Most large-seeded shrubs and trees from Mediterranean shrublands are either serotinous (canopy stored seeds) or myrmecochorous (ant-buried). It has been hypothesized that these traits evolved to prevent access to the seeds by rodents. Here we present the first field evidence of a third guild, scatter-hoarding of nuts in the genus Leucadendron (Proteaceae) from the south-west Cape. The rodent concerned is Acomys subspinosus, a small (< 20 g) south-west Cape endemic murid. Seeds are typically buried singly, less than 2 cm deep and at distances of up to 5 m from seed depots. This finding has implications for the understanding of the evolution of myrmecochory and serotiny in shrublands. It extends the evolution of cached-nuts to a new family and is one of the first records of scatter-hoarding, outside of forests, in the southern hemisphere.
Keywords: Cape Mediterranean shrublands, myrmecochory, rodents, scatter-hoarding, seed dispersal, serotiny.
