Self-organized spectral adjustment in echolocation sounds within group-flying bats

Self-organized behaviour has been extensively studied in group dynamics in animals, with a strong focus on movement coordination in species like fish and birds. By contrast, far less attention has been paid to vocal interactions within animal groups. Here, we unveil a self-organi...

Sand Influx Effect on Barchan Steady-state Profile

In this study, based on the crest line model, a differential equation-based mathematical approach to dune dynamics, we investigate the effect of non-contact interactions between barchans through sand flow on their morphodynamics, which is a largely unexplored topic. Numerical cal...
