Summer Distribution

To determine past distribution and relative abundance of caribou (Rangifer tarandus caribou) in the Hudson Plains Ecozone (HPE) of Ontario, we reviewed past HPE-wide winter systematic aerial surveys, partial winter systematic surveys, summer photographic surveys, incidental observations of caribou, and other sources of information from the period 1950—2003. We conducted new HPE-wide aerial surveys in February 2003 and 2004 to evaluate current distribution patterns. From this information, we defined 9 core wintering areas in the HPE and differentiated between 3 catego¬ries of relative abundance. Wintering areas for the January—March period have changed relatively little over the past 45 years. Summer distribution of caribou along the Hudson Bay coast apparently shifted or expanded from the area west of the Severn River to the central and eastern portions of the coast since the 1980s, and caribou observations have become much more common in the area east of the Winisk River since 1998. Because major resource development activities in the HPE are proposed and some are imminent, we recommend additional caribou surveys to document current caribou population identity, size, and distribution, and research projects to better define caribou wintering areas, calving areas, and movement patterns in the HPE.

The Way

The way we view species distribution patterns, particularly at the level commonly referred to as the “community”, has changed over the past 70 years in biology and, subsequently, in paleontology. Because the degree to which species associations can be interpreted as ecological and evolutionary units depends ultimately on recognition and interpretation of faunal spatial variability, we need to understand the nature of this variability at all levels of resolution before we can adequately address questions of “community” structure and dynamics. While it is possible to recognize spatial variability at several levels, from the distributions of individuals within a species to the overall pattern created by the global biota, we must ask whether these patterns really comprise a hierarchy with natural discontinuities (Fig. 1), or whether it is more realistic to view them as a continuous variability spectrum.

Abstract Background CPD educators and CME providers would benefit from further insight regarding barriers and supports in obtaining CME, including sources of information about CME. To address this gap, we sought to explore challenges that clinicians encounter as they seek CME, and time and monetary support allotted for CME. Methods In August 2018, we surveyed licensed US clinicians (physicians, nurse practitioners, and physician assistants), sampling 100 respondents each of family medicine physicians, internal medicine and hospitalist physicians, medicine specialist physicians, nurse practitioners, and physician assistants (1895 invited, 500 [26.3%] responded). The Internet-based questionnaire addressed barriers to obtaining CME, sources of CME information, and time and monetary support for CME. Results The most often-selected barriers were expense (338/500 [68%]) and travel time (N = 286 [57%]). The source of information about CME activities most commonly selected was online search (N = 348 [70%]). Direct email, professional associations, direct mail, and journals were also each selected by > 50% of respondents. Most respondents reported receiving 1–6 days (N = 301 [60%]) and $1000–$5000 (n = 263 [53%]) per year to use in CME activities. Most (> 70%) also reported no change in time or monetary support over the past 24 months. We found few significant differences in responses across clinician type or age group. In open-ended responses, respondents suggested eight ways to enhance CME: optimize location, reduce cost, publicize effectively, offer more courses and content, allow flexibility, ensure accessibility, make content clinically relevant, and encourage application. Conclusions Clinicians report that expense and travel time are the biggest barriers to CME. Time and money support is limited, and not increasing. Online search and email are the most frequently-used sources of information about CME. Those who organize and market CME should explore options that reduce barriers of time and money, and creatively use online tools to publicize new offerings.

The William T. Grant Foundation supports eight consortia, each devoted to a specific issue, and each consisting of ten to twenty members from a Variety of scientific disciplines. Our purpose is to provide a forum for discussion of ideas, research, and conceptual and theoretical bases of that research to individuals who work in related areas, but who might not under other circumstances have easy communication with each other, especially in the preliminary stages of the development of their research projects. By the time national meetings occur, projects are of necessity completed, and there is no chance for modification using an interdisciplinary approach. We have been very pleased with this device to bring research workers of different disciplines together. The newest of these consortia is devoted to the Developmental Psychobiology of Stress and includes pediatricians, psychologists, and anthropologists who work on both human and animal models. This group moved promptly in their first meeting to bring together a talented group of researchers from different disciplines; the results of their research are presented in this supplement. They well exemplify the advances that have been made in recent years in methodology to study mind-body interactions in infants and older children. Methodologic barriers in the past have limited research on stress in humans. It is stimulating and exciting to see that these barriers are beginning to be overcome, and that research such as is presented here is illuminating this exciting new field. It has enormous application to pediatric practice and child health in the future.

The rapid spread of technologies involving the application of “Genetic Modification (GM)” raised the need for science communication on this new technology in society. To consider the communication on GM in the society, an understanding of the current mass media is required. This paper shows the whole picture of newspaper discourses on GM in Japan. For the Japanese public, newspapers represent one of the major sources of information on GM. We subjected the two Japanese newspapers with the largest circulation, the Asahi Shimbun and Yomiuri Shimbun, to an analysis of the full text of approximately 4000 articles on GM published over the past to perform an assessment of the change of reportage on GM. As for the most important results, our analysis shows that there are two significant shifts with respect to the major topics addressed in articles on GM by Japanese newspapers.

Wintering Area

Many animals migrate to take advantage of temporal and spatial variability in resources. These benefits are offset with costs like increased energetic expenditure and travel through unfamiliar areas. Differences in the cost-benefit ratio for individuals may lead to partial migration with one portion of a population migrating while another does not. We investigated migration dynamics and winter site fidelity for a long-distance partial migrant, barren ground caribou (Rangifer tarandus granti) of the Teshekpuk Caribou Herd in northern Alaska. We used GPS telemetry for 76 female caribou over 164 annual movement trajectories to identify timing and location of migration and winter use, proportion of migrants, and fidelity to different herd wintering areas. We found within-individual variation in movement behavior and wintering area use by the Teshekpuk Caribou Herd, adding caribou to the growing list of ungulates that can exhibit migratory plasticity. Using a first passage time–net squared displacement approach, we classified 78.7% of annual movement paths as migration, 11.6% as residency, and 9.8% as another strategy. Timing and distance of migration varied by season and wintering area. Duration of migration was longer for fall migration than for spring, which may relate to the latter featuring more directed movement. Caribou utilized four wintering areas, with multiple areas used each year. This variation occurred not just among different individuals, but state sequence analyses indicated low fidelity of individuals to wintering areas among years. Variability in movement behavior can have fitness consequences. As caribou face the pressures of a rapidly warming Arctic and ongoing human development and activities, further research is needed to investigate what factors influence this diversity of behaviors in Alaska and across the circumpolar Arctic.

Use Of Assessment

Artiklen skitserer kort de sidste 40-50 års udvikling i naturfagene op til det nuværende fokus på undersøgelsesbaseret undervisning og udvikling af kompetencer. Den påpeger hvorledes mange traditionelle evalueringsformer, især brugt ved eksamen, ikke er i stand til at indfange de ønskede kompetencer, hvorfor de har svært ved at slå igennem i den daglige undervisning. Med udgangspunkt i en model af sammenhængene mellem formativ og summativ brug af evaluering argumenteres for nødvendigheden af større alignment mellem naturfagenes formål, pædagogik og evalueringsformer. Artiklen giver eksempler fra en række danske og internationale forskningsprojekter på udvikling og implementering af evalueringsformer, der kan indfange de nye læringsmål og som brugt formativt kan fremme deres læring. Den viser hvilke muligheder og udfordringer de rummer for lærere, og hvorledes en meget struktureret brug af evalueringer kan risikere at elevmotivationen forskydes fra en mestringsorientering hen mod en præstationsorientering. Afslutningsvis bliver der peget på forskellige måder til at håndtere modsætningerne mellem en formativ og en summativ brug af evalueringer. Dels gennem tiltag, der mindsker karakterpresset i skolen, og dels gennem udvikling af nye eksamensformer, der er i bedre overensstemmelse med en kompetenceorienteret undervisning.Nøgleord: kompetencer, evaluering, naturfag, motivation, karakterer Assessment of science competencesAbstractThe article briefly outlines the past 40-50 years of development in science education up to the current focus on inquiry-based teaching and competence development. It points out how many traditional forms of assessment, especially used for examinations, are unable to capture the desired competences, which makes them difficult to realize in daily teaching.Based on a model of the relationships between formative and summative use of assessment, it is argued for the need for greater alignment between the goals in science subjects, teaching and assessment. The article provides examples from a number of Danish and international research projects on the development and implementation of assessment methods that can capture the new learning objectives and which used formatively can promote their learning. It demonstrates what opportunities and challenges they have for teachers, and how a highly structured use of assessment may risk shifting student motivation from a mastering orientation towards a performance orientation. In conclusion, different ways are identified to deal with the contradiction between a formative and a summative use of assessment. Partly through actions that reduce the level of pressure in school for high marks, and partly through the development of new forms of assessment that are in better accordance with a competence-oriented education.Keywords: competences, assessment, science education, motivation, grading

This checklist of oribatid mites of the Republic of Colombia compiles and provides a taxonomic update of all records known up to 2020. It includes 192 entries accounting for 68 named and 47 unnamed species belonging to 73 genera and 58 families of non-astigmatid oribatid mites. Specimens from the brachypyline supercohort were dominant (54.7%), followed by Mixonomata (30.7%). However, current knowledge is far from being complete and distribution patterns show large gaps throughout the country due to this lacking knowledge and most existing investigations only include group specific studies that prevent from any conclusions regarding the real community composition of oribatids in Colombia. From 32 political-administrative departments, oribatids have been reported in 20, but 5 account for 65% of the records. These are: Cundinamarca -including Bogotá D.C.- (24.4%), Magdalena (21.8%), Nariño (6.3%), La Guajira (6.3%), and Quindío (5.9%). Whereas most oribatid reports in the Neotropical region have taken place during the past five decades, a map presented in this document shows that Colombia still lags behind other Latin American countries. Mexico, Argentina, and Brazil, for instance, have reported the highest number of species for the region and are the only nations that possess national oribatid checklists in Latin America. The current work represents a national baseline of oribatids encouraging further study of this clearly underrepresented group.

Teacher research has become a well-known term in professional development circles, yet it is still often misunderstood. This chapter seeks to facilitate those who are interested in teacher research by providing a historical perspective. Understanding the development of teacher research over that past century will allow interested parties to move forward with greater insight of the potential benefits and drawbacks inherent in teacher research. Such an analysis may lead to increased success for teacher research projects as the twenty-first century unfolds. Although teacher research can be a challenging form of professional development, it has incredible transformative potential. It has the potential to enhance the entire profession of teaching as well as the knowledge, skills and abilities of individual teachers. A call is made for teachers and academics to move forward by forming an alliance to explore new models and methods of teacher research.
