In insects like grasshoppers, the Y chromosome is absent, so there are XO males and XX females. In birds and moths, females are heterogametic, with ZW and ZO chromosomes. Further, haplodiploidy operates in insects, such as ants and honey bees. Besides, temperature also impacts sex determ...
Are there more species of large or small animals? Which animals are likely to be monogamous? What is social monogamy and why might it be advantageous for some species? Consider an animal whereby a male has the option to stay and guard a female or wander to find multiple females. How can...
During single flower visits, males and workers caused similar levels of pollen deposition and seed production, yet female bees left fewer pollen grains in anthers to be transferred to other stigmas in the plant population. Overall, male bumble bees are common and capable pollinators of G. ...
First, there is the mother, or queen bee, (3) which lays the eggs, each in a little cell made of wax. Then there are the male bees. Next come the most numerous class of all, the workers. Some of these build a great many litle six-sided wax cells within the hive; while others...
To our knowledge, there are no studies investigating the role of parental practices in shaping adolescent atti- tudes toward sexting. However, previous studies focus- ing on parents' role in affecting adolescent sexual attitudes in 'traditional' settings (i.e., in the real world), have shown ...
Everyone knows that bees are busy. There is even a saying in English that one can be“as busy as a bee". However, little is known about how bees play. Scientists have discovered one way that bees could relax after a busy day making honey-they play with balls.The scientists are from ...
Unlike a honey bee colony, there are no workers, no honey production, nor any comb building. The eggs hatch and the young bees progress through the larval stage to the pre-pupal stage before winter sets in. During the winter they remain in the pre-pupal stage until early spring when ...

5 bees rolled (滚动) more balls than old bees. Adult male (雄的) bees 6 more time playing with the balls than female (雌的) bees did.There 7 45 bees in the tests. They had two choices. The first one was to fly or walk directly (直接地) to eat sweet food. The second one was...
There were some specialist bee species in our data that rarely visited their nominal pollen hosts, and five species that never visited them (Fig. 1). These bee species might be dominated by records of male bees, which do not provision nests with pollen, and likely make fewer trips to their...
