“…The studies on microgeographic variation in allozyme frequencies are not numerous, but they suggest that microspatial differentiation is a rule rather than an exception (e.g. Selander & Kaufman, 1975;Taylor & Powell, 1977;Richmond, 1978). The situation found here in Gerris resembles that in house mice, in which the mosaic allele frequency distribution within a small area looks like a variation pattern in large geographic areas (Selander, 1970).…”

Spatial and temporal differentiation in Gerris lacustris and G. odontogaster (Heteroptera, Gerridae) were studied in restricted areas, where one population of each species was subdivided into several subpopulations. The aim of the study was to relate genetic population parameters to ecological population structure studied by mark-recapture methods in the same pond systems. Marked differentiation between the subpopulations and significant enzyme allele frequency changes between subsequent generations were found at several loci. It is suggested that non-selective forces are a sufficient explanation for the observed differences.

“…However, conclusions based on electrophoretic and morphometric data often do not correspond (Schnell et al, 1978;Schnell and Selander, 1981) and decisions regarding the systematic status of this species should await further investigation (see Chesser, 1983). Thus, heterogeneity among wards is slightly greater than that among house mice from different barns or farms (F S T = 0.025 and 0.047 ;Selander and Kaufman, 1975) and for Indians from different villages (F S T = 0.040; Nei, 1975), is almost identical to that for different gopher populations (F S T = 0.049 and 0.066; Patton and Feder, 1981), but is slightly lower than that for marmots from different colonies (F S T = 0.07; Schwartz and Armitage, 1980). The average genetic differentiation among wards within a population was about 5% (F S T = 0.045 to 0.065; Table 3).…”

“…One such model proposed that the high level of genetic variation in wild barley is an adaptive strategy in response to a remarkably heterogeneous environment. Sharp geographical differentiation over very short distances appears to be common in plants (Allard and Kahler, 1971) as well as in landsnails (Selander and Kaufman, 1975). H. spontaneum is considered a habitat generalist and has correspondingly a high level of polymorphism.…”
