Variation of the rainfall regime in the Northern region and its effect on the Odonata (Insecta) in Been river, Amazonas, Brazil
The goal of this work was to know the effect of precipitation in four periods (Rising, Flood, Lowing and Dry) on Odonata larvae living near to the macrophyte Salvinia auriculata Aubl., in Been River, Amazonas, Brazil. The biological material was collected in the Been river in the section near the ri...

| description | The goal of this work was to know the effect of precipitation in four periods (Rising, Flood, Lowing and Dry) on Odonata larvae living near to the macrophyte Salvinia auriculata Aubl., in Been River, Amazonas, Brazil. The biological material was collected in the Been river in the section near the river Madeira, state of Amazonas, Brazil. Sampling was conducted in stands of three macrophytes S. auriculata in four periods: rising (November 2012), flood (February 2013), lowing (May 2013), and dry (August 2013). A total of 286 Odonata larvae were identified in the river studied. Six families and 14 genera were identified. The flood period showed the highest abundance in the studied period. Acanthagrion presented a positive correlation with flood period in axis 1 and Telebasis also positive, but in the dry period. In conclusion, although there are few studies on Odonata larvae associated with floating macrophytes in the Amazon, the results of this work showed the importance of knowing the distribution of larval abundance throughout the year. Flood and dry period showed to be the period with the highest abundance of Odonata genera. In addition, the principal component analysis showed that some species are more sensitive to the periods of the year, Telebasis in the dry period and Acanthagrion in the flood period. |

El objetivo de este trabajo fue conocer el efecto de la precipitación en cuatro períodos (aumento, inundación, baja y sequía) en las larvas de Odonata que viven cerca del macrófito Salvinia auriculata Aubl., en el río Been, Amazonas, Brasil. El material biológico se recolectó en el río Been en la sección cerca del río Madeira, estado de Amazonas, Brasil. El muestreo se realizó en rodales de tres macrófitos en cuatro períodos: en aumento (noviembre de 2012), inundación (febrero de 2013), baja (mayo de 2013) y Seca (agosto de 2013). Se identificaron un total de 286 larvas de Odonata en el río estudiado. Se identificaron seis familias y 14 géneros. El período de inundación mostró la mayor densidad en el período estudiado. Acanthagrion presentó una correlación positiva con el período de inundación en el eje 1 y Telebasis también positivo, pero en el período seco. En conclusión, aunque hay pocos estudios sobre larvas de Odonata asociadas con macrófitos flotantes en la Amazonia, los resultados de este trabajo mostraron la importancia de conocer la distribución de la densidad larvaria a lo largo del año. El período de inundación y seco mostró ser el período con la mayor densidad de los géneros Odonata. Además, el análisis de componentes principales mostró que algunas especies son más sensibles a los períodos del año, Telebasis en el período seco y Acanthagrion en el período de inundación.
