Trophic analysis of Phymaturus punae (Iguania: Liolaemidae): seasonal and sexual variation in the most southern region of the Argentina Puna. Rev. Mex. Biodiv. [online]. 2015, vol.86, n.4, pp.1004-1013. ISSN 2007-8706.  https://doi.org/10.1016/j.rmb.2015.06.013.

Knowledge of trophic parameters is very important to understand ecological relationships between species. Therefore, we describe and analyze the diet of a Phymaturus punae population, at seasonal and sexual terms. We analyzed the stomach contents of 39 specimens and we calculated percentage of each food category. We identified 16 food categories, grouping then into another 4. Phymaturus punae is herbivorous, and feeds mainly on stems-leaves -from individuals of the genus Adesmia-. In December, the most important food category was flowers, whereas during February was stems-leaves. Either for males and females, stems-leaves was the most consumed category. Nematodes were found in 100% of the sample.

Keywords : Herbivory; Nematodes; Diet; Food category.
