\myblock[TranspBlock]{Introduction}{
    \textbf{Chirps} are the most common communication signals in weakly electric fish. They are characterized by \textbf{short frequency excursions} and are emitted during various social contexts. It is nearly impossible to reliably \textbf{detect and assign} chirps in freely interacting fish using only a Fourier transform. To overcome these limits, we developed a new method of \textbf{dynamic feature extraction} and classification.

\myblock[GrayBlock]{Conclusion}{
    \begin{itemize}
        \setlength\itemsep{0.5em}
        \item Our analysis is the first to indicate that \textit{A. leptorhynchus} uses long, diffuse and synchronized EOD$f$ signals to communicate in addition to chirps and rises.
        \item The recorded fish do not exhibit jamming avoidance behavior while close during synchronous modulations.
        \item Synchronous signals \textbf{initiate} spatio-temporal interactions.
