Photoperiodic Regulation of Seasonal Breeding in Birds
Abstract
Day length-dependent breeding in birds commonly occurs in spring and summer, but may occur after exposure to complex changes in day length, as for example in transequatorial migrants. More rarely, some photoperiodic birds breed when day lengths are decreasing or are short. The flexibility of avian photoperiodic breeding strategies may reflect modifications to a common reproductive photoperiodic neuroendocrine system. This involves an extraretinal photoreceptor and a biological clock, which generates a circadian rhythm of photoinducibility to measure photoperiodic time. The pineal gland is not essential for the reproductive photoperiodic response. The current model of the avian photoperiodic response has been modified to accommodate short day breeders, by incorporating a role for seasonal changes in prolactin secretion in the termination of breeding. Analysis of the sites of expression of clock genes suggests that the biological clock for reproductive photoperiodic time measurement is in the medial basal hypothalamus. Photoperiodic signal transduction may involve a clock-dependent local conversion of thyroxine to triiodothyronine (T(3)) in the medial basal hypothalamus mediated by increased expression of the gene encoding type 2 iodothyronine deiodinase. This photoinduced increase in T(3) may stimulate the release of gonadotrophin-releasing hormone (GnRH) through thyroid hormone receptors in the median eminence. These may mediate retraction of glial cell end-feet ensheathing GnRH nerve terminals abutting onto the hypophysial portal vasculature, allowing GnRH to be released to stimulate gonadotrophin secretion.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
