Knight Center Researchers Share Work at International Conference

Three Knight Center for Environmental Journalism researchers presented their work at the Conference on Communication and the Environment, held June 23–27, 2025, at the University of Tasmania in Hobart, Australia.

Research Director Bruno Takahashi  presented the ongoing project, “The Discursive (De)construction of Oil Spills: A Case Study of Mediaciones in the Peruvian Amazon.” The project, in collaboration with doctoral student Iasmim Amiden dos Santos, combines in-depth interviews with journalists, Indigenous communicators and community members, with participant observation and media content analysis, to unpack how oil spills are framed and contested.

Takahashi also joined the panel “Publishing Environmental Communication: From Aggravations to Aspirations,” sharing insights from his experience as an editor and highlighting ways to make academic publishing more accessible to researchers in the Global South.

Amiden dos Santos also showcased her study, “Ecofeminist and Ecocentric Discourses in Brazilian Independent Media Coverage of the Pantanal and Cerrado.” Her discourse analysis revealed how two independent news outlets in Brazil broke from conventional journalism norms to center marginalized voices, reflecting ecofeminist, anti-capitalist and decolonial perspectives.

First-year MA student Julia Belden presented “A Killer Whale Tale: An Analysis of The Miami Herald’s Coverage of the Orca Tokitae from 1970 to 2023.” Her work traced how the newspaper’s coverage shifted over five decades—from entertainment and spectacle to animal welfare, business, and conflict—capturing evolving public attitudes toward a single, iconic animal.

Belden also participated in the conference’s pre- and post-events. The pre-conference brought together graduate students from around the world to share experiences and learn about academic scholarship from senior researchers. The post-conference was a Deep Ecology workshop that invited participants to deepen their connection with nature through guided reflection and immersive activities.

These presentations and activities highlight the Knight Center’s expanding role in global conversations on environmental journalism and its commitment to fostering research with international reach and impact.

 

Decreasing numbers of Gunnison’s prairie dogs in Arizona due to the plague

Standing at around 16 inches tall, the native North American rodent has been subject to significant population declines since the early 1900s.

At the Society of Environmental Journalists recent annual conference in Arizona, journalists were taught about the fluctuating numbers of prairie dogs, especially Gunnison’s prairie dogs.

There are many reasons for the decline in the number of prairie dogs, like hunting, but one factor stands out from the rest: the bubonic plague, said Emily Renn, a PhD student at Northern Arizona University’s School of Earth and Sustainability

“Throughout Arizona, Gunnison’s prairie dogs declined over 96% across their range,” Renn said.

However, even though they were petitioned for protection under the U.S. Fish and Wildlife Service, the agency determined that listing the prairie dog under the Endangered Species Act was not justified.

Historically, their range was much broader than today, but there still is hope, said Jim Devos, the Mexican wolf coordinator for the Arizona Game and Fish Department.

“We believe that with some of the conservation measures others are implementing, we anticipate if we can get on top of the plague issue, which is the single greatest challenge today, that we can get back to more robust prairie dogs,” said Devos. Continue reading

New age of safety measures for environmental journalists reporting from the Amazon

This is the 4th in a series of articles about reporting skills by Knight Center students who attended the 2025 Society of Environmental Journalists conference.

Reporters working in or focusing on the Amazon rainforest are forced to take extreme safety measures while doing so. That’s because their coverage threatens industries seeking to exploit  the region’s resources and populations.

At the 2025 conference of the Society of  Environmental Journalists in Tempe, Arizona, this topic was presented by representatives from the nonprofit organization Brazilian Association of Investigative Journalism (Abraji); security manager Valeria Oliveira and project coordinator Reinaldo Chaves.

The panel was hosted in two languages, Portuguese and English, and was part of an effort to answer why journalists in certain regions, like the Amazon, are put into such dangerous positions and how those threats are combated in the field.

Attendees were guided through a presentation on how Abraji funds, trains and mentors reporters investigating environmental crimes in the Amazon, leading to eight successful investigations thus far. Their organization advocates transparency and prioritizes journalists’ ability to have creative freedom to deliver the stories they want, but reinforces that physical security is the most important aspect of their work.

Latin America is the most dangerous place in the world to be an environmental journalist, according to a 2022 study by the international organization Committee to Protect Journalists.. The Amazon region is under particular stress, according to Reuters. In the past decade, over 200 incidents against journalists, such as threats, kidnappings and murders, have been documented.

Knight Center partners team up to report on threats to Great Lakes whitefish

Clara Lincolnhol

Environmental journalism intern Clara Lincolnhol of WKAR radio and environmental journalist Kelly House of Bridge Michigan recently discussed threats to Great Lakes whitefish populations in a public radio broadcast.

Lincolnhol’s internship is underwritten by the Knight Center for Environmental Journalism. House, a Knight Center alum, reports for Bridge Michigan, which partners with the Knight Center as part of the Mott Foundation’s Great Lakes News Collaborative.

Here are the highlights and a transcript of Lincolnhol’s interview with House.

Great Lakes whitefish populations could soon disappear for good

By Clara Lincolnhol

Whitefish are a beloved and iconic Michigan species that have been a staple of the state’s cuisine for centuries.

But their numbers have dwindled drastically recently leaving some worried that the fish will no longer populate the lower Great Lakes.

Kelly House

WKAR’s Clara Lincolnhol spoke with Bridge Michigan reporter Kelly House who recently reported on why the fish population is declining and whitefish’s cultural and economic significance to Michiganders.

On how invasive quagga mussels are threatening whitefish

Scientists have been responding to the threat by trying to find some way to suppress mussel populations in the Great Lakes. They now cover essentially every inch of the lakebed, and the problem is that they’re filter feeders, and they have filtered away the plankton and nutrients that other species in the Great Lakes really rely upon for food. So, these baby whitefish are born. The only thing they eat in their first days of life is phytoplankton, and those plankton are now nowhere to be found, so these babies are essentially starving to death before they ever have the opportunity to grow.
