Spatial distribution of Hyalella patagonica Cunningham, 1871 (Amphipoda) on Andean Patagonian river (Truful-Truful river, 38°S, Araucania region, Chile)
The amphipod Hyalella patagonica is widespread in Andean inland waters in Argentinean and Chilean Patagonia, this species inhabits in littoral zones of rivers, streams, lakes and lagoons, that have mainly aggregated patterns of spatial distribution in according to the literature. The aim of the present study is to apply different kinds of aggregation models for explain spatial distribution of H. patagonica collected in a North Andean Patagonian stream. It was applied different kind of dispersion coefficient for understand H. patagonica spatial pattern. The results revealed that H. patagonica population have aggregated distribution, but not necessary negative binomial distribution that is frequent probabilistic model associated to aggregated spatial distribution. The results would be similar to patterns observed for Hyalella genus in Patagonian inland waters.
