Abbreviations as in Figures 1, 2, and 3. Seasonal effects We studied seasonal dietary shifts in Podareis lilfordi populations. Results from spring and summer samples are summarized in tables 6 and 7 respectively. In general, dietary diversity was lower during summer. The relative abundance in the diet of Coleóptera, Isopoda, and Formicidae exhibited significant variations (G-tests, in all cases ), Chilopoda (0 = , p>), Homoptera, Heterop- tera, and larvae (G = , p>) remained fairly constant. Hence, the seasonal die- tary shifts can be summarized in a higher importance of Coleóptera during spring and a predominance of Isopoda and Formicidae during summer. In fact, the trend to myrmecophagy is so strong that ants are the main prey even by volume (fig 6), what is particularly noteworthy given the small size of ant species involved. Also plant consumption is significantly higher during summer, concerning the proportion of individuals consuming plant matter (fig 7, Kruskal-Wallis analysis, H = , p = ), as well as the average volume of plants in stomachs or faecal pellets (fig 8, H = , ). The rather high proportion of pollen and nectar from summer samples of P lilfordi deserves special attention. This amount of nectar and pollen came from the Nitge lizards faecal pellets (fig 5). The spring diet of Nitge lizards is similar to that of the lizards of other islands (table 6) but with the arrival of summer trophic resour- ces seems to decline drastically in this islet (Pérez-Mellado pers. obs.) and the diet shifts to a highly herbivorous compositio
