Intervención de vertebrados en la diseminación de plantas vasculares en Inagu, Gran Canaria (Islas Canarias)
From the second author's data it has arisen that Corvus corax tingitanus -a local raven- has an assorted diet, consuming fruits (and seeds) of Opuntia ficus-barbarica, Chamaecytisus proliferus, Rubia fruticosa, Phoenix canariensis and Plocama pendula. The closest populations of the two latter species live in lower biotopes, warmer than the sampled site which is probably on suitable for the dispersed plants, despite the fact that the seeds are viable. Gallotia stehlini, an omnivorous lizard, has small territories and therefore eats just local fruits and/ or seeds of Rubia fruticosa and Teline rosmarinifolia. Erinaceus algirus, a primarily insectivorous hedgehog, appears to roam to far populations of Plocama. The seed rain does not seem to be a restriction but the'establishment of the plants, frequently blocked by the strong environmental contrasts among very close habitats.

| Summary: | From the second author's data it has arisen that Corvus corax tingitanus -a local raven- has an assorted diet, consuming fruits (and seeds) of Opuntia ficus-barbarica, Chamaecytisus proliferus, Rubia fruticosa, Phoenix canariensis and Plocama pendula. The closest populations of the two latter species live in lower biotopes, warmer than the sampled site which is probably on suitable for the dispersed plants, despite the fact that the seeds are viable. Gallotia stehlini, an omnivorous lizard, has small territories and therefore eats just local fruits and/ or seeds of Rubia fruticosa and Teline rosmarinifolia. Erinaceus algirus, a primarily insectivorous hedgehog, appears to roam to far populations of Plocama. The seed rain does not seem to be a restriction but the'establishment of the plants, frequently blocked by the strong environmental contrasts among very close habitats. |
