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
