grassland : an ecological community in which the characteristic plants are grasses — Webster
Grasslands are areas where the vegetation is dominated by grasses (Poaceae); however, sedge (Cyperaceae) and rush (Juncaceae) families can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur naturally on all continents except Antarctica. Grasslands are found in most ecoregions of the Earth. For example, there are five terrestrial ecoregion classifications (subdivisions) of the temperate grasslands, savannas, and shrublands biome (ecosystem), which is one of eight terrestrial ecozones of the Earth’s surface. — Wikipedia

- How do aggregates of different sizes mediate...on January 22, 2021 at 1:20 pm
Aggregates of different sizes provide heterogeneous microhabitats for soil microorganisms, which in turn drive the cycling and transformation of soil materials and energy, and have different effects on key processes related to nutrient supply and storage. The role of soil aggregates in ecosystem services such as carbon sequestration, fertilizer preservation and erosion prevention has been widely studied. However, little is known about their roles in mediating the relationship between soil and […]

The White-lipped peccary (Tayassu pecari) is a boar-like hoofed mammal found throughout Central and South America. These animals roam the forest in bands of 50 to 100 individuals, eating a wide variety of foods. In Brazil's Atlantic Rainforest, they prefer the fruit of the jussara palm Euterpe edulis.

Each year, thousands of migratory mule deer and pronghorn antelope journey northwest from their winter homes in the Green River Basin, a grassland valley in western Wyoming, to their summer homes in the mountainous landscape near Grand Teton National Park.

A year after a global coalition of more than 11,000 scientists declared a climate emergency, Oregon State University researchers who initiated the declaration released an update today that points to a handful of hopeful signs, but shares continued alarm regarding an overall lack of progress in addressing climate risks.
- Uncovering how grasslands changed our climateon January 5, 2021 at 12:31 pm
Grasslands are managed worldwide to support livestock production, while remaining natural or semi-natural ones provide critical services that contribute to the wellbeing of both people and the planet. Human activities are, however, causing grasslands to become a source of greenhouse gas emissions rather than a carbon sink. A new study published in Nature Communications reports how grasslands used by humans have changed our climate in recent centuries.
