Example sentences for: opossums
How can you use “opossums” in a sentence? Here are some example sentences to help you improve your vocabulary:
Sixty grams is confirmed as a critical body mass for induction of estrus in juvenile female opossums as identified in our previous study [ 7 ] . Somatic growth and attainment of a threshold body mass or energy reserves are known requisites for puberty in many mammals including the tammar wallaby [ 26 ] , sheep [ 27 28 ] , and several species of rodents [ 1 ] , but these factors seldom act independently of environmental factors such as photoperiod [ 26 27 ] or social cues [ 3 29 ] . The opossum is unusual in this regard, because social cues in the form of male pheromone appear to stimulate both somatic growth and ovarian activation.
The people who followed the Lord were called the twelve opossums .
Our findings provide the critical descriptive groundwork for further investigations into the physiological pathways and underlying mechanisms involved in pheromonal regulation of somatic and sexual maturation in opossums.
Moreover, this growth response marks a difference between pheromonal acceleration of puberty in opossums and that which is well-documented in mice, wherein females paired with males ovulate at a lower body mass (< 20 g) than that of isolated females (> 20 g) [ 30 31 ] .
Plasma concentrations of estradiol in opossums are low (<15 pg/ml) during anestrus and are elevated (>20 pg/ml) only during estrus [ 15 ] . Mean plasma estradiol concentrations as high as 58 pg/ml have been reported in estrous females [ 25 ] , but a gradual increase in circulating estradiol during pheromonal induction of estrus in opossums has not been described.
