Applying Wet Sieving Fecal Particle Size Measurement to Frugivores: A Case Study of the Eastern Chimpanzee (Pan Troglodytes Schweinfurthii).

FPS has not been investigated systematically in frugivores, and important methodological problems remain. In particular, food items that are not chewed may skew estimates of FPS. We address such methodological issues and also assess the influence of diet type and age on FPS in wild chimpanzees.en-USAnatomyAnthropologyJournal Article2019-10-2910.1002/ajpa.23225
