This paper reviews current knowledge of photoperiod control of GnRH-1 secretion and proposes a model in which two processes act together to regulate GnRH1 secretion. Photo-induction controls GnRH1 secretion and is directly related to prevailing photoperiod. Photo-inhibition, a longer term process, acts through GnRH1 synthesis. It progresses each day during daylight hours, but reverses during darkness. Thus, photo-inhibition gradually increases when photoperiods exceed 12h, and reverses under… Expand

TLDR
Results clearly indicate that tree sparrows are capable of fine discrimination of photoperiodic information and use day length for GnRH-I expression to control their seasonal reproduction. Expand
Manipulation of photoperiod perception advances gonadal growth but not laying date in the great tit
TLDR
The results indicate that photoperiod sensitivity is not constraining the advancement of laying date under current environmental conditions and suggest that evolution of sensitivity to other supplementary cues is necessary to advance reproduction under global warming. Expand
Photoperiodic regulation of reproduction in birds
TLDR
Hormones of the hypothalamus localised particularly in the paraventricular organ and lateral septal area of hypothalamus are implicated in regulation of photoperiod induced reproductive response and behaviour in seasonal breeding avian species. Expand
Both Low Temperature and Shorter Duration of Food Availability Delay Testicular Regression and Affect the Daily Cycle in Body Temperature in a Songbird

TLDR
Both lower temperature and food restriction delayed regression, as if thePhotoperiod was shorter than it actually was, and both resulted in daily cycles in body temperature that reflected cycles under shorter photoperiods, implying that the daily cycle in bodyTemperature is possibly a common pathway through which nonphotoperiodic cues may operate. Expand
Maternal photoperiodic programming enlightens the internal regulation of thyroid-hormone deiodinases in tanycytes.
TLDR
This review addresses MPP and discusses the latest findings on its impact on the thyrotrophin/deiodinase network, and a unifying scheme is suggested in which timing arises from a long-term communication between the pars tuberalis and the hypothalamus and resultant spontaneous changes in local thyroid hormone status, independently of the pineal melatonin signal.

The effect of food restriction on the regulation of gonadotropin-releasing hormone in male house finches (Haemorhous mexicanus).
Seasonal activation of the vertebrate hypothalamic-pituitary-gonadal (HPG) axis and gonadal development is initiated by gonadotropin-releasing hormone-I (GnRH) release from the hypothalamus. InExpand
Circadian rhythm in photoperiodic expressions of GnRH-I and GnIH regulating seasonal reproduction in the Eurasian tree sparrow, Passer montanus.
TLDR
The findings suggest that an endogenous circadian rhythm is involved in photoperiodic expressions of GnRH-I and GnIH in the hypothalamus controlling seasonal reproduction in the Eurasian tree sparrow and indicate a shift in their expressions depending upon whether the light falls in the photoinducible or non-photoinducibles phase of an endogenouscircadian rhythm.

Breeding Latitude and Annual Cycle Timing in a Songbird
TLDR
The hypothesis that migratory strategy and breeding latitude may predict differences in photoperiodic threshold for both migratory and reproductive timing is supported and contributes to the understanding of regulation of timing in annual cycles and improve predictions of how species might respond to changing environments. Expand
Maternal photoperiodic programming enlightens the internal regulation of thyroid‐hormone deiodinases in tanycytes
TLDR
This review addresses MPP and discusses the latest findings on its impact on the thyrotrophin/deiodinase network, and a unifying scheme is suggested in which timing arises from a long‐term communication between the pars tuberalis and the hypothalamus and resultant spontaneous changes in local thyroid hormone status, independently of the pineal melatonin signal. Expand
Changes in processes downstream of the hypothalamus are associated with seasonal follicle development in a songbird, the dark-eyed junco (Junco hyemalis).
TLDR
Differences in breeding-stage-specific patterns of pituitary and ovarian responsiveness in free-living female dark-eyed juncos are examined, suggesting seasonal variation in female's sensitivity to signals of HPG activity and energetic or stress signals. Expand

TLDR
There may be no difference between absolute and relative photorefractory species in how they utilise the annual cycle in photoperiod to time regression, but birds appear to be using more subtle cues from the pattern of change inPhotoperiod. Expand
Photoperiodic Control of Seasonality in Birds
This review examines how birds use the annual cycle in photoperiod to ensure that seasonal events—breeding, molt, and song production—happen at the appropriate time of year. Differences in breedingExpand
Seasonal regulation of reproduction: altered role of melatonin under naturalistic conditions in hamsters
TLDR
The seasonal transition to the summer photosensitive phenotype is triggered prior to the equinox without exposure to long days and is thereafter melatonin-independent, eliminating the requirement for long-day melatonin signalling. Expand
Circadian Control of Photoperiodism in the House Finch demonstrated by Interrupted-night Experiments
TLDR
The following experiments were designed to test the hypothesis of circadian control by exposing birds to non-stimulatory cycles of 24, 48, or 72 h with a main light period of 6 h during each cycle and interrupting the ensuing long dark periods with 1-h photoperiods. Expand
Timing of photorefractoriness in the European starling: significance of photoperiod early and late in the reproductive cycle.
TLDR
The data show that, in contrast to some other species of passerine birds, the onset of photorefractoriness does not become fixed before the testes have undergone considerable development, and that the photoperiodic conditions experienced at the end of the testicular growth phase are still effective in determining the precise time of onset.

TLDR
Results suggest that the physiological basis of refractoriness lies either in the neural circuits regulating neurohormone secretion or in the photoperiodic clock mechanism itself. Expand

It is demonstrated that light-induced Dio2 expression in the MBH may be involved in the photoperiodic response of gonads in Japanese quail. Expand

  • 2006
TLDR
The data show that birds are very sensitive to changes in photoperiod but that they do not simply respond to absolute photoperperiod nor can they rely on a circannual clock, instead, birds appear to respond to the shape of the annual change inPhotoperiod. Expand

TLDR
Future integrated studies are required to assess the scope for flexibility in life-history strategies as this will have a critical bearing on whether birds can adapt sufficiently rapidly to anthropogenic environmental changes, in particular climate change. Expand

TLDR
A model that made use of the fact that in castrated European starlings, luteinizing hormone (LH) is low in photorefractory birds and high in photosensitive birds suggests that the mechanisms causing photostimulation andPhotorefractoriness are both initiated during the first long photoperiod. Expand
