Abstract: Sceloporus grammicus microlepidotus is a viviparous, high altitude Mexican lizard. Specimens were obtained from several locations in the Parque Nacional de Zoquiapan, Mexico, Mexico. This species exhibits a reproductive cycle in which ovulation and fertilization occur during the fall and parturition the following spring. Vitellogenesis begins in late July in female S. g. microlepidotus, whereas the onset of testicular development occurs in February. Thus, it appears that male reproductive activity is initiated in spring, whereas female reproductive activity is initiated in the fall. The adaptive significance of fall courtship and mating in lizards is discussed.

TL;DR: The interaction between the two species is discussed and the role of functional capabilities for prey capture during these early life periods is discussed.
Abstract: The feeding habits ofGalaxias maculatus (Galaxiidae) andOdontesthes microlepidotus (Atherinidae) larvae and juveniles were studied in an Araucanian lake of Argentina. Fish specimens were grouped, on the basis of the percentage of each food category found in their gut, using multivariate methods. These groups of fishes showed significant differences in average total length. Positive correlations between prey size and fish length were also detected. Diet overlap between juvenileG. maculatus and juvenileO. microlepidotus was observed. We discuss the interaction between the two species and the role of functional capabilities for prey capture during these early life periods.
