... species in which the mandible functions as a single structure rotating only at the quadratomandibular joint (QMJ). In this study, we examine kinematic consequences of the IMJ novelty in a freshwater characiform fish, the herbivorous Distichodus sexfasciatus . We combine traditional kinematic approaches...

... behavioral mechanisms underlying ecological novelty is by comparing prey capture kinematics among species. We investigated the contribution of kinematics to the origins of a novel ecological niche for scale-eating within a microendemic adaptive radiation of pupfishes on San Salvador Island, Bahamas. We...

... ; Laurence et al., 2015 ). We can exclude the effects of novelty-induced stress, because control snails were also kept in a new container with fresh water and more intense light than in the original aquarium. More severe acute stressors, such as occasional damage to a snail or a strong tactile stimulus...

... a shrimp diet such that development slowed, growth ceased, and CORT synthesis and secretion increased to a level similar to that of tadpoles that were not fed. The novelty of giving tadpoles adult shrimp after 3 days of eating nauplii did not appear to cause the stress response; tadpoles that were raised...

... but in the presence of a trail previously laid by the same group of individuals, they prefer the path with the trail, irrespective of orientation. However, cockroaches tended to avoid trails laid by a different group of cockroaches. Overall, our results indicate that both scent cues and response to novelty influence...
