Genetic divergence of a sympatric lake-resident-anadromous three-spined stickleback Gasterosteus aculeatus species pair.
The genetic relationship between sympatric, morphologically divergent populations of anadromous and lake-resident three-spined stickleback Gasterosteus aculeatus in the Jim Creek drainage of Cook Inlet, Alaska, was examined using microsatellite loci and mitochondrial d-loop sequence data. Resident samples differed substantially from sympatric anadromous samples in the Jim Creek drainage with th...
متن کاملTemporal Stability of Genetic Variability and Differentiation in the Three-Spined Stickleback (Gasterosteus aculeatus)
Temporal variation in allele frequencies, whether caused by deterministic or stochastic forces, can inform us about interesting demographic and evolutionary phenomena occurring in wild populations. In spite of the continued surge of interest in the genetics of three-spined stickleback (Gasterosteus aculeatus) populations, little attention has been paid towards the temporal stability of allele f...
متن کاملInterspawning interval of wild female three-spined stickleback Gasterosteus aculeatus in Alaska.
The interspawning interval, or spawning frequency, of wild three-spined stickleback, Gasterosteus aculeatus, was estimated using histological examination of postovulatory follicles (POF). Females in Alaskan lakes appeared to have as much as a 48 h delay between ovulation and ovoposition, yet the POF method could still be used to estimate the interspawning interval. In two Alaskan lakes the inte...
متن کاملNon-invasive measurement of 11-ketotestosterone, cortisol and androstenedione in male three-spined stickleback (Gasterosteus aculeatus).
The androgen 11-ketotestosterone (11-KT) plays an important role in reproductive physiology and behaviour in male teleosts. In the three-spined stickleback, Gasterosteus aculeatus, the plasma concentrations of 11-KT are related to the breeding status of the fish. Sticklebacks are relatively small (generally less than 1g) and in order to obtain sufficient plasma for assay of 11-KT, it has been n...
متن کاملLatitudinal variation in photoperiodic response of the three-spined stickleback Gasterosteus aculeatus in western North America.
Reproductive maturation in both male and female three-spined stickleback Gasterosteus aculeatus was strongly photoperiodic in a northern population (Alaska, 61 degrees N) but not in a southern population (Oregon, 43 degrees N) from western North America. Increasing reliance on photoperiod with increasing latitude is a general phenomenon among vertebrates, and is probably due to the anticipation...
