In a new study published in PLOS Genetics, Decker and his team have uncovered evidence showing that cattle are losing important environmental adaptations, losses the researchers attribute to a lack of genetic information available to farmers.

Cattle Losing Adaptations to Environmental Stressors, MU Researchers Find

As a fourth-generation cattle farmer, Jared Decker knows that cattle suffer from health and productivity issues when they are taken from one environment–which the herd has spent generations adapting to–to a place with a different climate, a different elevation or even different grass. But as a researcher at the University of Missouri, Decker also sees an opportunity to use science to solve this problem, both to improve the welfare of cattle and to plug a leak in a nearly $50 billion industry in the U.S. “When I joined MU in 2013, I moved cattle from a family farm in New…

Unconscious Biases can Drive Foodborne Illness Outbreaks, MU Researchers Find

In the midst of a pandemic that has claimed more than 2 million lives worldwide and disrupted nearly every facet of society since it appeared more than a year ago, understanding the factors that create and facilitate disease outbreaks is more important than ever. Now, researchers at the University of Missouri have determined that cognitive biases — patterns of errors in thinking that affect judgments and behaviors, often unconsciously — can help create and worsen foodborne disease outbreaks. Harvey James believes studying unconscious biases can help researchers learn how outbreaks are born. “Unethical behavior isn’t always…

Breakthrough Could Lead to Early Detection of Pregnancy Complications

Constantine Simintiras and his colleagues in Thomas Spencer’s lab have found a non-invasive way to study fluid produced in the uterus during pregnancy. The quest to create safer, more successful pregnancies is one of the top goals of modern science. While pregnancy is better understood today than ever before, with improvements in technology helping to lower the risk of negative outcomes, there is much researchers still don’t know about a vital part of the pregnancy process: uterine fluid. Secreted by glands in the uterus during pregnancy, uterine fluid is believed to play an important role in…

Piecing Together the Puzzles of Bird Genomes

In 2003, scientists finished sequencing the entire human genome, paving the way for new discoveries about genetic disorders and the numerous ways that genes influence behavior, health and other traits. But the importance of a complete genome for scientific reference is not limited to humans — researchers are now engaged in an all-out push to assemble the genomes of vertebrates across the animal kingdom, racing to unlock the secrets behind the genetic origins of unusual behaviors and the evolution of devastating diseases. In a flagship paper recently featured on the cover of Nature, more than 100 researchers worldwide contributed groundbreaking research to…

A Burning Passion for the Good Kind of Forest Fire

Michael Stambaugh wants people to know that fire is not always bad. He knows that to some people, this is like saying water is dry, and after 20 years as a researcher at the University of Missouri, he’s still trying to show the good that can come from one of nature’s most powerful forces. “Fire is a historical legacy,” said Stambaugh, who is currently an associate research professor in MU’s College of Agriculture, Food and Natural Resources (CAFNR). “We, as people, are linked to it for our survival.” Stambaugh inspects the stump of an old white pine…

A SNAPSHOT of Wildlife Patterns Nationwide

Wildlife behavioral patterns have been tracked by researchers across the United States for years. While many individual research studies have been done on this topic, a snapshot of the United States as whole, has not. Summer LaRose, research wildlife biologist at the University of Missouri (MU) in College of Agriculture, Food and Natural Resources (CAFNR), participated in a nationwide study tracking wildlife pattern. The paper was titled SNAPSHOT USA 2019: A Coordinated national Camera Trap Survey of the United States. In total, over 83 species of mammals and 17 bird species were identified. The top 10 most common species identified…

Studying Oxygen Levels in Lakes Around the World

A recent study shows that oxygen levels in temperate lakes around the world are declining rapidly, a trend that is largely driven by warming temperatures that threatens freshwater biodiversity and drinking water quality. Rebecca North, assistant professor of limnology in the University of Missouri (MU) College of Agriculture, Food and Natural Resources (CAFNR), took part in a world-wide study, which used data from over 400 lakes around the world, looking at oxygen levels. Of the 400 lakes studied, data from 30 reservoirs in the state of Missouri were used. The paper, titled Widespread Deoxygenation of Temperate Lakes, was recently…
