Melanopsin and rod–cone photoreceptive systems account for all major accessory visual functions in mice
TLDR
The rod–cone and melanopsin systems together seem to provide all of the photic input for these accessory visual functions such as pupillary light reflex and circadian photo-entrainment. Expand

TLDR
The origin and definition of terminology (positive and negative masking, paradoxical masking), methods of quantifying masking and how masking is scored can greatly influence the interpretation of results are discussed. Expand
Transitional range of temperature, pivotal temperatures and thermosensitive stages for sex determination in reptiles
TLDR
Using terminology and definitions that accomodate interactions between genetic and environmental effects on sexual differentiation, and variability within populations for describing these relationships are offered. Expand
Pivotal temperatures for loggerhead turtles (Caretta caretta) from northern and southern nesting beaches
The pivotal incubation temperature (that giving 50% of each sex) was estimated for two clutches of eggs from loggerhead sea turtles (Caretta caretta) nesting in each of three areas along the east c...
LOCOMOTOR ACTIVITY AND NON‐PHOTIC INFLUENCES ON CIRCADIAN CLOCKS

  • 1 August 1996
TLDR
This review concludes that the circadian system does more than synchronize free-running rhythms to the solar day, and its non-photic functions and their interactions with photic inputs probably account for some of the anatomical complexity of circadian circuitry. Expand
Sex ratios of sea turtles
TLDR
Seasonal sex production profiles (SSPPs) show how similar overall sex ratios can be achieved in dissimilar ways. Expand
Estimating sex ratios of loggerhead turtles in Brazil from pivotal incubation durations
TLDR
The strongly female-biased sex ratio in Brazil is similar to that found previously for loggerheads using beaches in the eastern U.S.A. and suggests that a female- biased hatchling sex ratio may be a feature of loggerhead populations. Expand
Rapid down-regulation of mammalian period genes during behavioral resetting of the circadian clock.
TLDR
Circadian oscillations of Per1 and Per2 in the SCN of the Syrian hamster are described, showing that PER1 protein and mRNA cycles again behave in a manner consistent with a negative-feedback oscillator, and it is demonstrated that nonphotic resetting has the opposite effect to light: acutely down-regulating these genes. Expand
Critical periods and pivotal temperatures for sexual differentiation in loggerhead sea turtles
TLDR
Definition of the critical period in sea turtles should prove useful both in further work on the theoretical aspects of the phenomenon and in conservation programmes for sea turtles. Expand
SEXUAL DIFFERENTIATION IN HATCHLING LOGGERHEADS (CARETTA CARETTA) INCUBATED AT DIFFERENT CONTROLLED TEMPERATURES
A clutch of Caretta caretta eggs was divided into subgroups and incubated at constant temperatures ranging from 22?-36?C in 2? steps. Hatching occurred at 26?-34?C. At 30?C both males and femalesExpand
