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.
Centris pallida are located in dry, hot environments of North America. Specifically, they are in Arizona, Nevada, southern California, New Mexico, and western Mexico.[4] They are a very common bee (especially in Arizona), and are thus classified as Least Concern in terms of conservation.[5] The fur and dark colored exoskeleton allow the bees to survive the cold nights in the desert. During the daytime, C. pallida are almost completely inactive, hiding in shade or in burrows to prevent overheating.[6]
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]
