TL;DR: The impact of Bt corn pollen from current commercial hybrids on monarch butterfly populations is negligible, according to a 2-year study by scientists in several states and in Canada.

TL;DR: There has been a large decline in milkweed in agricultural fields in the Midwest over the last decade, coincident with the increased use of glyphosate herbicide in conjunction with increased planting of genetically modified (GM) glyphosate‐tolerant corn (maize) and soybeans (soya).

TL;DR: This article studied the outcome of a professional development opportunity that consisted of 2-week-long resident institutes for teams consisting of a secondary science teacher and two students, and found that the characteristics of the program that helped teachers successfully translate inquiry to their classrooms were: deep science content and process knowledge with numerous opportunities for practice; the requirement that teachers demonstrate competence in a tangible and assessable way; and providers with high expectations for learning and the capability to facilitate multifaceted inquiry experiences.

TL;DR: In this article, a framework for assessing the impacts of bio-fuels on wildlife is presented, and the authors use this framework to evaluate the impact of existing and emerging bio-fuel feedstocks on grassland wildlife.

TL;DR: It is found that monarchs use milkweed in cornfields throughout their breeding season, and that per plant densities are as high or higher in agricultural habitats as in nonagricultural habitats, suggesting that agricultural practices such as weed control and foliar insecticide use could have large impacts on monarch populations.
