My research tests the Coping Model of Crowding as an explanation for the apparent increase in aggression among the Critically Endangered lemur, Coquerel's sifaka (Zaboomafoo!). Conducted in Ankarafantsika National Park, northwestern Madagascar, my thesis looks at the behaviour and ecology of sifaka groups from dawn to dusk through direct observation and handwritten data collection. Using a One Health approach, I'm comparing groups in low-density, intact forest with those in a crowded, human-modified tourist area to assess how habitat disturbance and crowding influence the species' social and spatial dynamics.
