Can dung beetles (Scarabaeinae) indicate the status of Amazonia’s ecosystems? Insights integrating anthropogenic disturbance with seasonal patterns

Temporal and spatial variation in dung beetles abundances is a pattern observed in many tropical forests. The present study evaluated the seasonal patterns of dung beetles in a range of increasingly disturbed ecosystems of the state of Para, northern Brazil, to identify valuable disturbance indicators. The areas included native forest, agriculture, pasture for extensive livestock grazing and secondary forests. Fieldwork was carried out encompassing the complete range of environmental conditions encountered during the year. In total, 13,649 individuals were captured within 23 genera and 99 species but with pronounced differences among ecosystems and seasons. The obtained results seem to demonstrate that dung beetles can be used to help identify ecosystems under very complex and variable environmental conditions. The ecological drift observed also demonstrates the possibility of using dung beetles as ecological indicators of disturbance in Amazonia.

PERFIL DOS COMERCIANTES DE PLANTAS MEDICINAIS NO MUNICÍPIO DE URUARÁ, PARÁ, BRASIL

The present study had as objective to analyze the socioeconomic profile of merchants of products and medicinal plants of the urban area of the municipality of Uruará, Pará. For this purpose, semi-structured interviews were conducted with all existing merchants in the urban area of the municipality. As a result, it was found that
