A data frame of species-specific parameter values.
Optional interaction matrix of the species (predator species x prey species). Entries should be numbers between 0 and 1. By default all entries are 1. See "Setting interactions" section below.
The smallest size of the resource spectrum. By default this is set to the smallest value at which any of the consumers can feed.
Sets the size of the eggs of all species for which this is not
given in the w_min
column of the species_params
dataframe.
The largest size of the consumer spectrum. By default this is
set to the largest w_inf
specified in the species_params
data
frame.
The number of size bins in the consumer spectrum.
The allometric growth exponent. This can be overruled for individual
species by including a n
column in the species_params
.
Allometric exponent of search volume
Expected average feeding level. Used to set gamma
, the
coefficient in the search rate. Ignored if gamma
is given
explicitly.
Coefficient of the intrinsic resource carrying capacity
Scaling exponent of the intrinsic resource carrying capacity
Coefficient of the intrinsic resource birth rate
