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.
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).
Si seulement acheter une maison se résumait à apposer sa signature au bas d’un contrat. Malheureusement, il faut composer avec des modalités ou des clauses compliquées, des termes juridiques alambiqués, des exigences en matière d’inspection et de divulgation, des formulaires d’assurance qui n’en finissent plus, des règles hypothécaires qui changent sans cesse… La liste des procédures et des documents requis semble infinie. Peu importe la complexité de la transaction, un détenteur du titre REALTOR® peut vous aider à y voir clair.
