Neuroendocrine responses play a critical role in reproduction in every mammalian species, including voles (Richmond S. Stehn, 1976). Disruption of these normal responses can result in: (1) abnormal sexual maturation; (2) abnormal or absent female cycles; (3) pseudopregnancy; (4) blocked pregnancies; or (5) the total absence of courtship and mating. Each of these factors in turn plays a considerable role in population dynamics, especially population density. Therefore, mechanisms which disrupt normal neuroendocrine function could affect population dynamics and reduce population density by affecting changes in one or many of these reproductive processes.
