The similarity of changes in community structure both across replicates and genotypes over the course of the passaging experiment led us to predict that these microbiomes were adapting to the local plant and greenhouse environment. To further determine if the community changes we observed from P1 to P4 were due to habitat selection rather than […]

The human immune system maintains a homeostatic relationship with commensals through numerous mechanisms, including stratification and compartmentalization of the intestine, production of a mucous layer and antimicrobial proteins, and limiting epithelial exposure and immune response. Two studies in Arabidopsis thaliana demonstrate that disrupting components of the plant immune system, such as the signaling molecules salicylic […]

Similarly, according to Tena’s chronography, the summer solstice took place toward the end of the sixth month, called Etzalqualiztli. At that time, sunrise would have seemed to stand still at an azimuth of ca. 65°. Viewed from the top of the Templo Mayor, sunrise would have taken place behind Tepetlaoxtoc, in the western foothills of […]

By crops, we mean either annual or perennial crops, including tree crops. At the field scale, DFS may include polycultures, noncrop plantings such as insectary strips, integration of livestock or fish with crops , and/or rotation of crops or livestock over time, including cover cropping and rotational grazing. Around the field, DFS may incorporate noncrop […]

This research would be incomplete without a description of the presence of spousalrun dairy farms in the U.S. A spousal-run dairy refers to a dairy that is managed by two operators that are married to one another. There is a historic assumption that many dairy farms are run by spouses, however, this research finds that […]

Although dairy farm size can be characterized for the U.S. overall, there are important distinctions by state, as the dairy farm size distributions differ greatly by state. It is important to distinguish growth patterns of dairy farms by state. Macdonald et al. detail that larger dairy farms are able to capture economies of scale, more so […]

The wind turbine stands on a tubular steel tower, with a base diameter of 1.9 m. The drive train generator operates at 1200 rpm, while the rotor spins at a nominal speed of 55 rpm. The Micon 65/13M wind turbine was used for the Long-Term Inflow and Structural Testing program at the USDA-ARS test facility in […]

As there were multiple observations per individual , a random intercept was used for individuals. Utilization of places for each person was estimated using two different approaches. The first method was by checking whether more than two temporally-consecutive GPS points of a person fall within a polygon designated for the person’s home , farms, or forests […]

Our group has demonstrated the applicability of this process by generating hydrolysates with high concentrations of monomeric sugars and organic acids from several feed stocks like grasses, hardwoods, and softwoods, and converting them to terpene-based jet-fuel molecules using engineered strains of the yeast Rhodosporidium toruloides . Nevertheless, it is important to expand the range of lignocellulosic […]

Study of cannabis as an agricultural crop has been notoriously inadequate, but data provided by the water quality control board’s cannabis program offers critical new insights into the water use practices of cultivators entering the regulated industry. In this initial analysis, we found that subsurface water may be much more commonly used in cannabis cultivation […]
