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

DNA traces on wild flowers reveal insect visitors
on February 8, 2019 at 1:42 pm
Researchers from Aarhus University, Denmark, have discovered that insects leave tiny DNA traces on the flowers they visit. This newly developed eDNA method holds a vast potential for documenting unknown insect-plant interactions, keeping track of endangered pollinators, such as wild bees and butterflies, as well as in the management of unwanted pest species.
