Dump size and distance from the nest define the investment in waste management in Sericomyrmex mayri (Formicidae: Myrmicinae: Attini)
The farming system practiced by non-leaf-cutting ants Sericomyrmex mayri (Formicidae: Myrmicinae: Attini) involves a mutualistic interaction with symbiotic fungi. Their colonies’ success depends on several factors, such as the fungus garden protection against pathogens. Garden contamination may depend on the aspects involved in waste management. However, specific local conditions, including nest and dump sizes, nest-dump distances and abiotic conditions are relevant and overlooked, especially for non-leaf-cutting ants. We aimed to explore the natural history involved in Sericomyrmex mayri waste management. Hence, we documented the relationships between 1) the foraging rate and waste removal activities with dump size, 2) the size of refuse dumps and their distance from nest entrances, and 3) the foraging activity and the rate of waste disposal with climatic conditions. The study was developed in the Atlantic Forest, Southeastern Brazil, wherein 33 colonies’ activities were monitored for three consecutive days, during different day-periods. More prominent dumps received less waste and were located at further distances from the nest. Additionally, daily temperature and humidity positively influenced waste disposal and foraging activities, respectively. These findings provide information on how dump size and distance from the nest may define the investment of waste management of non-leaf-cutting ants.

El sistema de cultivo que practican las hormigas no cortadoras de hojas Sericomyrmex mayri (Formicidae: Myrmicinae: Attini) incluye una interacción mutualística con hongos simbióticos. El éxito de sus colonias depende de varios factores, como, por ejemplo, la protección del jardín del hongo contra los microorganismos patógenos, lo cual es clave debido a la naturaleza obligatoria de esta asociación. Se sabe que la contaminación del jardín del hongo se relaciona con el manejo de los residuos por parte de las obreras. Por lo tanto, nuestro objetivo fue investigar la historia natural de la gestión de residuos en Sericomyrmex mayri. Para esto, documentamos las relaciones entre 1) las actividades de recolección de residuos y forrajeo con el tamaño del basureros, 2) el tamaño de los basureros y su distancia de las entradas de los nidos, y 3) la actividad de forrajeo y la tasa de eliminación de residuos con las condiciones climáticas. El estudio se desarrolló en el Bosque Atlántico, al sudeste de Brasil, donde se monitoreó la actividad de 33 colonias durante tres días consecutivos, en diferentes momentos del día. Los basureros más grandes recibieron menos residuos y se encontraron a distancias mayores del nido. Además, la temperatura y la humedad diarias influyeron de manera positiva en la eliminación de residuos y las actividades de forrajeo, respectivamente. Estos hallazgos aportan información sobre cómo el tamaño del basurero y la distancia desde el nido pueden definir la inversión en el manejo de desechos de hormigas no-cortadoras de hojas.
