The LTAR Grazing Land Common Experiment at Northern Plains.

The USDA Long-Term Agroecosystem Research (LTAR) network aims to enhance sustainable agricultural management practices through a coordinated, cross-site common experiment involving 18 locations across the United States. The objective of this paper is to provide an overview of the LTAR Grazing Land Common Experiment at the Northern Plains (NP) site, where an experiment was initiated in 2019 to answer producers' and researchers' questions about whether the tactical application of fire or grazing can reduce the dominance of invasive Kentucky bluegrass in northern Great Plains ecosystems. As part of the LTAR common experiment, we contrast a prevailing practice (season-long grazing at moderate stocking rate) with four alternative practices at a half-hectare plot scale: (1) mob grazing by cattle, (2) multi-species grazing (mob grazing by cattle, with goats foraging at key times of the year), (3) prescribed fire, and (4) prescribed fire followed by cattle grazing.

On-farm harvest timing effects on alfalfa weevil across the Intermountain West region of the United States.

Alfalfa ( L.) is an economically important commodity in the Intermountain Western United States. A major concern for alfalfa producers in this region is the alfalfa weevil ( Gyllenhal).

Evaluating the use of common grasses by the wheat stem sawfly (Hymenoptera: Cephidae) and its native parasitoids in rangeland and Conservation Reserve Program grasslands.

The wheat stem sawfly, Cephus cinctus Norton (Hymenoptera: Cephidae), is a major pest of wheat (Triticum aestivum L., Poales: Poaceae) across the northern Great Plains of North America. Cephus cinctus has a wide host range, attacking numerous wild grasses and cultivated cereals in crop and grassland habitats, where it is, in turn, attacked by 2 native braconid parasitoids.

Isolation and Annotation of Azira, a CT Cluster Phage That Infects Gordonia rubripertincta.

Azira is a CT cluster actinobacteriophage that infects Gordonia rubripertincta NRRL B-16540. The genome contains 67 predicted protein coding genes, of which 31 have a putative function. Azira has a lysis cassette encoding two endolysins and three transmembrane proteins.
