控制生长和繁殖的机制受到了分子和细胞内分泌学家的相当大的关注，但将生理学的这两个方面联系起来的努力相对较少。另一方面，进化生物学家长期以来一直在评论许多物种的生长和繁殖之间的关系，但通常忽略了这些复杂特征背后的机制。一种方法，集成了多个接近水平的承诺，提供显着的洞察神经内分泌控制机制的演变。在这一章中，我们采取这种方法，在豹壁虎，Eublepharis macularius的生长和繁殖审查环境的影响。在这个物种中，胚胎发育期间的孵化温度不仅决定性腺性别，而且也是生长、成体形态、攻击性、生殖生理和行为以及大脑组织的性别差异的基础。因此，豹壁虎是一个很好的模型，以阐明环境和内分泌和神经系统之间的发育相互作用，控制生长和繁殖。(C)1998年爱思唯尔科学公司All rights reserved.
The mechanisms that control growth and reproduction have received considerable attention by molecular and cellular endocrinologists, yet there has been relatively little effort to link these two aspects of physiology. On the other hand, evolutionary biologists have long commented on the relationship between growth and reproduction in many species, yet have generally neglected the mechanisms underlying such complex traits. An approach that integrates the multiple proximate levels promises to provide significant insight into the evolution of neuroendocrine control mechanisms. In this chapter, we take this approach in reviewing environmental influences on growth and reproduction in the leopard gecko, Eublepharis macularius. In this species, incubation temperature during embryonic development not only determines gonadal sex, but also underlies within-sex differences in growth, adult morphology, aggressiveness, reproductive physiology and behaviour, and brain organization. Thus, the leopard gecko is an excellent model to elucidate the developmental interactions among the environment and the endocrine and nervous systems that control growth and reproduction.
