A critical success factor for information systems is their ability to evolve as their environment changes. There is compelling evidence that the management of change in business policy can have a profound effect on an information system’s ability to evolve effectively and efficiently.

Journal of Experimental Biology, 2003 ![Figure][1] Social insects such as honey bees live in complex societies, and it is a fascination to many scientists how bees co-ordinate their behaviour according to the needs of the colony.

Genetic relationships between brooding and brooded Actinia tenebrosa
Nature, 1975SEA anemones of the genus Actinia seem to be dioecious and reproduce sexually, yet males, females, and individuals without gonads brood juveniles for much of the year1–3. How this occurs is still not understood and knowledge on the subject is scant. Gillespie4 considered that eggs develop to ciliated blastulae and then directly into “a cylindrical form

Brood reduction and brood division in coots
Animal Behaviour, 1984Abstract The probability of starvation of chicks increases through hatching order in broods of the coot, Fulica atra . After hatching chicks accompany, and are fed by, parents as they swim around the territory. The time that chicks are able to spend outside the nest increases rapidly with age, so that the earlier hatching chicks gain a feeding ...

Parental care promotes the survival and well-being of the offspring, and species, at a cost of resources to the parents as well as the apparently sacrificial acts of individual parents. This important vertebrate behavior is the most obvious and pervasive example of altruism in the kingdom Animalia representing the original form of prosocial behavior ...

The Significance of Brood [PDF]
, 2014 Differences in colony size among Apis species are not equated to the ratio of drones to workers or associated comb construction. Oviposition-related cell inspections reveal that a queen’s decision to lay a fertilized egg or not, is determined by a specific stimulus generated on cell inspection.

Brooding and the evolution of hermaphroditism
Journal of Theoretical Biology, 1979Abstract It has been suggested that hermaphroditism may evolve when the resources that females can profitably allocate to ova is limited by factors such as lack of brooding space. Spare resources could then be allocated to produce male gametes in a hermaphrodite.
