There is little advantage in adaptations that permit successful competition with other organisms, because the environment is likely to change again. Among the traits that are thought to characterize r-selection are high fecundity, small body size, early maturity onset, short generation time, and the ability to disperse offspring widely.
Suzanne Batra introduced the term "eusocial" [1] after studying nesting in Halictid bees including Halictus latisignatus, [2] pictured.. The term "eusocial" was introduced in 1966 by Suzanne Batra, who used it to describe nesting behavior in Halictid bees, on a scale of subsocial/solitary, colonial/communal, semisocial, and eusocial, where a colony is started by a single individual.
After approximately 7–10 days, the virgin queens take their mating flights, mate with 10–20 drone bees, and return to their mating nuclei as mated queen bees. [17] Queen rearing can be practiced on a small scale by hobbyist or sideline beekeepers raising a small number of queens for their own use, or can be practiced on a larger, commercial ...
In evolutionary biology, parental investment is the expenditure of time and effort towards rearing offspring that benefits the offspring's evolutionary fitness at a cost to parents' ability to invest in other components of the species' fitness. Parental care requires resources from one or both parents that increases the fitness of their ...
Sexual selection is an evolutionary concept that has been used to explain why, in some species, male and female individuals behave differently in selecting mates. In 1930, Ronald Fisher wrote The Genetical Theory of Natural Selection, [3] in which he introduced the modern concept of parental investment, introduced the sexy son hypothesis, and introduced Fisher's principle.
The psychology of the caretakers, particularly parental ethnotheories of child development and parenting, which play a directive role in actual practices. The three subsystems of the developmental niche - settings, customs, and caretaker psychology - share the common function of mediating the child's developmental experience within the larger ...
