Phylogeography and Conservation Genetics of the Ibero-Balearic Three-Spined Stickleback (Gasterosteus aculeatus)
Genetic isolation and drift may imperil peripheral populations of wide-ranging species more than central ones. Therefore, information about species genetic variability and population structure is invaluable for conservation managers. The Iberian populations of three-spined stickleback lie at the southwestern periphery of the European distribution of Gasterosteus aculeatus. This teleost is a pro...
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 کاملMitochondrial DNA phylogeography of the three-spined stickleback (Gasterosteus aculeatus) in Europe-evidence for multiple glacial refugia.
An analysis of mitochondrial DNA sequence variation in 172 three-spined sticklebacks (Gasterosteus aculeatus) sampled across the European distribution range revealed three major evolutionary lineages occupying relatively large and separate geographic areas. The trans-Atlantic lineage comprised of populations spanning from the East Coast of USA to the continental Europe and was basal group to th...
متن کاملParental fanning behavior and prolactin cell activity in the male three-spined stickleback Gasterosteus aculeatus L.
During the period that sexually mature male three-spined sticklebacks display parental fanning behavior, the rate of synthesis and release of the prolactin cells in the hypophysis, as estimated with quantitative electron microscopy, is enhanced considerably. This finding points to involvement of endogenous prolactin in the regulation of parental fanning behavior in this species.
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...
