XXI.—Observations on the nidification of Gasterosteus aculeatus and Gasterosteus spinachia

Tooth microwear formation rate in Gasterosteus aculeatus

Tooth microwear feature densities were significantly increased in a population of laboratory-reared three-spined stickleback Gasterosteus aculeatus in four days, after they were transferred from a limnetic feeding regime to a benthic feeding regime. These results show that even in aquatic vertebrates with non-occluding teeth, changes in feeding can cause changes in tooth microwear in just a few...

Sequencing the genome of threespine sticklebacks (Gasterosteus aculeatus)

The oxygen consumption of Gasterosteus aculeatus L. in toxic solutions.

INTRODUCTION The respiratory exchange of entire organisms, isolated organs and tissues is a widely explored field in physiology, dating back to the classic work of Lavoisier, and in recent times still presents fresh problems for study, as, for instance, the work of Davis & Fraenkel (1940) on the oxygen consumption of flies during flight. Literature prior to 1916 is reviewed and catalogued in th...

Temporal 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...

Evidence of trophic transfer of microcystins from the gastropod Lymnaea stagnalis to the fish Gasterosteus aculeatus.

According to our previous results the gastropod Lymnaea stagnalis exposed to MC-producing cyanobacteria accumulates microcystins (MCs) both as free and covalently bound forms in its tissues, therefore representing a potential risk of MC transfer through the food web. This study demonstrates in a laboratory experiment the transfer of free and bound MCs from L. stagnalis intoxicated by MC-produci...
