Mitochondrial DNA Inheritance in Bivalves: A Comparative Study Involving the Unique System of Doubly Uniparental Inheritance

A comparative study of Doubly Uniparental Inheritance (DUI) in the bivalve mollusks Mytilus edulis and Geukensia demissa has yielded unanticipated results. Around the world, it has been reported that members of the taxonomic family Mytilidae (along with the families of Unionidae and Veneridae) consistently exhibit DUI. However, the hard-to-place Geukensia demissa, which is a member of this family, has had varying reports of its DUI status. Most reports involving G. demissa vary with the location in which it is being studied, which prompts more questions than it answers. Due to many months of unsuccessful DNA purification attempts, sequencing and an actual determination and subsequent comparison of DUI within these two species failed to occur. What successfully occurred in this study was the inducement of reproduction in Geukensia demissa in tanks in a laboratory, and a successful purification of DNA from G. demissa followed by amplification of mtDNA using species-specific primers

“I Alone Can’t Stop the Spread”: Mid-Level Conduct Professionals Sensemaking Through COVID-19

The purpose of this qualitative study is to explore how mid-level student conduct professionals (SCPs) made meaning of their professional and mid-level leadership experiences during their institutions’ immediate responses to the COVID-19 pandemic. This study draws on sensemaking as a theoretical lens and literature related to mid-level professionals and student conduct practice to ground its inquiry. Interview data was collected and analyzed from four senior-level student conduct professionals within a single State within the Southern Association of Colleges and Schools Commission on Colleges (SACSCOC) accreditation region. Findings center on three key themes voiced by the participants: the importance of maintaining operational processes, feelings of middleness, and reflections on student and personal wellbeing. Discussion and implications for professionals and postsecondary organizations confronting the short- and long-term effects of the COVID-19 pandemic are offered. Here, we highlight the valuable roles student conduct professionals play within postsecondary organizational life and the need for greater attention to these practitioners in both research and practice
