A highly conserved nuclear gene for low-level phylogenetics: elongation factor-1 alpha recovers morphology-based tree for heliothine moths.
Molecular systematists need increased access to nuclear genes. Highly conserved, low copy number protein-encoding nuclear genes have attractive features for phylogenetic inference but have heretofore… Expand
Systematics and evolution of the cutworm moths (Lepidoptera: Noctuidae): evidence from two protein‐coding nuclear genes
Abstract. A broad molecular systematic survey of Noctuidae was undertaken to test recent hypotheses on the problematic definitions and relationships of the subfamilies, with special emphasis on the… Expand
Molecular phylogenetics of heliothine moths (Lepidoptera: Noctuidae: Heliothinae), with comments on the evolution of host range and pest status
Abstract The Heliothinae are a cosmopolitan subfamily of about 365 species that include some of the world’s most injurious crop pests. This study re‐assesses evolutionary relationships within… Expand
Discordant Iron-Rich Ultramafic Pegmatites in the Bushveld Complex and their Relationship to Iron-Rich Intercumulus and Residual Liquids
The iron-rich ultramafic pegmatites comprise a suite of coarse-grained rocks that form discordant bodies within the layered sequence of the Bushveld Complex. These pegmatites, which are considerably… Expand

To test its phylogenetic utility, nucleotide sequence variation in a 1,240-bp fragment of the elongation factor-1 alpha (EF-1 alpha) gene was examined in 49 moth species representing the major groups… Expand

More taxa or more characters revisited: combining data from nuclear protein-encoding genes for phylogenetic analyses of Noctuoidea (Insecta: Lepidoptera).
A central question concerning data collection strategy for molecular phylogenies has been, is it better to increase the number of characters or the number of taxa sampled to improve the robustness of… Expand
The Merensky Reef at Winnaarshoek, Eastern Bushveld Complex: A Primary Magmatic Hypothesis Based on a Wide Reef Facies
The Merensky reef on the Winnaarshoek property, in the central sector of the eastern limb of the Bushveld Complex, belongs to what may be described as a wide-reef facies, in which platinum group… Expand

THE PLATREEF OF THE BUSHVELD COMPLEX, SOUTH AFRICA: A NEW HYPOTHESIS OF MULTIPLE, NON-SEQUENTIAL MAGMA REPLENISHMENT BASED ON OBSERVATIONS AT THE AKANANI PROJECT, NORTH-WEST OF MOKOPANE
Detailed logging of relatively deep drill-core from the Akanani Project, in the northern limb of the Bushveld Complex, South Africa, has afforded new perspectives on the Platreef and its origins. In… Expand
