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 (<i>Plecturocebus discolor</i>, formerly<i> Callicebus discolor</i>) around Estación Científica Yasuní (ECY) in the Ecuadorian Amazon (-0.67S, -76.40W). <br>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. <br>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. <br>Data used in: S Papworth (2012) Small scale human-primate behavioural interactions in Amazonian Ecuador.
