For much of the past century, the invasive pink bollworm wreaked havoc in the southwestern United States and northern Mexico. A multifaceted strategy eradicated the pest from cotton-producing areas of the region according to a new study led by Regents professor, UArizona Entomology department head, and BIO5 member, Dr. Bruce Tabashnik. According to the study, the eradication program saved U.S. cotton growers $192 million from 2014 to 2019. Through environmentally friendly approaches, it also helped to reduce insecticides sprayed against all cotton pests by 82% and prevented the application of over a million pounds of insecticides per year in Arizona.

A $3 million grant from the National Science Foundation will support University of Arizona graduate students looking to work across scientific disciplines to take on the world's grand challenges, from global climate change to sustainable food production. The grant was awarded to researchers with the UArizona Ecosystem Genomics Initiative, which brings together researchers from a wide range of scientific fields to design new models to inform global climate policy, identify genes and genomic interactions that enhance crop yield, and prepare graduate students to join the national workforce in fields such as ecosystem management, medical genetics and food security.

Dr. Brian Enquist teamed up with Nirav Merchant, CyVerse co-principal investigator and director of UArizona Data Science Institute, to lead an interdisciplinary collaboration of the nation's scientists aiming to harness the power of big data and cyberinfrastructure to predict global biodiversity changes under different climate outcome scenarios. The project was funded this year at $2.5 million under the National Science Foundation's Harnessing the Data Revolution program, with just over $966,000 awarded to UArizona. The grant stemmed from work done by the Bridging Biodiversity and Conservation Science group, a new interdisciplinary initiative at the University of Arizona.

The world’s hottest rainforest is located not in the Amazon or anywhere else you might expect, but inside Biosphere 2, the experimental scientific research facility in the desert outside Tucson, Arizona. A recent study of tropical trees planted there in the early 1990s reported a surprising result: They have withstood temperatures higher than any likely to be experienced by tropical forests this century.

Dr. Eliot Herman, a professor of plant sciences, has dedicated his career studying why plants, such as the soybean plant, trigger allergic reactions and how to reduce the likelihood of them being triggered. By crossing a non-allergenic strain of soybeans with more commonly grown soybeans, Herman and his team were able to create a new, productive plant with reduced allergic sensitivity.

Tropical forests may be more resilient to predicted temperature increases under global climate change than previously thought, a study published in the journal Nature Plants suggests. The group led by Dr. Scott Saleska, UArizona professor in the Department of Ecology and Evolutionary Biology, studied data from the rainforest habitat at UArizona's Biosphere 2 and compared them to measurements taken at natural tropical forest sites. The results could help make climate prediction models more accurate.

The quest to protect Arizona’s quality of life under the scorch of record breaking heat, drought, and increasing wildfires is a constant chore. A slate of experts in Tucson, including Biosphere 2 director and BIO5 member Dr. Joaquin Ruiz, offered up recommendations on how Arizona can rise above the heat to keep the economy and the environment thriving.

Dr. Bruce Tabashnik, head of the Department of Entomology and BIO5 member, has won the Plant-Insect Ecosystems Lifetime Achievement Award in Entomology from the Entomological Society of America. Dr. Tabashnik's research has provided fundamental knowledge about insects for enhancing agricultural sustainability and reducing the use of harmful insecticides.

While many of us have been working from home this summer, several species of insects and plants have been acting out fascinating plays of interactions and mutual interdependence across campus. Dr. Judith Bronstein, UArizona Distinguished Professor of Ecology and Evolutionary Biology and BIO5 member, discusses what we can learn from these mutualistic interactions and how she studies insect dynamics.

Dr. Judith Brown, UArizona evolutionary ecologist and BIO5 member, shares the importance of the partnership between ants and wildflowers in preserving ecosystems, especially forests that could be disturbed by human activity. This relationship was reported during the annual meeting of the Ecological Society of America, where researchers discussed the seed dispersion that ants complete.

A new paper, co-authored by UArizona associate professor of Molecular & Cellular Biology and BIO5 member Dr. Solange Duhamel, reports that salamander eggs compete with the algae that lives inside its eggs to assimilate carbon from their surroundings – a finding that could inform similar processes in the dark ocean.
 
NEWS
Plants and animals often engage in symbiotic relationships that benefit both organisms. Scientists used to believe that the salamander eggs and algae may be helping one another by exchanging sugar molecules produced through photosynthesis – but a series of laboratory experiments by Dr. Solange Duhamel and others showed that this was not the case. Instead, salamander embryos may be able to develop without the need for this exchange.

Nicknamed the “billion-dollar beetle” for its enormous economic costs to growers in the United States each year, the western corn rootworm is one of the most devastating pests farmers face. BIO5 members Drs. Bruce Tabashnik & Yves Carriere share their research on how crop rotation and diversification can help combat the rootworm’s resistance toward certain crops.

The Arizona Board of Regents today confirmed the appointments of five UArizona faculty members, including BIO5 members Drs. Roberta Diaz Brinton and Judith Brown, as Regents Professors. The title of 'Regents Professor' is reserved for full professors whose exceptional achievements merit national and international distinction.

When your tomato plants won’t bear fruit during the dog days of summer, a team of Wake Forest researchers led by Dr. Gloria Muday and including Dr. Ravishankar Palanivelu of the University of Arizona will be in the lab, trying to find a plant that thrives despite the heat. A $3 million grant from the National Science Foundation will help determine why most tomato plants fail to pollinate with the goal of producing more heat-tolerant crops.

As the human population grows to more than 10 billion in the next 30 years, plant breeders must do everything possible to create crops that are highly productive and nutritious with minimal environmental footprints. Rice will play a critical role in meeting this demand to feed the growing population, so understanding the genetic diversity of these crops is essential. To meet this demand, Drs. David Kudrna and Rod Wing examined the genomes from representatives of 12 of 15 subpopulations of cultivated Asian rice to detect virtually all variation that exists in the pan-genome of cultivated Asian rice.
