Grasses are flowering plants in the family Poaceae (the grass family), which includes an estimated 12,000 species. Grasses are one of the most dominant types of plants on Earth today, estimated to make up about 20% of global vegetation. They include economically important cereal crops (for example, wheat, oats, rye, corn, barley, rice, and millet), as well as turf, landscaping, and forage plants. They are significant sources of sugar, fuel, and other products. Grasses have been important throughout human history, from the earliest domestication of plants to the global food system today.
The purpose of the new Grasses section of [email protected]: Evolution is to provide an overview of grasses, including their biology, diversity, genetics, domestication, and significance to human society, with a special emphasis on grasses in Tribe Andropongoneae, commonly known as the Bluestem Tribe or the Sorghum Tribe.
Climate Change Adaptation
November 18, 2022
While it is imperative that we continue to expand our mitigation efforts to limit the amount of human-caused climate change, we also need to find ways to adapt to changes that are already happening. Adaptation will help us become more resilient to extreme weather and other climate hazards that we'll face in the future even as we work to reduce our emissions of greenhouse gases.
This new chapter of the Digital Encyclopedia of Earth Science explores existing and proposed adaptation strategies for a variety of climate hazards and examines some of the challenges these strategies present.
Earth Science of the NorthwestCentral United States
November 2, 2022
Explore the Earth science of the Northwest-Central United States, including its geologic history, rocks, fossils, topography energy, mineral resources, climate, glaciers, and Earth hazards.
Here on Earth: Regional Guides to Earth Science
The goal of this part of the [email protected] project is to explain the Earth science of every region of the United States and provide necessary background information. Each region is divided into physiographic provinces: regions that are naturally defined by their modern topography and geologic history. The map below shows the major physiographic regions of the contiguous United States that we are recognizing in [email protected]
Regions of Here on Earth that are now finished include:
Regions of Here on Earth that are currently in development include:
- Midwestern United States
- Northeastern United States
Digital Encyclopedia of Earth Science
Free, open-access Earth science textbook. Over the next several years, the Digital Encyclopedia of Earth Science will grow to cover most Earth science topics. Initial subjects covered include big ideas, minerals, fossils, climate, and climate change (links below). "Quick Introductions" provide brief overviews of that will be expanded upon in later Digital Encyclopedia chapters.
Newest chapter: Climate Change Mitigation by Dr. Ingrid Zabel.
