The sex ratio of alligators and crocodiles is strongly biased towards females, often as high as 10 females to 1 male. Skewed sex ratios (that is, ratios other than 1:1) are commonly found in species exhibiting environmental sex determination. In crocodilians the temperature of egg incubation is the environmental factor determining sex. If the temperature is cool, around 30 °C, the hatchlings are all female. Warmer temperatures, around 34 °C, hatch all males. The probability that any particular… Expand

Figures from this paper

Sex ratios of American alligators (Crocodylidae): male or female biased?
TLDR
It is concluded that there is no evidence at present of female-biased sex ratios in the juvenile and/or adult alligator populations, and consequently, that certain models of temperature-dependent sex determination in reptiles require reevaluation. Expand
Are Crocodilian Sex Ratios Female Biased? The Data Are Equivocal
TLDR
It is suggested that sex ratios of wild crocodilian populations are skewed toward females, and Woodward and Murray (1993) constructed a life-history model that incorporates this unusual predominance of females. Expand
Breeding Sex Ratios in Adult Leatherback Turtles (Dermochelys coriacea) May Compensate for Female-Biased Hatchling Sex Ratios
TLDR
It is demonstrated that there are as many actively breeding males as females in this population of leatherback turtles in St. Croix, USVI, indicating that mate choice or competition may play more of a role in sea turtle reproduction than previously thought. Expand
Environmental effects on fitness and consequences for sex allocation in a reptile with environmental sex determination
TLDR
It is found that developmental environments producing males were poorest for survival, growth and performance, suggesting that the sex ratio of G. ouachitensis should be male-biased, and that environmental effects on fitness will not explain the general tendency to skewed sex ratios. Expand
Effects of climatic conditions on sex ratios in nests of broad‐snouted caiman
TLDR
In the hypothetic scenarios of global warming, the effects of climatic conditions on sex ratios produced by caimans in wild nests and in particular how climate variables affect nest temperature and the percentage of females produced are examined. Expand
Genetic contribution to sex determination in turtles with environmental sex determination
TLDR
It appears that sex determination can be viewed as genotypic and monogenic with some individuals sexually inverted by the action of temperature. Expand
Effects of temperature variation on TSD in turtle (C. picta) populations
TLDR
A two-sex model of temperature-dependent sex determination (TSD) for a freshwater turtle population is formulated to understand how environmental temperature variations and nest heat conduction properties affect the long term dynamics of the population and may buffer projected negative effects on a population. Expand
Effects of density dependent sex allocation on the dynamics of a simultaneous hermaphroditic population: modelling and analysis.
TLDR
This work considers that the fractions of immature individuals acquiring male and female sexual roles are density dependent through nonlinear functions of a weighted total population size, and turns out to be a nonlinear discrete model. Expand
A mathematical model of a crocodilian population using delay-differential equations
TLDR
This work develops delay-differential equation (DDE) models describing the evolution of a crocodilian population and finds an equilibrium point and proves its local asymptotic stability in the single-delay model. Expand
A computational study of the effects of temperature variation on turtle egg development, sex determination, and population dynamics
TLDR
This dissertation develops a computational model that connects daily ambient air temperature and solar radiation readings to the sex of the turtles in the nests and to the male/female population structure and shows that an increase in temperature or variance may cause a decline in the population, but an increases in both temperature and variance produces the greatest decline.

The mechanism of temperature dependent sex determination in crocodilians: a hypothesis
TLDR
The hypothesis is used to explain the late temperature sensitive periods defined by high to low temperature shift experiments, why cooler temperatures are more effective at determining sex, how intermediate temperatures can produce both sexes, and geographical similarities in the pattern of TSD within crocodilians despite differing climates. Expand
Optimal sex ratio as a function of EGG incubation temperature in the crocodilians.
TLDR
The general pattern of TSD in crocodilians (female-male-female with female biased overall sex ratio) agrees well with the theory, but details of the pattern are problematic. Expand
Temperature of egg incubation determines sex in Alligator mississippiensis
TLDR
Sex is fully determined at the time of hatching and naturally irreversible thereafter, and depends on the temperature of egg incubation, which constitutes a possible selective evolutionary advantage of temperature-dependent sex determination (TSD) in alligators in that females become large and sexually mature as early as possible.

TLDR
The phylogenetic implications of TSD for crocodilians, and reptiles in particular, are related to the life history of the animal from conception to sexual maturity, and those animals that develop under optimal conditions grow fastest and largest and become male. Expand
On the Variability of Alligator Sex Ratios
TLDR
It is hypothesized that environmentally associated variation in age at sexual maturity of females produces sufficient variation in relative fitness of females to result in selection for low sex ratios during periods of resource abundance. Expand
When is sex environmentally determined?
TLDR
It is proposed that labile sex determination (not fixed at conception) is favoured by natural selection when an individual's fitness (as a male or female) is strongly influenced by environmental conditions and where the individual has little control over which environment it will experience. Expand
Life-History Tactics: A Review of the Ideas
  • S. Stearns

  • 1976
TLDR
This review organizes ideas on the evolution of life histories into more comprehensive theory that makes more readily falsifiable predictions, and examination of different definitions of fitness. Expand
Size-dependent pigmentation-pattern formation in embryos of Alligator mississippiensis: time of initiation of pattern generation mechanism
TLDR
It is shown how length at pattern formation is the prime factor in determining stripe number and how the pattern can be formed in the observed anterior–posterior sequence and numerical simulations are presented and show that the qualitative behaviour is consistent with the experimental results. Expand
Alligator Nesting in North-Central Florida
TLDR
The structure and development of the bony skull of Acipenser ruthenus and the structure of the dermal ethmoid shield of Osteolepis are studied. Expand
Age- and density-dependent population dynamics in static and variable environments.
TLDR
It is concluded that resonance due specifically to single-species age-structure effects will only be of practical importance in populations whose members have a life cycle consisting of a long immature phase followed by a short burst of intense reproductive effort. Expand
