior; (3) there was a progressive spatio-temporal learning, given that ants began to appear earlier in pre-feeding throghout the weeks; (4) on the 22ndday, the ants presented themselves 10 minutes in advance and remained in the correct place; (5) the marked ants indicated that even without any resource the empty place continued to be explored. The colonies were able to learn where and when to look for food. Due to the adjustment of the ants to the stimuli of the environment it was possible to prepare for the collection of sucrose and the success in foraging for the colony.Summary statementLeaf-cutting ants are capable of spatio-temporal learning and this process has relevance on mass foraging recruitment and overall social organization of the colony.

“…(REZNIKOVA, 2007). Existem animais que podem aprender quando e onde procurar por comida, como os ratos (WALL et al, 2019), os pássaros (TELLO-RAMOS et al, 2015), as abelhas (MURPHY e BREED, 2008), assim como as formigas neotropicais (SCHATZ et al, 1999).…”

“…Testes envolvendo estudos de cronobiologia vem sendo realizados para descobrir como ocorre o processo da atividade antecipatória ao alimento (do inglês: food antecipatory activity ou FAA) no organismo. Foi mencionada a hipótese de que um horário regular de alimentação poderia contribuir em melhorias na memória e no aprendizado, além de reduzir impactos fisiológicos e cognitivos negativos em humanos (WALL et al, 2019).…”
