Probabilistic model for understand presence of Temnocephala chilensis (Moquin-Tandom 1846) (Platyhelminthes: Temnocephalidae) on adults of a population of Parastacus pugnax (Poeppig 1835) (Decapoda: Parastacidae) in southern Chile [Modelo probabilistico para comprender la presencia de Temnocephala chilensis (Moquin-Tandom 1846) (Platyhelminthes: Temnocephalidae) en una población adulta de Parastacus pugnax (Poeppig 1835) (Decapoda: Parastacidae) en el sur de Chile]

Abstract
The literature reported ectocommensals associated to Parastacus pugnax (Poeppig, 1835), but there are not ecological studies about abundance of these on P. pugnax. The aim of the present study was to analyze the abundances of ectocommensal Temnocephala chilensis (Moquin-Tandom, 1846), on P.pugnax. It had not correlation between T. chilensis number with total length and total weight of P. pugnax. T. chilensis has an associated spatial distribution and negative binomial distribution. Ecological and evolutive topics were discussed.
