Abstractions, Analysis Techniques, and Synthesis of Scalable Control Strategies for Robot Swarms
… of the mechanics of cooperative retrieval in Aphaenogaster cockerelli ants. The correctness of the abstractions and the correspondence of the evolution of the controlled system to the target behavior are validated with computer simulations. The investigated applications form the building …

Anting Behavior in Birds: Ant Selection and Effect of ant Chemistry on Feather Ectoparasites
… Myrmicinae. <em>Camponotus, Lasius</em> and <em>Aphaenogaster</em> ants were preferred and <em>Pheidole</em> and <em>Crematogaster</em> ants were rejected. Preferred ants were significantly more active than ignored ants and lacked aggressive stinging and biting behaviors. Temperature and humidity …

Consequences of interaction between the native ant community and an invasive plant (Euphorbia esula)
… on growth or reproductive output of lab-reared Aphaenogaster rudis, a common seed-dispersing North American ant. Lastly, the exclusion of ants to E. esula stems with active nectar glands had no effect on plant reproduction or incidence of herbivory, indicating that ants are not …

Global change effects on ant-mediated seed dispersal
… colonies of their mutualist seed disperser, Aphaenogaster rudis. This design allowed us to collect high-resolution data on how ants interacted with seeds under different climate change scenarios that incorporated warming temperatures and altered precipitation. We found that warming effects …
