Effect of the nests of Acromyrmex lobicornis (Formicidae: Myrmicinae) on the decomposition of litter, in the "Monte" desert

Decomposition is a fundamental process of ecosystems. In arid and semi-arid environments these processes slow down due to unfavorable climatic conditions for microbial activity so that organisms such as ants become key because in their nests they accumulate organic matter as a result of their foragi...

Decomposition is a fundamental process of ecosystems. In arid and semi-arid environments these processes slow down due to unfavorable climatic conditions for microbial activity so that organisms such as ants become key because in their nests they accumulate organic matter as a result of their foraging activities. Our objective was to evaluate the influence of the nests of Acromyrmex lobicornis on the decomposition process of the surrounding material. We buried 42 bags of litter in seven shrubs with nest and seven shrubs without nest (three bags per bush). At 21, 35 and 60 days, the bags were removed, cleaned, weighed, dried and calcined. The rate of decomposition in nests of A. lobicornis was significantly lower than that of soils without anthills. The marked seasonality in the desert of Monte and the sterilization of the nest could be some of the causes. La descomposición es un proceso fundamental de los ecosistemas. En ambientes áridos y semiáridos, estos procesos se ralentizan debido a las condiciones climáticas desfavorables para la actividad microbiana, por lo que, organismos como las hormigas se vuelven claves ya que en sus nidos acumulan materia orgánica como consecuencia de su actividad de forrajeo. Nuestro objetivo fue evaluar la influencia de los nidos de Acromyrmex lobicornis sobre el proceso de descomposición del material circundante. Se enterraron 42 bolsas de hojarasca en 7 arbustos con y sin hormiguero (tres bolsas por arbusto). A los 21, 35 y 60 días, las bolsas fueron retiradas, limpiadas, pesadas, secadas y calcinadas. La tasa de descomposición en nidos de A. lobicornis fue significativamente menor con respecto a la de suelos sin hormigueros. La marcada estacionalidad en el desierto del monte y la esterilización del nido podrían ser algunos de los causantes.
