Bioextractive removal of nitrogen by oysters in Great Bay-Piscataqua river estuary, New Hampshire, USA New research on the Eastern oyster (Crassostrea virginica) show that both farmed and wild oyster filter nitrogen from the water, processing the element in their shells and soft tissues and helping reducing cases of eutrophication. In a recent paper, scientists showed that oysters and other shellfish can help complement land-based nutrient management practices, such as upgrades to wastewater treatment plants around New Hampshire’s Great Bay estuary to reduce nitrogen output.

Breeding edible and ornamental strawberries for New England With over 700,000 pounds produced and $2.3 million in farm sales, strawberries are an important crop for New Hampshire farmers. But improving the cultivated strawberry through breeding is particularly challenging. The cultivated strawberries has four times as many chromosome sets as humans, animals and most other crops, which significantly increases its genomic complexity. Research to untangle the plant's genetic structure will enable scientists to more quickly and effectively develop cultivated strawberry varieties that help New England farmers be more resilient and successful.

Can at-risk species serve as effective conservation surrogates? Case study in northeastern US shrublands An unintended impact of land-use changes over the past century has been a more than 86 percent decrease in the range of the New England cottontail. Ongoing habitat restoration efforts will help the survival of the New England cottontail, and new research by COLSA researchers finds that these efforts will also benefit at least 12 shrubland-obligate bird species with which the cottontail shares its habitat.

Crop rotational complexity affects plant-soil nitrogen cycling during water deficit When it comes to crop rotations, complexity is key to boosting levels of nitrogen—a soil nutrient that is critical to crop production. That's according to new research involving NHAES Station scientist and professor of natural resources and the environment Stuart Grandy.

Disease threats and biofungicide efficacy in soilless substrates In greenhouse production, plants are not typically grown in soil but in soilless growth substrates. For decades, peat moss has been the primary substrate for container-grown ornamentals and for some vegetable crops. However, substrate suppliers have faced unprecedented demand, which has led to product shortages and an inability to fulfill orders. Substrate manufacturers have identified wood byproducts to be some of the most promising alternative sources of raw materials to use in substrate formulations. This research considers how wood substrate components affect the severity of soil-borne diseases in greenhouse horticultural crop production.

Dominance of diffusive methane emissions from lowland headwater streams promotes oxidation and isotopic enrichment Different aquatic bodies play different roles in the release of methane gas. Wetlands, lakes, and reservoirs all play large roles in releasing methane directly into the atmosphere. Rivers and streams weren’t historically viewed as important pieces of the global methane cycle. However, recent research from COLSA and NHAES shows that streams are dynamic places of methane production and oxidation.

Effect of selisseo on selenium in milk and in blood for mid- and late-lactation holstein cows Selenium (Se) is an essential trace mineral that, if deficient in soil, will be deficient in diets fed to dairy cows. Adequate Se is important for animal health to support immune functions and efficiently fight oxidative stress and pathogens. Standard farm practice is to supplement Se in the diet either in mineral form (sodium selenite) or organic forms. This study compared the bio-efficacy of two organic Se sources in mid-lactating dairy cows based on the Se transfer into plasma and milk.

Effect of sodium butyrate, monensin, and butyric acid on Eimeria bovis sporozoites COLSA scientists Pete Erickson and Tom Foxall led research that found evidence that the compound sodium butyrate—a nutrient that people obtain by consuming beans, peas and other legumes, but that can also be added to animal feed—could be used as a coccidiosis preventative in cattle. Coccidiosis is an intestinal disease that affects livestock around the world.

Effects of incremental amounts of red seaweed on milk production, composition and methane emissions Enteric fermentation (fermentation taking place in the digestive system of animals) by ruminants is the largest source of methane emissions in the US (approximately 25% of total methane emissions). Recently, algae-based feeds have gained attention because they may be able to not only suppress methane emissions, but also to improve animal feed efficiency. Our objective was to evaluate how incremental increases of the seaweed Chondrus crispus affects milk and methane production in organic dairy cows.

Enhancing the characterization of forest community composition, structure, and health using unpiloted aerial systems New Hampshire has 80 percent forest cover and assessing the health and composition of this significant forestland is crucial for management and economy. This research by New Hampshire Agricultural Experiment Station scientists explores the possibility of using unpiloted aerial systems to overcome the limitations of traditional forest assessments and provide more informative characterizations of northeastern forests.

Examining beech bark disease: Fungal pathogens and bark responses Beech bark disease (BBD) spreads via invasive scale insects & fungal pathogens, killing beech trees. Despite research, the role of the two fungal pathogens in BBD progression and the impact of insect attack on beech bark is not fully understood. This research—conducted by scientists from the New Hampshire Agricultural Experiment Station at the University of New Hampshire—examined the distribution of BBD fungal pathogens and beech bark's response to insect and pathogen attack.

Extreme rainstorms drive exceptional organic carbon export from forested humid-tropical rivers in Puerto Rico Tropical rivers that flow directly to oceans play an important role in capturing, storing, and preventing organic carbon from converting to carbon dioxide, according to research co-authored by Bill McDowell, professor of Natural Resources and the Environment at COLSA.
