Quintral seed dispersal by The Monito del Monte Monito del monte

Monito del monte

The Monito del Monte plays a crucial role in shaping the spatial structure of quintral.

Seed dispersal is a process that shapes the spatial structure of plant populations. For example, affects the distribution of regeneration, the total area occupied by populations of plants and geographical distribution of species. It is still unclear how the spatial aggregation of seeds produced dispersal by animals may affect the spatial scale of plant recruitment. In this sense, parasitic plants such as mistletoe quintral or ( Tristerix spp.) Are ideal for studying the spatial consequences of seed dispersal because seeds of these plants do not germinate or down if they are dispersed by animals. Garcia and colleagues studied the quintral ( Tristerix corymbosus ) and its only seed disperser, the Monito del monte ( Dromiciops gliroides ) in a temperate rainforest near Bariloche. The authors assessed the abundances of quintral and monkey using an approach that aimed to break the structure spatial populations of mistletoe and marsupial at different spatial scales. The study reports that seed dispersal by Monito del Monte plays a crucial role in shaping the spatial structure of quintral. This would occur through the adult fruit tracking by the monkey and the generation of patches quintral rods because of their dispersion. Thus, the Monito del Monte generate a positive interaction between adults and their descendants quintral. Similar effects of the role of dispersal in the spatial distribution of plants may be generalized to other plants in their dispersal are strongly associated with the distribution of the fruits and those plants that the probability of germination of the seeds dispersed is higher than non-dispersed.
