Ann. Entomol. Soc. Am. 81(3): 419-427 (1988) ABSTRACT The anthophorid bee, Hahropoda (=Emphoropsis [R. W. Brooks, personal communication]) laboriosa (F.), is a locally abundant, vernal, univoltine species. It flies from February through April in Georgia and Alabama. In these states, females are oligolectic on Vaccinium spp., particularly V. ashei Reade and V. corymbosum L., with Gelsemium sempe...

The understanding of evolutionary relationships in Arctostaphylos has been hampered by taxonomic difficulties in this large and complex genus. A phylogenetic analysis of sequences from the ITS region for 38 species was used to provide a phylogenetic perspective for interpreting evolutionary patterns and relationships in Arctostaphylos. Phylogenetic relationships were estimated using maximum lik...

Phylogenetic relationships within subfamily Arbutoideae (Ericaceae) were estimated using parsimony and maximum likelihood analyses of sequence data from the ITS region and part of the large subunit of nuclear ribosomal DNA. The data support the monophyly of Arctostaphylos, Arctous, and Comarostaphylis, but suggest that Arbutus is not monophyletic, with Mediterranean Basin species more closely r...

Flavonoids are a class of secondary metabolites in plants that are involved in many important functions. Various flavonoid compounds have also been reported to be beneficial for human health. Bilberry (Vaccinium myrtillus L.) is the characteristic field layer species in boreal forests and the fruits of bilberry are rich in anthocyanin pigments, a subclass of flavonoids. In the present work, fla...
