    • The smell of environmental change: Using floral scent to explain shifts in pollinator attraction 

      Burkle, Laura A.; Runyon, Justin B. (2017-07)
      As diverse environmental changes continue to influence the structure and function of plant-pollinator interactions across spatial and temporal scales, we will need to enlist numerous approaches to understand these changes. ...
    • A new Late Cretaceous iguanomorph from North America and the origin of New World Pleurodonta (Squamata, Iguania)

      Iguanomorpha (stem + crown Iguania) is a diverse squamate clade with members that predominate many modern American lizard ecosystems. However, the temporal and palaeobiogeographic origins of its constituent crown clades ...
    • Research Microcultures as Socialization Contexts for Underrepresented Science Students 

      Thoman, Dustin B.; Muragishi, Gregg A.; Smith, Jessi L. (2017-05)
      How much does scientific research potentially help people? We tested whether prosocial-affordance beliefs (PABs) about science spread among group members and contribute to individual students\' motivation for science. We ...
    • Theorizing the decision-making process for divorce or reconciliation
