    Laconia Sun: UNH Researchers Study Effects of Warmer, Snow-Free Winters

     New England’s warmer, snow-free winters may increase carbon dioxide losses in forests, where deciduous trees can’t take advantage of warm temperatures before their leaves emerge. However, farms cultivating grasses have a greater potential to start growing in the winter “dormant season,” perhaps partially offsetting the increasing winter carbon losses from forests, according to new research from the University of New Hampshire.

    Union Leader: UNH scientists join effort to identify most common weeds

    Scientists sampled weed seedbanks and measured soil physical and chemical characteristics on 77 organic farms across the region. They found temperature-related variables such as latitude, longitude, and mean maximum and minimum temperature were the strongest and most consistent correlates with weed seedbank composition, the news release states.

    Morning Ag Clips: Most prevalent weeds on organic vegetable farms

    This research was funded by the Northern New England Collaborative Research Funding Program, a partnership of the Maine Agricultural and Forest Experiment Station, New Hampshire Agricultural Experiment Station, and the Vermont Agricultural Experiment Station. The three station directors initiated the program with a goal to catalyze coordinated research on high-priority needs for the Northern New England region in experiment station mission areas, of significant importance across the three states. A second objective was to incentivize faculty at the three institutions to explore opportunities for ongoing cross-institutional research synergies.

    NHPR: Warmer Winters Negatively Impact Tourism and Forest Health

    In recent years, unreliable snow cover and wild temperature swings have caused headaches for our winter recreation industry, and all those who love to ski, ice-fish, or snowmobile.  But the impacts go beyond disappointment: there are animal and forest health affects as well, including the beloved Sugar maple.

    Fosters: UNH scientists help ID emerging, problematic weeds

    “We are living in a period of rapid and to some extent unpredictable environmental change, brought about by a variety of natural and human-mediated factors, including climate change, production practices, technological advances, and others. The purpose of this project was to establish a baseline assessment of the weed problems facing organic vegetable growers in the Northern New England region as a basis for detecting and predicting the evolutionary emergence of new, problematic weeds,” said New Hampshire Agricultural Experiment Station researcher Dr. Tom Davis, professor of genetics at the University of New Hampshire.

    Northern New England Scientists Identify Most Prevalent Weeds on Region’s Organic Vegetable Farms

    Scientists from Maine, New Hampshire, and Vermont have completed the first comprehensive assessment of weeds found on organic vegetable farms in Northern New England. The collaborative, three-state study is an important first step in providing a baseline for organic growers who could face challenges providing locally grown produce because of new, problematic weeds emerging due to environmental change.

    Union Leader: UNH researchers study effect of warmer, snowless winters

    New England’s warmer, snow-free winters may increase carbon dioxide losses in forests, where deciduous trees can’t take advantage of warm temperatures before their leaves emerge, according to University of New Hampshire researchers.

    Morning Ag Clips: Impact of warmer, snow-free winters

    “Changes in winter climate, such as warmer air temperatures and less snow cover, can influence plant and soils in the following growing season. A better understanding of how winter weather affects ecosystems will help us predict whether our ecosystems will exacerbate or mitigate climate change by taking up or removing carbon dioxide from the atmosphere.” -- Rebecca Sanders-DeMott

    NHPR: UNH Climate Research: Less Snow Hurts Economies & Environment

    New studies say a decrease in snow days as the climate changes is taking an economic toll on states like New Hampshire—as well as an environmental one.

    Warmer, Snow-Free Winters May Increase Carbon Dioxide Losses in Forests, Gains on Farms

    Morning Ag Clips: Fungal disease a concern for small grain growers

    Stem rust is one of the most feared agricultural diseases in the world, infecting wheat and other cereal crops. The fungal pathogen is capable of severe epidemics, thus presenting a threat to the global food supply. In New England, the disease is a concern in light of the region’s re-emerging small grain industry.

    Concord Monitor: The largest plant eradication effort in U.S. history tried to halt stem rust; UNH is working on it, too

    Scientists with the New Hampshire Agricultural Experiment Station at the University of New Hampshire are trying to understand the potential risk of the disease spreading and, perhaps even more importantly, evolving greater virulence in the region. Long term, they also hope to contribute to a genetic solution that reduces global yield losses to the disease.

    NHPR: EPA Chief Signals Push To Declare Wood Energy Carbon-Neutral On N.H. Visit

    NHAES researcher Dr. John Gunn says the polluting effects of burning wood are complex, and hinge on the kind and amount of material harvested, how it’s used, and what fuel it replaces. "If you're talking about, truly, residues from sawmills or the tops and limbs that were left over from harvest anyway, those have very good greenhouse gas emissions profiles compared to other scenarios where you're harvesting whole trees specifically for biomass energy uses, and those trees could have remained standing. That all matters in terms of the outcome, in terms of whether or not making energy from wood is better for the atmosphere than making energy from a fossil fuel.”

    Morning Ag Clips: UNH organic dairy takes gold for milk quality

    In the last year, the Organic Dairy Research Farm has increased organic milk production by nearly 127,000 pounds as a result of management practices implemented by the farm’s new manager Ryan Courtright. A dairy farmer originally from Pennsylvania, Courtright began managing the farm in April 2017. In addition to improving management practices, he also has reduced feed costs at the farm. He considers the research farm as an important role model for the organic dairy industry in regards to herd health and management, and best business practices that improve the bottom line for producers.

    Fosters: UNH Research: Beetles bear offspring based on food scarcity

    By understanding the behavior of burying beetles related to their reproduction and parental care, scientists can better understand the genetic and physiological mechanisms that modify parental care behaviors of insects in variable environments.

    Morning Ag Clips: Beetles limit offspring when food is scarce

    “As humans, we have a pocketbook with a certain amount of currency available to pay for food, housing, and clothing. This pocketbook is limited and informs what we can afford to purchase and support. The beetles are much like this. If resources are limited, then the number of offspring they can successfully raise also is constrained,” said NH Agricultural Experiment Station researcher Daniel Howard, assistant professor of biological sciences.

    Beetle Parents Choose to Limit Offspring When Food is Scarce

    Researchers have long known that many primates make decisions about the number of children they have based on the availability of resources such as food. Now new research from the New Hampshire Agricultural Experiment Station at the University of New Hampshire finds that some insects – specifically burying beetles – also choose to limit offspring when food is scarce.

    Farms.com: UNH Research Finds Feeding Pregnant Dairy Cows Niacin Improves Quality of Milk

    Feeding pregnant dairy cows the vitamin niacin prior to giving birth improved the quality of their colostrum, which is the first milk calves drink, according to new research from the University of New Hampshire. Colostrum is essential to building the immune systems of calves, and thus, their survival.

    Fosters: UNH finds a key to better milk quality

    “Calves are the foundation of the herd and are necessary to replace the cows that leave the herd for various reasons,” said Peter Erickson, professor of dairy management who conducted the research with Kayla Aragona, a doctoral candidate in animal science. “They also are the third greatest cost for the dairy producer, behind feed and labor, respectively. Reducing health costs and improving growth will result in a better bottom line for the producer.”
