The effective size of a natural drosophila subobscura population

Heredity (Edinb). 1977 Feb;38(1):13-8. doi: 10.1038/hdy.1977.2.

Abstract

The effective size of a natural Drosophila subobscura population has been computed by drawing together various pieces of ecological information. The value, for both variance and inbreeding effective numbers, is approximately 400. This is largely due to reductions caused by a winter bottleneck and non-random distributions of family sizes. Areas where such estimates might be refined further are pointed out, and the implications of the results are discussed.
