Population density of titi monkeys (Plecturocebus discolor) in Yasuní National Park, Ecuador
Dataset collected in 2010 using distance sampling methods to calculate the population density of titi monkeys (Plecturocebus discolor, formerly Callicebus discolor) around Estación Científica Yasuní (ECY) in the Ecuadorian Amazon (-0.67S, -76.40W).
Census data included as a CSV file, and information on dataset included in a README file. Dataset consists of titi monkey loud chorus responses to 68 playbacks of a loud chorus around the trail system of ECY.
Population density estimated using using Distance 6.0 with a hazard-rate key function and two cosine adjustments. Population density is estimated as 8.7±SE1.4 groups per km2, with a 95% confidence interval of 6 – 12 groups.
