Antarctic Moss Relative Abundance Model with R Code

An R model estimates species relative abundance from presence-absence data. The Australian Antarctic Data Centre provides the code, demonstrated with Antarctic moss data. The model was last updated in 2013.

Use Cases

• Estimate relative abundance from presence-absence data using the provided R model.
• Analyze spatial patterns along environmental gradients like water availability using the example dataset.
• Model temporal changes in species composition between 2000 and 2013 as demonstrated in the code.

Strengths

• Model is demonstrated with two concrete examples (spatial and temporal).
• Code is specifically designed for presence-absence data, a common ecological data type.

Limitations

• No raw dataset or column information is provided, only model code.
• The example data and model are from 2013, potentially using outdated methods.
