Mean LH levels increased during the spring and reached the annual maximum in April and May. In June when testicular regression occurs, the LH titer sharply decreased and was lower than at any other phase of the annual cycle. In late fall mean plasma LH concentrations increased and, whilst not reaching the values observed during the breeding season, remained relatively high during the winter. Thus, in the mallard LH can be released under short and long daily photo\u2010periods.<\/jats:p>","DOI":"10.1002\/jez.1401940312","type":"journal-article","created":{"date-parts":[[2005,6,11]],"date-time":"2005-06-11T07:08:40Z","timestamp":1118473720000},"page":"553-558","source":"Crossref","is-referenced-by-count":33,"title":["Annual cycle of plasma luteinizing hormone concentrations in wild mallard drakes"],"prefix":"10.1002","volume":"194","author":[{"given":"E.","family":"Haase","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"P.
