The results of nocturnal visual surveys are influenced by lamp properties

January 1, 2009

We conducted standardized visual searches at night for brown treesnakes (Boiga irregularis) and geckos, where we alternated between spotlight and floodlight lamps. Floodlights rendered us 25% more snakes and 71% more geckos than did spotlights. We show data on searcher variability and discuss what might affect the relative benefit of different lamp types. ?? 2009 Brill Academic Publishers.
