In animals, color signals that convey information about quality are often associated with costs linked to the expression of coloration and may therefore be honest signals of sender quality. Honest indicators are often seen in sexual signals that are used by males to advertise quality to females. Carotenoid and pterin pigments are responsible for yellow, orange, and red coloration in a variety of taxa, but can also serve important roles as antioxidants by reducing free radicals in the body. In this study, we test the effects of a novel full-bodied orange color phenotype of the brown anole, Anolis sagrei, on …

Background: Previous research has identified numerous factors to explain why students have difficulty learning
about evolution. Some of these factors include a student’s background (including their religion and major of study),
the type of evolution instruction, and the inclusion of the nature of science (NOS) instruction. Sparse but more recent
work has investigated the impact of a religious-scientist role model to help dampen perceptions of conflict between
evolutionary science and worldview. We had two research goals: (1) to identify which of these factors influence
students’ learning of evolution in post-secondary education; and (2) to describe the relationships among incoming
biology …
