Phylogeny of the bee genus Lasioglossum (Hymenoptera: Halictidae) based on mitochondrial COI sequence data
- B. N. Danforth
- 1 October 1999
The bee genus Lasioglossum Curtis is a model taxon for studying the evolutionary origins of and reversals in eusociality. This paper presents a phylogenetic analysis of Lasioglossum species and… Expand
The evolution of hymenopteran wings: the importance of size
- B. N. Danforth
- 1 June 1989
This thesis was submitted to the department of Entomology and the faculty of the graduate school of the University of Kansas in partial fulfillment of the requirements for the degree of Master of… Expand
Mechanisms of spontaneous mutagenesis: an analysis of the spectrum of spontaneous mutation in the Escherichia coli lacI gene.
We have obtained via DNA sequence analysis a spectrum of 174 spontaneous mutations occurring in the lac I gene of Escherichia coli. The spectrum comprised base substitution, frameshift, deletion,… Expand
The Solitary Bees: Biology, Evolution, Conservation
Phylogeny of the bee family Melittidae (Hymenoptera: Anthophila) based on combined molecular and morphological data
The bee family Melittidae comprises a small, but biologically fascinating, group of mostly oligolectic bees, some of which are oil collecting. Phylogenetic relationships within this family are poorly… Expand
Rapid repeated cloning of mutant lac repressor genes.
We have developed a procedure to efficiently recover lac repressor mutations (lacI-) from F'lac onto a single-stranded M13 phage vector. The recovery is based on homologous recombination between… Expand
Taxonomic affinity of halictid bee fossils (Hymenoptera: Anthophila) based on geometric morphometrics analyses of wing shape
Taxonomic assignment of fossils can be difficult because descriptions and phylogenetic analyses are often based on a limited number of discrete visible morphological characters. Quantitative,… Expand
The diversification of neopasiphaeine bees during the Cenozoic (Hymenoptera: Colletidae)
The biogeography of colletid bees as a whole can be explained by several South American‐Australian trans‐Antarctic interchanges. Within Colletidae, neopasiphaeine bees form a large group that has not… Expand
Phylogenomic Analysis of Ants, Bees and Stinging Wasps: Improved Taxon Sampling Enhances Understanding of Hymenopteran Evolution
The importance of taxon sampling in phylogenetic accuracy is a topic of active debate. We investigated the role of taxon sampling in causing incongruent results between two recent phylogenomic… Expand
DNA fingerprinting data and the problem of non-independence among pairwise comparisons.
Multilocus DNA fingerprinting is commonly used to assess genetic similarity within and between geographically disjunct populations. Typically, the proportion of DNA fingerprinting bands shared… Expand
