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.

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.

Larger females are able to better control the size of their offspring. As stated in the Life Cycle section, more bee bread leads to larger offspring. Larger females are able to gather more pollen and nectar in a shorter amount of time when compared to smaller females. This means that during rich conditions, the larger females can have larger offspring with greater fitness, or if conditions are poor, the females can simply choose to have smaller offspring. There is a lower limit to how small offspring can be, and thus, smaller females can’t make this reduction or increase in size in response to the environment. Smaller females are still able to exist since larger females can’t take advantage of having larger offspring when the density of nesting grounds is low.[12] To put it another way, larger male offspring are less effective in low density nesting grounds since they don’t have as many opportunities to use their size to fight off other males; thus, in low density nesting grounds, small and large males have similar fitness which means that the extra bee bread which the larger male received served no purpose. Smaller males actually do better in low density areas because they don’t have to fight with larger males as much, and by extension, expend less energy. This lack of a reason to produce larger offspring reduces the fitness of the larger females since they have to dig larger tunnels to fit in, but still produce the same size offspring as smaller females.[12]


À l’origine appelée directduproprio, l’entreprise est devenue DuProprio.com en 2004 puis DuProprio en 2011. En 2009, elle a procédé à l’acquisition de Private Real Estate, SKhomes4sale et ComFree3, d’autres entreprises canadiennes œuvrant également dans le domaine de la vente immobilière sans commission. Une fois la fusion de ces différentes entités complétée, la charte graphique de DuProprio est revue4.
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]
