How Far-Right Populism Harms Ethnic Minorities’ Health: The Case Of The United States, Dina Rosenberg Jun 2025

How Far-Right Populism Harms Ethnic Minorities’ Health: The Case Of The United States, Dina Rosenberg

Working Papers Series

Public health is a political issue, and the health of ethnic minorities is a key component of it. We argue that far-right populism, whether grassroots or elitist, harms the health of immigrants and minorities. Anti-minority attitudes and policies—such as health chauvinism promoted by far-right populists—along with hate rhetoric and ensuing personal and institutional discrimination create a climate of hostility that negatively affects health outcomes in underprivileged communities. We hypothesize that immigrants and ethnic minorities living in such a climate are more likely to experience health problems and underutilize healthcare. To test this, we leverage the significant variation between U.S. states …

Prescribed Fire Leads A Pine Flatwoods Specialist Tree Frog To Seek Local Refugia, Ian Biazzo, Pedro F. Quintana-Ascencio Jun 2025

Prescribed Fire Leads A Pine Flatwoods Specialist Tree Frog To Seek Local Refugia, Ian Biazzo, Pedro F. Quintana-Ascencio

Faculty Publications

Pine savannas of the southeastern United States evolved with frequent low-intensity wildfires. Today, land managers use prescribed fires to restore this ecological process while also controlling vegetative fuel accumulation. Given the ubiquitous application of this management tool, studies should consider impacts on target and nontarget taxa in these systems. During fires, animal populations persist in the landscape when individuals emigrate to unburned areas or seek refugia within the burn zone; otherwise, they experience local extirpation. We examined the effect of prescribed fires on a pine flatwoods specialist frog, the pinewoods treefrog Dryophytes femoralis, in a frequently burned pine landscape. …
