Time keeping by the quail's eye: Cireadian regulation of melatonin production
GENERAL AND COMPARATIVE ENDOCRINOLOGY, 145(3), 232–236.
author keywords: circadian pacemaker; retina; Coturnix; serotonin
MeSH headings : 5-Hydroxytryptophan / pharmacology; Animals; Biological Clocks / physiology; Circadian Rhythm / physiology; Coturnix / physiology; Darkness; Eye / drug effects; Eye / metabolism; Eye / radiation effects; Light; Male; Melatonin / metabolism; Retina / drug effects; Retina / metabolism; Retina / radiation effects; Serotonin / pharmacology; Time Factors; Tissue Culture Techniques
TL;DR:
The results show definitively that the eyes are the loci of a biological clock and strengthen the hypothesis that the ocular clock is a circadian pacemaker that can affect the rest of the circadian system via the cyclic synthesis and release of melatonin.

2003 journal article
Ocular clocks are tightly coupled and act as pacemakers in the circadian system of Japanese quail
AMERICAN JOURNAL OF PHYSIOLOGY-REGULATORY INTEGRATIVE AND COMPARATIVE PHYSIOLOGY, 284(1), R208–R218.
author keywords: melatonin; body temperature; eye; circadian; Coturnix
MeSH headings : Animals; Biological Clocks / physiology; Body Temperature; Circadian Rhythm / physiology; Coturnix / physiology; Eye / chemistry; Female; Male; Melatonin / analysis; Melatonin / blood; Ocular Physiological Phenomena; Photoperiod
TL;DR:
The ability to maintain phase in DD and rapidly recouple after out-of-phase entrainment demonstrates that the eyes are strongly coupled pacemakers that work in synchrony to drive circadian rhythmicity in Japanese quail.

Pineal melatonin secretion, but not ocular melatonin secretion, is sufficient to maintain normal immune responses in Japanese quail (Coturnix coturnix japonica)
GENERAL AND COMPARATIVE ENDOCRINOLOGY, 126(3), 352–358.
author keywords: melatonin; immune response; Japanese quail; pineal; eye
MeSH headings : Animals; Antibody Formation; CD4 Lymphocyte Count; CD8-Positive T-Lymphocytes; Coturnix / immunology; Coturnix / physiology; Eye / metabolism; Female; Flow Cytometry; Immunity; Immunity, Cellular; Lymphocyte Count; Melatonin / administration & dosage; Melatonin / metabolism; Pineal Gland / metabolism; Pineal Gland / surgery
TL;DR:
The data suggest that immunodepression is only observed in birds with two thirds of the plasma melatonin removed by pinealectomy, and removal of one third of the Plasma melatonin is not sufficient to reduce cellular and humoral responses in the Japanese quail.

2001 chapter
Circadian organization in nonmammalian vertebrates
In N. T. A. E. M. Blass & F. King (Eds.), Handbook of behavioral neurobiology (pp. 111–140).
Ed(s): N. E. M. Blass & F. King
TL;DR:
A surprising complexity in the organization of circadian systems in nonmammalian vertebrates is revealed, with at least three sites shown to exhibit autonomous circadian rhythmicity: the pineal organ, the suprachiasmatic area of the hypothalamus, and the eyes.

Circadian ovulatory rhythms in Japanese quail: Role of ocular and extraocular pacemakers
JOURNAL OF BIOLOGICAL RHYTHMS, 15(2), 172–183.
author keywords: Japanese quail; circadian; ovulation; internal coincidence; retina; extraretinal photoreception
MeSH headings : Animals; Blindness / physiopathology; Body Temperature; Circadian Rhythm / physiology; Coturnix / physiology; Female; Ocular Physiological Phenomena; Oviposition; Ovulation / physiology; Photoperiod; Photoreceptor Cells, Vertebrate / physiology; Sensory Deprivation / physiology; Vision, Ocular / physiology
TL;DR:
The results do not show a role for ocular pacemakers in the control of ovulation, but they do support the hypotheses that entrainment of the central oscillators by extraretinally perceived light is sufficient to preserve a normal ovulatory pattern in LD in the absence of the ocularpacemakers.

TL;DR:
It was concluded that melatonin can affect both the expression of the activity rhythm as well as the circadian oscillator driving the activity rhythms of the green anole.

Dopamine mediates circadian rhythms of rod-cone dominance in the Japanese quail retina

MeSH headings : Adaptation, Ocular; Animals; Circadian Rhythm / physiology; Coturnix / physiology; Dihydroxyphenylalanine / metabolism; Electroretinography; Photoreceptor Cells, Vertebrate / physiology
TL;DR:
It is suggested that dopamine, under the control of a circadian oscillator, has a key role in modulating sensitivity and rod–cone dominance in the Japanese quail retina.

Effects of fasting on the circadian body temperature rhythm of Japanese quail
PHYSIOLOGY & BEHAVIOR, 66(1), 137–143.
author keywords: circadian; temperature rhythm; fasting; activity rhythm; quail
MeSH headings : Animals; Blindness / physiopathology; Body Temperature / physiology; Circadian Rhythm / physiology; Coturnix / physiology; Fasting / physiology; Female; Photoreceptor Cells / physiology
TL;DR:
Measurements of activity levels before and during fasting indicate that fasting-induced hypothermia cannot be explained simply as a consequence of decreases in activity levels, and food deprivation was also observed to cause significant phase shifts in the endogenous rhythm of body temperature.

Formal properties of the circadian and photoperiodic systems of Japanese quail: Phase response curve and effects of T-cycles
JOURNAL OF BIOLOGICAL RHYTHMS, 14(5), 378–390.
author keywords: Japanese quail; circadian rhythms; photoperiodism; reproduction; phase response curve; T-cycles
MeSH headings : Animals; Body Temperature / physiology; Circadian Rhythm / physiology; Coturnix / physiology; Female; Motor Activity / physiology; Oviposition / physiology; Ovulation / physiology; Photoperiod; Time Factors
TL;DR:
Studies of the circadian and photoperiodic system of Japanese quail showed that the circadian system acts like a low-amplitude oscillator: It is readily reset by light without significant transients, has a Type 0 phase response curve (PRC), and has a large range of entrainment.

Eye and gonad: Role in the dual-oscillator circadian system of female Japanese quail
AMERICAN JOURNAL OF PHYSIOLOGY-REGULATORY INTEGRATIVE AND COMPARATIVE PHYSIOLOGY, 272(1), R172–R182.

MeSH headings : Animals; Body Temperature / physiology; Circadian Rhythm; Coturnix / physiology; Female; Ocular Physiological Phenomena; Ovariectomy; Ovary / physiology; Oviposition / physiology; Photoperiod; Sensory Deprivation
TL;DR:
The two free-running oscillators in eye-patched birds showed evidence of mutual interaction, and significantly, the phase relationships that occur as the two oscillators interact can determine whether or not ovulation occurs.

TL;DR:
The blood melatonin rhythm precisely reflected the rhythms shown by the pineal and eyes, supporting the idea that the blood rhythm is a result of melatonin secretion by both the eyes and pineal.

PHOTOPERIODIC TIME MEASUREMENT IN THE MALE DEER MOUSE, PEROMYSCUS-MANICULATUS

MeSH headings : Activity Cycles / radiation effects; Animals; Circadian Rhythm / radiation effects; Light; Male; Organ Size / radiation effects; Periodicity; Peromyscus / growth & development; Seminal Vesicles / growth & development; Testis / growth & development; Weaning
TL;DR:
It is demonstrated that light falling during the animal's subjective night, from activity onset to at least 11.8 h after activity onset, stimulates growth and maturation of the reproductive system, whereas light fell during the rest of the circadian cycle is nonstimulatory.
