Landscape connectivity and predator–prey population dynamics

Jacopo Baggio | Published Thu Nov 10 19:35:38 2011 | Last modified Sat Apr 27 20:18:37 2013

A simple model to assess the effect of connectivity on interacting species (i.e. predator-prey type)

Positive feedback can lead to “trapping” in local optima. Adding a simple negative feedback effect, based on ant behaviour, prevents this trapping

A modified model of breeding synchrony in colonial birds

James Millington | Published Tue Jun 26 14:20:05 2012 | Last modified Sat Apr 27 20:18:19 2013

This generic individual-based model of a bird colony shows how the influence neighbour’s stress levels synchronize the laying date of neighbours and also of large colonies. The model has been used to demonstrate how this form of simulation model can be recognised as being ‘event-driven’, retaining a history in the patterns produced via simulated events and interactions.

Coupled Housing and Land Markets (CHALMS)

Nicholas Magliocca Virginia Mcconnell Margaret Walls | Published Fri Nov 2 20:20:30 2012 | Last modified Mon Oct 27 16:23:37 2014

CHALMS simulates housing and land market interactions between housing consumers, developers, and farmers in a growing ex-urban area.

Gunpowder battle tactics

Xavier Rubio-Campillo Jose María Cela Francesc Xavier Hernàndez | Published Wed Nov 20 13:14:07 2013 | Last modified Tue Nov 26 11:34:21 2013

This model simulates the dynamics of eighteenth-century infantry battle tactics. The goal is to explore the effect of different tactics and individual traits in the dynamics of the combat.

Adoption as a social marker

A model of innovation diffusion in a structured population with two groups who are averse to adopting a produce popular with the outgroup.

All Together Adder

J Kasmire Janne M Korhonen | Published Fri Dec 5 10:53:47 2014

The fourth and final extension to the standard Adder model to replicate the various interventions typically associated with Transition Experiments.

The model is an experimental ground to study the impact of network structure on diffusion. It allows to construct a social network that already has some measurable level of homophily, and simulate a diffusion process over this social network.

We provide a full description of the model following the ODD protocol (Grimm et al. 2010) in the attached document. The model is developed in NetLogo 5.0 (Wilenski 1999).

The effect of error on cultural transmission

Claudine Gravel-Miguel | Published Thu Nov 1 16:42:06 2012 | Last modified Sat Apr 27 20:18:48 2013

This is the replication of the experiment performed by Eerkens and Lipo (2005) to look at the effect of copying errors when specific traits are transferred from an individual to another.
