# Head dimorphism

Analysis of European eel head dimorphism in the Scheldt River basin

## Project structure

### Data-analysis

* `/src:`

    1. `Preprocessing.R`: upload eel data and change column names

    2. `Determine_headwidth.R`: Determine head width categories (narrow, broad and intermediate) and add head width data to the dataset

    3. `Analysis_model_distribution.R`: Determine model distribution (normality, unimodal and bimodal)

    4. `Condition.R`: Calculate relative condition factor according to Le Cren

    5. `Analysis_condition.R`: analyse if the relative condition differs according to head width, nested within maturation stages

    6. `Analysis_stadia.R`: determine the model distribution per maturation stadia and analyse if number of narrow and broad heads differ between maturation stadia

    7. `Link_onset_duration.R`: Link the onset and duration of migration to the dataset

    8. `Analysis_onset.R`: analyse if number of narrow and broad heads differ between months of onset

    9. `Analysis_swimspeed.R`: analyse if swim speed differs between eels with different head width class
