Diagnóstico vegetal e percepção da população sobre herbáceas e as suas interações ecológicas em áreas verdes urbanas

Abstract

Studies on urban ecology have grown over the years due to the potential of these urban ecosystems to contribute to ecological, social and aesthetic functions. Herbaceous plants stand out in these ecosystems and are essential for species maintenance. The present dissertation aimed to carry out the floristic survey, to characterize the pollination and dispersal syndromes of the species as well to verify the previous knowledge and the perception of the population on aesthetic aspects and of the ecological interactions that involve herbaceous in urban green areas. The study was developed in João Pessoa, Paraíba. The data collection was carried out in 23 public squares belonging to 10 neighborhoods of the city. For sampling of the flora, the 1mx1m quadrant method was used. In order to classify the pollination and dispersal syndromes, morphological characters, odor and resources offered to the biotic agents were analyzed. The analysis of environmental perception was done through semi structured questionnaires. The articles intend to indicate the floristic composition, the diversity indexes and similarity of the species present in the urban green areas of João Pessoa, characterizing the syndromes of pollination, dispersal and the respective patterns of syndromes diversity in the city zones. In addition, it was intended to understand the relationship between man and nature, in order to understand the importance of ecosystem services provided by this plant group for the well-being of the population living in urban ecosystems.
