Phenology of five plant species with potential for fruit resources in the Pantanal ; Fenologia de cinco espécies de plantas com potencial para recursos de frutos no Pantanal

The phenology of plant species is directly reflected by the environmental conditions, which benefits a straight relationship between fish and fruit, for instance. The present study relates the phenology of five plant species at an ecological station in the Pantanal regarding the rainfall and different flooding seasons. The study was conducted in the Paraguay river in the Northern Pantanal, following an entire hidrologic cycle of full and dry. A positive correlation was found for the species Spondias mombin, Inga vera, Bactris riparia, and Bactris brongniartii with flooding, in which unripe fruits occurred at the beginning of the rainy season and ripe fruits occurred at high water. On the other hand, the production of unripe fruits of Erythrina fusca species was negatively correlated with the water table level, with the flowering, and fruiting occurring during the dry period. The fruiting period of the species S. mombin, I. vera, B. riparia, and B. brongniartii can benefit ichthyofauna which consume its fruits and seeds during the wet season, whereas E. fusca contributes to the dry season. There is a need to further the knowledge of plant phenology in the Pantanal and this information must be taken into account in conservation units for management. ; A fenologia das espécies vegetais reflete-se diretamente nas condições ambientais, o que favorece uma relação direta entre peixes e frutos, por exemplo. O presente estudo relaciona a fenologia de cinco espécies vegetais em uma estação ecológica no Pantanal quanto à pluviosidade e diferentes épocas de cheias. O estudo foi realizado no rio Paraguai no Pantanal Norte, seguindo todo um ciclo hidrológico de cheia e seca. Foi encontrada correlação positiva para as espécies Spondias mombin, Inga vera, Bactris riparia e Bactris brongniartii com a inundação, em que os frutos verdes ocorreram no início da estação chuvosa e os frutos maduros ocorreram na cheia. Por outro lado, a produção de frutos verdes da espécie Erythrina fusca correlacionou-se negativamente com o nível do ...
