Evaluating the structure of commensalistic epiphyte-phorophyte networks: a comparative perspective of biotic interactions.

Epiphytic vascular plants comprise an essential part of the tropical flora and are a key component for ecosystem functioning. Some recent studies have used a network approach to investigate the interaction of epiphytes with host phorophytes at the community level. However, knowledge on commensalistic epiphyte-phorophyte network structure still lags behind with regard to other biotic interaction networks.

Mycorrhizal preferences and fine spatial structure of the epiphytic orchid Epidendrum rhopalostele.

Premise Of The Study: The presence of compatible fungi is necessary for epiphytic orchid recruitment. Thus, identifying associated mycorrhizal fungi at the population level is essential for orchid conservation. Recruitment patterns may also be conditioned by factors such as seed dispersal range and specific environmental characteristics.
