Chamaeleo africanus DNA sequencing purity results and statistics
<p>Conservation of wildlife often depends on high quality molecular data to establish reliable species identification. Traditional approaches in extracting material (DNA) for phylogenetic studies on chameleons have relied on removed, euthanized or preserved/museum specimens, while field sampling usually takes the form of tail clippings from living individuals and their subsequent release. In this article, we propose an alternative to these approaches for field sampling, towards isolation of nuclear and mitochondrial DNA with oral (buccal) swabs, a methodology already been demonstrated as effective in other taxa. Options of sampling, storage, transport, extraction of DNA are presented and the quality and quantity of extracted material (using venipuncture as a positive control) was demonstrated as sufficient for downstream applications, including sequencing thereby presenting a practical field alternative. The advantages and limitations of this minimally invasive and non-destructive method applied to <em>Chamaeleo africanus</em> are further discussed.</p>

Data from: Alternative mating tactics in male chameleons (Chamaeleo chamaeleon) are evident in both long-term body color and short-term courtship pattern
Alternative mating tactics in males of various taxa are associated with body color, body size, and social status. Chameleons are known for their ability to change body color following immediate environmental or social stimuli. In this study, we examined whether the differential appearance of male common chameleon during the breeding season is indeed an expression of alternative mating tactics. We documented body color of males and used computer vision techniques to classify images of individuals into discrete color patterns associated with seasons, individual characteristics, and social contexts. Our findings revealed no differences in body color and color patterns among males during the non-breeding season. However, during the breeding season males appeared in several color displays, which reflected body size, social status, and behavioral patterns. Furthermore, smaller and younger males resembled the appearance of small females. Consequently, we suggest that long-term color change in males during the breeding season reflects male alternative mating tactics. Upon encounter with a receptive female, males rapidly alter their appearance to that of a specific brief courtship display, which reflects their social status. The females, however, copulated indiscriminately in respect to male color patterns. Thus, we suggest that the differential color patterns displayed by males during the breeding season are largely aimed at inter-male signaling.

Bayesian posterior probabilities are given above each node, while parsimony bootstrap values are given below each node. Although some interior nodes (within genera) were supported, only some representative values within the Trioceros are shown.
