Four varieties of bacteria have been found in the bee bread of the larva: Bacillus circulans, B. coagulans, B. firmus, and B. megaterium. Only the Bacillus genus has been found in the samples taken. Together, these four species were able to hydrolyze starch, ferment glucose, convert nitrates to nitrites, and produce dihydroxyacetone from glycerol. This group of bacteria also lowers the pH of the bee bread. These functions serve not only to protect the larva from other bacteria, but they also digest complex molecules which allow the larva to easily absorb nutrients without expending a lot of energy. The bacteria, in turn, receive a supply of food which results in a mutualistic relationship.[13]

"The condominium segment is booming. Thanks to strong sales and a sharp decrease in listings, the number of months of inventory has dropped significantly over the past year, falling from 10.2 months to 7 months," said Nathalie Bégin, President of the GMREB Board of Directors. "This segment has moved from a buyer's market to a seller's market in just one year," she added.  


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]

The two categories of behavior for C. pallida males are patrolling and hovering. These strategies are also used to find mates. In one category (the patrollers), male bees will patrol 3–6 centimeters above the ground in search of sites where buried virgin females will emerge. When a male bee finds such a site, he will dig 1–2 centimeters through the soil by gnawing at the surface with his jaws and using his forelegs to remove dirt from the excavation. If a female is found, he will attempt to mate with her either on the surface or at a nearby flower or tree. Other patrollers will sometimes attempt to steal a digging spot that another bee has found. If a bee has already found a female, another patroller bee may separate the male from the female so that it can copulate with the virgin. More often than not, the female (once found) will mate with either the male that found her or with an intruder.[6]


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]

Centris pallida typically feed on flowers that can withstand the hot temperatures of its habitat. These plants include palo verde (Cercidium microphyllum and Cercidium floridium), ironwood (Olnyea tesota), and creosote bush (Larrea divaricata).[9] The palo verde pollen is the most common, and it gives the bee bread a strong orange color.[7] Due to the large expenditure of energy by males during hovering and/or patrolling, they must consume about 3.5 times their body weight in nectar each day.[10]
Initially, the DuProprio application only featured properties for sale in a list, as it was not possible for a library to display Google Maps in a mobile app in 2009. In order to create what is now a commonplace experience for users, our team developed a custom MapKit based on Google Maps Web to display the tiles of the map. We also had to add our own implementation of touch handling and native positioning of properties, because internet performance on mobile devices was terrible at the time. This shows how incredible technological challenges are sometimes hidden behind the simplest user experiences.
A C. pallida female will find a spot for her nest. She will then dig diagonally down about 12 inches (30 cm). At the end of this tunnel, she will dig an 1 inch (2.5 cm) long vertical chamber where the egg will be laid. The chamber will be about 8 inches (20 cm) below the surface. In this chamber, the female will form a brood pot lined with wax. The brood pot will contain nectar and pollen similar to the bee bread in other bees; however, unlike other bees, the bee bread is the consistency of molasses instead of being solid.[7] The egg is laid on top of the bee bread and sealed in with wax, and the tunnel is partially filled with dirt to protect the egg.[8] A female can create several of the burrows during her lifetime.

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]
The genus Centris contains circa 250 species of large apid bees occurring in the Neotropical and Nearctic regions, from Kansas to Argentina. Most females of these bees possess adaptations for carrying floral oils rather than (or in addition to) pollen or nectar. They visit mainly plants of the family Malpighiaceae to collect oil, but also Plantaginaceae, Calceolariaceae, Krameriaceae and others. Recent studies have shown they are sister to the corbiculate bees, the most well-known and economically important group of bees [1]
L'unité de comparaison des prix de l'immobilier est généralement le prix au mètre carré (ou au pied carré, dans certains pays anglo-saxons). Pour les propriétés à revenus, on se sert de multiples du revenu et d'autres mesures reliées (taux d'actualisation). Enfin, des unités de comparaison fort variables sont aussi utilisées suivant le type de propriété (mètre cube, mètre de façade, prix à la chambre ou à l'appartement, etc.).
