The Southwestern Association of Naturalists each year grants Bruce Stewart Student Travel Awards to help defray travel and meeting expenses for students attending the annual meeting. For a given year, these awards are given to student applicants outside the host country who are giving an oral or poster presentation. To receive this award, students must be current SWAN members. Students who have received two travel awards previously are ineligible. Specific instructions and deadlines (generally 1 February) for online applications are posted each year on the SWAN website.
