Winter aggregation in Anolis equestris and A. lucius (Squamata: Dactyloidae), two territorial species from Cuba

Sexual maturation in free-ranging Chilabothrus angulifer (Serpentes: Boidae)

“…Despite year-round air temperatures in Cuba could seem high enough as to ensure adequate rates of embryonic development in Antillean viviparous snakes (Tolson and Henderson 1993), the synchrony observed in parturitions suggest that even the small differences between seasons have reproductive cycles. Mean air temperatures in Cuba can drop more than 5 o C during the coolest Sexual maturation in the boid snake Chilabothrus angulifer and above 35°C in summer are not rare (data provided by the Instituto de Meteorología of Cuba, at the request of the authors), triggering even winter aggregation in highly territorial reptiles like anoles (Marrero et al 2016). Also, despite hot caves (with year-round favorable and stable thermal conditions) are widespread in Cuba (Longueira 2006), we consider they are not representative enough of the species range and subpopulations during pregnancy, being unlikely that this caves have functioned as selective pressure toward a trend for females to reproduce year-round using this sites for thermoregulation.…”
