Centris pallida was officially discovered and catalogued by William J. Fox in 1899 near Phoenix, Arizona.[1] Fox also discovered Centris cockerelli, Centris errans, and Sphex subhyalinus. This species is closely related to Centris cockerelli in terms of habitat and genus, but is different in terms of mating, color, and subgenus.[2] This bee also belongs to the superfamily Apoidea, and the subfamily Apinae.[1]
The Centris 610 and 650 were replaced about six months after their introduction by the Quadra 610 and 650 models, which kept the same case and designs but raised the CPU speeds from 20 MHz and 25 MHz to 25 MHz and 33 MHz respectively; while the Centris 660AV was renamed to Quadra 660AV without any actual design change. These Macs also existed during Apple's transition from auto-inject floppy drives to manual-inject drives.[4] This is why there are two different styles of floppy drive bezel (faceplate) on these models. Some later Centris 660AV Macs have manual-inject floppy drives, so this change was not exactly concurrent with the name change.
As its partner since 2009, Mirego has created a range of digital products for the company to help future owners find their dream home. The partnership has led to a number of accomplishments over the years. In 2009, Mirego created one of the first mobile apps available in Canada and one of the first tablet apps in 2011, in both cases for DuProprio. In 2016, Mirego helped the company redesign its website.
Ne pas jeter de nourriture ou de grains de café dans le renvoi de l'évier car cela peut occasionner des senteurs ou des blocages. De plus, l'accumulation de résidus de savon, de shampoing ou de tout autre détergent à l'intérieur des tuyaux de renvoi peut occasionner des odeurs désagréables. Nous vous conseillons de bien faire couler l'eau chaude dans le renvoi après usage de ces produits nettoyants.
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.[11] 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.[11] 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.

Le patrimoine architectural de Québec comprend l'ensemble des bâtiments de l'Assemblée nationale qui ont été érigés sur la colline Parlementaire à partir de 1877. On y retrouve deux styles architecturaux, soit le style Second Empire pour l'Hôtel du Parlement et l'architecture Beaux-Arts pour les autres édifices. La Citadelle de Québec, construite entre 1820 et 1831, le Château Frontenac, bâti entre 1892 et 1893, et la Terrasse Dufferin font également partie du site patrimonial du Vieux-Québec.
