Chemical triggering of reproduction in Microtus montanus.
نویسندگان
چکیده
In a replicated experiment, nonbreeding winter populations of Microtus montanus were given supplements of rolled oats coated with 6-methoxybenzoxazolinone, a naturally occurring plant derivative. After 3 weeks of this feeding regime, samples from the populations demonstrated a high incidence of pregnancy in females and testicular hypertrophy in males. Control populations receiving rolled oats coated only with the solvent showed no reproductive activity. These results demonstrate that the presence of 6-methoxybenzoxazolinone in the plant food resource acts as the ultimate cue to trigger reproductive effort in Microtus montanus.

The effect of mating upon LH release in male and female voles of the species Microtus agrestis.
Members of the microtine species are probably reflex ovulators. The prairie vole, Microtus ochrogaster (Richmond & Conway, 1969), the meadow vole, M. pennsylvanicus (Clulow & Mallory, 1970), the levant vole, M. guentheri (Bodenheimer & Sulman, 1946), the Californian vole, M. californicus (Greenwald, 1956), and the montane vole, Microtus montanus (Gray, Davis, Zerylnick & Dewsbury, 1974) have al...

Objective The success rates of assisted reproduction technology (ART) could be developed with the improvement of ovarian stimulation protocols as well as the optimization of final oocyte maturation. The goal of this study was to compare oocyte maturation, fertilization and pregnancy rates among women with concomitant FSH administration at the time of hCG trigger and the hCG trigger alone. Mater...
متن کاملDiscrimination Between Microtus Longicaudus and Microtus Montanus Using Cranial Morphology, External Measurements, DNA Sequencing, and Discriminate Function Analysis
Montane and Long-tailed voles (Microtus montanus and Microtus longicaudus) are notoriously difficult to distinguish through external characteristics and measurements in the field, particularly among juveniles. Being able to accurate identify these species is important, due to their central role in ecosystems (as keystone species) and as indicator species of climate change (due to their high sen...
