Predator efficiency is a sensitive tool for the analisis of the temporal extension of human occupations in a certain landscapes. The use of an economic ranking based on prey size -but which contemplates the general offering of resources and their etoecological aspects -was of great utility for contrasting the hypothesis of a brief and sporadic occupation of the north patagonian forest with models that postulate the presence of human adaptations to these environments. The indexes that contrast the relative frequencies of species with its corporal size as proxy data to estimate predator efficiency determine as a result that it is low in the Meliquina Archaeological Locality. The highest NISP corresponds to species that have very low economic yield, but are highly predictable and abundant, such as mollusks, fish, rodents and waterfowl. The species of greatest yield, such as cervids and carnivores are, in general, solitary, have large territories, are largely crepuscular/ nocturnal, elusive, and have a propensity to be over-exploited at the local level. The economy including a broad spectrum of resources is reflected here as a process destined to increase the productivity of the area, but at the expense of a decrease in the predator efficiency. This would be in agreement with our expectations for stable and recurring occupations, or at least more prolonged ones in the area.
El otro agente aquí analizado en relación con la formación de las concentraciones de huesos es el agua (Behrensmeyer 1975; Hanson 1980; Voorhies 1969). Para evaluar su incidencia sobre las acumulaciones de NM1, se comparó la representación de partes esqueletarias en el sitio con un modelo de selección y transporte de partes producido por el agua en un contexto experimental. A su vez, se midieron las orientaciones de los huesos largos sobre las plantas de todas las cuadrículas confeccionadas durante la excavación.
