As a result, high JH titers are positively associated with female fertility, and treatment with JH increases fertility in many taxa (Flatt and Kawecki, 2007; Tibbetts and Crocker, 2014; Tibbetts and Izzo, 2009). There is less consistent evidence that JH mediates male fertility or stimulates ...
The hallmark of eusociality is the reproductive division of labour, in which one female caste reproduces, while reproduction is constrained in the subordinate caste. In adult worker honeybees (Apis mellifera) reproductive constraint is conditional: in the absence of the queen and brood, adult worker...
Another kind of bee is the drone(雄蜂).Drones are male bees,and their job is to fly with the queen bee and mate with her.After the queen mates,the worker bees drive the drones away.The drones then starve to death. The third kind of bee is the queen.Each hive nee...
The effect of worker-produced males is to reduce Ne if the sex ratio is unity or female biased, however Ne is increased, compared to its value with t' = 0, if the sex ratio is male biased. The proportional changes in N for various values of cli and different sex ratios are given ...
Worker bees will attack anything—even people—to keep their hive safe. Another kind of bee is the drone(雄蜂). Drones are male bees and their job is to fly with the queen bee and mate with her. After the queen mates the worker bees drive the drones away. The drones then starve to...
We used similar models to examine size differences between male broods and between sexes. To examine variation among adult bees in dry weight, fat weight and relative fat content (fat weight divided by total dry weight), we included the type of female or the sex as a fixed effect in ...
Extreme altruism is found in colonies of eusocial Hymenoptera (ants, bees and wasps), where the workers forgo their own reproduction to help the queens produce offspring [2]. Such reproductive division of labor evolved in a context of high genetic relatedness, with a single female reproductive ...
