There is a size correlation which determines whether males become patrollers or hoverers. Patrollers tend to be larger so that they can better protect and copulate with emerging females. Smaller males are usually unable to compete as well, and so have to make the best out of a bad situation; thus, they become hoverers. Each group has a different set of behaviors. The patrollers move over a large space containing many other patrollers. Usually, patrollers will frequent the same spots over the course of their lives. Since the area is so large, the cost to defend it against other patrollers would be much greater than the potential mating benefits, so the patrollers show very little territoriality. Patroller males will usually only fight when a breeding female is near. In contrast, each hoverer stakes out an area of about one meter in diameter. These areas don’t overlap with other hoverers. Any fast moving object (i.e. bee, dragonfly, leaf, etc.) that enters a territory will be quickly chased. The chase allows the male bee to determine if a female is unmated, or if an enemy male is in his territory. If it is a male bee, the territory owner will chase it out, but not beyond the boundary of the territory. What is interesting is that every day (or even every several hours) the territory holder will abandon the area to establish a new zone. Often the male will never return to the vacated area, and it will be taken over by another male. This shows that hoverers show a low site tendency but strong territoriality. A balanced ratio of patrollers to hoverers is maintained, and thus, this ratio is an evolutionary stable strategy. If more males become patrollers, then the hoverers will benefit from the reduced competition, and the hoverers' genes will spread until the stable ratio is returned to. The same thing will happen if more males become hoverers.
“The number of condominiums for sale in the Greater Montréal area fell by about 22% in May. A drop like this has not been seen in nearly 15 years,” said Mathieu Cousineau, President of the GMREB Board of Directors. “With strong demand and a decrease in supply, as we have been seeing for several months now, the condominium segment – against all expectations – is on the verge of moving into a seller’s market too,” added Mr. Cousineau.
Macintosh Centris is a family of personal computers designed, manufactured and sold by Apple Computer, Inc. in 1992 and 1993. They were introduced as a replacement for the six-year-old Macintosh II family of computers; the name was chosen to indicate that the consumer was selecting a Macintosh in the center of Apple's product line. Centris machines were the first to offer Motorola 68040 CPUs at a price point around $2,500 USD, making them significantly less expensive (albeit slower) than Quadra computers, but also offering higher performance than the Macintosh LC computers of the time.
