Comparing the impacts of patch‐burn grazing on vegetation in two northern tallgrass prairies

Conservation Science and Practice, Volume 7, Issue 10, October 2025.
We evaluated two of the earliest and largest patch‐burn grazing projects in the eastern tallgrass prairie of Minnesota, an ecosystem that has undergone extensive fragmentation and invasion by non‐native species. Our results in grazed and ungrazed plots varied with differences in stocking rate and fire frequency.

Genetic diversity and population structure of ALS‐resistant Amaranthus hybridus across Brazil's primary soybean‐growing regions

Pest Management Science, Volume 81, Issue 9, Page 5394-5402, September 2025.
We identified two distinct target‐site mutations, Asp‐376‐Glu and Trp‐574‐Leu, that confer resistance to acetolactate synthase inhibitors in Amaranthus hybridus populations across Brazil's soybean‐growing regions. These findings suggest multiple independent origins of resistance, with its spread primarily driven by local herbicide selection pressure ...

GM Crops and the Jevons Paradox: Induced Innovation, Systemic Effects and Net Pesticide Increases From Pesticide‐Decreasing Crops

Journal of Agrarian Change, Volume 25, Issue 3, July 2025.
ABSTRACT The Jevons paradox describes how increased efficiency in the use of a resource can paradoxically increase rather than reduce its overall consumption. In agricultural systems, efficiency is confounded by a broad range of economic, ecological, social and evolutionary factors. Agriculture is a particularly elastic kind of production: Efficiencies
