Spatio-temporal structures in frog chorus with two species examined by laboratory experiments and mathematical modeling
Kanato Kawaguchi, Ryu Takeda, Ikkyu Aihara
Synchronization can be observed in various systems in physics and biology. The choruses of male frogs are known as an example of biological synchronization in which the well-organi…
Gradual emergence of temporal structures depending on the distance between neighboring callers in natural habitat of male treefrogs
Ikkyu Aihara, Ryu Takeda, Masahiro Shirasaka +3
Acoustic animals (e.g., insects and frogs) aggregate and produce sounds for mating. Well-organized chorus structures like call alternation and call synchrony indicate the importanc…
Wavy synchronization in locomotion of train millipedes
Momiji Yoshikawa, Ikkyu Aihara
The sophisticated control of many legs by millipedes and centipedes establish well-organized temporal structures such as wavy synchronization in their gate patterns. Quantification…
Excitatory and inhibitory interactions affect the balance of chorus activity and energy efficiency in the aggregation of male frogs: Theoretical study using a hybrid dynamical model
Ikkyu Aihara, Daichi Kominami, Yushi Hosokawa +1
We theoretically study the role of excitatory and inhibitory interactions in the aggregations of male frogs. In most frogs, males produce sounds to attract conspecific females, whi…
Interaction Mechanisms Quantified from Dynamical Features of Frog Choruses
Kaiichiro Ota, Ikkyu Aihara, Toshio Aoyagi
Interaction mechanism in the acoustic communication of actual animals is investigated by combining mathematical modeling and empirical data. Here we use a deterministic mathematica…
Landing Dynamics of a Seagull Examined by Field Observation and Mathematical Modeling
Yuri Eisaki, Ikkyu Aihara, Isamu Hikosaka +1
A seagull ({\it Larus crassirostris}) has a high ability to realize its safe, accurate and smooth landing. We examined how a seagull controls its angle of attack when landing on a…
