Grants are sorted by topic (e.g. ornithology, evolution...) to make it easier to find those you can apply to.
The website is designed for postdocs, so only grants to which postdocs can apply to are presented.
Obviously there is some overlap: you may apply to an 'ecology' grant to work on snakes and vice-versa.
Note that for most society-based grants, you need to be a member of the society beforehand. There may also be some citizenship restrictions, so make sure to visit the webpage (to see if you are eligible) before starting to write a proposal.
