Centris pallida are located in dry, hot environments of North America. Specifically, they are in Arizona, Nevada, southern California, New Mexico, and western Mexico. They are a very common bee (especially in Arizona), and are thus classified as Least Concern in terms of conservation. 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.
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 ;
They are large (up to 3 cm), fast-flying bees, distinguished from the closely related genus Epicharis by the absence of long, whip-like setae that project backwards from just behind the eyes. They are commonly encountered bees in American deserts, and are active at very high ambient temperatures when many other species are in hiding. They can often be seen in large numbers on desert-willow (Chilopsis) and palo verde (Parkinsonia) blossoms. Bees of this genus are of some economical significance in pollinating crops such as Brazil Nut (Bertholletia excelsa) and Cashew (Anacardium occidentale, pollinated by C. tarsata among others).

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.
Centris pallida serve numerous roles for the environment. Like most other bees, they are essential for pollination. Specifically, they pollinate cacti, desert willow, and palo verde. The tunneling ability of these bees aerates the soil, and this allows water from rain to reach plant roots quickly. Their nitrogen rich feces fertilizes the soil. Their stings are mild, so they are not dangerous. The only downside with respect to humans is that their burrowing can leave unsightly mounds. If an area has a large density of burrowing females, then these mounds can be quite noticeable and are difficult to get rid of.
The process of integrating the province’s various Centris databases began approximately five years ago and was completed in June 2008. All transactions concluded through a real estate broker who is a member of a real estate board are added to the new provincial database. The Québec Federation of Real Estate Boards (QFREB) uses this database to publish press releases and other publications on market conditions, including the Centris Barometer – Residential Market, which provides an overview of key performance indicators associated with the resale market (i.e., sales, new listings, median prices, number of days on the market, etc.). These indicators are calculated according to consistent, stringent rules so that statistics can be comparable across geographic areas.
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. 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. A female can create several of the burrows during her lifetime.
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.
Real estate brokers are subject to the Real Estate Brokerage Act and must comply with various measures to ensure your protection: they must meet the requirements of the Organisme d’autoréglementation du courtage immobilier du Québec (OACIQ), contribute to the Real Estate Indemnity Fund and hold professional liability insurance. They are responsible for the real estate transaction.
