This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Human activity is driving an increase in the amount of atmospheric reactive nitrogen. California grassland growth is typically limited by the amount of available nitrogen. Thus, more available nitrogen leads to more plant biomass, which means more carbon is deposited in the soil. Both the increase in nitrogen itself and the increase in carbon affect soil microbes. To better understand these impacts, a recent study examined microbial metabolic functioning in experimental grassland plots in California. These plots had been maintained for 14 years with increased nitrogen deposition mimicking the predicted levels for the end of the 21st century. This increased deposition led to an increased abundance of fast-growing bacterial species, as well as an increased capacity to use easily accessible, or labile, carbon sources. In contrast, the community's capacity to degrade recalcitrant carbon sources was unchanged or even decreased by elevated nitrogen..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.

Learn how important the honey bee's body structure is to survival in the hive.What if there were no bees? How would it affect our grassland animals? How would it affect humans? This learning module offers insight into the problems that countless animals and plants face with the potential loss of the bees. Discover just how important this tiny species is to the food web of this ecosystem.This module could be incorporated into a larger environmental science module.This lesson includes learning objectives, material and resource lists, background information, activities,  videos, writing assignments, a game, assessments, and support documents. See the Educator's Guide for more video links and recommended readings. Remix of: 1.Create a Bee Hummer, Science Snacks Exploratorium 2. What If There Were No Bees? A Bee Cause Project 3. Hive Alive!

This lesson provides teachers with support for using text-dependent questions and Common Core literacy strategies to help students derive big ideas and key understandings while developing vocabulary using the nonfiction informational text, Wildfires. Wildfires can cause damage but also play a critical role in the renewal of forests and grasslands. Through the example of the 1988 Yellowstone fire, Wildfires highlights the effects and cycles of fires and shows the reader how critical fire is to regenerating forests and grasslands.
