The fitness landscape of a community of Darwin’s finches

<h3>Purpose</h3>

The dataset and script were developed to
<ol>
<li>estimate the fitness landscape for Darwin's ground finch species (<i>Geospiza</i> spp.) at El Garrapatero over 2003 to 2020, and </li>
<li> use the fitness landscape to consider theoretical expectations and previous empirical assertions regarding the topology of fitness and adaptive landscapes.
</li>
</ol>

<h3>Brief Methodology</h3>
To fulfil these aims, we used the data from our long-term monitoring site El Garrapatero on Santa Cruz in the Galápagos, Ecuador. We calculated lifespan as a fitness proxi from our recapture data to construct a fitness and adaptive landscape using the beak length and depth.

<h3>Data</h3>
Please, download and consult the <i>README</i> text file which explains the contents of <i>adaptive.landscapes.finches.zip</i>. The <i>.zip</i> file preserves the folder structure needed to run the scripts. The main program needed for the analysis is <a href="https://cran.r-project.org">R (open-source)</a>, but to fully reproduce all the code, <a href="https://imagemagick.org/index.php">ImageMagick (open-source)</a> and <a href="https://ffmpeg.org">FFMPEG (open-source)</a> programs.
