, captive breeding, and restoration ecology of endangered fishes.
Presumably, ghrelin as a starvation hormone in low physiological doses has a negligible effect on mating behavior but continuity of ghrelin release has a remarkable effect on reproductive behavior
This study shows how the ages of menarche, entry to union with a partner, first pregnancy, and first delivery among Embera Chamibida women come later when compared to Embera Eyabida and Zenu women; this pattern of reproductive behavior
is classified in other studies as divergent with respect to the situation of the rest of the indigenous women from Antioquia (6,7,15) In these studies as in the current one, the differential reproductive behavior
of the Chamibida women is related to the continued interethnic contact that has supposed that this subgroup adopts practices of the Western culture, which often go against the Embera cultural guidelines that promote population growth as an input for ethnic survival.
plei, especially those related to reproductive behavior
, was constructed.
Salient in the current analysis is the fact that family environment interacted with abuse status in the prediction of both teenage pregnancy and teenage childbearing, suggesting the potential scope of family influence to be considerable in terms of subsequent adolescent female sexual and reproductive behavior
Finally, we used laboratory cultures to study similarities and differences in predatory and reproductive behaviors
To date, no study has specifically examined and compared long-term trends in adolescent sexual and reproductive behavior
in EI Salvador, Guatemala, Honduras and Nicaragua.

and Evolution of the Tettigoniidae.
For each species, the guides also discuss habitat, range, reproductive behavior
, and other, similar-looking fish.
This collection of 18 extended articles focuses on specific issues, including techniques and events leading to a fertilizable oocyte, physiological functions of gonadotropins, functions and patterns of change in gonadal steroids, vitellogenesis, follicular steroidogenesis, hormonally derived sex pheromones, reproductive physiology in viviparous teleosts, mating systems, reproductive strategies, cost-benefit comparisons in energy investments, reproductive behavior
in shoaling fish, parental care and predator risk, the impact of environmental factors on fish endocrinology, shark reproductive ecology, estrogen pathways, molecular markers of androgen disruption, concerns about the effects of aquaculture, and fish reproduction within cultivation of cold water marine species.
Garcia (1985) also concluded that reproductive behavior
of shrimp species respond to transition periods of temperature.
