Male C. pallida are able detect the pheromones which females release and use them to locate female burrows. When a virgin female is about to emerge from her burrow, she releases a scent that wafts up through the soil and is detected by the antenna of the males. This has led to males developing a very acute olfactory sense. Freshly-killed females have been buried to test whether sound also plays a part in male signaling. In these tests, male bees still dug up the dead females, proving that pheromone signaling is the only pathway. Males have also been observed to dig up other males. This shows that males and virgin females give off similar pheromones. Oddly, males also sometimes dig up other digger bee species. It is currently unknown why this occurs.[6]
est autocorrélée. Ainsi, un marché a des chances de baisser au cours d'une année N s'il baissait déjà au cours de l'année N-1. Réciproquement, si les prix augmentent au cours d'une année, il existe de fortes chances pour qu'ils augmentent à nouveau l'année suivante. Des périodes pluriannuelles de hausse succèdent donc, après des retournements du marché, à des périodes pluriannuelles de baisse des prix ;
Desert birds and lizards are predators of C. pallida, and these bees can be parasitized by the meloid beetle (Tegrodera erosa); however, rain is the largest threat to these bees.[12] At night and during the heat of the day, C. pallida bees will hide under rocks, trees, in burrows, etc. When it rains, the bees can get wet. If the bee is in a burrow, it may simply drown. If the bee is underneath something, when night comes, the bee may freeze to death due to the low temperatures in the desert. Since these bees are solitary, they don’t have the protection of a hive or colony; thus, they are more susceptible to the elements.[11]
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]

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.
Centris pallida are able to withstand very high internal temperatures when compared to other bees. Males regularly have thoracic temperatures of 48 to 49 degrees Celsius (118.4 to 120.2 degrees Fahrenheit). If the thoracic temperature reaches 51 to 52 degrees Celsius (123.8 to 125.6 degrees Fahrenheit), the bee will become paralyzed and die. Most of the cooling occurs when heat radiates off the abdomen. To prevent overheating, C. pallida have a very high thoracic conductance (rate of heat transfer from the thorax to the abdomen) which is 45 percent higher than that of sphinx moths of the same size. Other than this high thoracic conductance, no other mechanism has been found to help the bee reduce its internal temperature. C. pallida do not appear to have evaporative cooling in the wild as honey bees and bumblebees do.[10]

De son côté, Simon Charron, candidat de Québec solidaire (QS) dans Sainte-Rose, a indiqué que son parti construirait 50 000 logements sociaux au cours des quatre prochaines années, soit deux fois plus que l'engagement du PQ et quatre fois plus que celui du PLQ. La CAQ s'engage à construire les 16 000 logements sociaux d'ici 2024, comme prévu dans le dernier budget du gouvernement québécois.

Pages Jaunes, qui a vécu de beaux jours avec ses bottins téléphoniques, s’est recyclée de peine et de misère au fil des ans dans le numérique avec, notamment, le site Canada411.ca et DuProprio.com. Plus récemment, la compagnie a décidé de réduire ses dépenses et de recentrer ses activités afin d’améliorer sa santé financière. Dans cet esprit, Pages Jaunes a renvoyé son président et chef de la direction l'an dernier et a mis en branle, au début de l'année, un effort de consolidation qui s’est notamment soldé par la mise à pied de quelque 500 employés, soit 18 % de son personnel.
