Nutrition, reproduction, and behavior

2002
Publisher Summary The relationship between nutrition and reproduction is demonstrated in species from every mammalian order, including primates. Successful pregnancy and lactation require tremendous amounts of energy. Ovulatory cycles, mating behavior, steroidogenesis, and lactation are inhibited by caloric restriction, especially in small mammals ...

Reproductive Behavior

2018
Sex and reproduction lie at the heart of studies of insect behavior. We begin by providing a brief overview of insect anatomy and physiology, followed by an introduction to the overarching themes of parental investment, sexual selection, and mating systems.

Hormonal mediation of reproductive behavior

Journal of Experimental Zoology, 1984

Household crowding and reproductive behavior

Biodemography and Social Biology, 1992
Ethological studies suggest that animal populations that live in crowded conditions display a number of behaviors that tend to limit the size of the population, such as aberrant forms of sexual behavior, small litter sizes, a higher incidence of spontaneous abortion, ineffectual maternal care, and even cannibalism of their young.

Reproductive and Maternal Behavior of Livestock

2014
This chapter describes the reproductive and maternal behaviors of different livestock species (cattle, horses, pigs, goats, and water buffalo) with an emphasis on those traits which are genetically conserved. All of the species discussed are polygynous and promiscuous, and females undergo estrous cycles in which males are mainly attracted by movement ...

A peptidergic circuit for reproductive behavior

Brain Research, 1992
A projection from the medial amygdaloid nucleus to the hippocampus and septum probably uses vasopressin as a transmitter. The nucleus synthesizes vasopressin and activation of the nucleus has a hippocampal effect that is completely blocked by a vasopressin antagonist.

The conference on reproductive behavior: a history

Hormones and Behavior, 2003
The Society for Behavioral Neuroendocrinology was, in part, an outgrowth of the Conference on Reproductive Behavior, which was, in turn, an outgrowth of the West Coast Sex Meetings. In this article I trace the history of these organizations. The West Coast meetings provided an opportunity for free and informal exchange among west coast researchers ...
