Code and example data to calibrate the niche model of food webs based on allometric relationships

#### READ ME

###################################

The code has the following structure

# 1. Loading of an artificial dataset of i) predator-prey interactions, ii) body size distribution, iii) hypothetical species presence/absence lists

# 2. Definition of functions run for the analysis

# 3. Calculation of the observed parameters for the niche model

# 4. Inferrence of the parameters for all species in the metaweb

## Name of the parameters of the niche model

# n: niche position along the niche axis

# c: centroid of the niche

# r: range of the niche
