Abstract
Many angiosperms depend on animals for their pollination. Although most of the interactions between plants and pollinators do not seem to be so peculiar, everything seems to involve some degree of mutual adaptation between flowers and animals. Floral morphology is one of the most important aspects of plant-pollinator interactions, because it drives the floral resource accessibility by pollinators. This paper aims to propose and validate a methodology to test hypothesis on morphological correlation between flowers and their pollinators. A temporal series approach was made as an estimation of observational effort. The morphometry of cord and curvature of flower tubes and hummingbird bills were used as descriptors for an adjustment test made by logistic regression. In this modeling scale, with four bromeliads and seven hummingbird species, we rejected the hypothesis of the existence of morphological restriction imposed by bromeliads on the hummingbird selection, by means of its bill length or curvature.
