Do ethnobotanists study the effects of plants on various animals?

Ethnobotanists primarily focus on the relationships between people and plants, particularly how different cultures use plants for medicine, food, and rituals. While their main interest is in human interactions with plants, some may also investigate the effects of plants on animals, particularly in the context of traditional knowledge or ecological interactions. However, the study of plant effects on animals is more typically the domain of other fields, such as ecology or pharmacology.
