“…This results in a slowly developing and sustained increase in glutamate release in the AOB, and an increased release of the excitatory transmitters aspartate and glutamate 2 days later, in response to the pheromones to which the females had been exposed [77]. This decreased inhibitory control of mitral cells is consistent with the priming effect of pheromonal preexposure to enhance the pheromonal acceleration of puberty in prepubertal female mice [83]. It is also consistent with the finding that the exposure of male hamsters to urine from female hamsters decreases the length of the postsynaptic densities of the excitatory, glutamatergic synapses from mitral to granule cells [84].…”

In addition to the main olfactory system, many vertebrates possess a vomeronasal system that conveys more specialized chemosensory information. Unlike the airborne, volatile stimuli detected by the main olfactory system, vomeronasal stimuli are typically proteins of the lipocalin family which bind small, volatile ligands. Despite the smaller number of vomeronasal receptor types, the projection patterns of the vomeronasal receptor neurons to multiple glomeruli in the accessory olfactory bulb appear to be more complicated than those of the main olfactory system. The vomeronasal system has a direct subneocortical projection to hypothalamic areas that mediates specific behavioural and hormonal responses to pheromonal stimuli. However, the integration and transmission of this information can be modulated by learning mechanisms. The aim of this article is to outline some of the functions of the vomeronasal system, and in particular to comment on recent advances in our understanding of how vomeronasal information is coded and processed.

“…Such harsh, unpredictable features are likelier to be relatively absent from higher SES childhoods. It is possible that early exposure to environmental factors related to unpredictability and harshness may sensitize life history parameters and set developmental trajectories, including shunting individuals down a slower or faster path (e.g., Mucignat Caretta, Caretta, & Cavaggioni, 1995). Such differential calibration in childhood may lead to differentiation between individuals’ life history strategies in the face of ecological challenges.…”

Why do some people have children early, whereas others delay reproduction? By considering the trade-offs between using one’s resources for reproduction versus other tasks, the evolutionary framework of life history theory predicts that reproductive timing should be influenced by mortality and resource scarcity. A series of experiments examined how mortality cues influenced the desire to have children sooner rather than later. The effects of mortality depended critically on whether people grew up in a relatively resource-scarce or resource-plentiful environment. For individuals growing up relatively poor, mortality cues produced a desire to reproduce sooner—to want children now, even at the cost of furthering one’s education or career. Conversely, for individuals growing up relatively wealthy, mortality cues produced a desire to delay reproduction—to further one’s education or career before starting a family. Overall, mortality cues appear to shift individuals into different life history strategies as a function of childhood socioeconomic status, suggesting important implications for how environmental factors can influence fertility and family size.

“…Similarly, only heifers above a certain weight accelerate puberty in response to bull urine, presumably because of immaturity in lighter heifers (Izard, 1983). Prepubertal female mice also accelerate puberty in response to adult male urine; however, this effect is enhanced by previous, preweaning exposure to the urine of other adult males (Caretta, Caretta, & Cavaggioni, 1995). Finally, there may be a synergism between exposure to adult males and experiences of stress.…”

Life history theory provides a metatheoretical framework for the study of pubertal timing from an evolutionary-developmental perspective. The current article reviews 5 middle-level theories--energetics theory, stress-suppression theory, psychosocial acceleration theory, paternal investment theory, and child development theory--each of which applies the basic assumptions of life history theory to the question of environmental influences on timing of puberty in girls. These theories converge in their conceptualization of pubertal timing as responsive to ecological conditions but diverge in their conceptualization of (a) the nature, extent, and direction of environmental influences and (b) the effects of pubertal timing on other reproductive variables. Competing hypotheses derived from the 5 perspectives are evaluated. An extension of W. T. Boyce and B. J. Ellis's (in press) theory of stress reactivity is proposed to account for both inhibiting and accelerating effects of psychosocial stress on timing of pubertal development. This review highlights the multiplicity of (often unrecognized) perspectives guiding research, raises challenges to virtually all of these, and presents an alternative framework in an effort to move research forward in this arena of multidisciplinary inquiry.
