	abstract = {<p>We describe and illustrate the male, female, and pupa of two new species of Neocorynura from the Colombian Andes, and provide information on their nesting behavior, host plants and social organization. Nests of Neocorynura iguaquensis sp. nov. Smith-Pardo \&amp; Gonzalez and N. muiscae sp. nov. Smith-Pardo \&amp; Gonzalez were found in flat or vertical banks, and contained one to three adult females. The percentage of multi-female nests varied considerably from 8.3\% to 40\% of the total of dissected nests at different times in 2000 and 2003. The ovarian development, wing and mandibular wear of females in the nests with two or more females indicated that they were the offspring that remained in the nest before dispersal or a mother and a newly emerged daughter. Pollen taken from the nest cells and scopae of museum specimens showed that both species rely heavily on pollen of asteraceans and may be active year-round. Details on the nest architecture and comments on the phylogenetic placement of both species are also provided. Direct observations on the multi-female nests are required to determine whether or not such nests contain temporary assemblages or truly semisocial colonies.</p>

	pages = {632 - 644},
	abstract = {Urbanization within the Tucson basin of Arizona during the past 50+ years has fragmented the original desert scrub into patches of different sizes and ages. These remnant patches, like the surrounding desert, are dominated by Larrea tridentata (creosote bush), a long-lived, evergreen shrub whose flowers are visited by more than 120 native bee species across its range. Twenty-one of these bee species restrict their pollen foraging to L. tridentata. To evaluate the response of this native bee fauna to fragmentation, we compared species incidence and abundance patterns for the bee guild visiting Larrea at 59 habitat fragments of known size (0.002-5 ha) and age (up to 70 years), and in adjacent desert. The 62 bee species caught during this study responded to fragmentation heterogeneously and not in direct relation to their abundance or incidence in undisturbed desert. Only a few species found in continuous desert outside the city were entirely absent from urban fragments. Species of ground-nesting Larrea specialists were under-represented in smaller fragments and less abundant in the smaller and older fragments. In contrast, cavity-nesting bees (including one Larrea specialist) were over-represented in the habitat fragments, probably due to enhanced nesting opportunities available in the urban matrix. Small-bodied bee species were no more likely than larger-bodied species to be absent from the smaller fragments. The introduced European honeybee, Apis mellifera, was a minor faunal element at >90\% of the fragments and exerted little if any influence on the response patterns of native bee species to fragmentation. Overall, native bee response to urban habitat fragmentation was best predicted by ecological traits associated with nesting and dietary breadth. The consequences for the floral host and its pollination interactions are not intuitive but await investigation.},

	abstract = {Purple prairie-clover (Dalea purpurea Ventenat) is a common perennial forb that flowers during mid-summer throughout the Great Plains and adjacent biomes. Seed of D. purpurea is used for prairie restoration. This study characterizes the reproductive biology of D. purpurea. Manual pollination field trials showed that D. purpurea has a mixed pollination system. It is primarily xenogamous (45\% of flowers manually pollinated with outcross pollen yielded plump seeds) but partially self-compatible (19\% of selfed flowers yielded seeds). Flowers neither visited by bees nor manually pollinated rarely yielded mature seed (0-6\% of flowers). A review of extensive bee community surveys from sites with prairie wildflower communities revealed that D. purpurea attracts a rich and diverse native bee fauna. Managed agricultural pollinators (Apis mellifera, Megachile rotundata) also work its flowers for pollen and nectar, yielding >20,000 seeds per plant. These observations bode well both for pollinating D. purpurea in small commercial seed fields as well as for its value for sustaining native pollinator faunas in prairie restorations.},
