Chemoreception is one of the dominant sensory modalities for many species of salamanders (reviewed in Chapter 2). At least seven of the ten currently recognized salamander families are known to respond to some sort of chemical cue. These responses are as varied as delaying hatching, seeking refuge, or initiating aggressive...
Sexual selection can influence the mating system of an organism through multiple mechanisms. These mechanisms result in variation in reproductive success among individuals, and include scramble competition, endurance rivalries, contests, mate choice and cryptic choice, and sperm competition. Understanding the mating system of a species requires the identification of which...
Previous research has shown a gap between chemistry students' conceptual
and computational understandings of chemistry topics such as gas laws,
equilibrium, and reactions. This qualitative study examined the conceptual and
computational understandings of stoichiometry of college students enrolled in a
