Traffic rules around the corner: walking of leaf-cutting ants at branching points in trunk trails
(Birkhauser Verlag Ag, 2017-11)
The existence of transport networks is vital for leaf-cutting ant foraging but may generate overcrowding, reducing the input of food into the nest. We studied how ants turn at branching points, a problematic sector for ant ...
Working in the rain? Why leaf-cutting ants stop foraging when it’s raining
(Birkhauser Verlag Ag, 2018-05)
Understanding how environmental factors modulate foraging is key to recognizing the adaptive value of animal behavior, especially in ectothermic organisms such as ants. We experimentally analyzed the effect of rain on the ...
Ant mimicry in the spider Myrmecotypus iguazu (Araneae: Corinnidae), with notes about myrmecomorphy in spiders
(American Arachnological Society, 2013-11)
We describe the mimetic relationship between the ant-like spider Myrmecotypus iguazu Rubio & Arbino 2009 (Araneae: Corinnidae) and the carpenter ant Camponotus sericeiventris Gue´rin (Hymenoptera: Formicidae), studied in ...
Plant odors trigger clearing behavior in foraging trails: do they represent olfactory obstacles?
(Elsevier Science, 2019-12)
Foraging trails of leaf-cutting ants may be exposed to plant material that interferes with foragers’ flux either by physically blocking it or due to secondary metabolites which affect insect behavior. We hypothesized that ...
The Effect of nest Size and Species Identity on Plant Selection in Acromyrmex Leaf-Cutting Ants
(Universidade Estadual de Feira de Santana, 2018-09)
Leaf-cutting ants are key organisms because their role as primary consumers and potential agricultural pests. However, their foraging ecology was mostly studied as response of extrinsic factors such as climate and plant ...
Traffic restrictions for heavy vehicles: Leaf-cutting ants avoid extra-large loads when the foraging flow is high
(Elsevier Science, 2020-01)
A better knowledge of the behaviors that reduce traffic congestions is essential to understand the success of the trail system despite of costs. Leaf-cutting ants use a trunk-trail system to transport leaf fragments into ...
Division of labor in work shifts by leaf-cutting ants
(Nature Publishing Group, 2021-04-22)
Foraging rhythms in eusocial insects are determined by the colony´s overall pattern. However, in leaf-cutting ant workers, individual rhythms are not fully synchronized with the colonies’ rhythm. The colony as a whole is ...
