Social life and sanitary risks: evolutionary and current ecological conditions determine waste management in leaf-cutting ants
TLDR
Empirical results showed that high soil surface temperatures reduce pathogen prevalence from LCA waste, highlighting the adaptation of organisms to the hygienic challenges of social living, and illustrating how sanitary behaviours can result from a combination of evolutionary history and current environmental conditions.
Specialization and group size: brain and behavioural correlates of colony size in ants lacking morphological castes
TLDR
The relationship between colony size and brain region volume was task-dependent, supporting the task specialization hypothesis and suggesting that workers specialized in defence may have reduced learning abilities relative to leaf-ants.
Leaf-folding response of a sensitive plant shows context-dependent behavioral plasticity
TLDR
Habituation-like plasticity in a plant thigmonastic response that conforms to expectations of behavioral ecology theory usually applied to animals is shown.
Plant Killing by Mutualistic Ants Increases the Density of Host Species Seedlings in the Dry Forest of Costa Rica
TLDR
The benefit reported here for the ants could be in conflict with the host plant, especially when the plant has rhizomal reproduction.
Ability to reorient is weakly correlated with central-place versus non-central-place foraging in acacia ants
TLDR
It is found that the ability to reorient was not consistently associated with foraging ecology, although the species least able to recover after disorientation was an acacia ant, and the species performing best after dis Orientation was a central-place forager (P. gracilis).
Information transfer in head-on encounters between leaf-cutting ant workers: food, trail condition or orientation cues?
TLDR
The results do not support the hypotheses that workers exchange information about trail condition and orientation in head-on encounters, but suggest that workers acquire food information.
Blind trust in unblinded observation in Ecology, Evolution, and Behavior
We survey 492 recent studies in the fields of ecology, evolution and behavior (EEB) to evaluate potential for observer bias and the need for blind experimentation in each study. While 248 articles
Branching angles reflect a trade-off between reducing trail maintenance costs or travel distances in leaf-cutting ants.
TLDR
It is suggested that branching angles represent a trade-off between reducing maintenance work and shortening travel distances, illustrating how animal constructions can adjust to diverse environmental conditions and may help to understand diverse networks systems, including urban travel networks.
Acacia trees with parasitic ants have fewer and less spacious spines than trees with mutualistic ants
TLDR
It was found that parasite-inhabited trees had fewer swollen spines than ant-defended trees, suggesting that spines serve as mechanical protection against herbivory.
