Cope's arboreal alligator lizard of the pet trade. Cope's arboreal alligator lizard, also known as "Abronia aurita", is a species of alligator lizard found only in roughly 400 square kilometers of Guatemala. Specifically, the only suitable habitat for this species is between 2,000 and 2,600 feet above sea level on the west and south sides of Sierra de Xucaneb in the Department of Alta Verapaz. These species are considered arboreal, meaning they live in trees. They prefer to make their homes in the trunks of decaying, large trees, found in Oak or Pine forests. High tree density is considered optimal for these creatures as
Sexual dimorphism in non-human primates to the likelihood of higher vulnerability to predators. Another hypothesis suggests that arboreal primates have limitations on their upper body size, given that larger body size could disrupt their usage of terminal branches for locomotion. However, among some species of guenons ("Cercopithecus"), arboreal blue monkeys ("C. mitis") appear to be more sexually dimorphic than terrestrial vervet monkeys ("C. aethiops"). It has been hypothesized that niche divergence between the sexes attributes to the evolution of size dimorphism in primates. Males and females are known to have different preferences for ecological habitat due to different reproductive activities, which could possibly lead to
