No, that’s not the same as an organisation, but you may want to ask (via a PR) to have your package listed there. Note that I have an open PR to move the remaining ecology packages to biology (just to keep ecology consolidated - it’s tricky because the conventional split between Earth and Life sciences is meaningless).
It seems to me that the BioJulia organisation focuses almost exclusively on molecular biology. We have a more recent org for whole-organism ecology (https://github.com/EcoJulia/) where this might fit better (but still not perfectly).
