Population
The Varecia variegatta population is on a downward trend. The general population is decreasing dramatically. Studies have shown overtime that in the last 27 years there has been an 80% decrease in individual black and white ruffed lemurs. From the Vasey studies of 2003 it was shown that the most densely populated area of black and white ruffed lemurs was Nosy Mangabe. It had around 29-43 individuals/km2. Consequently came Anatanamatazo with 10-15 individuals/km2, and then Manomba with.4-2.5 individuals/km2.

Famous quotes containing the word population:
“[Madness] is the jail we could all end up in. And we know it. And watch our step. For a lifetime. We behave. A fantastic and entire system of social control, by the threat of example as effective over the general population as detention centers in dictatorships, the image of the madhouse floats through every mind for the course of its lifetime.”
—Kate Millett (b. 1934)
“Like other cities created overnight in the Outlet, Woodward acquired between noon and sunset of September 16, 1893, a population of five thousand; and that night a voluntary committee on law and order sent around the warning, “if you must shoot, shoot straight up!””
—State of Oklahoma, U.S. public relief program (1935-1943)
“What happened at Hiroshima was not only that a scientific breakthrough ... had occurred and that a great part of the population of a city had been burned to death, but that the problem of the relation of the triumphs of modern science to the human purposes of man had been explicitly defined.”
—Archibald MacLeish (1892–1982)
