Methods

Ecologists are focussing increasingly on explaining the structure of communities by enriching traditional food web data with additional information. Many community studies collect either the food web, species' body masses, or abundance data, and an ever increasing number of studies measure two or three of these data types and/or additional data. Various combinations of data allow different properties to be explored and different hypotheses to be tested.

Cheddar provides many relevant published methods. The examples below illustrate the different views of community data that contain different combinations of trophic links, body masses, and abundance data, following Cohen et al 2003, without going into detail. Most examples use the dataset of Tuesday Lake sampled in 1984 (Cohen et al 2003; Jonsson et al 2005).

{% for method in methods %} {% endfor %} Trophic links Body mass Numerical abundance Description {{ '✓' if 'TRUE'==method.links }} {{ '✓' if 'TRUE'==method.M }} {{ '✓' if 'TRUE'==method.N }} {{ method.description }}

Functions: {% for f in method.functions.split(' ') %} {{ f }} {% endfor %}

{% if method.references %}

References: {% for f in method.references.split(';') %} {{ f }}; {% endfor %}
