Ancient DNA from coral-hosted Symbiodinium reveal a static mutualism over the last 172 years.

Ancient DNA (aDNA) provides powerful evidence for detecting the genetic basis for adaptation to environmental change in many taxa. Among the greatest of changes in our biosphere within the last century is rapid anthropogenic ocean warming. This phenomenon threatens corals with extinction, evidenced by the increasing observation of widespread mortality following mass bleaching events. There is some evidence and conjecture that coral-dinoflagellate symbioses change partnerships in response to changing external conditions over ecological and evolutionary timescales. Until now, we have been unable to ascertain the genetic identity of Symbiodinium hosted by corals prior to the rapid global change of the last century. Here, we show that Symbiodinium cells recovered from dry, century old specimens of 6 host species of octocorals contain sufficient DNA for amplification of the ITS2 subregion of the nuclear ribosomal DNA, commonly used for genotyping within this genus. Through comparisons with modern specimens sampled from similar locales we show that symbiotic associations among several species have been static over the last century, thereby suggesting that adaptive shifts to novel symbiont types is not common among these gorgonians, and perhaps, symbiotic corals in general

The effects of peer teaching on undergraduate music majors\u27 achievement and attitude toward sight-reading in the group piano setting

The purposes of this study were: (1) to investigate the effects of peer teaching on students’ achievement in sight-reading at the piano, and (2) to determine whether peer teaching positively affected students’ attitude toward sight-reading at the piano. Participants were undergraduate music majors (N = 85) enrolled in the second or fourth semester of a four-semester group piano sequence. Participants completed a pretest and a posttest that consisted of a video-taped sight-reading performance and an attitudinal questionnaire. Control and experimental groups comprised the treatment groups for each level. Group Piano IV and Group Piano II participants in the experimental group were paired, creating 23 dyads. Dyads participated in eight peer teaching sessions across the semester; Group Piano IV participants served as tutors while Group Piano II participants served as tutees. Peer teaching sessions occurred outside scheduled class time and consisted of sight-reading duet and solo repertoire. The control group also participated in eight sight-reading sessions outside scheduled class time. These sessions were completed individually and did not involve peer teaching. Two-Way ANOVAs with repeated measures revealed a significant difference due to the main effect of treatment groups in Group Piano II, but not in Group Piano IV. A significant difference due to the main effect of the test was found in both levels of group piano. A significant interaction between tests and treatment groups was found in Group Piano IV, but not in Group Piano II. Therefore, all participants significantly improved from pretest to posttest. This improvement only differed significantly across control and experimental groups for Group Piano IV, suggesting that peer teaching may positively affect peer tutors’ achievement in sight-reading. Two-Way Chi Square tests were calculated for each questionnaire item in both levels; one questionnaire item significantly changed in attitudinal response. Group Piano II participants in the experimental group felt more confident maintaining continuity while sight-reading than at the beginning of the semester compared to Group Piano II participants in the control group. This study offers empirical evidence to support the idea that peer teaching may help increase peer tutees’ confidence in maintaining continuity while sight-reading at the piano
