The types of mutations affecting adaptation in the wild are only beginning to be understood. In particular, whether structural changes shape adaptation by suppressing recombination or by creating new mutations is unresolved. Here we show that multiple, linked but recombining loci underlie cryptic color morphs of Timema chumash stick insects. In a related species, these loci are found in a region of suppressed recombination, forming a supergene. However, in seven species of Timema we find...

This repository accompanies a project examining the extent to which behavioral indicators of engagement from digital log data are associated with various student learning outcomes above and beyond self-reported levels of engagement, and whether the strength of these associations vary depending on the type of learning outcome

Simpson's fossil-record inspired model of ‘adaptive zones’ proposes that evolution is dominated by small fluctuations within adaptive zones, occasionally punctuated by larger shifts between zones. This model can help explain why the process of population divergence often results in weak or moderate reproductive isolation (RI), rather than strong RI and distinct species. Applied to the speciation process, the adaptive zones hypothesis makes two inter-related predictions: (i) large shifts between zones are relatively rare, (ii) when...

For insect species in temperate environments, seasonal timing is often governed by the regulation of diapause, a complex developmental program that allows insects to weather unfavorable conditions and synchronize their lifecycles with available resources. Diapause development consists of a series of distinct phases including initiation, maintenance, termination, and post-diapause development. The evolution of insect seasonal timing depends in part on how these phases of diapause development and post-diapause development interact to affect variation in phenology....

In vertebrates, glucocorticoid secretion occurs in response to energetic and psychosocial stressors that trigger the hypothalamic-pituitary-adrenal (HPA) axis. Measuring glucocorticoid concentrations can therefore shed light on the stressors associated with different social and environmental variables, including dominance rank. Using 14,172 fecal samples from 237 wild female baboons, we test the hypothesis that high-ranking females experience fewer psychosocial and/or energetic stressors than lower-ranking females. We predicted that high-ranking females would have lower fecal glucocorticoid (fGC) concentrations...

During the Spring 2020 semester, K-12 teachers and students throughout the U.S. adapted from a face-to-face to a fully online teaching format. To better understand these experiences, seven AP Statistics teachers were interviewed following a semi-structured protocol.

Are high school students accurate in predicting their test performance? If so, do their predictions explain variation in performance, even after accounting for other factors? We examined these questions in two testing contexts (low-stakes and high-stakes) among students enrolled in a high school advanced placement (AP) statistics class.

1. Individual-level demographic outcomes should be predictable upon the basis of traits. However, linking traits to tree performance has proven challenging likely due to a failure to consider physiological traits (i.e., hard-traits) and the failure to integrate organ-level and whole plant-level trait information. 2. Here, we modeled the survival rate and relative growth rate of trees while considering crown allocation, hard-traits, and local-scale biotic interactions, and compared these models to more traditional trait-based models of...

We attempted to confirm an appropriate factor structure of the BFI-2 given a sample of adolescents. After controlling for acquiescence, the findings generally suggest that both the correlated facets and the correlated residuals model are appropriate factor structures for the BFI-2 with a sample of adolescents. Modeling one domain (open-mindedness) proved elusive given the present measure. Using a measure on children and adolescents developed on an adult sample can be dubious, and in light of...

Since the outbreak of coronavirus disease 2019 (COVID-19) in Wuhan, China, it has rapidly spread across many other countries. While the majority of patients were considered mild, critically ill patients involving respiratory failure and multiple organ dysfunction syndrome are not uncommon, which could result death. We hypothesized that cytokine storm is associated with severe outcome. We enrolled 102 COVID-19 patients who were admitted to Renmin Hospital (Wuhan, China). All patients were classified into moderate, severe...

In humans and other long-lived species, harsh conditions in early life often lead to profound differences in adult life expectancy. In response, natural selection is expected to accelerate the timing and pace of reproduction in individuals who experience some forms of early life adversity. However, the adaptive benefits of reproductive acceleration following early adversity remain untested. Here we test a recent version of this theory, the internal predictive adaptive response (iPAR) model, by assessing for...
