In wild mallard drakes plasma FSH and LH levels were elevated at the height of the breeding season in spring, decreased towards the end of the reproductive phase and were low during the time of photorefractoriness in summer, when the testes were regressed. In contrast plasma prolactin concentrations increased only towards the end of the breeding season

Cell reproduction cycle of mycoplasma

Biochimie, 1999
The cell reproduction cycle of parasitic wall-free bacteria, mycoplasma, is reviewed. DNA replication of Mycoplasma capricolum starts at a fixed site neighboring the dnaA gene and proceeds to both directions after a short arrest in one direction. The initiation frequency fits to the slow speed of replication fork and DNA content is set constant.

An Ethnography of the Navajo Reproductive Cycle

American Indian Quarterly, 1982
All aspects of the reproductive cycle were considered in a research project conducted on the Navajo reservation in 1978.1 The research, which focused on menopause, had two goals: (1) to describe menopause for a non-industrial society, and (2) to test hypotheses regarding potential cultural influences in the experience of menopausal symptoms. The Navajo
