Framework for modelling hatching sex ratios, showing the relationships between the microclimate and physiological models. The occurrence of intersexuality in harpacticoid copepods and its relationship with pollution. Sex determination mechanisms produce the sex ratio, a key demographic parameter crucial for population viability.

Though sex change has been proposed for only a few copepod species, intersexuality is widespread. Related articles in Web of Science Google Scholar. Sex determination and differentiation. This hypothesis has not yet been proven, but some studies have shown that the sex ratio of Calanus spp.

Thus, for any given species to have TSD, it should fulfill both of the following two conditions: 1 not having sex chromosomes, and 2 have sex ratio response to temperature within the RTD Fig.
In addition, the observed sex ratio response to temperature, especially in the Southern flounder, partly occurs outside the RTD, thus not being representative of true TSD. Further, species with TSD exhibit only one general sex ratio response pattern to temperature.
Figure 3. After this period, however, sex reversal is impossible. Sex determination and differentiation. Our data suggest that A.
