What does altitudinally mean?

"Altitudinally" is not a standard English word. It's likely a misspelling of altitudinally, which means "in relation to altitude".

Here's how you can use it:

* "The plant's growth is affected altitudinally, with higher altitudes resulting in shorter plants."

* "The bird's migration patterns are influenced altitudinally, with the birds flying higher in the winter."

Remember, "altitudinally" is a fairly uncommon word and might not be understood by everyone. You might be better off using a clearer phrase like "in terms of altitude" or "with respect to altitude" in most contexts.
