Tooth microwear formation rate in Gasterosteus aculeatus
نویسندگان
چکیده
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 days, as in mammals.

1. The threespine stickleback Gasterosteus aculeatus is an important model organism in studies of genomic and phenotypic evolution, adaptation and speciation. Fossil Gasterosteus offer the potential to test models derived from studies of extant fishes over true evolutionary time-scales. Competition for food resources, for example, plays an important part in stickleback speciation, causing diver...

The egg nest of male three-spined sticklebacks Gasterosteus aculeatus is constructed with a gluelike secretion that this study demonstrates has antimicrobial properties. Glue collected from reproductively active males decreased the growth rate of bacteria and opportunistic fungi, and eggs were more likely to mature and hatch after exposure to their father’s glue. This phenomenon may represent a...
