          Abstract

          Studies on lower attines are scarce, especially on nesting and foraging ecology and behavior. This study aimed to contribute to the knowledge of an Attini in dunes ecosystems through the description of density and spatial distribution of Mycetophylax simplex (Emery, 1887) nests in a strip of mobile dunes in the Praia Grande beach, Torres, northern coast of Rio Grande do Sul, Brazil. The density and spatial distribution of nests were estimated in four plots of 2,500 m² each, in which were found 20, 209, 284 and 324 nests, with average densities of 0.01 nests/m², 0.09, 0.11 and 0.13 nests/m², respectively. The nests were found near to the vegetation and showed clumped distribution. The density and distribution pattern of the nests seem to be related to the availability of nesting places and foraging resources.

          Estudos sobre as atinis inferiores são escassos, principalmente em relação ao comportamento e ecologia da nidificação e do forrageamento. Este estudo objetivou contribuir ao conhecimento da tribo Attini em ecossistemas de dunas, através da descrição da densidade e da distribuição espacial dos ninhos de Mycetophylax simplex (Emery, 1887) em uma faixa de dunas móveis na praia Grande, município de Torres, litoral norte do Rio Grande do Sul. A densidade e distribuição espacial dos ninhos foram estimadas em quatro parcelas de 2.500 m² cada, nas quais foram encontrados 20, 209, 284 e 324 ninhos, com densidades médias, de 0,01 ninhos/m², 0,09, 0,11 e 0,13 ninhos/m², respectivamente. Os ninhos encontravam-se próximos à vegetação e com distribuição agregada. É sugerido que a densidade e o padrão de distribuição dos ninhos estariam relacionados à disponibilidade de locais de nidificação e à presença de recursos para forrageamento.
