% Structuring a talk is a difficult task and the following structure
% may not be suitable. Here are some rules that apply for this
% solution:

% - Exactly two or three sections (other than the summary).
% - At *most* three subsections per section.
% - Talk about 30s to 2min per frame. So there should be between about
%   15 and 30 frames, all told.

% - A conference audience is likely to know very little of what you
%   are going to talk about. So *simplify*!
% - In a 20min talk, getting the main ideas across is hard
%   enough. Leave out details, even if it means being less precise than
%   you think necessary.
% - If you omit details that are vital to the proof/implementation,
%   just say so once. Everybody will be happy with that.

\section{Introduction}

\subsection{Predator-Prey Background}

\begin{frame}{Predator-prey model}
  % - A title should summarize the slide in an understandable fashion
  %   for anyone how does not follow everything on the slide itself.

  \begin{itemize}
  \item
    Predator-Prey models are differential equations that model the interaction between two species. One species gains from this interaction while the other is hurt.
  \item
    These models are used to study the dynamic behavior of interacting species.
  \item
    The dynamics of each population depends upon the other.
  \end{itemize}
\end{frame}

\begin{frame}{Two Patch Model}
\begin{itemize}

\item
There are two different populations in two different geographic populations, but the populations can disperse from one patch to the other.
\item
Prey and predator may have different diffusion coefficients.
\end{itemize}

%\caption{The figure shows the oscillations in population that predator-prey models attempt to recreate.  \label{fig1}}
\end{center}
\end{figure}
\end{frame}


\begin{frame}{Lynx and Hare}
\begin{figure}[t]
\includegraphics[width=0.25\textwidth,keepaspectratio]{snowshoehare.png}
%\caption{The figure shows the oscillations in population that predator-prey models attempt to recreate.  \label{fig1}}

%\caption{The figure shows the oscillations in population that predator-prey models attempt to recreate.  \label{fig1}}
\end{figure}
\end{frame}

\begin{frame}{Lynx and Hare}
  \begin{itemize}
    \item
      The Lynx-Hare model is the most well known applied predator-prey model.
\begin{figure}[t]
\begin{center}
\includegraphics[width=0.4\textwidth,keepaspectratio]{Lynx-Hare.png}
%\caption{The figure shows the oscillations in population that predator-prey models attempt to recreate.  \label{fig1}}
\end{center}
\end{figure}
\item
The Hudson Bay Company kept records of the populations over one hundred years. This is possibly the most pure example of predator-prey dynamics in nature.
  \end{itemize}
\end{frame}


\subsection{Synchrony}

\begin{frame}{Introduction}
\begin{itemize}
\item
Synchronization is the process in which oscillations attain the same frequency based on their coupling.
\item
Due to the diffusion, along with other factors, between two patches, the populations in each patch may become synchronized over time.
\end{itemize}
\end{frame}

\begin{frame}{Examples}
\begin{figure}[t]
\includegraphics[width=0.5\textwidth,keepaspectratio]{Synchronyexamples.png}
\caption{Coupled pendulums are typical coupled oscillators which may synchronize.}
\end{figure}
\end{frame}

\caption{Fireflies synchronize their flashes in order to extend the distance the light can be seen.}
