“…This feature has likely been considered when giving these taxa species status. However, intraspecific variation in the degree of sexual dichromatism is known in other great speciators including Pachycephala pectoralis (Andersen et al., ) and Petroica multicolor (Kearns et al., ). It might therefore be a characteristic with a common genetic basis (Cornetti et al., ) that facilitates the early (parapatric) diversification of great speciators.…”

“…Several molecular studies of avian diversity in the Indo‐Pacific have resulted in elevating subspecies to species rank (Irestedt et al., ; Kearns et al., ) or recognizing polytypic taxa as multiple incipient species (Andersen, Hosner, Filardi, & Moyle, ). Contrary to this trend, this study suggests the inclusion of five currently recognized species into one single species complex.…”

“…The Australo‐Papuan region is thought to be the source of several (downstream) colonizations into the Indo‐Pacific archipelagos (Garcia‐Ramirez et al., ; Kearns et al., ). The Campephagidae (cuckoo‐shrikes and allies), which is one of the most species‐rich families of the Corvides (sensu Cracraft, ), originated in this region (Jønsson, Fabre, Ricklefs, & Fjeldså, ).…”

Aim We derive a new phylogenetic framework of the Indo‐Pacific avian genus Edolisoma based on a dense taxon sampling and use it in an explicit spatiotemporal framework to understand the history of intraspecific diversification dynamics in a ‘great speciator’, the Cicadabird Edolisoma tenuirostre/remotum complex. Location The Indo‐Pacific island region, Australia and New Guinea. Taxon Corvoid passerine birds (Passeriformes). Methods We used Bayesian phylogenetic methods (beast) to construct a time‐calibrated molecular phylogeny of all 19 species in the genus Edolisoma and 27 of 29 subspecies of the E. tenuirostre/remotum complex (previously Coracina tenuirostris) primarily based on one mitochondrial DNA marker. Ancestral area reconstruction methods (‘BioGeoBEARS’) were used to infer the historical biogeography of the genus. We used population‐level analyses to assess intraspecific phylogeography and a molecular species delimitation test to evaluate the current taxonomy. A morphometric dataset was used to discuss differential dispersal ability among taxa. Results Edolisoma originated in the late Miocene and diversification within the E. tenuirostre/remotum complex began in the Pleistocene. Within the North Melanesian and North Wallacean archipelagos, which have experienced several waves of diversification, we find significant patterns of genetic isolation by distance, but not within the Australo‐Papuan ‘mainland’, which was recently back‐colonized from these archipelagos. Based on the phylogeny, we suggest several taxonomic changes. We also discuss evidence of taxon cycles within Edolisoma based on correlations of species age, elevational ranges and dispersal ability. Main conclusions The biogeographical history and patterns of differentiation between phylogroups within E. tenuirostre support the importance of barriers to gene flow in island systems. Examples of both recent genetic exchange across significant sea barriers and differentiation across much smaller water gaps suggest complex dispersal and diversification dynamics. The capacity for dispersal away from islands, and gradual shifts in dispersal ability in relation to the geographical setting, is supported as important factors in generating a ‘great speciator’.

“…We also used our analysis of the domain to define how to present evidence to students, such that the tasks require students to make sense of data within the boundaries of assessment appropriate to high school students. For example, a candidate study involved an evaluation of the similarity of populations’ alleles that presented results from a Bayesian statistical analysis (Kearns et al, ). However, most high school students are not exposed to these kinds of statistics, and the NGSS boundary statements are explicit about limiting assessment to basic concepts of statistics and probability when assessing the SEP of using mathematics and computational thinking.…”

Developing tasks to assess phenomenon‐based science learning: Challenges and lessons learned from building proximal transfer tasks

The vision for science proficiency presented in A Framework for K‐12 Science Education calls for significant shifts in both teaching and assessment. In this paper, we describe an effort to develop and validate a set of proximal transfer tasks for high school biology classrooms where teachers were implementing a problem‐based curriculum. The proximal transfer tasks presented students with phenomena related to but distinct from the phenomena they had studied in class and asked students to apply their understanding of disciplinary core ideas, practices, and crosscutting concepts targeted in curriculum. We tested these tasks with a sample of 733 students from 11 teachers’ classes. Each of these students completed two tasks before beginning the unit and two tasks after they had finished the unit. We found that nearly all pretest and posttest task pairs were aligned to written opportunities to learn in the curriculum, that is, students showed significant growth over the course of a unit. In addition, task pairs revealed differences across teachers. However, the relative growth of students depended on which tasks students completed, indicating wide variation in task difficulty. Our findings point to the potential of developing three‐dimensional proximal transfer tasks and to the difficulty of constructing equivalent tasks.
