environR Documentation

Parameters associated with environmental effects and stochasticity.

Description

See vignette("internals", "gameofclones") for more information and for the exact values used.

Usage

environ

Format

A list of length 9:

harvest_surv

Numeric vector of length 1 for aphid survival rate at harvesting.

disp_aphid

Numeric vector of length 1 for dispersal rates between fields for aphids, adult wasps.

disp_wasp

Numeric vector of length 1 for dispersal rates between fields for aphids, adult wasps.

pred_rate

Numeric vector of length 1 for predation rate for aphids and non-adult wasps.

cycle_length

Numeric vector of length 1 for time between harvests (typical for alfalfa).

field_disp_start

List of length 2, each item of which contains a 1-length numeric vector indicating the day at which aphids begin dispersing for 20ºC (lowT) and 27ºC (highT). It's assumed that only adults are dispersing, but the day at which this occurs depends on how quickly the aphids are developing.

sigma_x

Numeric vector of length 1, indicating environmental std dev for aphids.

sigma_y

Numeric vector of length 1, indicating environmental std dev for wasps.

rho

Numeric vector of length 1, indicating environmental correlation among instars.
