Gaussian.tolerance: Bell-shaped tolerance function

In comsimitv: Flexible Framework for Simulating Community Assembly

Description

It calculates probability of seedling's survival from their trait related to habitat filtering and the local environment.

Usage

Gaussian.tolerance(
  trait.values,
  env,
  env.trait = "trait.a",
  sigma.a = 0.001,
  ...
)

Arguments

trait.values	Dataframe of all traits
env	Vector of environmental conditions in the local communities
env.trait	Name of trait related to environmental tolerance
sigma.a	Tolerance width (same for all species)
...	Any additional parameters

Details

It assumes that probability of seedling's survival is maximal if the local environment has the same value as its trait. Survival probability decrease as environmental value departs from the optimum according to a Gaussian (bell-shaped) curve. The speed of decrease depends on the tolerance width parameter (sigma.a).

Value

A matrix of survival probabilities, communities in rows, species/individuals in columns
