Virtually Viral Hangouts: Reflections on the role of community during crisis

In this essay, I reflect on two key aspects of my membership in the online community known as Virtually Viral Hangouts (VVH). First, I reflect on how membership in this group helped me professionally, providing important, in-time instruction as I learned to make the switch from in-person to remote learning in the early days of Covid-19. Next, I reflect on how membership in this group helped me personally, as I struggled to find my identity as a teacher through a computer screen. I conclude by reflecting upon what it means to be a member of a community and why such membership matters in higher education and beyond

Global status and conservation potential of reef sharks

Decades of overexploitation have devastated shark populations, leaving considerable doubt as to their ecological status1,2. Yet much of what is known about sharks has been inferred from catch records in industrial fisheries, whereas far less information is available about sharks that live in coastal habitats3. Here we address this knowledge gap using data from more than 15,000 standardized baited remote underwater video stations that were deployed on 371 reefs in 58 nations to estimate the conservation status of reef sharks globally. Our results reveal the profound impact that fishing has had on reef shark populations: we observed no sharks on almost 20% of the surveyed reefs. Reef sharks were almost completely absent from reefs in several nations, and shark depletion was strongly related to socio-economic conditions such as the size and proximity of the nearest market, poor governance and the density of the human population. However, opportunities for the conservation of reef sharks remain: shark sanctuaries, closed areas, catch limits and an absence of gillnets and longlines were associated with a substantially higher relative abundance of reef sharks. These results reveal several policy pathways for the restoration and management of reef shark populations, from direct top-down management of fishing to indirect improvement of governance conditions. Reef shark populations will only have a high chance of recovery by engaging key socio-economic aspects of tropical fisheries
