Fig. 1: Comparative evidence for character displacement via shifts in behavior and habitat use.
From: Observing character displacement from process to pattern in a novel vertebrate community
A Anolis sagrei and A. cristatellus. B When in allopatry, both species occupy similar perch heights but diverge when in sympatry. Circles represent mean values from three sites per treatment; error bars are ± 1 S.E. C Lower perch height in sympatric A. sagrei populations is primarily driven by increased terrestriality (values represent mean percentage of lizards observed on the ground across three sites in each treatment). D Sympatric A. sagrei moved across the ground between plant perching sites at a significantly higher frequency relative to those in allopatry. Circles represent mean values; error bars are ± 1 S.E. P-values in (B) and (D) are from linear mixed effects models with treatment (i.e., allopatry vs. sympatry) as a fixed effect and site as a random effect. *p < 0.05; **p < 0.01. E A mixed species social network in a sympatric community (MHS) estimated from association by distance measurements. Each symbol (node) represents an individual lizard (squares = males; circles= females), and size is proportional to body size. Black lines (edges) represent the presence of inter-specific interactions between individual A. sagrei and A. cristatellus lizards; light gray edges show intra-specific interactions. Edge thickness demonstrates the strength of the interaction relationship between two individual lizards. Photo credit: Day’s Edge Prods.
