AnimalTraits is a curated database containing body mass, metabolic rate and brain size measurements across a wide range of terrestrial animal taxa. The database is described in the (as yet unpublished) paper:
Herberstein, M. E. et al. 2021. AnimalTraits: a curated animal trait database for body mass, metabolic rate and brain size
The database and associated software can be freely reused with no restrictions. If you use the database in your research, we request that you cite the paper, and, when possible, also cite the relevant original data sources that are identified in the database.
The distinctive value of this new animal trait database is four-fold:
- Open access: the data are openly available to researchers without restrictions;
- Taxonomic breadth: the database includes a broad taxonomic range of terrestrial animal species including several groups of tetrapods and arthropods, as well as molluscs and annelids;
- Clean, empirical data: all data are sourced from the original publication that made and reported on the included measurements, and are entered into the database using the original metrics - all subsequent transformations can be applied to these original data, meaning it is eminently reusable by future researchers;
- Annotation: we have included useful methodological metadata that allow researchers to filter the dataset as needed.
The buttons at the top of this page provide download access to the database.
The database can be downloaded as either a UTF-8 encoded CSV file or as an Excel (.xlsx) file. UTF-8 encoding is used so that accented characters in the references are represented correctly. Some software assumes that CSV files are UTF-8 encoded, however in some situations it is necessary to specify the encoding when opening a CSV file. To open such a file in Microsoft Excel, use the Text Import Wizard. If reading the file using base R, use
read.csv(file, encoding = "UTF-8").
Download docs button provides access to a CSV file that documents the columns in the database. The Excel version of the database contains the column documentation as a second worksheet.
