Through environmental sex determination (ESD), offspring become male or female in response to an environmental factor or factors during development. Examples are known to occur in fish (Conover and Heins 1987), reptiles (Bull 1980), nematodes (Petersen 1972), and shrimp (Adams et al. 1987) (general ESD review in Adams et al. 1987). Current theory for the evolution of ESD suggests that it is favored over genotypic sex determination when the environment is patchy with respect to developmental… Expand
Adaptive significance of environmental sex determination in an amphipod
TLDR
The relationship between size and fitness for both males and females, in a population of G. duebeni, an amphipod known to have ESD, was investigated, and the adaptive explanation for the evolution and maintenance of ESD in this species was supported. Expand
Environmental sex determination in a parasitic copepod: checking heterogeneity and unpredictability of the environment
TLDR
The environmental heterogeneity displayed among individuals of the sea squirt Ciona intestinalis, a host for the copepod Pachypygus gibber, which is characterised by ESD, is analysed to support the adaptive nature of ESD in P. gibber. Expand
Larval density and the Charnov–Bull model of adaptive environmental sex determination in a copepod
TLDR
Whether larval density affects sex determination in the copepod Tigriopus californicus is determined and sex-specific estimates of selection on adult body size will inform future models of adaptive ESD in this species and other copepods. Expand
VARIATION IN ENVIRONMENTAL AND GENOTYPIC SEX‐DETERMINING MECHANISMS ACROSS A LATITUDINAL GRADIENT IN THE FISH, MENIDIA MENIDIA
TLDR
It is suggested that sex determination in M. menidia is controlled by an interaction between major genetic factors, polygenic factors, and temperature and that the relative importance of each component differs with latitude. Expand
SEX RATIO SELECTION AND THE EVOLUTION OF ENVIRONMENTAL SEX DETERMINATION IN LABORATORY POPULATIONS OF MENIDIA MENIDIA
TLDR
This model empirically modeled the evolution of environmental sex determination by maintaining five laboratory populations of a fish with temperature‐dependent sex determination in extreme constant temperature environments that caused highly skewed sex ratios to occur initially, demonstrating that ESD is capable of evolving in response to selection.

Fisher vs. the Worms: Extraordinary Sex Ratios in Nematodes and the Mechanisms that Produce Them
TLDR
Recent research in nematodes that has characterized the mechanisms underlying highly skewed sex ratios in fully diploid systems are discussed, including self-fertile hermaphroditism and the adaptive elimination of sperm competition factors, facultative parthenogenesis, non-Mendelian meiotic oddities involving the sex chromosomes, and environmental sex determination.

Sexual Development and the Environment: Conclusions from 40 Years of Theory
In this review, we consider the insight that has been gained through theoretical examination of environmental sex determination (ESD) and thermolability – how theory has progressed our understandingExpand
Temperature and photoperiod effects on sex determination in a fish
TLDR
This work has confirmed the first documented case of photoperiod-dependent sex determination in a gonochoristic vertebrate, the California grunion, and revealed that more females were produced at cooler temperatures and longer day lengths, which is consistent with female-biased sex ratios early in the breeding season. Expand
Environmental sex determination in a splash pool copepod
TLDR
The effect of temperature dependent sex determination (TSD) on the primary sex ratio of the harpacticoid copepod, Tigriopus californicus is investigated and it is suggested that the observed level of TSD is not an artefact of testing field-captured individuals in a novel laboratory environment.

TLDR
The effects of the gender × incubation temperature interaction on survivorship of hatchling turtles observed in the field experiment may have been mediated by temperature‐dependent antipredator behavior. Expand

Adaptive variation in environmental and genetic sex determination in a fish
TLDR
It is shown that in a fish with temperature-dependent sex determination, populations at different latitudes compensate for differences in thermal environment and seasonality by adjusting the response of sex ratio to temperature, and by altering the level of environmental as opposed to genetic control. Expand
Variation in sex determination in natural populations of a shrimp
TLDR
Strategies of sex determination were studied in Gammarus duebeni, a brackish water shrimp, showing that sex is determined several weeks after young are released by the mother; that the critical daylength is longer at Budle Bay than in Germany; and that thecritical response is cued at the onset of a photophase. Expand
Non-fisherian sex ratios with sex change and environmental sex determination
TLDR
A single model that applies to a wide range of SC and ESD biologies is generalized and the principle that emerges from this model appears to explain strong female and male excesses seen in sex-changing fish and invertebrates and in nematodes with ESD. Expand
Sex ratio evolution when fitness varies
TLDR
The sex ratio may coevolve with the offspring's choice of patch type and the environmental cue it uses in determining sex; when possible, embryos are selected to avoid patches detrimental to both sexes, and areselected to determine sex in response to the cue which indicates the greatest differential benefit to maleness versus femaleness. Expand
Facultative sex ratios and population dynamics
TLDR
It is shown that selection can favour genes which result in the temporary overproduction of one or the other sex, under certain general conditions. Expand
