Despite broad consensus that highlighting counter-stereotypical scientist role models in educational materials promotes equity and success, the specific elements make these effective remain untested. Are pictures of scientists enough to communicate students come from a variety backgrounds, or is additional information required? To parse effects including visual depictions humanizing about featured biology course materials, we distributed three randomized versions assignments over several...
Social traits are expected to experience highly context-dependent selection, but we know little about the contextual factors that shape selection on social behaviours. We hypothesized fitness consequences of interactions will depend age partners, and therefore population structure evolutionary pressures sociality. Here, investigate variation at multiple levels organization for both individual sexual network traits. experimentally manipulated composition populations forked fungus beetle...
Abstract Background We used an opportunity gap framework to analyze the pathways through which students enter into and depart from science, technology, engineering, mathematics (STEM) degrees in R1 higher education institution better understand demographic disparities STEM degree attainment. Results found 6-year graduation rates on basis of gender, race/ethnicity, parental level. Using mediation analysis, we showed that gender disparity attainment was explained by aspiration: a students’...
Traditional biology curricula depict science as an objective field, overlooking the important influence that human values and biases have on what is studied who can be a scientist. We work to address this shortcoming by incorporating ideological awareness into curriculum, which understanding of biases, stereotypes, assumptions shape contemporary historical science. surveyed national sample lower-level instructors determine 1) why it for students learn science, 2) perceived educational value...
Increasingly, curricular materials for undergraduate life science courses are designed to highlight scientists with identities and backgrounds that counter historical stereotypical representation in science. In this essay, we characterize the wide variation development implementation of these featuring counterstereotypical scientists. Applying Social Ecological Model Behavior Change as a framework, examine both personal social elements benefits costs related designing implementing curricula...
Abstract Highlighting scientists from historically excluded groups in educational materials increases student engagement STEM. However, which specific elements of these maximize their impact remains untested, leaving educators guessing how to best highlight counter-stereotypical classrooms. We tested the effects including visual and humanizing descriptions featured quantitative biology activities on over 3,700 students across 36 undergraduate institutions. found that information about...
AbstractSocial behaviors vary among individuals, and social networks groups. Understanding the causes of such variation is important for predicting or altering ecological processes as infectious disease outbreaks. Here, we ask whether age contributes to in behavior at multiple levels organization: within individuals over time, different ages, local environments, populations. We used experimental manipulations captive populations a longitudinal dataset test associated with across these...
Darwin viewed the ornamentation of females as an indirect consequence sexual selection on males and transmission male phenotypes to via 'laws inheritance'. Although a number studies have supported this view by demonstrating substantial between-sex genetic covariance for ornament expression, majority work has focused avian plumage. Moreover, few considered basis ornaments from multivariate perspective, which may be crucial understanding evolution sex differences in general, complex...
Featuring a diversity of scientists within curriculum provides opportunities for students to relate them. We manipulated the amount and type information received about scientists. found including personal, humanizing increased extent which related them, with implications development.
Social network structure is a critical group character that mediates the flow of information, pathogens and resources among individuals in population, yet little known about what shapes social structures. In this study, we experimentally tested whether depends on personalities individual members. Replicate groups forked fungus beetles ( Bolitotherus cornutus ) were engineered to include only members previously assessed as either more or less social. We found expressed consistent across...
Both individual and group behavior can influence fitness, but multilevel selection is rarely quantified on social behaviors. Social networks provide a unique opportunity to study behaviors, as they describe complex traits patterns of interaction at both the levels. In this study, we used contextual analysis measure consequences network position structure fitness in experimental populations forked fungus beetles (Bolitotherus cornutus) with two different resource distributions. We found that...
Physiology, physics, and ecological interactions can generate trade-offs within species, but may also shape divergence among species. We tested whether signal in Oecanthus tree crickets is shaped by acoustic, energetic, behavioral trade-offs. found that species with faster pulse rates, produced opening closing wings up to twice as many times per second, did not have higher metabolic costs of calling. The relatively constant energetic cost across explained between the duration repetition rate...
Social interactions drive many important ecological and evolutionary processes. It is therefore essential to understand the intrinsic extrinsic factors that underlie social patterns. A central tenet of field behavioural ecology expectation distribution resources shapes patterns interactions. We combined experimental manipulations with network analyses ask how resource influence complex experimentally manipulated an food reproductive in semi-natural populations forked fungus beetles...
Racial biases, which harm marginalized and excluded communities, may be combatted by clarifying misconceptions about race during biology lessons. We developed a human genetics laboratory activity that challenges the misconception is biological (biological essentialism). assessed relationship between this student outcomes using survey of students' attitudes essentialism color-evasive ideology concept inventory phylogeny diversity. Students in showed significant decrease their acceptance...
Abstract Optimum storage conditions for eggs of Aedes vexans (Meigen) were found to be a temperature 2 °C and saturated atmosphere. These are also suitable storing abserratus (Felt Young) but this species can stored at lower temperatures. When both placed in hatching medium °C, begins A . not comparable hatch the latter occurs 10°–15 °C. Desiccation death embryos occur rapidly low relative humidity (20%) high (21 °C) slowly (4 °C). Eggs that lose substantial amount water will still larvae...
Social interactions with conspecifics can dramatically affect an individual's fitness. The positive or negative consequences of interacting social partners typically depend on the value traits that they express. These pathways selection connect and genes expressed in some individuals to fitness realized by others, thereby altering total phenotypic evolutionary response across multivariate phenotype. downstream effects are mediated patterns assortment between focal their (the interactant...

Abstract Aedes vexans (Meigen) eggs which lose water under conditions of constant atmospheric saturation deficiencies, gain when transferred to a saturated atmosphere. Water loss is influenced by age. At relative humidities 80% and 50%, temperatures 10° 21 °C, that were 28 days old lost less than 14 old. Eggs up 34% their weight through desiccation regained 91% within 3 in Embryos remained viable. 68% original rendered inviable only 33% the
Discipline-based education research-a field of research that investigates teaching and learning within STEM disciplines-has emerged over the last few decades to improve quality worldwide. Simple qualitative questions concerning career backgrounds motivations individuals who conduct this have yet be explored. Here, we surveyed interviewed discipline-based researchers about their trajectories pursue research. We focused specifically on recruiting biology faculty members at colleges...
