Ontogenetic allometry of locomotor performance in basilisk lizards
Meeting Abstract 123-5 Tuesday, Jan. 7 11:00 – 11:15 Ontogenetic allometry of locomotor performance in basilisk lizards CHEU, AY*; BERGMANN, PJ; Clark University; Clark University acheu@clarku.edu http://basiliskos.com For precocious vertebrates, the need for locomotor activity begins soon after hatching or birth. Juveniles may occupy the same habitat as their adult counterparts and therefore, compete for the same […]
