Host-Pathogen Interactions In A Changing World: Microbes, Mucosal Defenses, And Multiple Hosts, Brandon C. Labumbard Dec 2022

Host-Pathogen Interactions In A Changing World: Microbes, Mucosal Defenses, And Multiple Hosts, Brandon C. Labumbard

Graduate Doctoral Dissertations

As fungal diseases continue to emerge, research increasingly focuses on host-microbiome interactions and links to disease. Certain skin-associated microbes may benefit hosts by protecting them from invading pathogens. Seasonal changes in the host environment can also result in shifts in the microbial community and pathogen virulence – potentially influencing disease dynamics. I investigated how cutaneous microbial communities differ across hosts, seasons, and Batrachochytrium dendrobatidis (Bd) infection status by sequencing the microbial communities of 1,100 leopard frogs at five locations across the US. Percent anti-Bd function varied seasonally and with Bd infection status. Bacterial communities also varied across locations and time. …


Participatory Science In Boston Harbor: Bridging Research And Outreach, Anne E. O'Connell Aug 2022

Participatory Science In Boston Harbor: Bridging Research And Outreach, Anne E. O'Connell

Graduate Masters Theses

Participatory science programs are becoming effective mechanisms to provide members of the public opportunities to be involved in scientific research worldwide. In the city of Boston, coastal resilience research is of particular interest to researchers, policy makers, and members of the public due to the threat of up to two meters of sea level rise by the year 2100. As part of the outreach and education initiative at the Stone Living Lab, community members were trained to use the Emery method of beach profiling and conducted measurements at twelve different sites around Boston harbor. The sites were visited during the …


Understanding Environmental Justice Instruction In Higher Education: Activist Epistemic Orientations And A Continuum Of Community Engaged Curricular And Pedagogical Practice, Christopher James Rabe May 2022

Understanding Environmental Justice Instruction In Higher Education: Activist Epistemic Orientations And A Continuum Of Community Engaged Curricular And Pedagogical Practice, Christopher James Rabe

Graduate Doctoral Dissertations

Starting in the early 1980’s, the environmental justice (EJ) movement was critical in drawing much needed attention to how communities of color, low-income groups, Indigenous peoples, and other marginalized groups have experienced a disproportionate burden of environmental and ecological harms. The EJ movement sparked the birth of the EJ field of study. While originally focused on quantitative and distributional understandings of toxic waste in communities of color, the EJ field of study has since expanded to comprise community-based methodologies and new ways to understand justice, including participatory, recognition, and transformational approaches. The EJ field now represents multiple areas such as …


Damming Sustainability: How Social And Environmental Networks Influence The Construction And Management Of Large Dams In The Amazon Basin, V. Miranda Chase May 2022

Damming Sustainability: How Social And Environmental Networks Influence The Construction And Management Of Large Dams In The Amazon Basin, V. Miranda Chase

Graduate Doctoral Dissertations

,p>Dams are powerful structures that engender a flood of controversies. These projects face great criticism from numerous groups, many of whom succeed in influencing such enterprises. This research is an in-depth study on dam-related social and environmental movements in the Amazon: how they are created and internally organized; how members share information and resources, how they identify alternatives; and how they design strategies and implement agendas. Social movements include, but are not limited to, domestic and international nongovernmental organizations (NGOs), academic researchers, journalists, religious organizations, grassroots associations, and large private foundations. They create formal or informal coalitions and design …
