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…

A Humbling Opportunity

As an alum of the University of Missouri, Bryon Wiegand has worked at his alma mater since 2007, in the College of Agriculture, Food and Natural Resources (CAFNR) Division of Animal Sciences. Wiegand first joined Mizzou as an associate professor and has served as a professor in the division since 2015, with assignments in teaching, research and Extension. He was named the associate division director in 2019 – and was recently tapped as the director of the Division of Animal Sciences. The new role is effective Saturday, May 15. “As a Mizzou alum, I am humbled to have the opportunity…
The United States Department of Agriculture’s (USDA) National Institute of Food and Agriculture (NIFA) awarded nearly $11 million in funding for grants related to enhancing animal reproduction, and improving the welfare and well-being of agriculture animals. Researchers in the University of Missouri College of Agriculture, Food and Natural Resources (CAFNR) Division of Animal Sciences earned three of the 15 grants related to enhancing animal reproduction. MU was awarded just more than $1 million of the $6.72 million total investment in animal reproduction.

Nudging Landowners and Tenants Toward Environmental and Social Stewardship

Ray Massey, Extension professor, and Michelle Segovia, assistant professor, both faculty of agricultural and applied economics in the Division of Applied Social Sciences, recently received a grant from USDA’s National Institute of Food and Agriculture (NIFA). The grant is for $498,833 and is titled, “Nudging Landowners and Tenants Toward Environmental and Social Stewardship.” The grant was part of a recent $11.5-million USDA research investment to help ensure America’s small and medium-sized farms become more profitable and improve the quality of life in American farm communities. “The ultimate goal of our project is to promote societal goals by fostering new leasing…
The Precision and Automated Agriculture Lab (PAAL) in the CAFNR Division of Food Systems and Bioengineering recently teamed up with researchers in the CAFNR Division of Plant Sciences to study yield estimation of soybean breeding lines under drought stress using unmanned aerial vehicle-based imagery and convolutional neural network. Their work resulted in a paper published by Biosystems Engineering. Pictured is Jing Zhou flying a drone at the Fisher Delta Research Center. Photo courtesy of Jing Zhou.

A Different Perspective

High yield potential is often the top trait crop breeders look at, as higher yielding crops can lead to more money in a producer’s pocket. Researchers in the University of Missouri College of Agriculture, Food and Natural Resources (CAFNR) conduct a variety of trait-related trials through various breeding programs. The Precision and Automated Agriculture Lab (PAAL) in the CAFNR Division of Food Systems and Bioengineering recently teamed up with researchers in the CAFNR Division of Plant Sciences to study yield estimation of soybean breeding lines under drought stress using unmanned aerial vehicle-based imagery and convolutional neural network.
