Isofemale Strains and Evolutionary Strategies in Natural Populations,cently, electrophoretic studies stressing discontinuities. Even alleles that are effectively discrete at the molecular level contribute to quantitative variation at “higher” phenotypic levels. Because there has been strong emphasis upon the study of one or a few loci where allelic substitutions have

Reproductive Behavior and Mating Success of Male Short-Tailed Crickets: Differences within and betwand some grasshoppers are the birds and frogs of the insect world. Males loudly advertise their species, sexual readiness, and location. Biologists can use these acoustical displays to detect sibling species, to find local populations and individuals for study, and to determine seasonal, ecological,

One of the clearest predictions in this literature relates the spatial relationships of individuals to the distribution of food in their environment. Specifically, when food is sparse, evenly distributed, and slowly renewing, and when individuals have fixed bases of operation, like nests or c

Estimation of Disequilibrium Modelsdependent selection could be true not only when considering different species, but even when one considers the genetic variance as this may be expressed over different loci within the same local population of one species, and the two modes of selection may vary in importance from one local population to another.

According to theories of regulation of recombination systems, a wide array of structural and ecological features of organisms, including sexuality vs. asexuality, are adjusted together to produce a supposedly optimal supply of genetic recombinants (Darlington, 1939; Grant, 1975).

This prediction is supported in a general way by comparative reviews of a number of taxonomic groups of birds and mammals (Crook, 1965; Lack, 1968; Brown and Orians, 1970; Waser and Wiley, 1979).
