Tooth microwear formation rate in Gasterosteus aculeatus

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...

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...

Oxygen consumption rate in Gasterosteus aculeatus-Schistocephalus solidus system from a non-migratory naturally infected population

The three spine stickleback Gasterosteus aculeatus is a specific obligatory intermediate host for the cestode worm Schistocephalus solidus. This system is commonly used to investigate the host-parasite interaction in fishes. Despite the interesting attempts which have been made to quantify the impact of the parasite over the respiration rate of the host fish, none of the previous reports took i...

Sequencing the genome of threespine sticklebacks (Gasterosteus aculeatus)

New model to explain tooth wear with implications for microwear formation and diet reconstruction.

Paleoanthropologists and vertebrate paleontologists have for decades debated the etiology of tooth wear and its implications for understanding the diets of human ancestors and other extinct mammals. The debate has recently taken a twist, calling into question the efficacy of dental microwear to reveal diet. Some argue that endogenous abrasives in plants (opal phytoliths) are too soft to abrade ...
