For the metapopulation of Daphnia in Scandinavian freshwater pools, which situation would be most likely to result in maintenance of the metapopulation, rather than its extinction? A) Immigrants increase the genetic diversity of pools, slightly increasing r. B) Years of drought decrease the average size of all pools. C) Small pools “wink off” and are not repopulated by dispersal from larger pools. D) The pools are mostly small, and there is no dispersal among them. E) Dispersal among pools is infrequent, and many pools reach zero density.

Conservation Biology

The study of how to prevent the loss of biological diversity on the planet is called conservation. Biological diversity, also termed biodiversity, consists of various life forms found in a specific location or across the entire planet, including ecosystems, species, populations, and genes. Conservation thus aims to protect the diversity of life at all levels of biological organization.
