Small Population Size, Kartoniert / Broschiert

Klappentext

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Small populations behave differently from larger populations. Often this has various harmful consequences for the survival of that population. The influence of stochastic variation in demographic rates is much higher for small populations than large ones. Stochastic variation in demographic rates causes small populations to fluctuate randomly in size. The smaller the population the greater the probability that fluctuations will lead to extinction. They are subject to a higher chance of extinction because they are more vulnerable to genetic drift, resulting in stochastic variation in their gene pool, their demography and their environment.
