Calculate the area of a room or space by multiplying the length in feet by the width in feet. If the answer is 200, for example, then the space is 200 square feet. For 12-inch tiles, the total area is also the number of floor tiles required to cover the space. To calculate the appropriate number for other sizes of floor tiles, determine the size of that tile in square feet. For example, four 6-inch tiles make up one 12-inch tile.
A lekking species is defined by the following characteristics: male displays, strong female mate choice, and the conferring of male indirect benefits. Although lekking is most prevalent among avian species, lekking behavior is found in insects, amphibians, and mammals as well.
Eventually a female accepts the advances of a particular male and mates with it. Usually only a few males out of all those present on the lek ever successfully mate. The female then lays its eggs in a nest that may be distant from the lek and that will never be visited by the chosen male. Left: Lekking species, like the Sage Grouse shown here, reserve mating activity to traditional lekking grounds.
