I don't know of any RAW, but I would adjucate on a case-by-case basis depending on how "Earthlike" the plane is. The Beastlands? Sure, no penalty - I might even allow a slight bonus, since the place is essentially "nature to the max". Arcadia or the Seven Heavens? With a penalty - such places may appear to have "animals" and "plants" but they usually have "extra" abilities (trees that walk, beasts that talk), as well as appropriate templates (celestial, fey, etc.) that may change their abilities and/or behavior. Most of the Lower Planes are hostile enough that normal animals and plants are unlikely to exist. "Ideal" planes such as Mechanus, Nightmare, Shadow, et al, and "Incorporeal" planes like Astral and Etheral, are likewise usually too "weird" for Material-plane knowledge to apply. Elemental planes often have animal-like critters (eg flame snakes, fire bats, and ash rats from the Plane of Fire) but these are idealized forms made of elemental-stuff and unlikely to act the same way as Material critters.
