Category:Categories of biology requiring diffusion

This category contains categories related to biology that should contain no files.
Mostly the reason for avoiding files is that these categories are about a taxon when files would show a specimen that is only an example of the taxon, not the taxon.

This category is automatically filled when following templates are used:

• Position T: These categories groups taxa of the same rank. No files are allowed (Implemented in {{TaxonavigationAutoCategory/}})
• Position ' ': Endangered species categories. They should contain only IUCN diagrams, no specimen pictures (no template involved)
