Environmental sex determination in a parasitic copepod: checking heterogeneity and unpredictability of the environment
For some organisms, sex is not fixed by genotype at conception but determined later by environmental conditions encountered during development (environmental sex determination, ESD). According to theoretical models, selection should favour ESD when the environment experienced by offspring is patchy and unpredictable and affects the relative fitness of males and females differentially. In a fiel...
متن کاملLarval density and the Charnov–Bull model of adaptive environmental sex determination in a copepod
Charnov and Bull suggested that environmentally induced variation in adult body size coupled with sexspecific differences in fitness can select for the evolution of adaptive environmental sex determination (ESD). In this study we determine whether larval density affects sex determination in the copepod Tigriopus californicus (Baker, 1912), as predicted by Charnov and Bull. Individuals reared at...
متن کاملEnvironmental sex determination in reptiles
In recent years, representatives of more than 40 families of reptiles have been studied to understand how environmental parameters affect sex determination. In this review, we summarise the distribution and taxonomic pattern of sex determining mechanisms, outline the main hypotheses of the adaptive significance of temperature sex determination (TSD), and of skewed population sex ratios. We also...

Mode and tempo in environmental sex determination in vertebrates.
One of the more colorful areas for scientific research, bound to apture the imagination of audiences inside and outside of science like, is sex. The difference between sexes defines much of human ndeavor; althoughour society nowstrives for equality of the sexes, iology has never treated them as equivalent, and most biological esearch focuses onmale and femaledifferences. Sexdetermination s one ...
