Phylogeny of colletid bees (Hymenoptera: Colletidae) inferred from four nuclear genes.
Colletidae comprise approximately 2500 species of bees primarily distributed in the southern continents (only two colletid genera are widely distributed: Colletes and Hylaeus). Previously published studies have failed to resolve phylogenetic relationships on a worldwide basis and this has been a major barrier to the progress of research regarding systematics and evolution of colletid bees. For ...
متن کاملRecent intron gain in elongation factor-1alpha of colletid bees (Hymenoptera: Colletidae).
We discovered the presence of a unique spliceosomal intron in the F1 copy of elongation factor-1alpha (EF-1alpha) restricted to the bee family Colletidae (Hymenoptera: Apoidae). The intron ranges in size from 101 to 1044 bp and shows no positional sliding. Our data also demonstrate the complete absence of this intron from exemplars representing all other bee families, as well as from close hyme...
متن کاملTwo continents and two names for a Neotropical colletid bee species (Hymenoptera: Colletidae: Neopasiphaeinae): Hoplocolletes ventralis (Friese, 1924)
Neopasiphaeine bees (Apoidea: Colletidae) are known for their Amphinotic distribution in the Australian and Neotropical regions. Affinities between colletid taxa in Australia and South America have been speculated for decades, and have been confirmed by recent phylogenetic hypotheses that indicate a biogeographic scenario compatible with a trans-Antarctic biotic connection during the Paleogene....
متن کاملAnalysis of family-level relationships in bees (Hymenoptera: Apiformes) using 28S and two previously unexplored nuclear genes: CAD and RNA polymerase II.
We analyzed a combined data set of two protein-coding nuclear genes (CAD and RNA polymerase II) and a nuclear ribosomal gene (28S D2-D4 region) for 68 bee species and 11 wasp outgroups. Our taxon sampling included all seven extant bee families, 17 of 20 subfamilies, and diverse tribes. Wasp outgroups included the two families most closely related to bees: Crabronidae and Sphecidae. We analyzed ...
متن کاملHistorical biogeography, divergence times, and diversification patterns of bumble bees (Hymenoptera: Apidae: Bombus).
Bumble bees (Bombus) are a cold-adapted, largely alpine group that can elucidate patterns of Holarctic historical biogeography, particularly in comparison to the alpine plants with which they likely coevolved. A recently published molecular phylogeny of bumble bees provides uniquely comprehensive species sampling for exploring historical patterns of distribution and diversification. Using this ...
