This is a lab course intended to complement the lecture course (ENT3003). It is designed so that students concurrently enrolled in ENT3003 can better understand selected topics covered in the lecture. Students cannot take the lab course without also concurrently taking the lecture course. Students who have completed an equivalent ecology lecture course in a previous semester may be allowed to take this course with the instructor's permission, but it is not recommended because the lecture (ENT3003) and the lab (ENT3020) are not designed independently. Students who enroll in the lab course (ENT3020) without concurrently enrolling in the lecture course (ENT3003) and without the instructor's permission will automatically receive an F grade, regardless of their performance in the lab course (ENT3020).
