Evaluating ecological data – basic principles
How it works
Ecological data describe biological relationships such as species diversity, population sizes, abiotic factors, or interactions in ecosystems. The evaluation includes reading and interpreting tables, diagrams, and measured values, recognizing trends, drawing conclusions, and critically questioning data sources. It is important to distinguish between correlation and causation and to understand how interfering factors can influence results.
Note
Ecological data are evaluated by systematically comparing, recognizing patterns, and critically questioning relationships. Diagrams, tables, and text sources must be carefully read and interpreted in order to justify or refute ecological statements.

An example
A table shows that the number of ladybirds in a garden increased from April to June from 10 to 40. What can be concluded from this?
The data show that the ladybird population in the garden increased during the period from April to June. This may indicate favorable environmental conditions or a greater food supply. However, it is not certain whether the increase was directly caused by a single factor.
