ABSTRACT
The Amazon River Basin's extraordinary social-ecological system is sustained by various water phases, fluxes, and stores that are interconnected across the tropical Andes mountains, Amazon lowlands, and Atlantic Ocean. This "Andes-Amazon-Atlantic" (AAA) pathway is a complex hydroclimatic system linked by the regional water cycle through atmospheric circulation and continental hydrology. Here, we aim to articulate the AAA hydroclimate pathway as a foundational system for research, management, conservation, and governance of aquatic systems of the Amazon Basin. We identify and describe the AAA pathway as an interdependent, multidirectional, and multiscale hydroclimate system. We then present an assessment of recent (1981 to 2020) changes in the AAA pathway, primarily reflecting an acceleration in the rates of hydrologic fluxes (i.e., water cycle intensification). We discuss how the changing AAA pathway orchestrates and impacts social-ecological systems. We conclude with four recommendations for the sustainability of the AAA pathway in ongoing research, management, conservation, and governance.
ABSTRACT
As educators, we should not assume that students are progressing toward intended STEM careers simply because they have persisted and received a STEM degree. In addition to learning biology content and scientific skills, students need guidance in making optimal career choices. In this study, we present seven career development modules designed specifically to motivate students to consider their successes as scientists and to consider applying their biological knowledge and scientific skills to a range of biology careers. These modules highlight the value and the utility of a biology degree and are, therefore, designed to increase students' self-confidence as well as their science and biology identities. The career development modules presented here are easy to implement and, in our experience, encourage engagement and class discussions. Our analyses confirm that these modules collectively increase student science and biology identities, two predictors for entry into STEM careers.
