Bioscience Talks

For this episode, we're joined by Dr. Judith Weis of Rutgers University to discuss her new book, Polluting Textiles: The Problem with Microfibres. Listen to Dr. Weis's In Their Own Words oral history interview. A description of the book follows:This book examines the critical issue of environmental pollutants produced by the textiles industry.Comprised of contributions from environmental scientists and materials and textiles scientists, this edited volume addresses the environmental impact of microplastics, with a particular focus on microfibres released by textiles into marine and freshwater environments. The chapters in Part I offer environmental perspectives focusing on the measurement of microplastics in the environment, their ingestion by small plankton and larger filter feeders, the effects of consuming microplastics, and the role of microplastics as a vector for transferring toxic contaminants in food webs. Written by environmental and material scientists, the chapters in Part II present potential solu

For this episode, we're joined by Thyaga Nandagopal, Division Director for the Division of Innovation and Technology Ecosystems, in the newly launched TIP Directorate at NSF. He discusses the directorate's programs, priorities, and future plans.

COVID-19 has been the first pandemic that has taken place alongside the interconnectivity of the Internet. Consequently, the spread of ideas and information about the disease has been unprecedented—but not always accurate. One of the widely circulated headlines was that of the relationship between land change and the spillover of diseases from wildlife to humans. Writing in BioScience, Andre D. Mader of the Institute for Global Environmental Strategies and colleagues survey primary and secondary literature, as well as webpage content on the subject of land change and zoonotic disease risk. Based on the patterns picked up from this literature and media coverage, Mader and colleagues describe what amounts to a case study in improper science communication and its possible consequences. Dr. Mader joins us on this episode of BioScience Talks to discuss his article in depth. This episode can also be found on Mader's podcast, The Case for Conservation.Read more about the article: According to the authors, media mess

As the effects of climate change mount, ecosystem restoration in the US West has garnered significant public attention, bolstered by President Joe Biden's America the Beautiful plan to conserve 30% of US land and water by 2030. Writing in BioScience, William J. Ripple and 19 colleagues follow up on the Biden plan with a proposal for a "Western Rewilding Network," comprising 11 large reserve areas already owned by the federal government. The authors advocate for the cessation of livestock grazing on some federal lands, coupled with the restoration of two keystone species: the gray wolf and the North American beaver. For this episode, we're joined by Mike Phillips of the Turner Endangered Species Fund, one of the Viewpoint's coauthors.

As global warming accelerates, it is increasingly clear that climate change is affecting our planet on every scale, from global shifts in weather patterns to local ecosystem changes. In a special section in BioScience, a group of authors hailing from the US National Science Foundation’s Long Term Ecological Research (LTER) Network synthesize insights from 40 years of long-term ecological research on how ecosystems are responding to climate change. For today's episode, we're joined by the authors of that special section's lead article, Julia Jones, Professor of Geography at Oregon state University and an investigator at the Andrews Forest Long-Term Ecological Research site, and Charles Driscoll, Professor in the Department of Civil and Environmental Engineering at Syracuse University and an investigator at the Hubbard Brook Long-Term Ecological Research site.According to the special section authors, although the variety of ecosystems have some responses in common, most ecosystem responses to climate change are

In this episode, we're joined by Alexandre C. Siqueira, a postdoctoral fellow at James Cook University in Townsville, Australia, where he works in the lab of Professor David Bellwood. He joined us to talk about his recent BioScience article on reef fish evolution, and how we're learning more about that topic from some recent findings in Mayan temples. The article's abstract follows.During the excavation of Mayan tombs, little did the archaeologists know that the fossils they discovered in the tomb stones would fundamentally alter our understanding of the earliest origins of coral reef fishes. Located just 500 kilometers from the point where an asteroid impact reconfigured the world's biological systems 66 million years ago, we find the earliest origins of three typical reef fish groups. Their presence in Mexico just 3 million years after this impact finally reconciles the conflict between the fossil and phylogenetic evidence for the earliest origins of reef fishes. The incorporation of these fossils into a gl

In Their Own Words chronicles the stories of scientists who have made great contributions to their fields. These short histories provide our readers a way to learn from and share their experiences. We will publish the results of these conversations in the pages of BioScience and on our podcast, BioScience Talks. This history is with Daniel Simberloff, who is the Gore-Hunger Professor of Environmental Studies in Department of Ecology and Evolutionary Biology, at the University of Tennessee, in Knoxville, in the United States.Note: Both the text and audio versions have been edited for clarity and length.

Throughout the COVID-19 pandemic, public health officials and others have used concepts such as "waves" to convey information about the spread of disease. In this episode, we're joined by Dr. Louise Archer, Postdoctoral Fellow in the Laboratory of Quantitative Global Change Ecology at the University of Toronto, Scarborough, who wrote in BioScience about disease analogies. She and her coauthors found that some analogies are more useful than others -- for instance, wave analogies may instill a sense of inevitability and depress disease mitigation, whereas firefighting analogies may encourage action while simultaneously contributing to a more nuanced understanding of disease dynamics. 

We're joined by Dr. Pam McElwee, Professor of Human Ecology at Rutgers University, and Dr. Sarah Diamond, Associate Professor of Biology at Case Western Reserve University. They were here to discuss their recent BioScience article, Governing for Transformative Change across the Biodiversity–Climate–Society Nexus, which describes principles for addressing global environmental crises.The abstract of their article follows.Transformative governance is key to addressing the global environmental crisis. We explore how transformative governance of complex biodiversity–climate–society interactions can be achieved, drawing on the first joint report between the Intergovernmental Panel on Climate Change and the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services to reflect on the current opportunities, barriers, and challenges for transformative governance. We identify principles for transformative governance under a biodiversity–climate–society nexus frame using four case studies: forest ec

In this episode, we're joined by Dr. Robert Montgomery, Associate Professor of Biodiversity and Sustainability, Senior Research Fellow in Lady Margaret Hall College, and Senior Researcher in the Wildlife Conservation Research Unit, at Oxford University. He's here to talk about his recent BioScience article, Integrating Social Justice into Higher Education Conservation Science. The abstract of the article follows.Because biodiversity loss has largely been attributed to human actions, people, particularly those in the Global South, are regularly depicted as threats to conservation. This context has facilitated rapid growth in green militarization, with fierce crackdowns against real or perceived environmental offenders. We designed an undergraduate course to assess student perspectives on biodiversity conservation and social justice and positioned those students to contribute to a human heritage-centered conservation (HHCC) initiative situated in Uganda. We evaluated changes in perspectives using pre- and postc

Thomas Larsen and Patrick Roberts of the Max Planck Institute of the Science of Human History join us to discuss how we can learn about early hominins diets using stable isotope analysis. The abstract of their BioScience article follows.Stable isotope analysis of teeth and bones is regularly applied by archeologists and paleoanthropologists seeking to reconstruct diets, ecologies, and environments of past hominin populations. Moving beyond the now prevalent study of stable isotope ratios from bulk materials, researchers are increasingly turning to stable isotope ratios of individual amino acids to obtain more detailed and robust insights into trophic level and resource use. In the present article, we provide a guide on how to best use amino acid stable isotope ratios to determine hominin dietary behaviors and ecologies, past and present. We highlight existing uncertainties of interpretation and the methodological developments required to ensure good practice. In doing so, we hope to make this promising approa

In this episode, we're joined by Liam Zarri, PhD student at Cornell University, and Dr. Eric Palkovacs, Professor of Ecology and Evolutionary Biology at the University of California, Santa Cruz. They discuss their recent BioScience article on evolutionary effects of dams and other anthropogenic water barriers, such as culverts, on riverine fishes. The impacts they highlight include rapid evolution affecting behavior, migration, behavior, temperature tolerance, and body type. Damming waterways can also lead to reductions in genetic diversity, with possibly harmful effects for fish populations.

In this episode, we're joined by Kim Novick, Associate Professor in the O'Neill School of Public and Environmental Affairs at Indiana University, Richard Phillips, Professor in the Department of Biology at Indiana University, and Justin Maxwell, Associate Professor, Department of Geography at Indiana University. They were here to talk about their recent article in BioScience on the topic of drought resilience in eastern oaks, an issue of ever more urgent importance given the changing climate. 

The positive effects of scientist engagement with the general public are well documented, but most investigations have focused on the benefits to the public rather than on those performing engagement activities. Writing in BioScience, Nalini Nadkarni of the University of Utah and colleagues "reverse the lens" on public engagement with science, discovering numerous benefits for scientists involved in these efforts.The authors distributed pre- and post-event surveys to individuals who are incarcerated in a state prison and a county jail as part of the Initiative to Bring Science Programs to the Incarcerated (INSPIRE) program, through which scientists present informal scientific lectures in carceral settings. This sort of engagement is particularly important, say the authors, given the growing emphasis among funding agencies and in academia on broadening the reach of science to include scientifically underserved groups.The results of the surveys were striking, with 100% of the scientist participants reporting th

While numerous studies have described the funding discrepancies faced by scientists at minority-serving institutions (MSIs), there is a relative paucity of information available about MSI-based scientists' participation in grant review, the process used by research funders to allocate their budgets. A new article from the American Institute of Biological Sciences (AIBS) sheds further light on grant review and the factors that underlie scientists' ability to participate in it. Writing in the journal BioScience, AIBS scientists Stephen A. Gallo, Joanne H. Sullivan, and DaJoie R. Croslan describe the results of a survey disseminated to thousands of MSI-based scientists aimed at elucidating discrepancies in grant review participation between MSI-based scientists and those who work at traditionally White institutions (TWIs). The survey questions addressed a range of topics, including the scientists' recent funding and peer review experiences, as well as their motivations for engaging in the grant review process.  

Natural resource managers worldwide face a growing challenge: Global change increasingly propels ecosystems on strong trajectories toward irreversible ecological transformations. As once-familiar historical ecological conditions fade, managers need new approaches to guide decision-making. In a special section in BioScience, three dozen authors, led by National Park Service (NPS) ecologist Gregor Schuurman and US Geological Survey social scientist Amanda Cravens, describe the Resist–Accept–Direct (RAD) framework, designed for and by managers. The collection of articles is focused on understanding and responding to the challenges of stewarding ecological systems in a time of intensifying global change.            According to the section authors, the RAD framework gives managers three general pathways for responding to change: They can take actions to resist the change, they can accept it, or they can try to direct the change to produce desirable outcomes. The NPS has honed the RAD framework with an expanding c

The American institute of Biological Sciences, publisher of the BioScience Talks podcast, mourns the loss of visionary ecologist Thomas E. Lovejoy III. Dr. Lovejoy was the AIBS President in 1994. In 2012, he received the AIBS Outstanding Service Award, an award given annually in recognition of individuals’ and organizations’ noteworthy service to the biological sciences. Earlier this year, he joined us for an episode of our oral history series, In Their Own Words, which we republish here in memoriam. A version of this interview was also published in BioScience. Lovejoy died on December 25, 2021 in McLean, Virginia. He was 80.

In this episode of BioScience Talks, we're joined by Dr. Michael Lesser, Professor Emeritus at the University of New Hampshire. He's here to talk about his recent BioScience article, which details the ways that coral is affected by nutrients, climate change, and other stressors— and what those interconnected stressors mean for the future of reefs.

The task of training an effective cadre of biodiversity scientists has grown more challenging in recent years, as foundational skills and knowledge in organismal biology have increasingly required complementary data skills and knowledge. Writing in BioScience, Dr. Anna K. Monfils, of Central Michigan University, and colleagues identify one way to address this training conundrum: biodiversity collections. Biodiversity collections operate at the nexus of foundational biological practice and contemporary data science, a product of their role as curator of not only specimens themselves but also the specimens' associated data and network of data resources (referred to as the "extended specimen").            The authors describe a module that leverages this feature of biodiversity collections to produce a holistic student learning experience. The module, “Connecting students to citizen science and curated collections," was designed by the authors with six learning goals in mind, ranging from plant specimen collecti

In this episode of BioScience Talks, we're joined by Liz Browne, who has bachelor of science degree with honors from the University of Tasmania, and Scott Carver, disease ecologist at the University of Tasmania. They discuss the pathogen transmission, and in particular, the way that Sarcoptes scabiei, the mite responsible for mange, passes between members of different species, as well as the implications for epidemiology generally.
