Resumen:
Abstract. ? We describe here the feeding habits of the Yellow-spotted
River turtle (Podocnemis unifilis, n=20),
Geoffroy?s side-necked turtle (Phrynops geoffroanus, n=10), and Gibba
turtle (Mesoclemmys gibba, n=4) from
central Peru, Pasco Department, and evaluate food overlap between them. P. unifilis showed a generalist feeding
habit, ingesting animal and plant matter, but tending to be herbivorous, as
plant matter made up 62.9% of the volume versus 3.9% for animal material. The
most important items in P. unifilis
diet were seeds from the Fabaceae (Leguminosae) family and bark. P. geoffroanus and M. gibba also had generalist feeding habits. The most important
items for P. geoffroanus were
insects, especially Libellulidae larvae, and plant material. M. gibba ingested insects, fish,
crustaceans, unidentified plant matter, bark, leaves, stem, and algae, being
plant matter more representative by frequency and volume. Food partitioning was
observed between P. unifilis and P. geoffroanus, and both species showed
a discrete food overlap with M. gibba.
This is the first quantitative dietary study of Peruvian freshwater turtles,
and the first diet analysis of wild M. gibba
in the Amazon basin.
