Identification of compounds was based on retentiontime matching and coinjection with standards. Similarly, a higher retentiontime was associated with higher parity. Individual sugars were identified by retentiontime, corrected for relative recovery of internal standard, and expressed as mole ratios. Mean retentiontime is the average number of hours it took a primate to pass a food item. Each molecule, corresponding to a peak on the chromatogram, was characterized by its retentiontime. Identification of the compounds was generally made by mass number and relative retentiontime. By coinjecting these hydrolysis products with authentic standards, the retentiontime of each isomer was established. Identification was by means of retentiontime only. We estimated the seed retentiontime of each focal animal. High feeding levels decrease retentiontime in the gastrointestinal tract and thus reduce the coefficient of digestibility, on average 0.03 units per feeding level. Then, a high retentiontime would allow the disperser to move further away from the source tree and thus disperse the seeds further. Gulped seeds can be deposited under the parent tree when retentiontime is shorter than duration of visits. Chemical identification was performed by comparison with the retentiontime and mass spectra fragmentation pattern of authentic standards. Phenylalanine (mass 165) was identified by its known retentiontime from chromatography. These examples are from corpora and from sources on the web.
