Nitrogen in Insects: Implications for Trophic Complexity and Species Diversification
Using a recently compiled database on insect nutrient content, it is found that predators exhibit on average 15% greater nitrogen content than herbivores, and evidence that recently derived lineages have, on a relative basis, 15%–25% less body nitrogen than more ancient herbivore lineages.
Toward reconstructing the evolution of advanced moths and butterflies (Lepidoptera: Ditrysia): an initial molecular study
The results corroborate the broad outlines of the current working phylogenetic hypothesis for Ditrysia, demonstrate that some prominent features of that hypothesis, including the position of the butterflies, need revision, and resolve the majority of family and subfamily relationships within superfamilies as thus far sampled.
A highly conserved nuclear gene for low-level phylogenetics: elongation factor-1 alpha recovers morphology-based tree for heliothine moths.
This postulate that the single most parsimonious gene tree and the neighbor-joining tree for all nucleotides show almost complete concordance with the morphological tree for the EF-1 alpha gene in the noctuid moth subfamily Heliothinae is tested.
A Large-Scale, Higher-Level, Molecular Phylogenetic Study of the Insect Order Lepidoptera (Moths and Butterflies)
This study highlights the challenge of finding optimal topologies when analyzing hundreds of taxa and shows that some nodes get strong support only when analysis is restricted to nonsynonymous change, while total change is necessary for strong support of others.
The Phylogenetic Study of Adaptive Zones: Has Phytophagy Promoted Insect Diversification?
The adaptive-zone hypothesis predicts that if multiple lineages have invaded a new adaptive zone, they should be consistently more diverse than their (equally old) sister groups, when the latter retain the more primitive way of life.
Evolutionary Patterns of Host Plant Use by Delphacid Planthoppers and Their Relatives
Planthoppers (Homoptera: Fulgoroidea) are found on every continent except Antarctica and in all major biomes, including tropical rainforests, deserts, grasslands, and the arctic tundra (O’Brien and…
Phylogeny and Evolution of Lepidoptera.
Progress on lepidopteran phylogeny since 1975 is summarized, emphasizing the superfamily level, and some resulting advances in their understanding are discussed, to summarize the past two decades of molecular data results and discuss the resulting advances.
Systematics and evolution of the cutworm moths (Lepidoptera: Noctuidae): evidence from two protein‐coding nuclear genes
Mapping of a preliminary synopsis of species diversities, host use patterns and latitudinal distributions on the phylogeny suggests that the diversification of trifines may have been promoted, to a degree unique among Macrolepidoptera, by the Tertiary expansion of seasonal, open habitats and their associated herbaceous floras.
Escalation of Plant Defense: Do Latex and Resin Canals Spur Plant Diversification?
The evidence for Ehrlich and Raven's postulate that rapid diversification follows innovation in plant defense is quantified by comparing the diversities of lineages that have independently evolved canal systems with their sister groups for as many plant lineages as current taxonomic evidence allows.
Can Deliberately Incomplete Gene Sample Augmentation Improve a Phylogeny Estimate for the Advanced Moths and Butterflies (Hexapoda: Lepidoptera)?
This node (Gelechioidea + Apoditrysia), tentatively proposed by previous authors on the basis of four morphological synapomorphies, is the first major subset of ditrysian superfamilies to receive strong statistical support in any phylogenetic study.
