However, considering only the ovigerous females, the correlation with the burrow temperature was considered strong and significant.

Journal of Experimental Marine Biology and Ecology1: Callianassidae in northern Chile. The sex ratio observed in our study corroborates these studies. According to Hill and Posey najor, salinity can exert a strong effect in the population of callianassids, due to its seasonal variations.

Spinodae e Callichirus major Say Crustacea: The recruitment of the species occurs in almost the entire study period, but it is intensified right after the reproductive peak, due to vallichirus short larval development of this species. The seasonal variations of juveniles in a population are natural for callianassids, due to predation, environmental and biogeographic factors acting on the larval phases Rodrigues, After spawning, the larvae usually undergo a series of molts in the open sea and then return mwjor the coast to settle.

Positive correlations mean that the parameters are related to an increase in the animal abundance, while negative correlations, cause the decrease in the animal abundance. A Student t test was applied to compare the value of abiotic factors between the dry and rainy seasons. The frequency of ovigerous females Fig.
