Evidence for secondary seed dispersal by rodents in Panama

Abstract: The data presented show thatVirola nobilis (Myristicaceae), a bird/mammal-dispersed tree species in Panama, may also be dispersed by a terrestrial rodent, the agouti (Dasyprocta punctata). Using a thread-marking method, we observed that agoutis scatterhoardedV. nobilis seeds that they found both singly or in clumps. Seed removal and seed burial rates were strongly affected by features of forest habitats, such asV. nobilis tree richness (rich vs poor) and/or forest age (old vs young), but not by seed dispersal … Show more

“…In Central Panama, such information has been compiled for most plant species by S. J. Wright and O. Calderón from their ovwi observations and numerous studies of frugivorous animals (e.g. Forget & Milleron 1991;Kalko et al 1996b;Milton 1980;Poulin et al 1999;Wehncke et al 2003) and animal-dispersed plants (e.g. Croat 1978;Martin 1985).…”

“…The impact of ant dispersal activity is evident in the exceptionally high Simarouba seedling densities observed near leafcutter-refuse piles located near reproductive trees, in comparison to other sites without ant nests nearby (B. D. Hardesty, unpublished data). While ants and dung beetles move only small seeds, scatter-hoarding rodents such as agoutis are important as seed dispersers, as well as seed predators, of many particularly large-seeded plant species (Forget & Milleron 1991). In addition to their effect on seed movement, seed treatment by secondary dispersers can be important to seed survival; in particular, seed burial by agoutis, ants or dung beetles can help seeds escape subsequent prédation by other insects and rodents (Wright & Duber 2001).…”

“…This seed movement away from the parent may involve a complex relationship between plant and seed disperser, which influences the germination and seedling establishment (FORGET and MILLERON, 1991). Studies on seed dispersal coupled to germination are important tools for conservation projects and forestry as well as for understanding the structures of the plant communities and their regeneration processes (HOWE, 1984).…”

“…Grasses are found to exhibit a hump-shaped effect on Brant's voles in grassland because of a trade-off between food supply and habitat preference of voles [29]. Some animals, acting as seed eaters and seed dispersers in forests simultaneously, show both negative and positive effects on plants [27,[30][31][32]. Interactions between some ant and aphid species can be shifted from positive at low aphid densities to negative or neutral at high density [16].…”
