Acesso em:.https://repositorio.ufpa.br/handle/2011/10632The objective of this work was to better comprehend the correlation between the meteorologic variables, solar radiation soil diffuse incident, the air temperature, relative humidity, and the precipitation in the subcanopy of the lowland forest in enviromental protection – Combu Island, in function of the natural regeneration of the forest, through the analysis of survival, mortality and birth in acai berry seedlings, species (Euterpe oleracea Mart.), between April 2010 and January 2011. An automatic meteorologic station was installed on the Combu Island that continually collected and registered the meteorologic data, producing hourly averages for each variable. Six plots were demarcated on the perimeter of the station, where one thousand sevent two acai berry seedlings were indentified and monitored. The number of living, dead, and new seedlings was monitored every two weeks. After integrating the biological data, they were correlated with the meteorological variables, and it was found that the precipitation and relative air humidity were the factors that best correlated with the survival of the seedlings with a value of .74 and .68, respectively. followed by the solar radiation soil diffuse incident in the subcanopy of the lowland, whose correlation was .42. The entry of solar radiation upwards of an average 391 W/m² (average for the observation period) suggests the determination of the higher death idexes of acai berry seedlings in the months of may and july, due to the absence of cloud cover and the lack of precipitation. Analyzing the entry of new seedlings was intially inhibited due to the rain and elevated relative air humidity in the months of April and May. After this period, there was a decrease in average rainfall and in humidity, thus providing ideal conditions for germination, probably potentiated by the elevation of solar radiation. Throughout the study period it was noted that same influence in the El Niño the natural regeneration of acai in the lowlands of Combu had the highest conservation of the population ocurred after the first part of June, with 71% survival, 29% death, compensated by 36% birth.Acesso AbertoAçaíPrecipitação (Meteorologia)Ilha do Combu - PAAmazônia brasileiraAnálise meteorológica no estabelecimento de plântulas do açaizeiro (Euterpe oleracea Mart.), na APA ilha do Combu, Belém, Pará, BrasilDissertaçãoCNPQ::CIENCIAS EXATAS E DA TERRA::GEOCIENCIASFÍSICA DO CLIMA
