Abstract

This study examines whether the lizard Podarcis lilfordi is a legitimate disperser of the rare Mediterranean plant Withania frutescens by using the biochemical test of triphenyl-2H-tetrazolium chloride for testing seed viability. This lizard eats the fresh fruits of the plants and defecates intact seeds which have been retained 1 to 3 d in their gut. Viability of seeds recovered from faeces was very high and comparable to the viability of fresh seeds. Seed dispersal by this lizard in the Balearic islands may facilitate population expansion of this rare plant in the Balearics.
