Resumo: |
The relationships between fig trees and their hosts, as well as other traits, can be determinated by factors that act in response to the environment (ecological) wich are and the historical factors expressed in filogeny (evolutionary). The occurrence of a species in a habitat is the result of the balance between ecological and niche conservation processes. Thus the aim of this study is to investigate if the differences in the occurrence of the fig trees in the available habitats are determinated by historical or current factors. The work was performed in the forestry remnants (capões) in south Pantanal where a survey of the fig trees found was conducted and identified the habitat (hemiepiphyte or non-hemiepiphyte) as well as the species of the hosts. We find that the niches of the fig species were not phylogenetically conserved within the group (genus Ficus) and that the current processes are determining their niche. There was specialization on the species of hosts. We discuss how the fig species coexists the capões of south Pantanal. |
