dc.description.abstract | Neotropical savannas are seasonal ecosystems that occur in the Americas and are
denominated Cerrado in Brazil. It presents phytophysiognomies distinguished by the
size of the individuals, especially the Rupestrian fields that occur in areas of high
altitude (> 900 meters). For this study, two areas were chosen as models: the campo
sujo at 1.400 meters of altitude on the top of the Rupestrian field (CSRF), and the
typical and continuous campo sujo (TCS) at the base of the Rupestrian field, at 700
meters of altitude. These areas were selected to evaluate the plant responses related to
three parameters: altitude, leaf phenology and seasonality. The phenology, plant
anatomy and physiology data were obtained using Byrsonima verbascifolia, Roupala
montana and Solanum lycocarpum. These taxa were selected based on the occurrence in
the model areas, the satisfactory sample size and to fit into two leaf phenology:
evergreen (R. montana and S. lycocarpum) and brevideciduous (B. verbascifolia). The
abiotic data found for the dry campo sujo on Rupestrian fields show a less stressful
habitat than what was expected, with leaf morphophysiological plasticity in response to
abiotic factors, such as humidity, temperature and wind. A few physiological
differences were found between areas, which may reflect the high anatomical
modifications. The species of the same leaf phenology did not present the same
physiological behavior in dry and wet seasons, being contrary to the initial hypothesis. | |
