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.

This study creates a baseline for further research with C. ABSTRACT The aim of this paper was to study the population ecology of Callichirus major Say, at Piedade Beach, State of Pernambuco, Brazil, through the analysis of parameters such as sex ratio, reproductive period and recruitment callichkrus juveniles into this population.

Esta faixa foi dividida em cinco setores: In April and from July to Novemberno difference in the frequency of juveniles and adults was detected. In this study, the mmajor abundance of C. In this study, the highest frequency of ovigerous females was observed in the dry period equatorial summer – September and February Fig.

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.


Laboratory procedures At the laboratory, the individuals were identified and sexed according to Melo The air and burrow temperatures varied significantly between the dry and rainy periods, with the highest values in the dry period. The callidhirus development of C.

However, they observed monthly oscillations in the sex ratio; the females were more abundant from September to February and the males, from March to September, and in this study, the females were more abundant in March, with ovigerous females in March and November, and males more abundant mwjor August, October, February and May.

The determination of the reproductive period was based on the monthly percentages of ovigerous females Vazzoler, This paper creates a baseline for further researches on C.
