Sondra Vega reported the results of a fascinating study of diet in nine Puerto Rican anoles. Using isotope analysis from tail tissue, she concluded that all species are to some degree omnivorous, not terribly surprising in some sense because a number of species have already been reported to eat fruits and berries. What is surprising is that there seem to be two discrete groups, suggesting that some species are more omnivorous than others. In particular, some are more carnivorous (cooki, monensis, pulchellus, and stratulus) and others more omnivorous (cristatellus, cuvieri, evermanni, gundlachi and krugi).
