A strong conditional mutualism limits and enhances seed dispersal and germination of a tropical palm

Abstract: Seed predation and seed dispersal can have strong effects on early life history stages of plants. These processes have often been studied as individual effects, but the degree to which their relative importance co-varies with seed predator abundance and how this influences seed germination rates is poorly understood. Therefore, we used a combination of observations and field experiments to determine the degree to which germination rates of the palm Astrocaryum mexicanum varied with abundance of a small mammal … Show more

“…We did not measure ambient mast or small-mammal abundances at our study sites, but previous studies have found that the effectiveness of scatter-hoarders as dispersal agents varies with overall mast abundance (Vander Wall 2002, Jansen et al 2004, Moore et al 2007) and seedconsumer ratios (Sone et al 2002, Klinger and Rejma´nek 2010, Xiao et al 2013.

“…The low rate of damage to seedlings may also suggest that events such as fire, insects, pathogens, animal, or human-caused damage were minimal within the plantation system. Interactions among these factors normally do have effects on plant distribution and abundance (Silman et al 2003;DeMattia et al 2004;Klinger and Rejmánek 2010). These levels of survival can even further be improved if planting is carefully done by matching species to site characteristics (Shono et al 2007).…”

“…Soil texture is related to drainage, and it characterizes the bulk density, surface area, and air space in between soil particles, affecting the water-holding capacity and hydraulic conductivity of soils (Rawls et al 1982, Sollins 1998, Palm et al 2007). Topography also influences species distributions through its interaction with other environmental factors such as soil nutrients, hydrology, wind exposure, temperature and even biotic factors (Trichon 1997, Pausas and Austin 2001, Klinger and Rejmánek 2010). Its effect on plant performance is thus indirect, difficult to interpret and often site specific (Vormisto et al 2004).…”
