Self-reconfiguring modular robotModular self-reconfiguring robotic systems or self-reconfigurable modular robots are autonomous kinematic machines with variable morphology. Beyond conventional actuation, sensing and control typically found in fixed-morphology robots, self-reconfiguring robots are also able to deliberately change their own shape by rearranging the connectivity of their parts, in order to adapt to new circumstances, perform new tasks, or recover from damage.
Apis ceranaApis cerana, the eastern honey bee, Asiatic honey bee or Asian honey bee, is a species of honey bee native to South, Southeast and East Asia. This species is the sister species of Apis koschevnikovi and both are in the same subgenus as the western (European) honey bee, Apis mellifera. A. cerana is known to live sympatrically along with Apis koschevnikovi within the same geographic location. Apis cerana colonies are known for building nests consisting of multiple combs in cavities containing a small entrance, presumably for defense against invasion by individuals of another nest.
Pollinator declinePollinator decline is the reduction in abundance of insect and other animal pollinators in many ecosystems worldwide that began being recorded at the end of the 20th century. Multiple lines of evidence exist for the reduction of wild pollinator populations at the regional level, especially within Europe and North America. Similar findings from studies in South America, China and Japan make it reasonable to suggest that declines are occurring around the globe.
Economic entomologyEconomic entomology is a field of entomology, which involves the study of insects that benefit or harm humans, domestic animals, and crops. Insects that pose disadvantages are considered pests. Some species can cause indirect damage by spreading diseases, and these are termed as disease vectors. Those that are beneficial include those that are reared for food such as honey, substances such as lac or pigments, and for their role in pollinating crops and controlling pests. In the 18th century many works were published on agriculture.

List of honey bee pheromonesThe pheromones of the honey bee are mixtures of chemical substances released by individual bees into the hive or environment that cause changes in the physiology and behaviour of other bees. Honey bees (Apis mellifera) have one of the most complex pheromonal communication systems found in nature, possessing 15 known glands that produce an array of compounds. These chemical messengers secreted by a queen, drone, worker bee or laying worker bee to elicit a response in other bees.
Colonial history of the United StatesThe colonial history of the United States covers the history of European colonization of North America from the early 17th century until the incorporation of the Thirteen Colonies into the United States after the Revolutionary War. In the late 16th century, England (British Empire), Kingdom of France, Spanish Empire, and the Dutch Republic launched major colonization expeditions in North America. The death rate was very high among early immigrants, and some early attempts disappeared altogether, such as the English Lost Colony of Roanoke.
ColonyA colony is a territory subject to a form of foreign rule. Though dominated by the foreign colonizers, the rule remains separate to the original country of the colonizers, the metropolitan state (or "mother country"), within the shared imperialist administration. This colonial administrative separation, though often blurred, makes colonies neither annexed or incorporated territories nor client states. Colonies contemporarily are identified and organized as not sufficiently self-governed dependent territories.
Colony (biology)In biology, a colony is composed of two or more conspecific individuals living in close association with, or connected to, one another. This association is usually for mutual benefit such as stronger defense or the ability to attack bigger prey. Colonies can form in various shapes and ways depending on the organism involved. For instance, the bacterial colony is a cluster of identical cells (clones). These colonies often form and grow on the surface of (or within) a solid medium, usually derived from a single parent cell.
DomesticationDomestication is a multi-generational relationship between humans and other organisms, where humans take control over their reproduction and care to have a steady supply of the organisms' resources. It can be argued that domestication is a form of mutualism, where both humans and the organisms are benefited. The domestication of plants and animals by humans was a major cultural innovation ranked in importance with the conquest of fire, the manufacturing of tools, and the development of verbal language.
